IDF190D Compressed Air and refrigerant circuits 

IDF240D Compressed Air and refrigerant circuits 

Air circuit 

The humid hot air that enters the air dryer first goes into the reheater, and exchanges its heat with 
dehumidified cold air to pre-cool it. Then, the air enters the evaporator, where it releases its heat to 
a cold HFC, and is dehumidified and cooled further to let moisture separate. Finally, the air 
exchanges heat with the hot air coming to the air dryer and its temperature increases higher, and it 
leaved the air dryer as warm, dry air. 

 

Refrigerant circuit 

The fluorocarbon gas (HFC) in the refrigerant circuit is compressed by the compressor and cooled 
by the condenser to become liquid. When passing through the capillary tube, the HFC gas is 
regulated and its temperature decreases. While passing through the cooler part, it evaporates 
rapidly, taking the heat from the compressed air, and is sucked in by the compressor. The volume 
control valve opens when the compressed air has been cooled sufficiently, and prevents 
condensed water from being frozen by excessive cooling.
