Refrigeration System
The compressor compresses R134a refrigerant, raising its pressure and temperature. Refrigerant
vapor is pumped out the compressor discharge, through the condenser, around the hot gas loop,
through the drier, and into the evaporator. By the time the refrigerant has reached the evaporator, it
has completely condensed into a liquid. As the high pressure liquid passes through the capillary
and enters the low pressure evaporator, it quickly expands and evaporates. During evaporation, the
refrigerant absorbs heat through the evaporator. At the outlet of the freezer evaporator, low pressure
vapor returns to the compressor through the suction line.
