Refrigerant Flow
The compressor compresses R134a refrigerant,
raising its pressure and temperature. Refrigerant
vapor is pumped out the compressor discharge,
down through the drain pan loop, up through
the condenser coil, around the condenser loop,
through the drier, and into the 3-way valve. By
the time the refrigerant has reached the 3-way
valve, it has completely condensed into a liquid.
Depending upon whether the main control board
opens the 3-way valve to the freezer evaporator
or the fresh food and freezer evaporators,
refrigerant fl ows through the appropriate capillary
tube and into the evaporator. 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, becoming cold. At the outlet of the
freezer evaporator, an accumulator captures any
remaining liquid, allowing only low pressure vapor
to return to the compressor through the suction
line.
