The word refrigeration can only be said to be a technical term, strictly speaking, it is wrong. No scientist in that country in the world can create "cold". We call the method of cooling objects to the required temperature by using mechanical equipment, which is the term.
Refrigeration Circulator Structure:
The refrigeration cycle 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 discharged from the compressor and condenses into a refrigerant liquid, and the heat of the refrigerant in the condenser is discharged to the cooling medium.
Working principle of refrigeration cycler:
In the refrigeration cycle system, the compressor sucks low-temperature and low-pressure refrigerant vapor from the evaporator, and adiabaticly compresses the compressor to become high-temperature and high-pressure superheated steam. It is then forced into the condenser for constant-pressure cooling, and releases heat to the cooling medium. Cooled to subcooled liquid refrigerant.
The liquid refrigerant is adiabaticly throttled by the expansion valve to become a low-pressure liquid refrigerant, which evaporates and absorbs the heat in the air-conditioning circulating water (air) in the evaporator, thereby cooling the air-conditioning circulating water to achieve the purpose of cooling. The low-pressure refrigerant flowing out is drawn into the compressor , So cycle work.
