How To Solve The Problem Of Freezing Outside The Air Conditioner

If there is a leak of fluorine in the air conditioner, it is recommended to ask the maintenance personnel to check it carefully. The indoor unit filter is blocked. You can adjust the unit to ventilation mode, and set the fan speed to the lowest gear to see if there is any air coming out of the internal unit. The air conditioners are all running normally, but the large copper pipes connecting the outdoor unit and the indoor unit are frosted, resulting in poor cooling effect or no cooling. The reason is that there is too much fluorine, or the indoor unit is not well ventilated. The air intake of the indoor unit is mostly because the filter screen is blocked and does not allow ventilation. It is enough to clean the filter screen. There are also many reasons that the back of the indoor unit evaporator is dirty and blocked, and the evaporator needs to be removed for cleaning. Don't look at the surface of the indoor evaporator, see if the back is dirty, you can only see it after disassembling the evaporator. If there is no problem with indoor air intake, it means that there is too much fluorine and fluorine is released. The thin copper tube of the outdoor unit of the air conditioner is frosted, the cooling effect is poor, and the indoor unit has flowing water and ice crystals. The reason why the thin tube is the liquid tube is the high pressure tube. The refrigerant coming out from there is low temperature, even if the low temperature is higher than the outdoor temperature, under normal circumstances there will be no frost, check whether the copper pipe is bent or not. The sound of running water in the indoor unit should be caused by insufficient refrigerant flow, and freezing is a chain reaction due to lack of fluorine.
