After the operation of the outdoor unit of my GREE air conditioner, the refrigeration can be done, but the rough copper pipes under the outdoor machine will frost. What's the trouble?
3, system micro plug will cause thick tube frosting4, improper operation, filled with other types of refrigerant, of course, this is rare
Air conditioning outdoor rough pipe (trachea) frosting in general, there are several situations1, refrigerant leakage, refrigerant is too small, resulting in back air pipe is too cold, will cause thick pipe frosting2, indoor filter screen blocked or indoor heat exchanger stains too much, resulting in poor ventilation, poor heat exchange
5, the fall temperature, rain when frost will occur, but also a normal phenomenon
