The compressor is the main core component of the industrial chiller. For the analysis of the core components of the screw chiller, the screw chiller refrigeration system is mainly divided into several equipment: compressor-condenser-expansion valve-evaporator. The basic principle is that the compressor compresses the refrigerant into a high-pressure saturated gas (ammonia or Freon), which is then condensed by a condenser. After throttling by the throttling device, it is passed to the evaporator, and the medium to be cooled is cooled and exchanged. For example, connecting the evaporator to each room in the building, the serpentine tube in the evaporator will exchange heat with the air, and then the cold air will be blown into the air of the room by the blast. The refrigerant in the evaporator serpentine tube is converted into low-pressure vapor back to the compressor after heat exchange, and then compressed by the compressed air-cooled chiller, so that the refrigeration system is completed by recycling. The heating system is also roughly the same, but in the opposite way.

The compressor of the screw chiller is the heart of the refrigeration system. Whether it is industrial refrigeration equipment, industrial chiller, air conditioning, cold storage, chemical industry, refrigeration technology, etc., there must be an important part of the compressor to protect, like a person. The heart, its quality will directly affect the efficiency of the chiller.

There are many types and forms of screw-type chiller refrigeration air-cooled chiller shrinkage machines. The working principle of the screw-type central air-conditioning unit compressors can be divided into two types according to the principle: volumetric type is the most common. The compressor of the screw chiller completes the compression and delivery process of the gas by changing the volume of the gas to repair the air conditioner! Any power equipment needs to have a motive force to complete the work, and the compressor is the same. It needs an electric motor (motor) to drive. The volumetric compressor is divided into two types: reciprocating piston type and rotary type: the reciprocating piston type changes the gas working volume by reciprocating movement of the piston in the cylinder; the piston type compressor has a long history and mature production technology. The rotary compressor includes a rotary vane (slider) rotary compressor and a screw compressor. At present, most domestic air conditioners are rotary compressors; screw compressors are mainly used for large refrigeration equipment, and now some large shopping malls. There are also many screw compressors used in office buildings.
