The refrigerated dryer adopts the working principle of cooling and condensation, and is mainly composed of three parts: heat exchange system, refrigeration system and electrical control system. The compressed air first enters the pre-cooler for air-air or air-water heat exchange, and then enters the cold and hot air exchanger to exchange heat with the cooled cold air that has come out of the evaporator to further reduce the temperature of the compressed air. After that, the compressed air enters the evaporator and exchanges heat with the refrigerant. The temperature of the compressed air drops to 0-8°C. The moisture in the air is precipitated at this temperature, separated by the gas-water separator, and then discharged through the automatic drain. The dry low-temperature air enters the hot and cold air exchanger for exchange, and is output after the temperature rises.
