Application£ºThe use of water-cooled screw chiller machine is widespread, such as rubber, electroplating, electronic, construction, machinery, metal, chemical, pharmaceutical, food and preservation, and other industries. Mainly used is in central air conditioning system or large industrial refrigeration. Detail£ºBecause using the key parts screw compressor, so it is named screw chiller machine. It can be divided into single screw compressor, twin screw compressor. It has good HMI interface, precise temperature control, precision energy control, grading and stepless energy control, reliable operation, high efficiency, easy to maintain, with reliable protection and accessories. Screw chiller machine major works:Refrigerant gas from evaporator unit is compressed by the compressor, and become high temperature and high pressure state. Compressed refrigerant gas goes into a condenser, condensed with isobaric cooling, then change to liquid, and expanded to a low pressure through the throttle valve into the gas-liquid mixture. The liquid refrigerant is under low temperature and low pressure, absorbing heat in the evaporator cold substance, become back into the refrigerant gas, it goes through the pipeline to re-enter the compressor, start a new cycle.
