Principle of Refrigeration Air Dryer

Clicks: 2071
The principle of the refrigerated air dryer is to inject humid and high-temperature compressed air into the pre-cooler (for high-temperature type) to dissipate heat and then flow into the heat exchanger to exchange heat with the cold air discharged from the evaporator to make the compressed air entering the evaporator. The temperature is lowered.

The heat exchanged compressed air flows into the evaporator through the heat exchange function of the evaporator and exchanges heat with the refrigerant. The heat in the compressed air is taken away by the refrigerant, the compressed air is rapidly cooled, and the moisture in the humid air reaches a saturation temperature and rapidly condenses. The condensed water is agglomerated to form water droplets, and is rotated at a high speed by a unique gas-water separator. The water is separated from the air by the action of centrifugal force, and the water is discharged from the automatic drain valve after separation. The air pressure dew point after cooling is as low as 2 °C.

The cooled cold air flows through the air heat exchange and exchanges heat with the hot humid air of the inlet. When the heat exchanged cold air raises the temperature by absorbing the heat of the inlet air, the compressed air passes through the secondary condenser of the refrigeration system. (Peer-independent design) Re-heat exchange with high-temperature refrigerant to fully heat the outlet temperature to ensure that the outlet air line does not condense. At the same time, the cold source of the outlet air is fully utilized to ensure the condensation effect of the machine's refrigeration system and ensure the air quality of the machine outlet.
