Freeze one of the four large piecescompressorFrance
Taikang
It's the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction tube, drives the piston to compress it through the motor operation, and discharge the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to achieve the refrigeration cycle of compression → condensation (heat release)→ expansion → evaporation (heat absorption). Match different compressors according to the low temperature range and the size of the inner tank

Thermal expansion valveDenmarkThe role of the expansion valve in the refrigeration system: (1) throttling and reducing pressure: the high temperature and high pressure liquid refrigerant after condensing the condenser is throttling and reducing pressure, becoming a low temperature and low pressure vapor liquid mixture that is easy to evaporate, and entering the evaporator to evaporate and absorb external heat; Adjust the flow: according to the temperature signal obtained by the temperature sensing bag or the air box head, the expansion valve can automatically adjust the refrigerant flow into the evaporator to meet the changing needs of the refrigeration load. (3) Maintain a certain overheat, prevent liquid shock and abnormal overheating the expansion valve through the adjustment of flow rate to make the evaporator have a certain superheat, to ensure the effective use of the total volume of the evaporator, to avoid liquid refrigerant into the compressor caused by liquid shock; At the same time, it can control the superheat in a certain range to prevent the occurrence of abnormal overheating.
