What is the process of evaporation?
Evaporation is an endothermic process , which means it draws heat from the surroundings. For this evaporation to happen, the refrigerant has to be pressurized in its liquid form so it will evaporate when it passes through a tiny aperture in the coil system.
How does a compressor work?
The job of the compressor is to create and maintain this pressure. It's common for compressors to work by reciprocating action. A piston cycles back and forth, pumping refrigerant into the coil on the forward stroke, and a valve prevents the refrigerant from flowing backwards when the piston retracts.
