SEALED SYSTEM OPERATION

The following six diagrams represent the basic model
315W sealed system. The components are listed in
order of refrigerant flow, with an explanation of their fun-
damental role as part of a sealed system.
Compressor (Figure 4-1)
The compressor creates a high and low side pressure
difference in the sealed system. When the compressor
piston pushes, compressing the refrigerant gas, it caus-
ing the refrigerant pressure and temperature to rise.
The high-pressure/high-heat refrigerant gas is pushed COMPRESSOR
out the compressor discharge tube to the condenser.
Figure 4-1. Compressor
Condenser (Figure 4-2)
The high-pressure/high-heat gas travels through the
condenser tubing, where most of the heat in the refrig-
erant is drawn out and dissipated into the room by the
cooler ambient air that is being drawn over the con-
denser tubing (referred to as heat transfer). This
changes the gas into a high-pressure warm liquid
before it enters the high-side filter-drier.
CONDENSER
Filter-Drier (Figure 4-3)
The high-pressure warm liquid travels through the high-
side filter-drier, where the desiccant pellets inside the
drier remove moisture from the refrigerant before it
enters the capillary tube.
