Simple Explanation of Air Conditioning Process

 Air Conditioning process can divide in to four sections such as Compressor, Condenser, Expansion Valve and Evaporator.This process is cycle and it can discrbe as simple as following image.There is a high preasuer and low pressure side of the air condition and blue color show the cooling side and red color show the heated high pressure sides. 
Air condition cycle
Compressor
 The compressor which pumps the refrigerant around the system is the heart of the air conditioner. Before the compressor, the refrigerant is a gas at low pressure. Because of the compressor, the gas becomes high pressure, gets heated and flows towards the condenser.

Condenser
At the condenser, the high temperature, high pressure gas releases its heat to the outdoor air and becomes sub cooled high pressure liquid.

Expansion Valve
The high pressure liquid goes through the expansion valve, which reduces the pressure, and thus temperature goes below the temperature of the refrigerated space. This results in cold, low pressure refrigerant liquid.

Evaporator
The low pressure refrigerant flows to the evaporator where it absorbs heat from the indoor air thought evaporation and becomes low pressure gas. The gas flows back to the compressor where the cycle starts all over again.
