Air-Cooled Magnetic Bearing Centrifugal Chiller.
Cooling capacity range from 350kW up to 1760kW. The air - cooled magnetic bearing centrifugal chillers adopt shell and tube flooded evaporator and shell and tube condenser.
The heat exchange tube adopts special layout make refrigerant flow improvement in the evaporator and the condenser to increase efficiency.
The unit adopts electronic expansion valve to control the volume of liquid refrigerant spraying into the evaporator precisely.
By controlling the stepping motor operation due to the different load, the special electronic expansion valve driving module can adjust open degree of valve to control refrigerant flow volume reaching the optimum efficiency.
The chillers are added with the economizer, which can improve degree of supercooling greatly, increasing efficiency by 10%
