[0002] A large number of copper tubes are used in the refrigerator compressor. If the refrigerator is turned on when there is a lot of water in the refrigerator system pipes, dirt will appear on the inner wall of the copper tube of the refrigerator refrigeration system, and the copper tube will be blocked over time, which will cause the resistance along the way to increase and the compressor output to decrease, which will greatly reduce the refrigeration effect and even almost have no refrigeration effect. In severe cases, it may cause the machine to overload and even seriously damage the refrigerator. Therefore, a pair of copper tubes of the compressor need to be cleaned.
