THE REFRIGERATION CYCLE

The compressor discharges high pressure, high temperature gas into the back panel condenser circuit first,
returning via the oil cooler in the compressor and entering the 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 (viewed from the rear of
the cabinet).
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 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.
