(Summary description)Constant temperature wine cabinet is a wine cabinet for storing red wine, with the characteristics of constant temperature and humidity. Like the constant temperature characteristic of wine cellar, the red wine cabinet has an ideal environment for storing red wine.

At present, there are three common refrigeration methods in the world: steam compressor refrigeration, absorption refrigeration and electric heating refrigeration. Red wine cabinet generally adopts compressor refrigeration and electric heating refrigeration (semiconductor electronic refrigeration). So what is the working principle of constant temperature wine cabinet? Let's get to know the red wine cabinet manufacturer Zhongshan Kaiteng Electric Appliance Co., Ltd

Working principle of constant temperature wine cabinet:

Electronic wine cabinet cooled by compressor main refrigeration system. The constant temperature wine cabinet of compressor is cooled by refrigeration system, which is composed of compressor, condenser, throttling part and evaporator. The four parts are connected into a closed system by copper tubes in a certain order, and a certain amount of refrigerant is filled into the system. The general refrigerant is Freon. In the past, R22 was used. At present, some new environmentally friendly refrigerants such as R410A, r-404a and r407 have been used in Freon compressor. Taking refrigeration as an example, the compressor sucks low-temperature and low-pressure freon gas from the evaporator, compresses it into high-temperature and high-pressure freon gas, and then flows through the thermal expansion valve (capillary), throttling it into 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 low-temperature and low-pressure freon gas, which is inhaled by the compressor. When the indoor air passes through the evaporator, the heat is released and the air temperature drops. In this way, the compression, condensation, regulation and evaporation cycle repeatedly, and the refrigerant continuously absorbs heat from the indoor air, thus reducing the space temperature. During heating, the flow direction of the refrigerant is changed by switching the four-way valve, so that the outdoor heat exchanger becomes the evaporator to absorb the heat of the outdoor air, and the indoor evaporation becomes the condenser to disperse the heat to the indoor, so as to achieve the purpose of heating.

The above is the introduction of wine cabinet manufacturers on the working principle of thermostatic wine cabinet.
