All air conditioners, regardless it has been an auto AC, home HVAC or household refrigerator, have been known to work on similar principles. A liquid refrigerant has been changed to gas and then back to liquid. In case, a change-of-state of the refrigerant has to take place, heat transfer should take place. The other rules that apply to refrigerant have been, foremost, refrigerant in a gaseous state collects, holds and absorbs heat and secondly, the refrigerant in a liquid state releasing the heat.

Operation and components of AC

For your auto AC to blow cold air, a refrigerant should pass through and change state in three components, foremost being receiver-dryer, and one expansion valve, which would make up the closed auto air conditioning system. The components of the system have been as follows.

Compressor

A device pressurizes the heated refrigerant.

Condenser

A radiator for refrigerant would transfer the heat that might be absorbed in the passenger compartment to the cooler air.

Evaporator

It is a small radiator located under dash in the passenger compartment. The liquid refrigerant entering the evaporator would create a pressure loss. The liquid refrigerant would absorb heat from the air blowing that blows across the evaporator. It would then boil and changes state to vapour prior to it entering the suction port of the compressor.

Receiver-Dryer

It is a canister storing the liquid refrigerant when the compressor is not running. It would comprise a desiccant that would remove moisture from the system.

Expansion Valve

It has been a metering device to control the amount of refrigerant to the evaporator.
