Compressed Air and Refrigerant Circuit/Option Principles
Compre sse d Air Cir cuit
Humid hot air entering air dryer is cooled in the cooler. At this time, the condensate is separated from
the air by the drain separator and automatically discharged. The dry air is heated by the re-heater until
it gets about the same temperature as that of ambient air. It is then discharged from air dryer outlet.
Refriger ant Circ uit
The freon gas charged in the refrigerant circuit is compressed by the compressor and cooled by the
condenser to become liquid. Then, going through the capillary tube, the refrigerant pressure and
temperature (evaporating temperature) decreased rapidly. Passing through the cooler part, it draws
heat from the hot compressed air and intensely boils. Finally, it is sucked into the compressor again.
The Capacity control valve opens to prevent compressor from freezing when compressed air is too
cold.
