The basic principle of operation of the Refrigerated Air Drier
is the removal of moisture by cooling air to certain present temperature.
There is no process known for producing cold, there is only heat
removal. Heat is always attracted by the cold body. This is the
basis for the operation of a cooling unit. As long as the temperature
of the cold body is lower than the hot source, there will be heat
transfer.
The air entering the system enters into the precooler. A precooler
is a heat exchanger where the incoming hot air is being cooled by
the outgoing cold air so as to reduce the heat load for the evaporator
and thereby the refrigeration system. The air from the precooler
enter into the evaporator. In evaporator the cooling, heat removal
is done by the boiling refrigerant. The air with condensate, enters
into moisture separator, where the moisture is removed by the centrifugal
action of air. The air free from moisture enters the precooler to
cool the incoming air and thereby some heat is added.
The refrigerant circuit consists of a Compressor, a Condensor,
a Filter Dryer, an Expansion Valve or a Capillary Tube and an Evaporator.
