What is Air-Conditioning?
Air- conditioning is the process of obtaining the desired air property or a condition like a temperature, humidity, purity, pressure.
Used in Domestic as well as in the commercial environment.
Definition: – Air –conditioning is the simultaneous control of temperature, Relative Humidity, Air movement, and Air cleanliness in the conditioned space.
The primary function of air conditioning is to maintain conditions that are: 1)For Human Comfort 2) Required by a product or process within space. ●
Reasons for using Air conditioning:-
a) To improve productivity in the office, factories by maintaining comfort conditions for people.

How Does Air-Conditioning Works?
As with all air conditioning systems, the principle remains the same whereby the heat is removed from one area and replaced with chilled dry air and the hot air is expelled, normally to the outside atmosphere.
An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil. The fan, located in the outside unit, blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air.
Most air conditioning systems have five mechanical components:
• a compressor
• a condenser
• an evaporator coil
• a chemical refrigerant
