How to add fluoride to air conditioner? Under what circumstances should air conditioners be fluoridated?

In the hot summer weather, air conditioning has become an indispensable household appliance. At present, most household air conditioners are fluorine systems. The lack of fluorine in air conditioner will cause poor refrigeration (heating) effect of air conditioner, protective shutdown, water leakage (sometimes spraying water) of indoor machine and freezing of indoor evaporator. Under what circumstances should air conditioners be fluoridated? Let's take a look at how to fluoride the air conditioner. In hot summer weather, air conditioning has become a necessary household appliance in our bedroom and living room. At present, most household air conditioners are fluorine systems. The lack of fluorine in air conditioner will cause poor refrigeration (heating) effect of air conditioner, protective shutdown, water leakage (sometimes spraying water) of indoor machine and freezing of indoor evaporator. If it is serious, it will also reduce the service life of air conditioners or waste electricity. Under what circumstances will the air conditioner be fluorinated? Let's take a look at how to fluoride the air conditioner.

How to add fluoride to air conditioner?

1. How to add fluorine to the air conditioner? Turn on the air conditioner; When fluoride is added in summer, the air conditioner can be directly operated in refrigeration mode. The fluorination of air conditioner can't add fluoride in heating state, so when adding fluoride in winter, it is necessary to pull the reversing valve line by heating method to force the air conditioner to enter cooling state.

2. Connect fluorination 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. In this process, the air and dirt in the fluorination tube must be discharged.

3. Pressure measurement and fluoride addition; Observe the low pressure in summer. The ambient temperature is about 32 degrees Celsius and the pressure is controlled at about 0.45MP. How to add fluoride to the air conditioner? Observe the high pressure during heating in winter, and control it around 1.7MP after the pressure stabilizes.

4. Dismantle fluorination equipment; Air-conditioning fluorination: remove the fluorination equipment in the water-making state and tighten the sealed receiver of the external machine; If the equipment is removed when the air conditioner is heated with fluoride, it will cause a lot of freon leakage.

5. Fluorine addition is completed. Fluorination of air conditioners For air conditioners suspected of leaking, detergent foam should be used for inspection.

Under what circumstances should air conditioners be fluoridated?

1, under what circumstances should air conditioners be fluorinated? Use for more than 5 years (any split air conditioner will naturally leak freon);

2. Fluorine is added to air conditioners that have been moved for many times (air conditioners will consume some freon when they are moved empty);

3. When the air conditioner is fluoridated in summer, the exposed part of the thick pipe (that is, the low-pressure pipe) of the outdoor unit connection point is not condensation or cold;

4. The outdoor fan is not hot in summer;

5. Summer return air pressure (thick pipe) is lower than 0.4 MPa.

6. The running current of the compressor is less than the fluoride in the normal air conditioner indicated on the nameplate;

7, high pressure pipe (thin tube) frosting in summer;

8. In summer, the indoor unit of the air conditioner freezes or blows fog (sometimes accompanied by water leakage of the indoor unit);

9. In winter, touch the cold air conditioner with thick pipes at the copper pipe interface of the external machine to add fluoride;

10, the air conditioner with leakage point is fluoridated;

1 1, the air conditioner will stop after ten minutes (under-voltage protection or overheating protection).

Summary: Here is a brief introduction to the knowledge of how to add fluoride to air conditioners and under what circumstances. What I want to say is that air-conditioning fluorination sounds easy, but it actually contains many details that need attention, so users must choose a regular company when choosing an air-conditioning fluorination company to avoid being deceived.
