The role of each part of the refrigeration system (1) Compressor: After consuming a certain amount of external power, the gaseous refrigerant in the evaporator is sucked in, compressed to the condensing pressure and discharged into the condensation. Change from liquid to gaseous state; it plays the role of compressing and conveying refrigerant vapor; it is a low-pressure elevated pressure (gas)
(2) Evaporator: After the refrigerant boils (evaporates) to absorb the heat of the cooled medium, it changes from a liquid state to a gaseous state; it is low-temperature and low-pressure (external cooling).
(3) Expansion valve (throttle valve): throttling the condensed high-pressure liquid refrigerant to the required pressure of the evaporator through throttling, and then sends it into the evaporator.
(4) Condenser: Gaseous refrigerant condenses into a liquid after transferring heat to a cooling medium (water or air at normal temperature) during condensation.
Most of the above four works:
These devices are connected in sequence by pipes to form a closed system. When the system is working, the compressor sucks the low-temperature and low-pressure refrigerant vapor generated by the evaporator into the cylinder. After the compressor compresses, the pressure rises (the temperature also rises) to a value slightly higher than the pressure in the condenser. The high-pressure refrigeration steam is discharged into the condenser. (So ​​the compressor plays the role of compressing and transporting the refrigerant.) In the condensation, the high-temperature and high-pressure refrigerant vapor exchanges with lower temperature air (or normal temperature water) to condense into a liquid refrigerant. At this time, the liquid refrigerant expands After the valve is cooled (depressurized), it enters the evaporator and absorbs the heat of the object to be cooled in the evaporator and then vaporizes. In this way, the cooled object is cooled and the refrigerant vapor is sucked away by the compressor. Therefore, in the refrigeration system, a cycle is completed through four processes: compression, condensation, expansion, and evaporation.
