Description of its components
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 necessary additional torque
when the motor is first ignited, the starter relay connects the additional start-up windings. After 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 the voltage source varies drastically, the thermal protector
opens, turning off 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. It receives
hot, high-pressure refrigerant gas from the compressor and cools it down until it returns to liquid state.
