Working principle
Compressor wine cooler is an electronic wine cooler that is mechanically cooled by a compressor into a refrigeration system. The compressor electronic wine cabinet realizes refrigeration through its refrigeration system. The refrigeration system consists of four basic parts, namely compressor, condenser, throttling component and evaporator. The four large pieces are connected by a copper tube into a closed system in a certain order, and the system is filled with a certain amount of refrigerant. The general refrigerant is Freon. In the past, R22 was usually used. In some compressors, Freon has adopted new environmentally friendly refrigerants such as R410A, R-404A and R407. Taking refrigeration as an example, the compressor sucks the low-temperature and low-pressure Freon gas from the evaporator into a high-temperature and high-pressure Freon gas, and then flows through a thermal expansion valve (capillary) to throttle the 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 space in the evaporator, and becomes a low-temperature and low-pressure Freon gas, and the low-temperature and low-pressure Freon gas is sucked by the compressor. After the indoor air passes through the evaporator, heat is released and the temperature of the air drops. Such compression-----condensation----throttle----evaporation repeatedly cycles, the refrigerant constantly takes away the heat of the indoor air, thereby reducing the temperature in the space. During heating, the flow direction of the refrigerant is changed by the switching of the four-way valve, so that the outdoor heat exchanger becomes an evaporator, absorbs the heat of the outdoor air, and the evaporation in the room becomes a condenser, and the heat is dissipated indoors. To achieve the purpose of heating.
Features advantages
Good cooling effect: the lowest temperature can be 5 °C; the temperature control range is large, generally between 5~22 °C, and the semiconductor refrigeration is generally 10~18 °C. The compressor wine cabinet is less affected by the ambient temperature. Even in a high temperature environment, the temperature in the wine cabinet can still reach the ideal storage temperature of the wine, and the semiconductor wine cabinet can only drop 6~8 °C than the ambient temperature.
Stable performance: Compressor refrigeration technology, mature technology, stable performance, not easy to fail. Long life: Because the technology is mature, and the frequency conversion technology is generally used, the compressor works intermittently, so the compressor wine cabinet has a long service life. The compressor wine cabinet generally has a service life of 8 to 10 years; the semiconductor wine cabinet is generally 3 to 5 years.
