What is the cause of frost on the surface of air-conditioning compressor?
The evaporation of bad or fluorine fluorine compressor frost, under normal circumstances, there will be only a little thin frost in the air return opening, as long as the compressor stops working, then the cream will melt, heating when the outdoor temperature is too low or when the outdoor machine evaporator frosting thick compressor frosting.
Air conditioning compressor work at a high temperature, the surface can not frosting
The outdoor machine has frosted, indicating that the temperature is already low, there is no refrigerant problems.Frost indicates that the cooling plate of the indoor machine is also caused by low temperature, and the refrigerant at low temperature is cooled after expansion, resulting in frosting.The refrigerant at low temperature is caused by the air duct not passing through the cooling plate of the internal machine.
It's possible that the compressor doesn't work, otherwise it won't frost and check to see if it can be cooled,
