Recently, as the high temperatures in summer continue, air conditioning repair and maintenance has become a hot topic on the Internet. The following is a compilation of popular content related to air conditioning fluorine flushing in the past 10 days (as of 2023), combined with structured data to provide you with a detailed operation guide.
1. Statistics on popular air conditioner fluoride flushing topics across the Internet
| keywords | Search volume (daily average) | Main discussion platform |
|---|---|---|
| Air conditioner not cooling | 12,000+ | Baidu, Douyin |
| Air conditioner fluoride price | 8,500+ | Meituan, 58.com |
| Tutorial on adding fluoride yourself | 6,200+ | Station B, Xiaohongshu |
| The difference between R22 and R32 | 4,800+ | Zhihu, Tieba |
2. Detailed explanation of the operation steps of air conditioning fluorine flushing
1. Determine whether fluoride flushing is needed
• Check the operating status of the air conditioner: the cooling effect is significantly reduced or completely failed
• Observe the copper pipe of the outdoor unit: frost or no obvious condensation
• Use a pressure gauge to detect: normal pressure range (R22: 5-6kg/cm²; R32: 8-10kg/cm²)
| Fault phenomenon | Possible reasons |
|---|---|
| Air outlet temperature difference＜8℃ | Fluorine deficiency or compressor failure |
| The outdoor unit frequently starts and stops | Insufficient/excessive fluoride |
2. Preparation of fluorine flushing tools
| Tool name | Purpose |
|---|---|
| refrigerant tank | R22/R32 and other corresponding models |
| pressure gauge set | Monitor system pressure |
| electronic scale | Accurate metering of filling amounts |
3. Professional operation process (it is recommended to be operated by certified personnel)
①System vacuum: Use a vacuum pump to pump to -0.1MPa and keep it for 30 minutes
②quantitative filling: Control the filling amount through an electronic scale (refer to the label on the model nameplate)
③Run the test: Observe that the pressure gauge is stable within the standard range and detect the outlet air temperature.
| Model | Recommended filling amount |
|---|---|
| 1.5 HP on-hook | 800-1000g |
| 3 cabinet machines | 1500-1800g |
3. Safety precautions
• R32 refrigerant is flammable and open flames must be prohibited
• Wear protective gloves and goggles when handling
• System leak detection must use a professional leak detector
• Waste refrigerants need to be professionally recycled and disposed of
4. Service Price Reference
| city | On-hook fluoride (yuan) | Cabinet machine fluoride (yuan) |
|---|---|---|
| Beijing/Shanghai | 150-300 | 300-500 |
| Second tier cities | 120-250 | 250-400 |
5. Frequently Asked Questions
Q: How long does it take to add fluoride to the air conditioner?
A: A normal sealing system does not need to add fluoride for 5-8 years. Frequent fluorine deficiency requires checking for leaks.
Q: Is it possible to add fluoride by yourself?
A: Operation by non-professionals involves safety risks and can easily cause system damage.
Through the above structured data and operation guide, we hope to help you fully understand the relevant knowledge of air conditioning fluorine flushing. If you need service, it is recommended to choose a qualified repairer through a formal platform.
