The refrigeration principle of car refrigerators is quite different from that of household refrigerators. In order to ensure the cooling effectChina Commercial Ice Machine Suppliers, most household refrigerators adopt compressor cooling; while car refrigerators focus on portability, so there are many options for cooling methods, and the principles are also different. .
After power on, the compressor works and sucks in the low-pressure, low-temperature gas refrigerant that has absorbed heat in the evaporator. After compression, it forms high-pressure, high-temperature vapor with a temperature of 55℃～58℃ and a pressure of 112～8 Pa, which enters the condenser. . Due to the throttling of the capillary tube, the pressure drops sharply.
Because the pressure in the evaporator is lower than that of the condenser, the liquid refrigerant immediately boils and evaporates, and the heat in the absorption box becomes a low-pressure, low-temperature vapor. It is sucked by the compressor again. In this way, the heat inside the refrigerator is continuously transferred to the outside of the box.
