1. Try it:
   Turn on the air conditioner and set the cooling mode. The temperature is adjusted to 8℃ lower than room temperature. After a period of normal opening, you can feel the cold air and reach the set temperature quickly.
  The operating condition of the outdoor compressor is that it stops for an instant and turns on for an instant. This situation is generally not a problem.
  2, test one test:
   Take a thermometer and place it at the air outlet of the air conditioner. After about 10 minutes, investigate whether the change of the thermometer is almost the same as the room temperature. If it is about the same as the room temperature, but the compressor has been working, it is likely that the air conditioner has leaked fluorine.
  3, take a look:
   Take a look at the condition of condensate discharge: If the air conditioner has a good refrigeration effect, the condensate discharge speed is also quick. On the contrary, there is less condensate and poor refrigeration, which may be the lack of Freon.
Second, look at the indoor unit evaporator: After turning on for a period of time, open the panel of the indoor unit and check the condition of the condensed water on the evaporator. If it is evenly distributed, it is normal (the condensed water is more due to the high air humidity, and vice versa) . If the distribution is half and half not, it needs to be considered due to fluorine deficiency. If some frost or icing is found to be abnormal, there may be fluoride leakage.
   4. Touch it:
   If the outdoor unit is in a low position and can be touched under safe conditions, it can be touched by hand after a period of time to feel the temperature.
   Where to touch: two copper valves and hot air from the outdoor unit.
  The outdoor unit has two copper valves. The thin tube is a high pressure valve and the thick tube is a low pressure valve. The Freon in the high-pressure valve is liquid, and the pressure is high during operation, so it will be very hot. The freon in the low pressure valve is gaseous and the temperature is relatively low. Therefore, there is a temperature difference between the two when you touch it. The temperature of the thick copper pipe is lower than that of the thin copper pipe. It is normal to feel cooler.
   Touch the hot air of the outdoor unit again. If it is hot, there is generally no problem. If it is not too hot, it may be considered to be lack of fluoride.
   5. Check:
  Users who have used it for more than half a year can check their air conditioner first. Check whether there are obvious traces of oil leakage at the pipe joints of the indoor unit and the valve of the outdoor unit. If so, consider fluorine leakage. Because oil and fluorine are mutually miscible, oil leakage will leak fluorine, and fluorine leakage will cause oil leakage.
