Frascold refrigeration compressor unit
1. The working principle of the refrigerator
In the circulating system of the refrigerator, the compressor sucks in low-temperature and low-pressure refrigerant vapor from the evaporator, is adiabatically compressed by the compressor to become high-temperature and high-pressure superheated vapor, and then presses it into the condenser for constant-pressure cooling, and releases heat to the cooling medium. Then it is cooled into a supercooled liquid refrigerant.
The liquid refrigerant is adiabaticly throttled by the expansion valve to become a low-pressure liquid refrigerant, evaporates in the evaporator and absorbs the heat in the air-conditioning circulating water (air), thereby cooling the air-conditioning circulating water to achieve the purpose of refrigeration, and the low-pressure refrigerant flowing out is sucked into the compressor , This cycle of work.
Second, the structure of the refrigerator
The refrigerator is composed of a compressor, a condenser, an evaporator, and a throttling device. The compressor is used to compress the refrigerant vapor from a low-pressure state to a high-pressure state; the condenser cools the superheated vapor of the refrigerant discharged from the compressor and condenses it into a refrigerant liquid. The heat of the refrigerant in the condenser is discharged to the cooling medium.
