Working principle of screw chiller:
Screw chiller is named screw chiller because its key component-compressor adopts screw type. The unit is made of gas refrigerant in the state of from evaporator; After adiabatic compression by the compressor, it becomes high-temperature and high-pressure. The compressed gas refrigerant is cooled and condensed at the same pressure in the condenser. After being condensed, it changes into liquid refrigerant, and then expands to low pressure through the throttle valve to become a gas-liquid mixture. The liquid refrigerant at low temperature and low pressure absorbs the heat of the cooled material in the evaporator and becomes the gaseous refrigerant again. The gaseous refrigerant enters the compressor again through the pipeline to start a new cycle. These are the four processes of freezing cycle. It is also the main working principle of screw chiller.
Application of screw chiller:
Screw chillers are mainly used in plastic industry: plastic molding, injection molding, extrusion, bottle blowing, thermal molding, mechanical industry: laser technology, welding, mechanical cutting, non-cutting processing, casting, electroplating, electronic industry: surface treatment, electroplating, electrophoresis, medical equipment, electronic industry, circuit board production, electronic chip manufacturing, chemical industry and other industries: chemical, paper, pharmaceutical, food processing Aluminum profile, aluminum alloy, tempered glass, coated glass production, ultrasonic cleaning, jewelry processing, leather, fur processing, ink production, aquaculture, etc.
