M. FAN MOTOR (Air cooled version)
The fan motor is controlled through the TRIAC of
the P.C. BOARD by the condenser temperature
sensor. Normally it operates to draw cooling air
through the condenser fins.
In cold ambient situation, the fan motor can run
at intermittance as the condenser pressure must
be kept between two corresponding head
pressure values.
N. WATER REGULATING VALVE
(Water cooled version)
This valve controls the head pressure in the
refrigerant system by regulating the flow of water
going to the condenser.
As pressure increases, the water regulating
valve opens to increase the flow of cooling
water.
O. COMPRESSOR
The hermetic compressor is the heart of the
refrigerant system and it is used to circulate and
retrieve the refrigerant throughout the entire
system.
It compresses the low pressure refrigerant vapor
causing its temperature to rise and become high
pressure hot vapor which is then released through
the discharge valve.
