Introduction
The purpose of the compressor in a refrigeration system is to raise the pressure
of the refrigerant vapor from evaporator pressure to condensing pressure. It
delivers the refrigerant vapor to the condenser at a pressure and temperature at
which the condensing process can be readily accomplished, at the temperature
of the air or other fluid used for condensing.
A review of the refrigeration cycle, using the pressure–enthalpy chart, will help
to illustrate this point.
