This document provides an overview of air conditioning, including its main components and types. It discusses that air conditioning controls various parameters of air like temperature, moisture, and purity. It then describes the main types of air conditioning based on application, including comfort, industrial, summer-only, winter-only, and year-round. The main parts of window and split air conditioners are also outlined, such as the compressor, condenser, evaporator, and thermostat. Filters and control panels are also discussed.

2. Introduction to air
conditioning.
 Refrigeration deals mainly with temperature control,
but air conditioning is a science which focuses on
various parameters of air such as temperature,
moisture content, etc.
 It is mainly used for producing controlled
atmosphere.
 Air conditioning can be defined as a process of
conditioning air by controlling its temperature,
moisture, purity and distribution.

3. Types of Air Conditioning
 They are classified according to their application:-
• Comfort air conditioning.
• Industrial air conditioning.
• Summer air conditioning.
• Winter air conditioning.
• Year round air conditioning.

4.  Comfort air conditioning:- it is designed to
produce comfort zone for human beings. It is used
in offices, homes, theaters, etc.
 Industrial air conditioning:- it is designed to
produce control atmosphere according to
processes carried at particular industry. Industries
like textile or paper requires very high moisture
content.
 Summer air conditioning:- according to usage in
the season it is said as summer air conditioning
when it can be used only during summer season.

5.  Winter air conditioning:- it will provide
comfortable space for winter. Its function is to
increase temperature and moisture content of
atmospheric air and supply it to a particular space.
 Year round air conditioning:-It can be used in
every season of the year. It can provide
comfortable air to the space irrespective of the
summer, winter or monsoon season.

6. MAIN PARTS OF
WINDOW
AIR- CONDITIONER
• Compressor
• Condenser
• Metering device
• Evaporator
• Fan and motor
• Filter

CONDITIONER

8. COMPRESSOR
 The compressor is the heart
of the cooling cycle. The
cycle begins when the
compressor draws in cool,
low-pressure refrigerant gas
from the indoors. The motor-
driven compressor’s sole
function is to "squeeze" the
refrigerant, raising its
temperature and pressure so
that it exits the compressor
as a hot, high-pressure gas.

9. CONDENSER
 This component receives
gas at high pressure and
high temperature from the
compressor. In air-cooled
condensers, the metallic
surfaces cool the gas which
changes status and turns to
liquid. In the case of water-
cooled condensers, it is the
circulation of the water that
produces the same cooling
effect

10. CAPILLARY TUBE
 A narrowing of the tube
connected along the line
between the condenser
and the evaporator with
diameters ranging from 1
to 2 mm. and lengths
ranging between 1 and 2
m, allows the adjustment
of the amount of gas fed to
the evaporator.

11. EVAPORATOR
 When the refrigerant evaporates in the evaporator,
it absorbs heat from the surrounding air and
produces cooled air.

12. THERMOSTAT
 Another important element is the thermostat. This
allows you to choose how cool you want your
house. Setting it at a higher temperature will save
you more money than setting it at a very low
temperature. Be sure your thermostat also shows
you the indoor temperature. This will help you
asses any possible problems. You will know if it is
taking to long for your house to cool down, if it
becomes to cool or if it doesn’t become cool
enough.

13. AIR FILTERS
 Without filters, outdoor allergens can easily
pollute your home. This will cause added
stress to any allergy sufferers. Filters also
help reduce a home’s humidity, reducing
the viability of any mold spores, making
your home healthier. All the filters should
be changed periodically. They also need to
be cleaned. This prevents dust from
collecting on the evaporator coil and
encourages more energy consumption.

14. CONTROL PANEL
 Control Panel is used to control the temperature
and speed of the blower fan. A thermostat is used
to sense the return air temperature and another
one to monitor the temperature of the coil. Type of
control can be mechanical or electronic type
CONDENSER FAN
 The condenser fan is the forced draft type of
propeller fan that sucks the atmospheric air and
blows it over the condenser. The hot refrigerant
inside the condenser gives up the heat to the
atmospheric air and its temperature reduces.

15. MAIN PARTS OF SPLIT AIR-
CONDITIONER
 It is mainly divided into two parts:-
• Outdoor section
• Indoor section

16. SPLIT AIR-CONDITIONER

17. OUTDOOR SECTION
 It consist of two parts:-
• Compressor
• Condenser
INDOOR SECTION
 It consist of two parts:-
• Expansion valve
• Evaporator

18. OUTDOOR SECTION
 COMPRESSOR:
The compressor is a big electric pump that works
with the condenser to turn the refrigerant back to
liquid. It does this by pressurizing the refrigerant
gas. The compressor is also located in the hot side
of the air conditioner with the condenser.
 CONDENSER :-
The condenser is the counterpart to the evaporator
and is located in the hot side of the air conditioner. It
functions to bring that hot, condensed refrigerant gas
back outside to vent the heat and turn the refrigerant
back into a liquid form

19.  EXPANSION VALVE:-
The expansion valve works with the evaporator, but
is usually located in-between the evaporator and
condenser. Its job is to regulate how much liquid
refrigerant is moving into the evaporator, where it
then changes into gas.
 EVAPORATOR:-
The evaporator is located in the cold side of the
air conditioner. Its main function is to receive
liquid refrigerant and turn it into gas, which then
cools and dehumidifies the air. The gas absorbs
all of the heat from the air and takes it to the
condenser.
