TECHNICAL PRINCIPLES OF OPERATION. The purpose of the sink is to provide a temperature-controlled
medium for use in tray processing. It also contains a refrigerated storage cabinet for photographic chemistry. It consists
of:
Refrigeration System
Recirculating System
Heating System
Electrical System
5-3.1.
Refrigeration System. Removes heat from recirculating water and storage cabinet.
a.
Compressor. Compresses freon gas for refrigeration process. It is a sealed, single-piston unit driven by an
electric motor.
b.
Condenser. Contains the compressed liquid refrigerant. After exiting the compressor unit, the compressed
refrigerant gives up heat through the air-cooled condenser coils.
c.
Liquid receiver. Acts as a storage tank and contains approximately one pound of liquid refrigerant in excess of
actual requirements.
