Ice formation at the air outlet of the air compressor is a common problem, which can be caused by a variety of factors, the following are its causes and corresponding treatment and prevention methods:

1.Insufficient heat absorption in the evaporator: If the supply of liquid refrigerant to the throttle valve is normal, but the evaporator does not absorb heat effectively, it may cause the outlet to freeze.

2.Excessive supply of refrigerant: Even if the evaporator is endothermic properly, if the throttle valve has too much refrigerant supply, it can lead to icing.

3.Insufficient refrigerant: Insufficient freon can cause the compressor return pressure to be too low, which can cause icing.

Ways to deal with icing include:

1.Adjust the hot gas bypass: Icing problems can be mitigated by fine-tuning the hot gas bypass. The adjustment should not be too fast, generally after half a turn of adjustment, it should be paused, observe the operation of the system and the frost state, and make further adjustments as needed. Once the system is stable and the frost is gone, tighten the end caps.

2.Drain the ice: If the inside of the trachea is frozen, remove the trachea to remove the ice inside.

3.Heating treatment: Raise the temperature of the iced air tube to cause the ice to melt.

Measures to prevent icing include:

1.Maintain the temperature of the machine room: By increasing the temperature of the machine room, the air compressor and its components can be effectively prevented from freezing.

2.Increase the frequency of drainage: Especially in the cold winter months, increase the frequency of draining to avoid moisture staying in the system for a long time.

By taking appropriate treatment and preventive measures, the problem of freezing at the air outlet of the air compressor can be effectively solved and the stable and efficient operation of the air compressor can be ensured.
