Figure 1. The refrigeration system. In a typical refrig-. eration system, the compressor sends hot gas to the. condenser. Then the condensed liquid passes through. an expansion valve into the evaporator where it evap-. orates and collects heat from the area to be cooled. The gaseous refrigerant then enters the compressor. where the compression process raises the pressure. and temperature. From the compressor, the refrigerant.
