With the improvement of the quality of life, we have gradually entered the era of technology. In hot summer, air conditioners have become an indispensable electrical appliance in our lives. With the continuous development of technology, air conditioners are not only easy to operate, but also can give People bring enjoyment and improve the quality of life, which has become the object of consumer purchase, but do you know about the frosting of the low-pressure pipe of the air conditioner? Do you know the reason and solution for the frosting of the low-pressure pipe of the air conditioner? Let me explain it to you Let’s introduce these two aspects in detail.
Frosting of low-pressure pipes of air conditioners – introduction to the causes of frosting
Reason 1. Insufficient refrigerant: After a split-type air conditioner has been used for a long period of time, refrigerant leakage or leakage will occur. After the refrigerant in the refrigeration system is reduced, the evaporation pressure is too low, causing the evaporator to freeze, and the freezing position is generally in the front part of the evaporator. The troubleshooting method is to deal with the leaking part first, add enough refrigerant, and the fault will be eliminated.
Reason 2: Compressor failure: Similarly, after the air conditioner is used for a long period of time, the compression efficiency of the compressor decreases, or the air distribution system of the compressor is damaged, resulting in low pressure and freezing. The freezing position is also in the front part of the evaporator, add some refrigerant to the former, and the fault can be eliminated. If the fault persists, the compressor must be replaced.
Reason 3: Too much refrigerant: Insufficient refrigerant will cause the air conditioner to freeze, and too much refrigerant will also cause the air conditioner to freeze. Some air conditioners re-inject refrigerant due to displacement, leakage, etc., and maintenance personnel operate Improperly adding more refrigerant, causing too much refrigerant to flow to the evaporator and partially evaporate and freeze. This kind of ice mostly freezes in the rear part of the evaporator and around the return pipe of the compressor, let off the excess refrigerant, and the fault will be eliminated.
Reason 4: The evaporator is too dirty: After the air conditioner is used for a period of time, the dust in the air or the microorganisms produced by the evaporator will accumulate on the evaporator, hindering the air circulation, resulting in reduced heat exchange, and the evaporator temperature is too low to freeze. ice. The freezing position is at the back of the evaporator. After the ice melts, flush the evaporator with water and brush along the fins with a soft brush. Be careful not to wet the electrical part. After cleaning, the fault is eliminated.
Frosting of air-conditioning low-pressure pipes—the solution
If the air conditioner freezes due to the failure of the thermostat, then the thermostat of the air conditioner needs to be replaced; if it is found that the evaporator of the air conditioner is too dirty, then the evaporator of the air conditioner needs to be cleaned thoroughly. Insufficient or excessive, then you need to eliminate or add refrigerant; if it is a compressor failure, it is best to replace the compressor of the air conditioner.
I believe that through the above detailed introduction to the causes of frosting of low-pressure pipes of air conditioners and the solutions, it will be helpful for you to repair the frosting of low-pressure pipes of air conditioners in the future. Air conditioners, as electrical products widely used in our lives, not only In our study, work provides a better environment, and can also improve the quality of life. We all know that the flexibility of anything can bring great convenience to our work and life. I believe that the above reasons and solutions for the frosting of the low-pressure pipe of the air conditioner can help you deal with the problem.
