Function of the main components

Functional diagram
As the refrigerant circulates through the unit, changes in its state or
condition occur. These changes are caused by the following main
components:
■
Compressor
The compressor (M*C) acts as a pump and circulates the
refrigerant in the refrigeration circuit. It compresses the refri-
gerant vapour coming from the evaporator to a pressure at
which it can easily be liquified in the condenser.
■
Condenser
The function of the condenser is to change the state of the
refrigerant from gaseous to liquid. The heat gained by the gas in
the evaporator is discharged through the condenser and the
vapour condenses to liquid.
■
Filter
The filter installed behind the condenser removes small particles
from the refrigerant to prevent blockage of the tubes.
■
Expansion valve
The liquid refrigerant coming from the condenser enters the
evaporator via an expansion valve. The expansion valve brings
the liquid refrigerant to a pressure at which it can easily be
evaporated in the evaporator.
■
Evaporator
The main function of the evaporator is to take heat from the
water that flows through it. This is done by turning the liquid
refrigerant, coming from the condenser, into gaseous
refrigerant.
■
Water inlet/outlet connection
The water inlet and outlet connections allow an easy connection
of the unit to the water circuit of the air handling unit or industrial
equipment.
