  • Page 14 4. Refrigeration air dryer operation The refrigeration air dryer is designed to remove moisture from the input air to achieve the desired dew point at the exit. All refrigeration air dryers described above operate according to the same principle. The operation of the refrigeration air dryer can be divided into two main circuits: Air and refrigeration circuit.
  • Page 15 5. Refrigeration air dryer components 5.1. Compressor with frequency converter The compressor sucks the gaseous phase of the refrigerant from the evaporator (low pressure side) and compresses it to the condensation pressure (high pressure side). Built-in compressors are manufactured by leading manufacturers and are designed for applications where high compression ratios and high temperature differences are present.
  • Page 16 maximum heat transfer. A large cross-section of the flow channel in the heat exchanger 3in1 provides low speed and low-pressure losses. The large dimensions of the heat exchanger air / refrigerant and the counter-flow design enable the complete evaporation of the refrigerant (preventing the return of the liquid to the compressor).

  • Page 22 5.5. Condensate drain Caution! Compressed air Before performing any maintenance on the drain ensure the dryer is vented and not under pressure. AUTOMATIC MECHANICAL CONDENSATE DRAIN Automatic mechanical condensate drain has been developed for fully automatic discharging of condensate from the compressed air system. Condensate accumulates in reservoir and when the level is high enough condensate is being discharged from the system without any compressed air loss.
  • Page 23 5.7. Safety functions Safety functions are implemented in the controller. For the protection against low and high pressure the high- and low-pressure switches are added (RDP/T 750 – 2600) LPS: Low-pressure protection device on the suction side of the compressor trips, if the pressure drops below the pre-set value.
  • Page 24 5.10. Hot gas bypass valve This valve works as capacity regulator. It adapts compressor capacity to actual evaporator load maintaining a constant temperature / pressure of the evaporator at about +2 °C. Fitted between the high- and low-pressure sides of the air-dryer refrigerant system maintain constant compressor suction pressure by injecting hot gas from the high-pressure side.
