[0002] The refrigerator compressor is the core component of the refrigerator refrigeration system. Its main function is to absorb heat from the refrigerant on the low-pressure side of the refrigeration system and compress it into high-temperature and high-pressure gas, and then discharge this high-temperature and high-pressure gas to the high-pressure side of the refrigeration system, dissipating the heat energy to the outside through heat dissipation, thereby achieving a refrigeration effect. The refrigerator compressor is generally installed at the bottom of the back of the refrigerator and is protected and packaged by the refrigerator compressor rear cover protection plate structure.
