The refrigeration dryer adopts the working principle of cooling and condensation, which is mainly composed of three parts: heat exchange system, refrigeration system and electrical control system Firstly, the compressed air enters the precooler for air-to-air or air-to-water heat exchange to remove part of the heat energy, and then enters the cold and hot air exchanger to exchange heat with the cold air that has been cooled to the pressure dew point from the evaporator, so as to further reduce the temperature of the compressed air After that, the compressed air enters the evaporator for heat exchange with the refrigerant The temperature of the compressed air drops to 0-8 ℃, and the water in the air is separated under this temperature After separation by the air-water separator, it is discharged by the automatic drainer The dry low-temperature air enters into the cold and hot air exchanger for heat exchange, and then it is output when the temperature rises.
