5.3 The Refrigeration Circuit
The compressor discharges high pressure, high temperature gas into the back panel condenser circuit first,
and then into the right hand side condenser in the cabinet by way of the base tube. This tube runs from the
compressor compartment forward to the front bottom edge of the cabinet, returning down the left hand side
to be connected to the left hand side condenser coil.
A loop from this condenser coil forms the cross rail mullion on dual temperature cabinets. The condenser
then continues across the top front edge of the cabinet to form the right hand side condenser before entering
the filter drier which is mounted vertically in the unit compartment.
Now the high pressure gas has been condensed, the liquid refrigerant flows through the capillary tube,
entering the evaporator mounted in the freezer compartment. The liquid refrigerant then boils off due to the
low suction pressure applied to within the evaporator from the compressor. The heat laden vapour is drawn
back to the compressor by way of the suction line to start the cycle all over again.
The above information relates to the cabinet, not the drawing below.
