refrigeration principle

Low temperature refrigeration is carried out in a closed refrigeration system. The compressor sucks in low-pressure gas refrigerant from the low-pressure end of the evaporator, and compresses it into high-temperature and high-pressure gas, which is sent to the condenser. By dissipating heat, it condenses into high-pressure liquid, flows through a drying filter to remove moisture and impurities, and then enters the evaporator through a capillary tube throttling liquid. At this time, due to the sudden decrease in pressure, the liquid quickly boils and evaporates to absorb heat, causing the temperature inside the box to decrease. The evaporated low-pressure gas refrigerant is then sucked back by the compressor, and so on, circulating the box/The indoor temperature drops to the target temperature.
