REFRIGERATION SYSTEM
Component Description
COMPRESSOR:
The compressor is a factory sealed unit located
underneath (outside) the cooling cabinet. This
pump is activated by a motor which draws low
pressure vapor (refrigerant) from the evaporator.
It then compresses the gas and forces it into the
condenser at a high pressure.
STARTER RELAY:
The starter relay is attached on one side of the
compressor box. The compressor motor has two
windings: one for starting and another for running.
In order to provide for the necessary additional
torque when the motor is rst ignited, the starter
relay connects the additional start-up windings. Af-
ter the motor reaches its correct operating speed,
the relay opens the ignition windings and the motor
carries on with the operation windings.
THERMAL PROTECTOR:
This protector is a thermo-sensible device attached
to one side of the compressor’s box. In any given
situation, if the compressor overheats or if the
voltage source varies drastically, the thermal
protector opens, turning o󰀨 the compressor. After
the compressor cools down to a normal and safe
working temperature, the thermal protector turns
on the compressor.
CONDENSER:
The condenser is located underneath (outside)
the cooling cabinet in front of the compressor. Its
receives hot, high pressure refrigerant gas from
the compressor, and cools it down until it returns
to liquid state.
CONDENSER FAN MOTOR:
The condenser fan motor is located underneath
the cooling cabinet. It is a ventilation device which
forces the ambient air to ow over the condenser in
order to cool down the refrigerant owing inside it.
The fan motor works only if the compressor is on.
