1.
COMPRESSOR AND MOTOR ASSEMBLY
The compressor and motor assembly is located in the
machine compartment of the water cooler. The
assembly is suspended on springs, inside an all welded
steel housing and is lubricated by a wax-free dehydrated
oil. The compressor assembly is provided with an
external electrical terminal enclosure, located on the side
of the housing.
The electrical terminal enclosure has a high
impact, fire resistant cover. The relay and overload are
mounted in this enclosure.
When supplied, the relay operates in the starting
of the compressor motor and disconnects the starting
winding when the motor reaches its proper speed
The overload protector, retained against the
compressor housing, is of the automatic reset type and
breaks the circuit within a few seconds if the compressor
fails to start. The circuit will also be interrupted if the
compressor overheats during operation.
'When required a capacitor is used on some water
coolers to increase the starting torque of the compressor
motor and/or aid its operation.
2.
CONDENSER
As the refrigerant passes through the condenser, heat is
removed, causing the refrigerant to cool and condense
to a high pressure liquid. The principle means of
removing heat is by natural or forced convection air or
water.

Air-Cooled Condenser - The static condenser
depends upon its large exposed surface area and
natural convection air in a favorable
