Refrigerating Compressor. Refrigerating Compressor. a compressor that is a component of a vapor-compression refrigerating machine and is used to draw the refrigerant vapor from the evaporator and deliver it to the condenser.
The purpose of the compressor is to circulate the refrigerant in the system under pressure, this concentrates the heat it contains.
