The main components in commercial refrigeration are: 1. Compressor:

　　 Compressor is the heart of electric commercial refrigeration, and is the power for the refrigerant in the refrigeration system to keep circulating. The compressor and the motor On the same shaft, it is sealed in the shell and installed at the bottom of the commercial refrigeration. Household refrigerators generally adopt a crank connecting rod movable plug type or a crank sliding tube type, which has a simple structure and high power.

　2. The condenser

　　 transfers the heat absorbed by the refrigerant in the commercial refrigeration to the air. In the condenser, the refrigerant is cooled by high-pressure superheated steam to cool and condense into liquid. commercial refrigeration generally adopts an air-cooled condenser. According to different structures, it can be divided into two types: shutter type, steel wire disc type and steel wire coil type.

　3, filter drier

　　   The filter drier is installed between the condenser and the capillary tube, with a fine metal mesh and molecular sieve inside. The main function is to filter out the moisture and impurities in the white refrigerant, to prevent the occurrence of ice resistance and dirty resistance failure in refrigeration.

　4. Capillary

　　 is a throttling device connecting the drying filter and the evaporator. The main function is to adjust the pressure and expand, so that the high-pressure liquid refrigerant from the condenser vaporizes in the evaporator and absorbs heat. The thickness of the capillary tube directly affects the refrigeration effect of commercial refrigeration.

　5. Evaporator

　　The evaporator is a heat exchanger that transfers heat from commercial refrigeration to refrigerant. Installed inside the commercial refrigeration cabinet. The main function is to use the liquid refrigerant to boil under a certain pressure and absorb the heat in the box to achieve the purpose of refrigeration. The structure includes tube sheet type and aluminum sheet inflation type.
