Compressed Air Circuit
Humid hot air entering air dryer is cooled in
the cooler. At this time, the condensed
moisture is separated from the air by the
drain separator and automatically
discharged.The dried clean air is heated by
the reheater untill it gets about the same
temperature as that of ambient air. It is then
discharged from air dryer outlet.
Refrigerant Circuit
The Fluorocarbon charged in the
refrigerant circuit is compressed by the
compressor and cooled by the condenser
to become liquid. Then, going through the
capillary tube, it is decreased the pressure
to reach a low temperature.
Passing
through the cooler part, it draws heat from
compressed air and intensely boils. Finally
it is inhaled into the compressor again. The
capacity control valve opens to prevent
dew drops from freezing when
compressed air is cooled enough.
