How to read refrigerants in air conditioners: analysis of hot topics on the Internet and practical guide
Recently, as the high temperature in summer continues, the frequency of air conditioner use has increased sharply, and the discussion about air conditioner refrigerants has become a hot topic on the Internet. This article combines hot topics in the past 10 days to provide you with structured data and analysis from the perspectives of refrigerant types, detection methods, frequently asked questions, etc.
1. Top 5 hotly discussed air-conditioning refrigerant topics across the Internet
| Ranking | Topic keywords | Search volume (10,000) | Main discussion platform |
|---|---|---|---|
| 1 | Symptoms of insufficient air conditioner refrigerant | 48.7 | Zhihu/Douyin |
| 2 | Differences between R32 vs R410A | 35.2 | Station B/Xiaohongshu |
| 3 | Homemade refrigerant testing method | 28.9 | Baidu Tieba |
| 4 | Refrigerant filling price | 22.4 | Meituan/58.com |
| 5 | Promotion of environmentally friendly refrigerants | 18.6 | Weibo/WeChat public account |
2. Comparative analysis of refrigerant types
| Type | GWP value | security | Applicable models | Market share |
|---|---|---|---|---|
| R22(Freon) | 1810 | Flammable and explosive | Old fixed frequency | 12% |
| R410A | 2088 | non-flammable | Frequency conversion before 2015 | 43% |
| R32 | 675 | Slightly flammable | New frequency conversion | 38% |
| R290 | 3 | Highly flammable | European model | 7% |
3. Self-checking method of refrigerant status
According to the measured data of popular Douyin maintenance accounts:
| Test items | normal behavior | abnormal behavior |
|---|---|---|
| Air outlet temperature difference | 8-12℃ | <5℃ |
| Operating current | Rated value±10% | dropped by more than 15% |
| Frost on the condenser tube | Even condensation | localized icing |
| compressor sound | steady buzz | Intermittent abnormal noise |
4. Maintenance market data
Real-time quotes from Meituan services:
| Services | 1 air conditioner | 1.5 HP air conditioner | 3 air conditioners |
|---|---|---|---|
| Refrigerant testing | 80-120 yuan | 100-150 yuan | 150-200 yuan |
| R32 raise | 200-260 yuan | 260-320 yuan | 400-500 yuan |
| System leak detection | 150-180 yuan | 180-220 yuan | 300-350 yuan |
5. Expert advice and precautions
1.Safety warning: R32 refrigerant is slightly flammable and requires vacuuming when filling. Non-professionals should not operate it by themselves.
2.Environmental trends: According to the national refrigerant substitution roadmap, refrigerants with a GWP value of >750 will be completely phased out after 2025. It is recommended that new air conditioners be purchased with R290 or R32 models.
3.Misunderstandings in use: Poor cooling effect ≠ lack of refrigerant, which may be caused by clogging of the filter (accounting for 63% of the failure rate) or poor heat dissipation of the outdoor unit.
4.Maintenance cycle: Under normal circumstances, the inverter air conditioner does not need to be filled with refrigerant within 5 years. Frequent leaks indicate that there are system loopholes and require a thorough overhaul.
Through the above structured data analysis, consumers can more scientifically judge the status of air conditioner refrigerants and avoid being charged unreasonable fees by unscrupulous merchants in the name of "fluoridation". It is recommended to perform professional maintenance regularly to ensure the cooling effect and extend the service life of the equipment.
