Suzhou Central air conditioning maintenance about the causes of frost in the indoor unit of air conditioning:

Household air conditioning indoor unit frost this is a common failure, where is the reason, we have to make a detailed judgment:

1. There are leakage points in the air conditioning refrigeration system, so that there will be less freon in the air conditioning refrigeration system.

The second point: 2. The speed of the inner fan may be slow, and frost will appear.

Third point: the indoor machine is too dirty, there will be frost.

Fourth point: sometimes the temperature of the indoor evaporator is too low to form water droplets or cause frost, affecting the refrigeration effect. Therefore, the air conditioner has a low temperature detection function, and the machine runs

When the central air conditioning refrigeration function, when the temperature sensor detects that the evaporator temperature is lower than 2.5 degrees, it will automatically stop the compressor operation to prevent the temperature from continuing to fall

Indoor unit evaporator frosting, can effectively protect the air conditioner, maintain good cooling effect. Your air conditioning condition should be checked by a professional.
