The working principle of a compressor liquor cabinet is an electronic liquor cabinet that is mechanically cooled by a compressor into a refrigeration system. The compressor electronic wine cabinet achieves refrigeration through its refrigeration system, which consists of four basic parts: compressor, condenser, throttling component, and evaporator. Connect the four major components into a closed system in a certain order using copper pipes, and fill the system with a certain amount of refrigerant. The general refrigerant is Freon, which used to be R22. Some compressors have already used new environmentally friendly refrigerants such as R410A, R-404A, and R407 for Freon. Taking refrigeration as an example, the compressor sucks in low-temperature and low-pressure Freon gas from the evaporator and compresses it into high-temperature and high-pressure Freon gas. Then, it flows through a thermal expansion valve (capillary) and is throttled into a low-temperature and low-pressure Freon vapor liquid two-phase object. Then, the low-temperature and low-pressure Freon liquid absorbs heat from the air in the evaporator and becomes a low-temperature and low-pressure Freon gas, The low-temperature and low-pressure Freon gas is sucked in by the compressor. After passing through the evaporator, indoor air releases heat and the air temperature drops. Through repeated cycles of compression, condensation, throttling, and evaporation, the refrigerant continuously removes the heat from the indoor air, thereby reducing the temperature inside the space. During heating, the flow direction of the refrigerant is changed by switching the four way valve, making the outdoor heat exchanger an evaporator that absorbs the heat of the outdoor air, while the indoor evaporation becomes a condenser that dissipates the heat indoors, achieving the purpose of heating. Features and advantages: Good refrigeration effect: the minimum temperature can reach 5 ℃; The temperature control range is large, usually between 5-22 ℃, while semiconductor refrigeration is generally 10-18 ℃. The compressor wine cabinet is relatively less affected by environmental temperature, and even in high-temperature environments, the temperature inside the wine cabinet can still reach the ideal storage temperature for wine, while the semiconductor wine cabinet can only reduce the ambient temperature by 6-8 ℃. Stable performance: Adopting compressor refrigeration technology, mature technology, stable performance, and less prone to malfunctions. Long service life: Due to mature technology and the general use of variable frequency technology, the compressor works intermittently, so the service life of the compressor liquor cabinet is relatively long. The general service life of the compressor wine cabinet is 8-10 years; Semiconductor wine cabinets typically last 3-5 years
