Is the fluoridation of Gree air conditioner a thick tube or a thin tube? Nanchang air-condition maintenance

Fluorine in the air conditioner is added from the liquid filling hole of the thick pipe at a pressure of 4.5-5.5KG, and the discharge speed of the condensate pipe of the outdoor unit is observed. If the condensed water is discharged quickly and the displacement is large, it shows that the air conditioning refrigeration effect is very good. However, the water droplets on the evaporator of the air conditioner are unevenly distributed or frosted locally, indicating that the air conditioner is in a fluorine-deficient state. It should be noted that in the process of adding fluorine to the air conditioner, it is necessary to add refrigerant Freon to the air conditioner compressor with professional props. There are two ways to add fluoride to air conditioners: 1. The suction pipe of the compressor needs to be welded again, and the process pipe needs to be repaired before fluoride can be added. 2. Fluorination is carried out through the high-pressure process pipeline on the compressor. 3. If fluoride is added too much, general air conditioners will have poor refrigeration or no refrigeration at all, but some special air conditioners will have other situations. Otherwise, some types of air conditioners have too much fluorine content, which will lead to over-current protection of the compressor due to excessive current. When the air conditioner is fluorinated and the positive pressure is "zero MPa", vacuum treatment is not needed. If fluoride is added for about one minute, the gauge pressure will rise.
