Recently, as the high temperatures continue in summer, air conditioning maintenance and refrigerant addition have become hot topics. The following are the discussion hot spots and structured operation guides on the addition of ammonia (refrigerant) in air conditioners across the Internet in the past 10 days to help users complete the operation safely and efficiently.
1. Statistics of hot topics in the past 10 days
| Topic keywords | Search volume (10,000 times) | Main discussion platform |
|---|---|---|
| Air conditioning refrigerant addition | 12.5 | Baidu, Zhihu |
| R22 ammonia refrigerant | 8.7 | Douyin, Bilibili |
| Symptoms of fluoride deficiency in air conditioners | 15.2 | WeChat, Xiaohongshu |
| Risks of DIY ammonia addition | 6.3 | Weibo, Tieba |
2. Operation steps for adding ammonia in air conditioners
1. Determine whether ammonia needs to be added
Common symptoms: reduced cooling effect, frost on the thin tubes of the outdoor unit, and operating current lower than the rated value. It is recommended to use a pressure gauge to check the system pressure first (normal R22 low pressure is 0.4-0.6MPa).
2. Preparation
| Tools/Materials | Specification requirements |
|---|---|
| refrigerant tank | R22 or corresponding model |
| Double meter valve group | With high and low pressure gauge |
| Vacuum pump | ≥2L/min |
| protective gloves | Anti-frostbite material |
3. Add process
(1) Close the high-pressure valve and connect the low-pressure pipe to the air-conditioning service port
(2) Empty the connecting pipe and open the refrigerant tank.
(3) Start the air conditioner and observe the pressure gauge, and slowly inject it to the standard value.
(4) Close the refrigerant tank first and then disconnect it
3. Safety precautions
| Risk type | Precautions |
|---|---|
| Frostbite | Wear protective gloves at all times |
| explosion | Keep away from open flames and no smoking |
| environmental pollution | Use recovery devices and prohibit direct discharge |
4. Professional advice
1. It is recommended to contact a certified technician to operate an old air conditioner (required by the "National Occupational Standards for Refrigeration Equipment Maintenance Workers")
2. New environmentally friendly refrigerants (such as R32) must be handled by professionals
3. After adding, a leak detector is required to check the tightness of the system.
5. Frequently Asked Questions
Q: How long does it take to add ammonia to a home air conditioner?
A: Under normal circumstances, there is no need to add it for 5-8 years. Frequent lack of ammonia indicates leakage.
Q: Can different refrigerants be mixed?
A: Absolutely prohibited! R22, R410A, R32, etc. have completely different compositions and pressures.
Through the above structured data and operation guide, users can have a more comprehensive understanding of the precautions for adding ammonia in air conditioners. It is recommended that non-professionals give priority to maintenance to ensure safe use.
