1, the treatment is as follows: (1) leak detection: the air conditioning leaks, generally the valve port joints are not tightened or loose, or the outdoor copper tube is broken at a certain position, first deal with it.
(2) Add refrigerant, add it at runtime, or you don't know how much refrigerant it leaks.
2. If the screw is loose, you can handle it. If the welding place is leaked, you can only find a professional maintenance person to deal with it.
3, the maintenance staff will put all your air-conditioning refrigerant, and then in the place where the welding leaks the fluorine leaking oil, after the welding is completed, the air-conditioning system should be blown with nitrogen, and then the vacuum pump is used to vacuum and add fluorine.
4. Method for judging refrigerant leakage: open the casing panel of the air conditioner indoor unit, and remove the air filter grid, and then observe the frosting area of the evaporator. If it is found that only a small part of the surface of the evaporator produces frost. This indicates that the refrigerant in the air conditioner is seriously insufficient or has caused partial leakage. This is because it circulates inside the pipeline.
