Refrigeration and air conditioning systems use a refrigeration cycle to remove heat from an enclosed space and lower its temperature. The refrigeration cycle involves compressing a refrigerant vapor, condensing it into a liquid, expanding the liquid to produce cooling, and evaporating the liquid to remove heat. Common applications of refrigeration include cooling food in refrigerators and preserving temperature-sensitive substances like vaccines or hormones. Proper heating, ventilation, and air conditioning systems are also important for manufacturing pharmaceuticals by maintaining environmental conditions, preventing contamination, and protecting personnel comfort and health.
“Refrigerant is the media (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.”

ENERGY AUDIT presentationin power system .pptxReshevSharma
An energy audit is a systematic process of evaluating and analyzing energy usage in a building, facility, or industrial process to identify opportunities for energy efficiency improvements, cost savings, and environmental sustainability. The goal of an energy audit is to assess energy consumption patterns, identify areas of inefficiency or waste, and recommend measures to optimize energy usage and reduce overall energy consumption.
Here's an overview of the typical steps involved in conducting an energy audit:
1. **Pre-Audit Planning:**
Define the scope and objectives of the energy audit, including the areas or systems to be evaluated, the level of detail required, and the desired outcomes. Identify key stakeholders, establish audit goals, and gather relevant documentation, such as utility bills, building plans, and equipment specifications.
2. **Data Collection and Analysis:**
Collect comprehensive data on energy consumption, including utility bills, meter readings, and operational data

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. *The process of keeping an item below
room temperature by storing the item
in a system or substance designed to
cool or freeze is Known as
Refigeration. The
most common form of refrigeration is
provided by systems (i.e.
refrigerators) that use
a refrigerant chemical to remove heat
from items stored inside the system.
4. *The Cycle operates at two pressures,High and Low,to
enable the process to produce a continuos cooling
effect.The sequence of events in the Refrigeration cycle
can be explained as:
(a)Receiver or Condenser
*The Liquid refrigerant is kept in a container called
condenser. The refrigerant is under pressure and the
vapour and liquid phases are in equilibrium.
(b)Expansion Valve
It is a device, which controls the rate of flow of refrigerant
into the evaporator, converting the refrigerant from high
pressure to low pressure. The refrigerant enters a low-
pressure zone.
5. *(c) Evaporator: Subsequently a mixture of
vapour and liquid enters the evaporator,
which consists of coils. Here the refrigerant
by absorbing heat from the space, the
molecules move apart by breaking
intermolecular forces. The energy(heat)
required for this process is taken from the
surrounding environment, i.e space, which
is to be cooled. In this step, Liquid
vaporises completely , though some liquid
still remains.
6. *(d) Liquid Trap : A liquid trap is used to remove liquid, which is
then returned to receiver (condenser).
*(e)Compressor : The saturated vapour is allowed to pass through
the compressor .During compression, heat of compression is
added to vapour and the pressure raises. The compression is
adiabatic and on the discharge side it produces a supersaturated
gas. The valve should be opened very slowly. A part of the liquid
vaporises to give a stream of high velocity.
(f)Condenser: The supersaturated vapour flows to the condenser
where the gas is liquified. These condensers can be air-cooled or
water-cooled.
Thus,one cycle is completed as shown in the figure and the
process continues.
7. *Applications
-Removal of heat from chemical
reactions.
-Preservation of
thermolabile
substances. Eg:
insulin,ACTH,pituitary hormones and
vaccines.
8. *- Liquify Processing gas
*-separation of vapour by
distillation
*-purification of products
*-preferential freeze-out of one
component from a liquid mixture.
9. *
*Process of treating air so as to control simultaneously its
temperature, humidity, cleanliness and distribution to
meet the requirements of the conditioned space.
*Applications
*Promotion of human comfort
*Maintenance of proper conditions for the manufacture,
processing and preservation of materials and
equipments
*Ensure efficiency and health of the workers at
reasonably satisfactory levels

11. *
*Also called unitary or packaged equipment.
*Classified as room air conditioners, residential units and
commercial or industrial units.
*Contains a complete cooling system in one pack containing
a compressor, condenser, evaporator, fan, filter and
controls.
*A heating coil may also be added and a humidifier may be
added to provide winter humidification.
12. *Window Air Conditioner
* Most commonly type for single rooms
* All the components (compressor, condenser, expansion
valve or coil, evaporator and cooling coil) in a single box.
* Fitted in a slot made in the wall of the room, or often a
window sill.
13. *Split Air Conditioner
* Comprises of two parts: the outdoor unit and the
indoor unit.
* Outdoor unit, fitted outside the room, houses
components like the compressor, condenser and
expansion valve.
* Indoor unit comprises the evaporator or cooling
coil and the cooling fan.
* Used to cool one or two rooms.
14. *
* Used to cool more than two rooms or a larger space at your home or
office.
* Two possible arrangements with the package unit.
* First arrangement: All the components, namely the compressor,
condenser (which can be air cooled or water cooled), expansion valve
and evaporator are housed in a single box. The cooled air is thrown by
the high capacity blower, and it flows through the ducts laid through
various rooms.
* Second arrangement: Compressor and condenser are housed in one
casing. The compressed gas passes through individual units, comprised of
the expansion valve and cooling coil, located in various rooms.
15. *
* Provide conditioned air to one or more areas through duct systems.
* Water or direct expansion refrigerated coils or air washers used for cooling
* Steam or hot water coils for heating
* Humidification by surface type water nozzles, steam humidifiers or sprayed coils.
* Air cleaning by filters that can be cleaned or throw away type.
16. *
*Heating, ventilation and air-conditioning (HVAC) play an
important role in ensuring the manufacture of quality
pharmaceutical products.
*A well designed HVAC system will also provide comfortable
conditions for operators.
