What's the difference between the refrigerating capacity of a refrigerator of 4.5kg and 1 1.0kg? The salesman always tells me to buy a 4.5 kg compressor, and then

The compressor is the power of the refrigerator, equivalent to the heart of the refrigerator. It compresses the refrigerant, increases the pressure and temperature of the refrigerant and promotes the circulation of the refrigerant in the system.

The refrigeration principle of the refrigerator is that the refrigerant is sucked in by the compressor in the form of gas, compressed into high-temperature and high-pressure vapor, and enters the condenser through the exhaust pipe. The refrigerant radiates heat to the outside air, condenses into high-pressure liquid, enters the capillary through the filter, and enters the evaporator for vaporization after being intercepted and decompressed. The refrigerant liquid absorbs external heat and evaporates into dry saturated steam, thus reducing the temperature in the refrigerator. The refrigerant becomes low-pressure superheated steam, which is sucked back by the compressor, and so on.

Meiling has at least two alternative compressors for each refrigerator, and the compressors used at the same time are high-efficiency compressors of well-known brands at home and abroad, such as EMBRAK, zanussi and Huayi. Each batch will be different, and they are well-known brands at home and abroad. Please feel free to use them.

It is my pleasure to serve you. Thank you for your trust and support for Meiling products!
