How to fill air conditioners with fluorine: hot topics and operation guides on the Internet
Recently, as the high temperature in summer continues, air conditioning maintenance and fluoride filling have become hot topics on the Internet. The following is a compilation of popular content in the past 10 days (as of October 2023), combined with the operation steps of air conditioner fluoride filling, to provide you with a structured guide.
1. Hot topics on the entire network and hot spots related to air conditioning
| Ranking | Topic keywords | heat index | Related content |
|---|---|---|---|
| 1 | Air conditioner not cooling | 98,000 | Fluorine filling operation, fluorine leakage detection |
| 2 | Fluoride filling cost | 65,000 | Average market price, DIY risk |
| 3 | Environmentally friendly refrigerant | 42,000 | R32 alternatives, safety regulations |
2. Detailed steps for filling air conditioners with fluorine
1. Determine whether fluoride filling is needed
• The air conditioner still does not cool after running for half an hour
• The copper pipes of the outdoor unit are frosted or dripping abnormally.
• The pressure gauge detects low pressure below 0.4MPa
| Detection tools | normal value range | abnormal behavior |
|---|---|---|
| pressure gauge | 0.4-0.6MPa | The pointer fluctuates violently |
| Infrared thermometer | Air outlet temperature difference ≥8℃ | The temperature difference is less than 5℃ |
2. Fluoride filling operation process
(1)Safety preparation: Turn off the power and wear protective gloves
(2)Connect devices: Connect the fluorine-filled pipe to the low-pressure valve interface
(3)Drain lines: Open the valve of the fluorine bottle to discharge the air
(4)Quantitative charging: Observe the pressure gauge to the standard value
| Air conditioner type | Single charge amount | Reference duration |
|---|---|---|
| 1.5 HP on-hook | 600-800g | 15-20 minutes |
| 3 cabinet machines | 1200-1500g | 25-30 minutes |
3. Things to note and hot issues
•price dispute: There is a big difference in fluoride charging charges that are hotly discussed on the Internet. It is recommended to confirm the fluoride content pricing method in advance.
•Environmental regulations: R22 refrigerant will be banned from 2023, and new environmentally friendly refrigerants such as R32/R410A need to be used
•Risk of own operation: A popular Douyin video shows that 90% of DIY failure cases are caused by leakage due to unsealed valves.
4. Comparison of maintenance services
| Service channels | average quote | Service guarantee |
|---|---|---|
| Official after-sales service | 200-300 yuan/time | 6 months warranty |
| Third party platform | 150-250 yuan/time | Warranty 1-3 months |
