liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.

Causes of non-condensable gas in refrigeration system 1. Insufficient emptying of the refrigeration system before charging the refrigerant Before charging the refrigerator, the compressor cylinder in the refrigeration system, the condenser, the evaporator, and the piping of the system were filled with air. In order to eliminate these air before charging the refrigerant, the interior of the refrigeration system Vacuuming,

1. Test the power cord with an electric pen. The broken power cord of the freezer is also a cause of non-refrigeration. For this situation, we need to check whether it is a power problem. The general approach is to open the door and observe whether the lighting lamp in the box Light up. Look for signs of damage to the wires, such as being bitten by a mouse.

Common faults and causes of compressors Common compressor failures are as follows: L. The compressor cannot start normally The power supply voltage is too low, the motor circuit is poorly connected, or the exhaust valve is leaking, resulting in too high pressure in the crankcase. The energy regulation mechanism has failed.

The principle of the air-conditioning compressor is to maintain the circulation of the refrigerant in the refrigeration system by means of external force. The air-conditioning compressor sucks in low-temperature, low-pressure refrigerant vapor from the evaporator.
