How to judge the lack of fluoride in the air conditioner-how to judge whether the air conditioner is lack of refrigerant

As we know, once the air conditioner has no refrigerant, it is worse. Because the air conditioner is not cooling, it is really uncomfortable if the air conditioner cannot be used in the summer. Air conditioning is very common too. I believe that everyone will not be unfamiliar with air conditioners. Everyone knows that air conditioners are fluorinated, and non-fluorine inverter air conditioners do not mean that fluorine is not added. People now have misunderstandings about non-fluorine air conditioners. In fact, fluorine-free air conditioners need to add fluorine, but the added 'fluorine' needs to be professional. How to judge the lack of fluoride in air conditioners? Let's take a look today how to judge whether the air conditioner is lack of Freon.

How to judge the lack of fluoride in air conditioners? How to judge that the air conditioner lacks Freon

1. The air conditioner blows to the body after it is normally turned on for a period of time. The wind is very cold and can reach the set temperature quickly. Then it's normal. Of course, the compressor of the outdoor unit can be turned off for a period of time like a refrigerator, which can be said to be normal. But if it is not cooled after opening, it is a problem.

2. Use a thermometer to measure the temperature difference at the indoor air inlet. The difference is higher than 10°C, which is normal. The greater the temperature difference, the better the working conditions of Gree air conditioners, which is about 15°C.

Three. Ten minutes after the air conditioner is started, open the indoor unit panel, you should see the evaporator (part of the copper pipe is used for heat exchange with aluminum plates) evenly covered with condensed water, such as dew, it is normal (When the air humidity is high, there are many, and vice versa. If half and half are unavailable, it may be due to lack of fluoride. Such as partial frost or ice formation is abnormal.

Four , Touch---If you can touch the outdoor unit with your hands, you can touch it ten minutes after starting. The outdoor unit has two copper valves, one with a thick copper tube and the other with a thin copper tube. Manually one of the two There should be a temperature difference between; the thicker one should be lower than the fine temperature, and the colder one is normal (when the temperature is high, the condensate should be there). Touching the hot air of the outdoor unit is not a hot phone. If it is not hot, it may Lack of fluorine.

5. Users who have used the machine for more than half a year can check the indoor unit pipe joints and outdoor unit valves for obvious signs of oil leakage. If there is obvious oil leakage, the machine is leaking because the oil is Fluorine-soluble. The leakage of oil must leak fluorine, and the leakage of fluorine must leak oil.

How to judge the lack of fluorine in the air conditioner?

1. Turn on the air conditioner. When adding fluoride, the air conditioner can be directly operated in the cooling mode. Because the operation of adding fluorine cannot be carried out in the heating state, when adding fluorine in winter, the method of heating and reversing the valve line is used to force the air conditioner into the cooling state.

Second, connect the fluorine-containing equipment; after the air conditioner is started normally, connect the fluorine-adding equipment from the process port on the low-pressure valve side of the outdoor unit. During this process, the air and the fluoride pipe must be discharged Dirt.

Air conditioners generally need to add a refrigerant for three to five years. If the refrigerant is sufficient, then the air conditioner can be cooled to make people comfortable. This At that time, don’t just add refrigeration at will. Because refrigerants have specialized people to help them, they have professional fluorination equipment. Remove the fluorination equipment in the crucible state, and tighten the seal of the external machine. If the equipment is heated, Will cause a lot of fluorine leakage. Of course, after adding fluoride. For air conditioners suspected of leaking, please check the detergent foam.
