REFRIGERANT DRYERS OPERATOR’S MANUAL TM357-035 & TM357-074
2.2 WORKING PRINCIPLE
The gaseous refrigerant coming from the evaporator (4) is sucked by the refrigerant
compressor (1) and it is pumped into the condenser (2). This one allows its condensation,
eventually with the help of the fan (3); the condensed refrigerant passes through the
dewatering filter (8) and it expands through the capillary tube (7) and goes back to the
evaporator where it produces the refrigerating effect. Due to the heat exchange with the
compressed air which passes through the evaporator against the stream, the refrigerant
evaporates and goes back to the compressor for a new cycle.
