How does the electronic dryer of the dryer function?

2018-12-15 15:53:06

The pneumatic drain valve uses a working principle of cooling and dew condensation to dry the compressed air.

It mainly consists of three parts: heat exchange system, refrigeration system and electrical control system.

The hot, humid and moisture-containing compressed air from the air compressor is first pre-cooled by the air to the air heat exchanger; then the pre-cooled air is passed through the refrigerant circulation loop of the air-to-refrigerant heat exchanger. Further cooling, heat exchange with the cold air that has been cooled from the evaporator to the pressure dew point causes the temperature of the compressed air to further decrease.



After that, the compressed air enters the evaporator and exchanges heat with the refrigerant. The temperature of the compressed air drops to 0 ° C - 8 ° C. The moisture in the air is precipitated at this temperature, and the water and oil condensed in the compressed air are passed through the condenser. The impurities are separated and discharged out of the machine by an automatic drainer.

The dry, low-temperature air enters the air to exchange heat with the air exchanger, and the temperature rises and then outputs.
