Cold water chiller is generally composed of two or more than two independent refrigeration system, each system can be used single or two-stage compression refrigeration system. The two part is through a condensing evaporator connected, it is low temperature and high temperature of condenser, evaporator refrigerant cycle, namely high temperature cycle of evaporation is used in low temperature refrigerant cycle. In such a case, the heat absorbed by the low temperature cycle is transferred to the refrigerant in the high temperature cycle. The refrigeration cycle of the low temperature screw type cold water machine can not only meet the appropriate evaporation pressure at the lower evaporation temperature, but also can meet the moderate condensing pressure at ambient temperature.
      Low temperature screw chiller used in electroplating, electronics, machinery processing, business card printing, papermaking, textile, food and oil fields, low temperature screw chiller is widely used in centralized cooling way, convenient centralized management. Low temperature screw chiller can be customized according to the customer type of acid and alkali, the manufacturing process can be set into low temperature model, with low temperature refrigerant, has reached the process requirements of different customers.
