The working principle of a refrigerator
In the circulation system of the refrigerator, the compressor inhales low-temperature and low-pressure refrigerant steam from the evaporator, which is adiabatically compressed by the compressor into high-temperature and high-pressure superheated steam, and then pressed into the condenser for constant pressure cooling, and heat is released to the cooling medium, and then cooled into a supercooled liquid refrigerant.
