8.5  Air/ Refrigerant Circuit 

 
 
 

 

- 

Compressed Air Circuit 

The heat of humid hot air entering to the air drier enters to the cooler and is cooled and dehumidified 
by cold fleon, separating the moisture. 
The cold air is released from the air dryer. 

 

- 

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.
