Heating Ventilation and Air-conditioning (HVAC)
Introduction to HVAC
What is HVAC?
 It controls Temperature, Humidity and Air quality inside a building.
 Especially important in medium to large buildings such as Office / Residential Towers.
 All preferably integrated into one system.
Heating – It is defined as a process of increasing the temperature of a substance or a body or a
thermodynamic system.
Heating systems are designed for colder or chilled climates.
 Central heating often used in cold climates to heat private houses and public buildings.
 Heating systems usually comprise of a boiler, furnace, heat pump, or district hot
water toheat water, steam or air.
 Piping distributes heated fluid and radiators transfer this heat to air and structures,
Ex:Floor Heating System.
Cooling – It is defined as a process of decreasing the temperature of a substance or a body or a
Thermodynamic system.
Cooling systems are designed for warmer or hot climates.
 Cooling is designed for warm climates to keep the indoor conditions as per
humancomfort.
 Cooling systems usually comprise of a chiller, indoor units like FCUs or AHUs to
coolthe room air.
 Piping distributes chilled fluid and Indoor units (IDUs) transfer the cooling to air
andstructures. Ex: Floor Cooling System.
Ventilation – It is defined as the process to maintain the Indoor Air Quality (IAQ).
 The process of ‘’changing’’ or ‘’replacing’’ air in any space to control
temperature orremove moisture, smoke, carbon dioxide etc.
 Ventilation includes both the exchange of air to the outside as well as circulation of
airwithin the building.
 It is one of the most important factors for maintaining acceptable Indoor Air
Quality inbuildings.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 2 | 74
 Supply air used for ventilation is filtered and cooled and/or heated inside Air Handling
Units.
This system is further classified into 2 sub-systems:
1. Fresh Air System: In Fresh Air System, fresh ambient air is been supplied from outdoor
environment to the indoor space to maintain oxygen requirement in the room. This air
can be partially or completely treated before been supplied to the room space.
2. Exhaust Air System: In this system, the bad or unwanted air is removed from the indoor
space to the outdoor environment.
Air-conditioning: It is defined as the process of conditioning or modification of air as per the
indoor conditions like temperature, moisture levels (humidity), dust levels, noise levels and
smell/odor.
 It refers to the cooling and dehumidification of indoor air for thermal comfort.
 Air conditioning systems are designed to stabilize the air temperature and humidity
within an area.
 Excess heat from the circulating air is usually removed by a cooling coil that is supplied
with cold water / refrigerant.
 To decrease relative humidity the circulating air needs to be cooled to a temperature
below the dew point and then heated back to meet the requirement.
 HVAC systems control the temperature, humidity, and quality of air in buildings to a set
of chosen conditions.
 The term ‘Refrigeration’ may be defined as the process of removing heat from a
substance under controlled conditions. It also includes the process of reducing and
maintaining the temperature of a body below the general temperature of its surroundings.
In other words, the refrigeration means a continued extraction of heat from a body whose
temperature is already below the temperature of its surroundings.
The basic motive of designing an HVAC system for the building industry is to maintain the
human comfort conditions inside the building space.
Human Comfort Condition:
- Temperature: 24.4o
C / 76o
F
- Relative Humidity: 50 %
- Air Quality: Fresh Air for Oxygen, Dust Filtration, Noise Criteria (NC) [25 – 50], Smell /
Odor

This human comfort conditions is as stated by ASHRAE, which stands for American Society of
Heating, Refrigeration, and Air-conditioning Engineers.
ASHRAE standards are followed worldwide for design, drafting and site installation of HVAC
systems.
Air conditioning has got wide range of applications and it is very much essential in these days.
Air conditioning is provided for some of the following reasons:
 To improve productivity in offices and factories by maintaining comfort conditions to the
people.
 To maintain comfortable conditions for working in hotels, labs, etc.
 To avoid malfunctioning of some control panels in Electrical Control Buildings.
 To maintain pressure inside the premises for avoiding outside (dusty) air in to the room.
 To create healthy atmosphere inside the room by supplying fresh and filtered air into the
room.
 To provide clean, filtered, healthy, comfortable conditions in hospitals etc.
Basic Cycle of Refrigeration:
The cycle has four basic components
1. Compressor
2. Condenser
3. Expansion valve (or) device
4. Evaporator
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 4 | 74
Compressor: The function of a compressor is to compress the fluid or gas and increase its
pressure and temperature by some mechanical action done.
Compressors are broadly classified as two types:
 Positive Displacement Compressors
 Dynamic Compressors
Condenser: Condensation is a process of change of phase from gas form to liquid form, the
same process happen inside a condenser.
A condenser converts the refrigerant gas at high pressure & temperature into a liquid refrigerant
at nearly high pressure & temperature by releasing the latent heat from the gas.
Condensers are broadly classified as
 Air Cooled
 Water Cooled
 Air and Water Cooled (or) Evaporative Condenser
Expansion Device: The function of expansion device is to decrease the pressure & temperature
of the liquid refrigerant by the process of expansion.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 5 | 74
Types of Expansion Devices:
 Capillary Tubes
 Thermostatic Expansion Valves
 Electronic Expansion Valves
Evaporator: Evaporation is a process of change of phase from liquid to gas form, the same
process happens inside an evaporator.
The evaporator converts the liquid refrigerant at low pressure & temperature into its gaseous
form by absorbing the latent heat from the room air.
Types of Evaporators:
 Air Cooled
 Water Cooled
Refrigerants: Refrigerants are the heat transfer media used in the refrigeration cycle, which
absorb heat from the room air during the process of evaporation at a region of low-pressure &
temperature and releases the heat during the process of condensation at a region of high pressure
& temperature.
Ex: Air, Water, Refrigerants like R-12, R-22, R-134a, R-410a, NH3, LiBr3 (They have very low
boiling point)
Basic Refrigeration Cycle (In Detail)
Principles of Refrigeration:
 Liquids absorb heat when changed from liquid to gas.
 Gases give off heat when changed from gas to liquid.
Working of Refrigeration Cycle:
1. The refrigerant comes into the compressor as a low pressure gas, it is compressed and
then moves out of the compressor as a high pressure gas.
2. The gas then flows to the condenser. Here the gas condenses to a liquid and gives off its
heat to the outside air.
3. The liquid then moves to the expansion valve under high pressure. This valve restricts the
flow of the fluid, and lowers its pressure as it leaves the expansion valve.
4. The low pressure liquid then moves to the evaporator, where heat from the inside air is
absorbed and changes it from a liquid to a gas.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 6 | 74
5. As a hot low-pressure gas, the refrigerant moves to the compressor where the entire cycle
is repeated.
Components of Refrigeration Cycle:
S.No. Name of Component Function
1 Compressor Increases the pressure and temperature of the gas by
mechanical work done.
2 Condenser Change of phase from Gas to Liquid. Heat is rejected to
atmosphere from the R-gas.
3 Expansion Device Decreases the pressure and temperature of the gas by
expansion.
4 Evaporator Change of phase from Liquid to Gas. Heat is absorbed by
R-gas from the indoor space.
Compressor:
 The purpose of the compressor is to circulate the refrigerant in to the system under
pressure.
 At the compressor, the low pressure gas is changed to high pressure gas.
 The compressor has reed valves to control the entrance and exit of refrigerant gas during
the pumping operation.
Types of Compressors:
1. Positive Displacement
a. Reciprocating – Single-Acting, Double-Acting, Diaphragm
b. Rotary – Lobe, Liquid Ring, Screw, Scroll, Vane
2. Dynamic
a. Centrifugal
b. Axial
Reciprocating Compressor:
 A reciprocating compressor is also known as Piston Compressor.
 The reciprocating compressor uses a piston, which moves inside a cylinder, to compress
the air.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 7 | 74
 When the piston moves down, air is drawn in. When the piston moves up, the air is
compressed.
 We have different types of reciprocating compressors:
1. Single-Acting Compressors:
 These are usually reciprocating compressors which has piston working only in one
direction.
 The other end of the piston is open which does not perform any work.
 The air is compressed only on the top part of the piston.
 The bottom of the piston is open to crankcase and not utilized for the compression of air.
2. Double-Acting Compressors
 These compressors are having two sets of suction and delivery valves on both sides of the
piston.
 As the piston moves up and down, both sides of the piston is utilized in compressing the
air.
 Thus both sides of the pistons are effectively used in compressing the air.
3. Diaphragm Compressors
 Diaphragm Compressor is a kind of displacement compressors driven by electromotor.
 Diaphragm Compressor contains two chambers in each cylinder body, i.e.
1. Hydraulic Oil Chamber
2. Gas Chamber
Rotary Compressors:
 They are different from the reciprocating compressors.
 They does not have any pistons and crankshaft.
 These compressors have Screws, Vanes, Scrolls and other devices which rotate and thus
compress air.
 The rotary compressors are classified into Screw type, Vane type, Lobe type, Scroll type
and other types.
Centrifugal Compressors:
 The centrifugal air compressor which depends on transfer of energy from a rotating
impeller to the air.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 8 | 74
 Centrifugal compressors produce high-pressure discharge by converting angular
momentum imparted by the rotating impeller (dynamic displacement).
 Centrifugal compressors rotate at higher speeds than the other types of compressors.
Axial Flow Compressors:
 An Axial flow compressor is a pressure producing machine. It is a rotating based
compressor in which the working fluid principally flows parallel to the axis of rotation.
 A shaft derives a central drum, retained by bearings, which has a number of annular
airfoil rows attached usually in pairs, one rotating and one stationary attached to a
stationary tubular casing.
 The rotating airfoils also known as blades or rotors, which accelerate the fluid.
Condenser:
 The purpose of the condenser is to receive the high-pressure gas from the compressor and
convert this gas to a liquid.
 Air passing over the condenser coils carries off the heat and the gas condenses.
 The condenser often looks like an engine radiator.
 Condensers used on R-12 and R-134a.
Types of HVAC Condensers:
 There are three types of HVAC condensers that depending on the cooling method that
they used.
 An HVAC condenser is an important part of your cooling system.
 Condensers can either be
1. Water-cooled Condenser
2. Air-cooled Condenser
3. Air and Water-cooled Condenser (Evaporative type)
Water-cooled Condenser:
 A Water-cooled condenser works by moving water through the annular space between
the tubes or coils.
 Water acts as the cooling medium.
 Water-cooled condensers require a constant supply of water to prevent corrosion.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 9 | 74
 Types of Water-cooled Condensers:
a. Double Pipe Condenser
b. Double Tube Condenser
c. Shell and Coil Condenser
d. Shell and Tube Condenser
Cooling Tower:
 Cooling Towers are heat removal devices used to transfer waste heat to the atmosphere.
 Cooling towers are required for recirculation of condenser water.
 The warm water being pumped by the condenser should be cooled with the help of
cooling towers, so that the same water may be re-circulated to the condenser.
 Types of Cooling Towers: According to the method adopted to circulate the air, cooling
towers may be classified as:
a. Natural Draft Cooling Towers – The air is circulated inside the cooling tower by
natural convection. The natural draft cooling towers are further classified as: Spray
Type and Splash Deck Type.
b. Mechanical Draft Cooling Towers:
 The Mechanical Draft Cooling Towers are similar to Natural draft cooling towers, but the
air is circulated inside the tower MECHANICALLY. Propeller fans or centrifugal fans
may be used.
 Mechanical draft cooling towers are much smaller than the natural draft cooling towers.
 They are further classified as:
a. Forced Draft Cooling Towers – A fan is located near the bottom and on the side. This
fan forces the air from bottom to top.
b. Induced Draft Cooling Towers – A fan is located at the top, takes suction from the
tower and discharges it to the atmosphere.
Air-cooled Condenser:
 Cooling medium is ambient air.
 It is used where there is of water scarcity.
 Air-cooled condensers are designed for mostly residential applications and for small
offices.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 10 | 74
 An Air-cooled condenser is designed to move the air over the condenser coil using either
a fan or at times a natural draft.
 Finned coil-copper tubes & aluminum fins.
 Refrigerant is inside the tubes.
 Regular cleanings will greatly improve their efficiency and reduce wear and tear.
Air and Water-Cooled Condenser (Evaporative Condenser):
 Condensers that use a combination of air and water cooling are often referred to as
evaporative condensers.
 These are often used in large commercial cooling units.
 In this condenser, water is sprayed from above onto the coils as air is blown from below.
 This causes a cooling effect that condenses the refrigerant inside the coils.
 Evaporative units generally do not waste water so they are a good choice in areas where
water is scarce.
Expansion Devices (or) Valves:
 Expansion valve which expands the liquid refrigerant to lower its pressure and
temperature before the refrigerant enters the evaporator.
 It also regulates the flow of refrigerant in to the evaporator.
 Expansion valves do not control humidity.
 Expansion valves can be put into three categories:
1. Capillary Tube
2. Thermostatic Expansion Valve (TX valve)
3. Electronic Expansion Valve (EX valve)
Evaporator:
 The evaporator is a kind of heat transfer apparatuses where the heat transfer is done by
forced convection or natural convection.
 In the evaporator, a very large amount of heat is absorbed from surrounding (the indoor
air) causing the liquid refrigerant to boil and turn into a gas phase.
 The gas is passed to compressor to repeat the cycle again until the indoor air be
comfortable and sufficiently cool.
 Types of Evaporators:
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 11 | 74
An Evaporator is used in an air-conditioning system to allow the refrigerant such as R-22
to evaporate from liquid to gas while absorbing heat in the process.
In concept, an evaporator is similar to condenser, except an evaporation process occurs in
an evaporator.
1. Shell and Tube Evaporator
a. Shell and Tube with the Refrigerant Boiling in Shell
b. Shell and Tube with the Refrigerant Boiling in Tubes
2. Plate Type Evaporator
REFRIGERANTS:
 ‘’Refrigerant is the fluid used for heat transfer in a refrigerating system that absorbs heat
during evaporation from the region of low temperature and pressure, and releases heat
during condensation at a region of higher temperature and pressure’’.
 Example: Air, Water, Refrigerant gases like R-22, R-134a, R-410a etc.
 HCFC-22 (or) R-22:
Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon
(HCFC). This colorless gas is better known as HCFC-22 or R-22.
The boiling point of R-22 is -41.3o
F (at atmospheric pressure 14.7 psia, 1 bar abs)
 R-134A:
1, 1, 1, 2-Tetrafluoroethane, R-134a, Forane 134a, Genetron 134a, Suva 134a or HFC-
134a. It is a haloalkane refrigerant with thermodynamic properties similar to R-12
(dichlorodifluoromethane) but with less ozone depletion potential. It has the formula
CH2FCF3 and boiling point of -26.3o
C (-15.34o
F) at atmospheric pressure.
 R-410A:
R-410A, sold under the trademarked names Forane 410A, Puron, Ecofluor R410,
Genetron R410A, and AZ-20, is a zeotropic, but near-azeotropic mixture of
difluoromethane (CH2F2, called R-32) and pentafluoroethane (CHF2CF3, called R-125),
which is used as a refrigerant in air conditioning applications.
The boiling point of R-410A is -55.4o
F (at atmospheric pressure 14.7 psia, 1 bar abs)
 NH3:
Ammonia or ozone is a compound of nitrogen and hydrogen with the formula NH3.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 12 | 74
Ammonia as used commercially, is often called anhydrous ammonia, because NH3 boils
at -33.34C
C (-28.02o
F) at a pressure of 1 atmosphere, the liquid must be stored under high
pressure or at low pressure.
Criteria for Refrigerant Selection:
Some of the desirable characteristics for a widely used refrigerant include:
 Environmental acceptability
 Materials Compatibility
 Chemical Stability
 Refrigeration-cycle performance
 Adherence to nonflammable and nontoxic guidelines
 Boiling Point
Classification of Air Conditioning Systems
Based on the fluid media used in the thermal distribution system, air conditioning systems can be
classified as:
1. All Air Systems
2. All Water Systems
3. Air-Water Systems
4. Unitary Refrigerant Based Systems
All Air Systems:
In this system, air is used as the media that transports energy from the conditioned space to the
A/C plant. In these systems air is processed in the A/C plant and this processed air is then
conveyed to the conditioned space through insulated ducts using blowers and fans.
It is further classified into 2 sub-systems:
1. Single Duct System – It can provide either cooling or heating using the same duct, but
not both heating / cooling simultaneously.
2. Dual Duct System
All Water Systems:
In this systems, the fluid used in thermal distribution system is water i.e. water transports energy
between the conditioned space and the A/C plant. When cooling is required in the conditioned
space then cold water is circulated between the plant & the conditioned space, while hot water is
circulated through the distribution system when heating is required.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 13 | 74
It is further classified into 2 sub-systems:
1. 2 Pipe System – It is used either cooling or heating only application, but cannot be used
for simultaneous cooling and heating.
2. 4 Pipe System – It consists of two supply pipelines – one for cold water and one for hot
water, and two return water pipelines.
Air-Water Systems:
In this system, both air and water are used for providing required conditions in the conditioned
space. The air and water are cooled or heated in a central plant. The air supplied to the
conditioned space from the central plant is called as primary air, while the water supplied from
the plant is called as secondary water. The complete system consists of a central plant for cooling
or heating of water & air, ducting system with fans for conveying air, water pipelines and pumps
for conveying water and a room terminal. The room terminal may be in the form of a FCU, an
induction unit or a radiation panel.
Unitary Refrigerant Systems:
It consist of several separate air conditioning units with individual refrigeration systems. These
systems are factory assembled and tested as per standard specifications and are available in the
form of package units of varying capacity and type. Each package consists of a refrigeration and
/ or heating units with fans, filters, controls etc.
Heat Load Calculation (or) Estimation
Heat – it is a form of energy which can be neither created nor destroyed, but changes its form
from one to another.
Heat can be measured in terms of British Thermal Units (BTU).
BTU – 1 BTU is an amount of heat required to raise the temperature of 1 pound of water by 1o
F.
TR – 1 TR is an amount of cooling given by 1 ton of ice kept in a room of dimensions 10’ x 10’
x 10’ in the next 24 hours.
1 TR = 12000 BTU
1 TR = 3.513 KW
1 TR = 3.41 BTU/hr
Heat Load Calculation – It is a mathematical procedure of calculating or determining the
amounts of heat which can get generated inside the building through internal & external sources
of heat. This heat has to be removed from the building space to maintain a set of cooling
conditions or in other words provide cooling to the room space to maintain the indoor conditions.
This is measured in terms of TR (Tons of Refrigeration).
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 14 | 74
Sources of Heat:
1. External Sources
a. Sun – Wall, Glass, Roof, Partition
b. Air – Ventilation, Infiltration
2. Internal Sources
a. People
b. Lighting (Watts)
c. Equipment (KW)
Purpose of Load Calculations:
Load calculations can be used to accomplish one or more objectives:
1. Provide information for equipment selection and HVAC system design.
2. Provide data for evaluation of the optimum possibilities for load reduction.
3. Permit analysis of partial loads as required for system design, operation and control.
These objectives can be obtained not only by making accurate load calculations but also by
understanding the basis for the loads, where a brief description of cooling and heating loads is
included.
Building Survey
Principles of Cooling Loads:
In air-conditioning design there are three distinct but related heat flow rates, each of which varies
with time.
1. Heat Gain or Loss
2. Cooling load or Heating load
3. Heat Extraction or Heat Addition Rate
Heat Gain – It is the rate at which heat enters or is generated within a space at a given instant of
time. There are two ways that heat gain is classified. They are the manner in which heat enters
the space and the type of heat gain.
The manner in which a load source enters a space is indicated as follows:
1. Solar radiation through transparent surfaces such as windows.
2. Heat conduction through exterior walls and roofs.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 15 | 74
3. Heat conduction through interior partitions ceilings and floors.
4. Heat generated within the space by occupants, lights, appliances, equipment and
processes.
5. Load as a result of ventilation and infiltration of outside air.
6. Other miscellaneous heat gains.
The types of heat gain are sensible and latent. Proper selection of cooling and humidifying
equipment is made by determining whether the heat gain is sensible or latent.
The sensible cooling load is defined as the rate at which heat must be removed from the space to
maintain the room air temperature at a constant value.
The actual total cooling load is generally less than the peak total instantaneous heat gain thus
requiring smaller equipment than would be indicated by the heat gain.
Heat extraction is the rate at which heat is removed from the conditioned space.
Diversity of Cooling Loads:
Diverting of cooling load results from not using part of the load on a design day. Therefore,
diversity factors are the factors of usage and are applied to the refrigeration capacity of large air-
conditioning systems. These factors vary with location, type, size of applicant based entirely on
the judgement and experience of the engineer.
Generally, diversity factors can be applied on loads from people and lights; there is neither 100%
occupancy nor total lighting at the time of such other peak loads as peak solar and transmission
loads. The reductions in cooling loads from non-use are real and should be accounted for. In
addition to the factors for people and lights, a factor should also be applied to the machinery load
in industrial buildings. It is advisable to measure the power input whenever possible as this will
provide a diversity factor. It is also possible to determine a diversity factor for a large existing
building by reviewing the maximum electrical demand and monthly energy consumption
obtained from the utility bills.
Principles and Procedures for Calculating Heating Load
1. Information Required (Inputs) – Before a cooling or heating load can be properly
estimated a complete survey must be made of the physical data. The more exact the
information that can be obtained about space characteristics, heat load sources, location
of equipment and services, weather data, etc. the more accurate will be the load estimate.
2. Required Input – External Loads – Cooling: For calculation of the outdoor loads, the
input information should include:
a. Orientation and dimensions of building components.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 16 | 74
b. Construction materials for roofs, walls, ceiling, interior partitions, floors and
fenestration.
c. Size and use of space to be conditioned.
d. Surrounding conditions, outdoors and in adjoining spaces.
3. Film Coefficient – In addition to the resistance of the various components of a barrier, we
have to consider one more resistance offered by a film of air (or fluid if the barrier is a
fluid) which clings on to the barrier surfaces. This resistance is more when the air is still
and is relatively less when there is wind velocity.
Outside Film Coefficient (RO) = 0.25
Inside Film Coefficient (RI) = 0.65
4. Storage Effect – Suppose “TO” is the temperature on both sides of the barrier. There will
be no heat transmission through the barrier and the temperature at all points within the
barrier will also be the same. Therefore, no temperature gradient. The walls take about 2
hours approximately to start conducting the heat onto the inside space.
5. Attic Spaces – Whenever a false ceiling is provided in a room, the space enclosed
between the false ceiling and the concrete ceiling is called ATTIIC SPACE. If the attic
space is not ventilated the entire space within the attic will assume an intermediate
temperature which will be more than the room temperature and less than the outside
temperature.
Procedure for Heat Load Estimation
 Collect architect drawings for the building giving all the details and dimensions of walls,
floors, windows, etc. If such drawings are not available, survey the place and get the
particulars.
 For every applications, there are certain things which the ultimate user has to specify.
These are:
a. Temperature & humidity conditions to be maintained inside the space and tolerance.
b. Occupancy – i.e., maximum no. of people likely to occupy the space and the nature of
their activity.
c. Lighting load and other internal source of heat generation.
d. Period of operation – ex: 8 AM to 4 PM or 10 AM to 8 PM etc.
e. For industrial application you require the HP load in the conditioned space and
diversity factor thereon.
f. Minimum ventilation required.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 17 | 74
 Outside Design Conditions:
1. For comfort air conditioning application, use the mean maximum DB temperature &
the WB temperature which occurs simultaneously with the assumed DB.
2. For industrial applications where temperatures and humidity are to be maintained
within very close tolerance through the year, take the maximum DB and the
simultaneously occurring WB temperature.
 For all applications make a second load estimate for monsoon conditions.
 For applications where the conditioned spaces are spread over very vast floor areas,
divide the entire area into convenient zones and make load estimates.
 Occupancy – In certain applications a diversity factor may have to be used even in
respect of occupancy. Examples are: Office areas where a separate conference room is
also provided. The conference room may be designed for a large number of people. But
you must realize that it is mostly the people in the office who go into conferences and
hence any occupancy in the conference room brings about an equal reduction in the
occupancy in other areas of the office.
 Typical Diversity Factors for Largest Buildings:
Type of Application Diversity Factor for People Diversity Factor for Lights
Office 0.75 to 0.90 0.70 to 0.85
Apartment, Hotel 0.40 to 0.60 0.30 to 0.50
Department Storage 0.80 to 0.90 0.90 to 1.0
Industrial 0.85 to 0.95 0.80 to 0.90

Relative Humidity = 28%
Tc = (5/9)*(Tf-32)
Where, Tc = Temperature in degree Celsius
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 18 | 74
Tf = Temperature in degree Fahrenheit
Inside Design Conditions:
Inside design condition is a combination of the temperature and the relative humidity within the
subjected building structure or the favorable conditions required within the building structure as
per standards / clients.
Inside Conditions:

Relative Humidity = 50%
Heat Load Estimation
The basic formula for Heat Load Calculation/Estimation,
Q = U A T
Where, Q = Quantity / Rate of Heat Transfer (Btu/hr)
U = Coefficient of Heat Transfer (Btu/hr Ft2 o
F)
A = Area of Cross-section (Sqft)
T = Temperature Difference (o
F)
Coefficient of Heat Transfer:
The U-factor for each of the type of wall is calculated according to the thickness of the wall and
its thermal resistance value of each material, using the formula.
U = 1/Sum of All Resistances (R) of materials inbuilt in the wall structure.
Sum of all resistances = RO + X1R1 + X2R2 +................+ XnRn + Ri
Where,
X1.................Xn are the thickness of the each material
R1 ................ Rn are the resistance of the material
RO = Outside Air Film Coefficient
Ri = Inside Air Film Coefficient
Area Calculations:
The area of each wall or window can be calculated by simple mathematical calculations, and can
be used for the Heat Load Estimate.

Modes of Heat Transfer
There are three modes of heat transfer:
a. Conduction: It is the transfer of heat from one part of a substance to another in
physical contact with it, without appreciable displacement of molecules forming
the substance.
Conduction takes place in solids, liquids and gases.
b. Convection: It is the transfer of heat within a fluid by mixing of one portion of
fluid with another, there is an appreciable movement of the molecules of the fluid.
Natural convection takes place due to density difference.
Forced convection takes place by doing work (blowers, pumps, etc.)
Convection takes place in gases and liquids.
c. Radiation: It is the transfer of heat in space in form of electro-magnetic waves or
quanta. Radiation does not need medium it can pass thru vacuum.
Psychrometry:
The area of measuring the moisture content of air is termed as Psychrometry.
Psychometrics:
It is a science involving the study of air and the moisture present in the air (properties of air) with

FAN BASICS
Fans:
A fan is a power driven rotary machine which causes a continuous flow of air. A fan has rotating
bladed impeller. The blades exert force on the air, raising its pressure and maintaining a
continuous flow.
A fan may be ‘directly driven’ or ‘belt driven’.
AIR DISTRIBUTION SYSTEM
DUCT BASICS:
Duct:
A duct can be described as a device used to provide an isolation path to carry an item from one
place to other place without bringing the product in contact with the atmosphere before the
delivery point.
The major purpose of a duct is to carry the air from one point to the other without bringing it in
contact with the outside atmosphere. This can be either supply air or return air.

10. Supply Air Diffuser
11. Return Air Diffuser
Supply Air:
It is defined as the conditioned air being supplied from the air conditioner outlet. The air is
treated air & contains all the desired qualities as provided by the air.
Return Air:
It is defined as the air being supplied back to the air conditioner from the air conditioned space.
This air is returned back to the air conditioner after being circulated in the conditioned space.
Fresh Air:
It is defined as the ambient air being supplied to the air conditioner inlet from the outside
atmosphere. This air is supplied to the air conditioner inlet from the outside atmosphere after
being initially treated.
Types of Pressure
1. Total Pressure
2. Static Pressure
3. Velocity Pressure
Total Pressure = Static Pressure + Velocity Pressure
 Static pressure is measured perpendicular to the direction of flow of the air. It may be
positive or negative.
 Velocity pressure: The pressure due to velocity of the air flowing in a duct is termed as
velocity pressure. It is always positive and always exerted in the direction of flow.
Velocity Pressure = Total Pressure – Static Pressure
Aspect Ratio:
Aspect Ratio = Long Side of Duct / Short Side of Duct
(Or)
= Width of the Duct / Height of the Duct
Best Aspect Ratio is 1:1
Maximum permissible Aspect Ratio is 4:1
 In Rectangular ducts the best aspect ratio is 1:1 i.e. 1. As the Aspect ratio increases the
friction per running feet of the duct increases due to increase in surface area.

VENTILATION SYSTEMS
It is defined as a process to maintain the indoor air quality as per the people or process comfort
within the building space.
These systems is further classified into 2 sub-systems:
1. Fresh Air System
2. Exhaust Air System
Fresh Air Systems
In this system, fresh ambient air is supplied from the outdoor environment to the indoor space to
maintain the oxygen requirement in the room. This fresh air can be partially or completely
treated before being supplied to the room space. In centralized HVAC systems, the fresh air can
be supplied by multiple procedures.
1. Fresh Air Fan (FAF) System: (Used for Residential)
In this system, fresh ambient air is supplied by fresh air fans (Centrifugal, Inline Fans) from the
outdoor space to the entire building and released behind the FCU through the FAD system (FAD
– Fresh Air Ducting System)
 The terminal device used to release the fresh air behind the FCU is BELL MOUTH.
 This FCU further cools the air and supplied to each room space through Supply Air
Ducting System (SAD).
 Fresh Air = Ventilation (CFM)
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 40 | 74
2. AHU System: (Used for Commercial)
In this system, the fresh air is supplied through a terminal device called as FRESH AIR
LOUVER and mixed along with a return air either in the ducting system or in the mixing
chamber of the AHU. The AHU further filters, cools the air & supplied through the SAD system.
3. FAHU System: (Used for Commercial – Hospitals)
In this system, a separate or dedicated AHU called as FAHU (Fresh Air Handling Unit) is used
to supply fresh ambient air to each building space. The FAHU takes the fresh air, filters and
cools it and supply to the each room space through FAD system having separate fresh air
diffusers.
 The FAHU systems is used for precise supply of fresh air, it is an independent system.
 The selection and capacity of the FAHU is depend on the entire fresh air load of the
project.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 41 | 74
Exhaust Air Systems
 In this system, the bad or unwanted air is been removed from the indoor spaces like
kitchens, washrooms & toilets, and exhausted to the outdoor environment. This air may
or may not be reused for any kind of heat recovery options depending on the efficiency &
savings.
 Toilets & Washrooms
1. As per Fixtures

4. Efficiency
5. Horse Power
6. Impeller Diameter
HEAD:
 It is a measure of the pressure a pump develops.
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 54 | 74
 It describes capability of the pump to handle the resistance to flow expressed in ‘ft.’
water column.
 1.03 kg/m2
= 10 m of water = 14.7 psia
(Or)
100 Ft of Water = 44.78 psia
PUMP LAWS:
Flow rate, Q is directly proportional to Pump Speed (RPM)
Head, H is directly proportional to Pump Speed (RPM)2
Power, P is directly proportional to Pump Speed (RPM)3
 Control of pump RPM to vary flow rate can provide lot of energy saving.
 At reduced load, 50% reduction in flow rate will translate to 87.5% reduction in power.
Pump Selection:
Pump selection is based on two factors:
1. GPM (Volume Flow Rate of Water)
2. HEAD (psi / ft. of water)

Testing, Adjusting & Balancing (TAB) is done as per final handover requirements.
Testing, Adjusting & Balancing (TAB) operation:
The phrase testing, adjusting and balancing (TAB) has become popular. As a description of what
is commonly called balancing.
Testing is the process of operation & checking the performance of equipment.
Balancing is the process of proportioning the correct flow of air & water throughout the system.
Such as through mains, branches, equipment & terminal units.
Adjusting is the process of regulating & setting the variable so that a balance system is achieved.
The variable may be speed, temperature, pressure, flow rate, etc. Some devices that control a
variable for example, a valve may be regulated to adjust flow rate in the process of balancing.
Instrumentation:
The success of the TAB operation depend on accurate instrumentation. These instrument are
used for measuring temperature, pressure, velocity, flow rates, speed, heat flow & electrical
energy.
Instrument have varied degree of accuracy. For TAB work as accuracy within 5% of the true
value is more than sufficient and is usually available in the market.
Instrument should be always calibrated before each use.
Measurement of Temperature:
Thermometer with an accuracy of + (or) – 0.5o
C or + (or) – 1o
C are suitable for HVAC work.
Measurement of Pressure:
MOHAMMED ABDUL RAZZAK HVAC CLASS NOTES
P a g e 72 | 74
Manometer are simple and accurate pressure measuring instrument which utilize the pressure
that will lift a column of liquid. Water or mercury are the two common liquid used. The U-Tube
Manometer is the simplest arrangement. One end of the manometer is connected to the location
where pressure is to be measured, and other is usually open to the atmosphere. The reading on
the manometer is therefore gauge pressure.
Bourdon Pressure Gauge: It is a most commonly used type for installation in pipeline & in
vessels. This type of gauge is rugged & reliable and relatively in-expensive. It is not suitable for
reading very small pressure differences.
Measurement of Velocity:
For very approximate air velocity steady smoke can be use. The smoke generated by a
mechanical device or candles (smoke emitters) is injected in the air stream and absorb more
practical use of smoke is to examine the air distribution pattern in a room & to find air leakages
in ducts.
Silicon sealant is used to close the duct leakage.
Anemometer & Pilot Tube are most frequently used for measuring air velocities.
Client Handover:
Project handover to client after commissioning of the project, as per project specifications.

Nomenclature of Refrigerant:-
Most of the refrigerants of methane and ethane series are designated by their
number instead of their chemical names. A commonly used number system
was developed. The refrigerants are internationally designated as R11, R12
etc.
 A refrigerant followed by a two digit number indicates that it is derived
from methane base and that by three digit number represents ethane
base.
 The method of number system is as follows:
(a) The first digit on the right is the number of fluorine (F) atoms in the
refrigerant.
(b) The second digit from the right is one more than the number of
hydrogen (H) atoms presents.
(c) The third digit from the right is one less than the number of carbon
(C) atoms, but when this digit is zero, it is omitted.
(d) The number of chlorine (Cl) atoms is found by subtracting the sum
of fluorine and hydrogen atoms from the total number and they can
be attached to carbon. With one carbon, the total number of attached
atoms is four. With two carbons, the total number is six.
(e) In some cases, instead of chlorine atoms, bromine atoms are used
with letter B.
(f) The azeotropic refrigerants are designated by 400 or 500 series.
(g) Hydrocarbon refrigerants except butane and isobutene are included
in the 600 series.
(h) Organic refrigerants are included in the 600 series whereas inorganic
refrigerants are in 700 series.

(i) When two or more inorganic compounds have same molecular
weights, the letter A, B, C etc. are used to distinguish among them.
 The general chemical formula for the refrigerant either for methane or
ethane base is given as
CmHnFpClq
Where, m – Number of carbon atoms
n – Number of hydrogen atoms
p – Number of fluorine atoms
q – Number of chlorine atoms and
n+p+q = 2m+2
Commercially, the refrigerants are designated as R (m-1) (n+1) P
E.g.:- (I) CCl3F
Here,
m=1, n=0, p=1, q=3
Its commercial name = R (m-1) (n+1) P
= R (1-1) (0+1)1
= R11
(II) C2Cl2F4
Here,
m=2, n=0, p=4, q=2
Commercial name = R (m-1) (n+1) P
= R (2-1) (0+1)4
= R114
Functions of Expansion Valve:-
 Expansion valve reduces the high pressure liquid refrigerant to low
pressure liquid refrigerant before being fed to the evaporator.
 Expansion valve maintains the desired pressure difference once
between the high and low pressure sides of the system, so that the
liquid refrigerant vaporizes at the designed pressure in the evaporator.
 Expansion valve controls the flow of refrigerant according to the load
on the evaporator.

    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 1 | 74 Heating Ventilation and Air-conditioning (HVAC) Introduction to HVAC What is HVAC?  It controls Temperature, Humidity and Air quality inside a building.  Especially important in medium to large buildings such as Office / Residential Towers.  All preferably integrated into one system. Heating – It is defined as a process of increasing the temperature of a substance or a body or a thermodynamic system. Heating systems are designed for colder or chilled climates.  Central heating often used in cold climates to heat private houses and public buildings.  Heating systems usually comprise of a boiler, furnace, heat pump, or district hot water toheat water, steam or air.  Piping distributes heated fluid and radiators transfer this heat to air and structures, Ex:Floor Heating System. Cooling – It is defined as a process of decreasing the temperature of a substance or a body or a Thermodynamic system. Cooling systems are designed for warmer or hot climates.  Cooling is designed for warm climates to keep the indoor conditions as per humancomfort.  Cooling systems usually comprise of a chiller, indoor units like FCUs or AHUs to coolthe room air.  Piping distributes chilled fluid and Indoor units (IDUs) transfer the cooling to air andstructures. Ex: Floor Cooling System. Ventilation – It is defined as the process to maintain the Indoor Air Quality (IAQ).  The process of ‘’changing’’ or ‘’replacing’’ air in any space to control temperature orremove moisture, smoke, carbon dioxide etc.  Ventilation includes both the exchange of air to the outside as well as circulation of airwithin the building.  It is one of the most important factors for maintaining acceptable Indoor Air Quality inbuildings.
  • 2.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 2 | 74  Supply air used for ventilation is filtered and cooled and/or heated inside Air Handling Units. This system is further classified into 2 sub-systems: 1. Fresh Air System: In Fresh Air System, fresh ambient air is been supplied from outdoor environment to the indoor space to maintain oxygen requirement in the room. This air can be partially or completely treated before been supplied to the room space. 2. Exhaust Air System: In this system, the bad or unwanted air is removed from the indoor space to the outdoor environment. Air-conditioning: It is defined as the process of conditioning or modification of air as per the indoor conditions like temperature, moisture levels (humidity), dust levels, noise levels and smell/odor.  It refers to the cooling and dehumidification of indoor air for thermal comfort.  Air conditioning systems are designed to stabilize the air temperature and humidity within an area.  Excess heat from the circulating air is usually removed by a cooling coil that is supplied with cold water / refrigerant.  To decrease relative humidity the circulating air needs to be cooled to a temperature below the dew point and then heated back to meet the requirement.  HVAC systems control the temperature, humidity, and quality of air in buildings to a set of chosen conditions.  The term ‘Refrigeration’ may be defined as the process of removing heat from a substance under controlled conditions. It also includes the process of reducing and maintaining the temperature of a body below the general temperature of its surroundings. In other words, the refrigeration means a continued extraction of heat from a body whose temperature is already below the temperature of its surroundings. The basic motive of designing an HVAC system for the building industry is to maintain the human comfort conditions inside the building space. Human Comfort Condition: - Temperature: 24.4o C / 76o F - Relative Humidity: 50 % - Air Quality: Fresh Air for Oxygen, Dust Filtration, Noise Criteria (NC) [25 – 50], Smell / Odor
  • 3.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 3 | 74 This human comfort conditions is as stated by ASHRAE, which stands for American Society of Heating, Refrigeration, and Air-conditioning Engineers. ASHRAE standards are followed worldwide for design, drafting and site installation of HVAC systems. Air conditioning has got wide range of applications and it is very much essential in these days. Air conditioning is provided for some of the following reasons:  To improve productivity in offices and factories by maintaining comfort conditions to the people.  To maintain comfortable conditions for working in hotels, labs, etc.  To avoid malfunctioning of some control panels in Electrical Control Buildings.  To maintain pressure inside the premises for avoiding outside (dusty) air in to the room.  To create healthy atmosphere inside the room by supplying fresh and filtered air into the room.  To provide clean, filtered, healthy, comfortable conditions in hospitals etc. Basic Cycle of Refrigeration: The cycle has four basic components 1. Compressor 2. Condenser 3. Expansion valve (or) device 4. Evaporator
  • 4.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 4 | 74 Compressor: The function of a compressor is to compress the fluid or gas and increase its pressure and temperature by some mechanical action done. Compressors are broadly classified as two types:  Positive Displacement Compressors  Dynamic Compressors Condenser: Condensation is a process of change of phase from gas form to liquid form, the same process happen inside a condenser. A condenser converts the refrigerant gas at high pressure & temperature into a liquid refrigerant at nearly high pressure & temperature by releasing the latent heat from the gas. Condensers are broadly classified as  Air Cooled  Water Cooled  Air and Water Cooled (or) Evaporative Condenser Expansion Device: The function of expansion device is to decrease the pressure & temperature of the liquid refrigerant by the process of expansion.
  • 5.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 5 | 74 Types of Expansion Devices:  Capillary Tubes  Thermostatic Expansion Valves  Electronic Expansion Valves Evaporator: Evaporation is a process of change of phase from liquid to gas form, the same process happens inside an evaporator. The evaporator converts the liquid refrigerant at low pressure & temperature into its gaseous form by absorbing the latent heat from the room air. Types of Evaporators:  Air Cooled  Water Cooled Refrigerants: Refrigerants are the heat transfer media used in the refrigeration cycle, which absorb heat from the room air during the process of evaporation at a region of low-pressure & temperature and releases the heat during the process of condensation at a region of high pressure & temperature. Ex: Air, Water, Refrigerants like R-12, R-22, R-134a, R-410a, NH3, LiBr3 (They have very low boiling point) Basic Refrigeration Cycle (In Detail) Principles of Refrigeration:  Liquids absorb heat when changed from liquid to gas.  Gases give off heat when changed from gas to liquid. Working of Refrigeration Cycle: 1. The refrigerant comes into the compressor as a low pressure gas, it is compressed and then moves out of the compressor as a high pressure gas. 2. The gas then flows to the condenser. Here the gas condenses to a liquid and gives off its heat to the outside air. 3. The liquid then moves to the expansion valve under high pressure. This valve restricts the flow of the fluid, and lowers its pressure as it leaves the expansion valve. 4. The low pressure liquid then moves to the evaporator, where heat from the inside air is absorbed and changes it from a liquid to a gas.
  • 6.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 6 | 74 5. As a hot low-pressure gas, the refrigerant moves to the compressor where the entire cycle is repeated. Components of Refrigeration Cycle: S.No. Name of Component Function 1 Compressor Increases the pressure and temperature of the gas by mechanical work done. 2 Condenser Change of phase from Gas to Liquid. Heat is rejected to atmosphere from the R-gas. 3 Expansion Device Decreases the pressure and temperature of the gas by expansion. 4 Evaporator Change of phase from Liquid to Gas. Heat is absorbed by R-gas from the indoor space. Compressor:  The purpose of the compressor is to circulate the refrigerant in to the system under pressure.  At the compressor, the low pressure gas is changed to high pressure gas.  The compressor has reed valves to control the entrance and exit of refrigerant gas during the pumping operation. Types of Compressors: 1. Positive Displacement a. Reciprocating – Single-Acting, Double-Acting, Diaphragm b. Rotary – Lobe, Liquid Ring, Screw, Scroll, Vane 2. Dynamic a. Centrifugal b. Axial Reciprocating Compressor:  A reciprocating compressor is also known as Piston Compressor.  The reciprocating compressor uses a piston, which moves inside a cylinder, to compress the air.
  • 7.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 7 | 74  When the piston moves down, air is drawn in. When the piston moves up, the air is compressed.  We have different types of reciprocating compressors: 1. Single-Acting Compressors:  These are usually reciprocating compressors which has piston working only in one direction.  The other end of the piston is open which does not perform any work.  The air is compressed only on the top part of the piston.  The bottom of the piston is open to crankcase and not utilized for the compression of air. 2. Double-Acting Compressors  These compressors are having two sets of suction and delivery valves on both sides of the piston.  As the piston moves up and down, both sides of the piston is utilized in compressing the air.  Thus both sides of the pistons are effectively used in compressing the air. 3. Diaphragm Compressors  Diaphragm Compressor is a kind of displacement compressors driven by electromotor.  Diaphragm Compressor contains two chambers in each cylinder body, i.e. 1. Hydraulic Oil Chamber 2. Gas Chamber Rotary Compressors:  They are different from the reciprocating compressors.  They does not have any pistons and crankshaft.  These compressors have Screws, Vanes, Scrolls and other devices which rotate and thus compress air.  The rotary compressors are classified into Screw type, Vane type, Lobe type, Scroll type and other types. Centrifugal Compressors:  The centrifugal air compressor which depends on transfer of energy from a rotating impeller to the air.
  • 8.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 8 | 74  Centrifugal compressors produce high-pressure discharge by converting angular momentum imparted by the rotating impeller (dynamic displacement).  Centrifugal compressors rotate at higher speeds than the other types of compressors. Axial Flow Compressors:  An Axial flow compressor is a pressure producing machine. It is a rotating based compressor in which the working fluid principally flows parallel to the axis of rotation.  A shaft derives a central drum, retained by bearings, which has a number of annular airfoil rows attached usually in pairs, one rotating and one stationary attached to a stationary tubular casing.  The rotating airfoils also known as blades or rotors, which accelerate the fluid. Condenser:  The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid.  Air passing over the condenser coils carries off the heat and the gas condenses.  The condenser often looks like an engine radiator.  Condensers used on R-12 and R-134a. Types of HVAC Condensers:  There are three types of HVAC condensers that depending on the cooling method that they used.  An HVAC condenser is an important part of your cooling system.  Condensers can either be 1. Water-cooled Condenser 2. Air-cooled Condenser 3. Air and Water-cooled Condenser (Evaporative type) Water-cooled Condenser:  A Water-cooled condenser works by moving water through the annular space between the tubes or coils.  Water acts as the cooling medium.  Water-cooled condensers require a constant supply of water to prevent corrosion.

    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 9 | 74  Types of Water-cooled Condensers: a. Double Pipe Condenser b. Double Tube Condenser c. Shell and Coil Condenser d. Shell and Tube Condenser Cooling Tower:  Cooling Towers are heat removal devices used to transfer waste heat to the atmosphere.  Cooling towers are required for recirculation of condenser water.  The warm water being pumped by the condenser should be cooled with the help of cooling towers, so that the same water may be re-circulated to the condenser.  Types of Cooling Towers: According to the method adopted to circulate the air, cooling towers may be classified as: a. Natural Draft Cooling Towers – The air is circulated inside the cooling tower by natural convection. The natural draft cooling towers are further classified as: Spray Type and Splash Deck Type. b. Mechanical Draft Cooling Towers:  The Mechanical Draft Cooling Towers are similar to Natural draft cooling towers, but the air is circulated inside the tower MECHANICALLY. Propeller fans or centrifugal fans may be used.  Mechanical draft cooling towers are much smaller than the natural draft cooling towers.  They are further classified as: a. Forced Draft Cooling Towers – A fan is located near the bottom and on the side. This fan forces the air from bottom to top. b. Induced Draft Cooling Towers – A fan is located at the top, takes suction from the tower and discharges it to the atmosphere. Air-cooled Condenser:  Cooling medium is ambient air.  It is used where there is of water scarcity.  Air-cooled condensers are designed for mostly residential applications and for small offices.
  • 10.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 10 | 74  An Air-cooled condenser is designed to move the air over the condenser coil using either a fan or at times a natural draft.  Finned coil-copper tubes & aluminum fins.  Refrigerant is inside the tubes.  Regular cleanings will greatly improve their efficiency and reduce wear and tear. Air and Water-Cooled Condenser (Evaporative Condenser):  Condensers that use a combination of air and water cooling are often referred to as evaporative condensers.  These are often used in large commercial cooling units.  In this condenser, water is sprayed from above onto the coils as air is blown from below.  This causes a cooling effect that condenses the refrigerant inside the coils.  Evaporative units generally do not waste water so they are a good choice in areas where water is scarce. Expansion Devices (or) Valves:  Expansion valve which expands the liquid refrigerant to lower its pressure and temperature before the refrigerant enters the evaporator.  It also regulates the flow of refrigerant in to the evaporator.  Expansion valves do not control humidity.  Expansion valves can be put into three categories: 1. Capillary Tube 2. Thermostatic Expansion Valve (TX valve) 3. Electronic Expansion Valve (EX valve) Evaporator:  The evaporator is a kind of heat transfer apparatuses where the heat transfer is done by forced convection or natural convection.  In the evaporator, a very large amount of heat is absorbed from surrounding (the indoor air) causing the liquid refrigerant to boil and turn into a gas phase.  The gas is passed to compressor to repeat the cycle again until the indoor air be comfortable and sufficiently cool.  Types of Evaporators:
  • 11.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 11 | 74 An Evaporator is used in an air-conditioning system to allow the refrigerant such as R-22 to evaporate from liquid to gas while absorbing heat in the process. In concept, an evaporator is similar to condenser, except an evaporation process occurs in an evaporator. 1. Shell and Tube Evaporator a. Shell and Tube with the Refrigerant Boiling in Shell b. Shell and Tube with the Refrigerant Boiling in Tubes 2. Plate Type Evaporator REFRIGERANTS:  ‘’Refrigerant is the fluid used for heat transfer in a refrigerating system that absorbs heat during evaporation from the region of low temperature and pressure, and releases heat during condensation at a region of higher temperature and pressure’’.  Example: Air, Water, Refrigerant gases like R-22, R-134a, R-410a etc.  HCFC-22 (or) R-22: Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22 or R-22. The boiling point of R-22 is -41.3o F (at atmospheric pressure 14.7 psia, 1 bar abs)  R-134A: 1, 1, 1, 2-Tetrafluoroethane, R-134a, Forane 134a, Genetron 134a, Suva 134a or HFC- 134a. It is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with less ozone depletion potential. It has the formula CH2FCF3 and boiling point of -26.3o C (-15.34o F) at atmospheric pressure.  R-410A: R-410A, sold under the trademarked names Forane 410A, Puron, Ecofluor R410, Genetron R410A, and AZ-20, is a zeotropic, but near-azeotropic mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane (CHF2CF3, called R-125), which is used as a refrigerant in air conditioning applications. The boiling point of R-410A is -55.4o F (at atmospheric pressure 14.7 psia, 1 bar abs)  NH3: Ammonia or ozone is a compound of nitrogen and hydrogen with the formula NH3.
  • 12.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 12 | 74 Ammonia as used commercially, is often called anhydrous ammonia, because NH3 boils at -33.34C C (-28.02o F) at a pressure of 1 atmosphere, the liquid must be stored under high pressure or at low pressure. Criteria for Refrigerant Selection: Some of the desirable characteristics for a widely used refrigerant include:  Environmental acceptability  Materials Compatibility  Chemical Stability  Refrigeration-cycle performance  Adherence to nonflammable and nontoxic guidelines  Boiling Point Classification of Air Conditioning Systems Based on the fluid media used in the thermal distribution system, air conditioning systems can be classified as: 1. All Air Systems 2. All Water Systems 3. Air-Water Systems 4. Unitary Refrigerant Based Systems All Air Systems: In this system, air is used as the media that transports energy from the conditioned space to the A/C plant. In these systems air is processed in the A/C plant and this processed air is then conveyed to the conditioned space through insulated ducts using blowers and fans. It is further classified into 2 sub-systems: 1. Single Duct System – It can provide either cooling or heating using the same duct, but not both heating / cooling simultaneously. 2. Dual Duct System All Water Systems: In this systems, the fluid used in thermal distribution system is water i.e. water transports energy between the conditioned space and the A/C plant. When cooling is required in the conditioned space then cold water is circulated between the plant & the conditioned space, while hot water is circulated through the distribution system when heating is required.
  • 13.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 13 | 74 It is further classified into 2 sub-systems: 1. 2 Pipe System – It is used either cooling or heating only application, but cannot be used for simultaneous cooling and heating. 2. 4 Pipe System – It consists of two supply pipelines – one for cold water and one for hot water, and two return water pipelines. Air-Water Systems: In this system, both air and water are used for providing required conditions in the conditioned space. The air and water are cooled or heated in a central plant. The air supplied to the conditioned space from the central plant is called as primary air, while the water supplied from the plant is called as secondary water. The complete system consists of a central plant for cooling or heating of water & air, ducting system with fans for conveying air, water pipelines and pumps for conveying water and a room terminal. The room terminal may be in the form of a FCU, an induction unit or a radiation panel. Unitary Refrigerant Systems: It consist of several separate air conditioning units with individual refrigeration systems. These systems are factory assembled and tested as per standard specifications and are available in the form of package units of varying capacity and type. Each package consists of a refrigeration and / or heating units with fans, filters, controls etc. Heat Load Calculation (or) Estimation Heat – it is a form of energy which can be neither created nor destroyed, but changes its form from one to another. Heat can be measured in terms of British Thermal Units (BTU). BTU – 1 BTU is an amount of heat required to raise the temperature of 1 pound of water by 1o F. TR – 1 TR is an amount of cooling given by 1 ton of ice kept in a room of dimensions 10’ x 10’ x 10’ in the next 24 hours. 1 TR = 12000 BTU 1 TR = 3.513 KW 1 TR = 3.41 BTU/hr Heat Load Calculation – It is a mathematical procedure of calculating or determining the amounts of heat which can get generated inside the building through internal & external sources of heat. This heat has to be removed from the building space to maintain a set of cooling conditions or in other words provide cooling to the room space to maintain the indoor conditions. This is measured in terms of TR (Tons of Refrigeration).
  • 14.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 14 | 74 Sources of Heat: 1. External Sources a. Sun – Wall, Glass, Roof, Partition b. Air – Ventilation, Infiltration 2. Internal Sources a. People b. Lighting (Watts) c. Equipment (KW) Purpose of Load Calculations: Load calculations can be used to accomplish one or more objectives: 1. Provide information for equipment selection and HVAC system design. 2. Provide data for evaluation of the optimum possibilities for load reduction. 3. Permit analysis of partial loads as required for system design, operation and control. These objectives can be obtained not only by making accurate load calculations but also by understanding the basis for the loads, where a brief description of cooling and heating loads is included. Building Survey Principles of Cooling Loads: In air-conditioning design there are three distinct but related heat flow rates, each of which varies with time. 1. Heat Gain or Loss 2. Cooling load or Heating load 3. Heat Extraction or Heat Addition Rate Heat Gain – It is the rate at which heat enters or is generated within a space at a given instant of time. There are two ways that heat gain is classified. They are the manner in which heat enters the space and the type of heat gain. The manner in which a load source enters a space is indicated as follows: 1. Solar radiation through transparent surfaces such as windows. 2. Heat conduction through exterior walls and roofs.
  • 15.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 15 | 74 3. Heat conduction through interior partitions ceilings and floors. 4. Heat generated within the space by occupants, lights, appliances, equipment and processes. 5. Load as a result of ventilation and infiltration of outside air. 6. Other miscellaneous heat gains. The types of heat gain are sensible and latent. Proper selection of cooling and humidifying equipment is made by determining whether the heat gain is sensible or latent. The sensible cooling load is defined as the rate at which heat must be removed from the space to maintain the room air temperature at a constant value. The actual total cooling load is generally less than the peak total instantaneous heat gain thus requiring smaller equipment than would be indicated by the heat gain. Heat extraction is the rate at which heat is removed from the conditioned space. Diversity of Cooling Loads: Diverting of cooling load results from not using part of the load on a design day. Therefore, diversity factors are the factors of usage and are applied to the refrigeration capacity of large air- conditioning systems. These factors vary with location, type, size of applicant based entirely on the judgement and experience of the engineer. Generally, diversity factors can be applied on loads from people and lights; there is neither 100% occupancy nor total lighting at the time of such other peak loads as peak solar and transmission loads. The reductions in cooling loads from non-use are real and should be accounted for. In addition to the factors for people and lights, a factor should also be applied to the machinery load in industrial buildings. It is advisable to measure the power input whenever possible as this will provide a diversity factor. It is also possible to determine a diversity factor for a large existing building by reviewing the maximum electrical demand and monthly energy consumption obtained from the utility bills. Principles and Procedures for Calculating Heating Load 1. Information Required (Inputs) – Before a cooling or heating load can be properly estimated a complete survey must be made of the physical data. The more exact the information that can be obtained about space characteristics, heat load sources, location of equipment and services, weather data, etc. the more accurate will be the load estimate. 2. Required Input – External Loads – Cooling: For calculation of the outdoor loads, the input information should include: a. Orientation and dimensions of building components.
  • 16.
    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 16 | 74 b. Construction materials for roofs, walls, ceiling, interior partitions, floors and fenestration. c. Size and use of space to be conditioned. d. Surrounding conditions, outdoors and in adjoining spaces. 3. Film Coefficient – In addition to the resistance of the various components of a barrier, we have to consider one more resistance offered by a film of air (or fluid if the barrier is a fluid) which clings on to the barrier surfaces. This resistance is more when the air is still and is relatively less when there is wind velocity. Outside Film Coefficient (RO) = 0.25 Inside Film Coefficient (RI) = 0.65 4. Storage Effect – Suppose “TO” is the temperature on both sides of the barrier. There will be no heat transmission through the barrier and the temperature at all points within the barrier will also be the same. Therefore, no temperature gradient. The walls take about 2 hours approximately to start conducting the heat onto the inside space. 5. Attic Spaces – Whenever a false ceiling is provided in a room, the space enclosed between the false ceiling and the concrete ceiling is called ATTIIC SPACE. If the attic space is not ventilated the entire space within the attic will assume an intermediate temperature which will be more than the room temperature and less than the outside temperature. Procedure for Heat Load Estimation  Collect architect drawings for the building giving all the details and dimensions of walls, floors, windows, etc. If such drawings are not available, survey the place and get the particulars.  For every applications, there are certain things which the ultimate user has to specify. These are: a. Temperature & humidity conditions to be maintained inside the space and tolerance. b. Occupancy – i.e., maximum no. of people likely to occupy the space and the nature of their activity. c. Lighting load and other internal source of heat generation. d. Period of operation – ex: 8 AM to 4 PM or 10 AM to 8 PM etc. e. For industrial application you require the HP load in the conditioned space and diversity factor thereon. f. Minimum ventilation required.

For comfort air conditioning application, use the mean maximum DB temperature & the WB temperature which occurs simultaneously with the assumed DB. 2. For industrial applications where temperatures and humidity are to be maintained within very close tolerance through the year, take the maximum DB and the simultaneously occurring WB temperature.  For all applications make a second load estimate for monsoon conditions.  For applications where the conditioned spaces are spread over very vast floor areas, divide the entire area into convenient zones and make load estimates.  Occupancy – In certain applications a diversity factor may have to be used even in respect of occupancy. Examples are: Office areas where a separate conference room is also provided. The conference room may be designed for a large number of people. But you must realize that it is mostly the people in the office who go into conferences and hence any occupancy in the conference room brings about an equal reduction in the occupancy in other areas of the office.  Typical Diversity Factors for Largest Buildings: Type of Application Diversity Factor for People Diversity Factor for Lights Office 0.75 to 0.90 0.70 to 0.85 Apartment, Hotel 0.40 to 0.60 0.30 to 0.50 Department Storage 0.80 to 0.90 0.90 to 1.0 Industrial 0.85 to 0.95 0.80 to 0.90 Design Conditions of the Project Outside Design Conditions: Outside design condition is a combination of the temperature and the relative humidity of the external environment with respect to the building structure. Outside Conditions: Temperature = 106 O F (41 O C) Relative Humidity = 28% Tc = (5/9)*(Tf-32) Where, Tc = Temperature in degree Celsius

Co-ordination with other Services – Electrical (Lighting, Equipment) Modes of Heat Transfer There are three modes of heat transfer: a. Conduction: It is the transfer of heat from one part of a substance to another in physical contact with it, without appreciable displacement of molecules forming the substance. Conduction takes place in solids, liquids and gases. b. Convection: It is the transfer of heat within a fluid by mixing of one portion of fluid with another, there is an appreciable movement of the molecules of the fluid. Natural convection takes place due to density difference. Forced convection takes place by doing work (blowers, pumps, etc.) Convection takes place in gases and liquids. c. Radiation: It is the transfer of heat in space in form of electro-magnetic waves or quanta. Radiation does not need medium it can pass thru vacuum. Psychrometry: The area of measuring the moisture content of air is termed as Psychrometry. Psychometrics: It is a science involving the study of air and the moisture present in the air (properties of air) with consideration to the human comfort conditions.

Return Air Diffuser Supply Air: It is defined as the conditioned air being supplied from the air conditioner outlet. The air is treated air & contains all the desired qualities as provided by the air. Return Air: It is defined as the air being supplied back to the air conditioner from the air conditioned space. This air is returned back to the air conditioner after being circulated in the conditioned space. Fresh Air: It is defined as the ambient air being supplied to the air conditioner inlet from the outside atmosphere. This air is supplied to the air conditioner inlet from the outside atmosphere after being initially treated. Types of Pressure 1. Total Pressure 2. Static Pressure 3. Velocity Pressure Total Pressure = Static Pressure + Velocity Pressure  Static pressure is measured perpendicular to the direction of flow of the air. It may be positive or negative.  Velocity pressure: The pressure due to velocity of the air flowing in a duct is termed as velocity pressure. It is always positive and always exerted in the direction of flow. Velocity Pressure = Total Pressure – Static Pressure Aspect Ratio: Aspect Ratio = Long Side of Duct / Short Side of Duct (Or) = Width of the Duct / Height of the Duct Best Aspect Ratio is 1:1 Maximum permissible Aspect Ratio is 4:1  In Rectangular ducts the best aspect ratio is 1:1 i.e. 1. As the Aspect ratio increases the friction per running feet of the duct increases due to increase in surface area.

Duct Leakage Test: - Air Pressure Test - Smoke Test - Light Test Pipe Leakage Test: - Hydro Test Testing, Adjusting & Balancing (TAB) is done as per final handover requirements. Testing, Adjusting & Balancing (TAB) operation: The phrase testing, adjusting and balancing (TAB) has become popular. As a description of what is commonly called balancing. Testing is the process of operation & checking the performance of equipment. Balancing is the process of proportioning the correct flow of air & water throughout the system. Such as through mains, branches, equipment & terminal units. Adjusting is the process of regulating & setting the variable so that a balance system is achieved. The variable may be speed, temperature, pressure, flow rate, etc. Some devices that control a variable for example, a valve may be regulated to adjust flow rate in the process of balancing. Instrumentation: The success of the TAB operation depend on accurate instrumentation. These instrument are used for measuring temperature, pressure, velocity, flow rates, speed, heat flow & electrical energy. Instrument have varied degree of accuracy. For TAB work as accuracy within 5% of the true value is more than sufficient and is usually available in the market. Instrument should be always calibrated before each use. Measurement of Temperature: Thermometer with an accuracy of + (or) – 0.5o C or + (or) – 1o C are suitable for HVAC work. Measurement of Pressure:

    MOHAMMED ABDUL RAZZAKHVAC CLASS NOTES P a g e 72 | 74 Manometer are simple and accurate pressure measuring instrument which utilize the pressure that will lift a column of liquid. Water or mercury are the two common liquid used. The U-Tube Manometer is the simplest arrangement. One end of the manometer is connected to the location where pressure is to be measured, and other is usually open to the atmosphere. The reading on the manometer is therefore gauge pressure. Bourdon Pressure Gauge: It is a most commonly used type for installation in pipeline & in vessels. This type of gauge is rugged & reliable and relatively in-expensive. It is not suitable for reading very small pressure differences. Measurement of Velocity: For very approximate air velocity steady smoke can be use. The smoke generated by a mechanical device or candles (smoke emitters) is injected in the air stream and absorb more practical use of smoke is to examine the air distribution pattern in a room & to find air leakages in ducts. Silicon sealant is used to close the duct leakage. Anemometer & Pilot Tube are most frequently used for measuring air velocities.
