How Air Conditioning Works?
Air conditioning like it says ‘conditions’ the air. It not only cools the air, but also reduces the moisture content, or humidity.The principles of evaporation and condensation are utilized in your car’s A/C system by a series of components that are connected by tubing and hoses.
There are six basic components: the compressor, condenser, receiver-drier, thermostatic expansion valve, the evaporator and gas in the A/C system which is the refrigerant.

A number of people don’t realize that turning on the air conditioning actually reduces the number of klms you can travel per full tank of your car. There is energy used in removing the heat and moisture from the air in the car, and this consumes petrol because of the extra engine load.
Refrigerant is a liquid capable of vaporizing at a low temperature. In the past, R-12 refrigerant was used in cars. But this chlorofluorocarbon (CFC) is harmful to the earth’s ozone layer. Consequently, all vehicles built after 1996 use R-134A, a more environmentally friendly refrigerant.
