1. The refrigeration system is mainly composed of five parts: refrigeration compressor, evaporator, condenser, thermal expansion valve and hot gas bypass valve. The refrigerant circulates continuously in the refrigeration system, undergoes phase change, performs multiple heat exchanges, and completes the cooling and cooling of the compressed air.
2. The heat exchange system is mainly composed of a heat exchanger (also known as a precooler or a regenerator), an evaporator tube and a cyclone separator. Complete cold energy recovery, provide cooling space and the role of gas-liquid separation.
3. The electrical control system is mainly composed of contactors, thermal relays, time relays, etc. A series of control and protection actions for the entire refrigeration system are completed through the electrical control system.

1. Refrigeration compressors are from American Danfoss, Japanese Panasonic and Daikin brands, with compact structure, low noise, high cooling power, high reliability, high efficiency and energy saving. The refrigeration compressor is equipped with overload protection function to ensure that the refrigeration compressor operates more stably and the system is more reliable.
2. The refrigeration system is controlled by Danfoss thermal expansion valve and thermal bypass valve (RD0200 and above). According to the load size of the dryer, the refrigerant supply can be adjusted reliably and effectively to achieve the purpose of energy saving.
3. The heat exchanger with the combined structure of volume type and sleeve type prevents scaling, reduces the load of the refrigeration system, and ensures the long-term reliable operation of the whole machine.
4. The heat exchange rate can reach 90%, which is 30% higher than that of similar products, and saves energy by about 10-20% compared with similar products.
5. The thickness of the copper tube used in the heat exchanger is 1mm, and the copper tube used in the evaporator is 0.5mm, which is thicker than the copper tube used in similar products, which greatly reduces the risk of leakage in the refrigeration system.
6. The high-efficiency cyclone-type blade baffle water separator can separate 99% of liquid water, and the gas-liquid separation effect is complete, avoiding the secondary evaporation of water and ensuring the drying effect of the cold dryer.
7. The electrical control adopts Schneider products to ensure the precise action and reliable operation of the dryer.
8. The domestic advanced electronic automatic drainer is used to reliably discharge the condensate out of the machine without causing airflow loss.
