How to add fluoride to refrigeration machines: hot topics and operation guides on the Internet
Recently, the maintenance of refrigeration equipment has become a hot topic, especially the operation method of adding fluoride to the refrigerator, which has received widespread attention. The following is a compilation of relevant content that has been hotly discussed across the Internet in the past 10 days, combined with structured data and operation guides, to provide you with a detailed analysis.
1. Statistics on popular refrigeration equipment topics across the entire network (last 10 days)

| Ranking | Topic keywords | Search volume (10,000 times) | Main discussion platform |
|---|---|---|---|
| 1 | Refrigerator fluoridation steps | 28.5 | Baidu knows, Zhihu |
| 2 | The difference between R22 and R410A | 19.2 | Douyin, Bilibili |
| 3 | Fluoride pressure standard | 15.7 | WeChat community |
| 4 | Refrigerant leak detection | 12.3 | Tieba, Kuaishou |
2. The whole process of adding fluoride to the refrigerator
1. Preparation
• Check whether the pressure gauge, vacuum pump and other tools are complete
• Confirm the refrigerant type (needs to be consistent with equipment labeling)
• Wear protective gloves and goggles
2. Detailed explanation of operating steps
| steps | Operation content | Things to note |
|---|---|---|
| first step | Connect pressure gauge | The blue pipe is connected to the low pressure valve, the red pipe is connected to the high pressure valve |
| Step 2 | System vacuum | Lasts for more than 15 minutes, vacuum degree ≤-0.1MPa |
| Step 3 | Charge refrigerant | Liquid filling requires inverting the cylinder |
| Step 4 | Run the test | Observe whether the current and temperature difference are normal |
3. Solutions to common problems
•Abnormal pressure:Check the system for blockages or leaks
•Poor cooling effect:Confirm whether the filling amount meets the standard (refer to the equipment nameplate)
•Compressor overheating:Stop the operation immediately and check the system oil level
3. Comparison of parameters of different refrigerants
| Type | Working pressure (MPa) | Filling method | Environmental protection |
|---|---|---|---|
| R22 | 0.5-0.6 | Vapor phase filling | Not environmentally friendly |
| R410A | 0.8-1.0 | liquid filling | Environmentally friendly |
| R32 | 1.0-1.2 | Special equipment charging | Slightly flammable |
4. Safety precautions
1. It is strictly prohibited to work with open flames. Refrigerant will produce toxic gases when exposed to fire.
2. The refrigerant must be completely drained before system maintenance
3. The storage temperature of cylinders should be lower than 50℃ and avoid direct sunlight.
4. It is recommended to be operated by certified professionals
Through the above structured data and operation guide, we hope to help you correctly master the fluorination technology of refrigerators. If you need in-depth service, it is recommended to contact the official after-sales or professional maintenance team.
