How to check whether the air conditioner is leaking fluorine
Fluorine leakage in air conditioners is one of the common faults, which can lead to reduced cooling performance, increased power consumption, and even damage to the compressor. The following are the inspection methods and precautions for fluoride leakage in air conditioners that have been hot topics on the Internet in the past 10 days for your reference.
1. Common symptoms of fluoride leakage in air conditioners
| Symptoms | Possible reasons |
|---|---|
| Refrigeration effect deteriorates | Insufficient Freon leads to reduced heat exchange efficiency |
| Increased operating noise | The compressor is overloaded due to lack of fluorine |
| Evaporator frost | Abnormal system pressure leads to low temperature frost |
| There are oil stains on the pipe joints | Freon leaks bring out refrigeration oil |
2. 5 ways to check for fluorine leakage in air conditioners
1.soapy water test
Apply soapy water to pipe joints, valves and other leak-prone parts and observe whether bubbles are formed. This is the most economical and practical detection method.
2.Electronic leak detector detection
Use a professional electronic leak detector to detect the leakage close to the pipeline. The instrument will sound an alarm. This method is highly accurate but requires specialized equipment.
| Detection method | Advantages | Disadvantages |
|---|---|---|
| soapy water method | Low cost and simple operation | Small leaks are difficult to detect |
| Electronic leak detector | High sensitivity | Equipment is expensive |
| Fluorescence leak detection | Accurate positioning | Need to add fluorescent agent |
3.Pressure gauge testing
Connect a pressure gauge to measure the system pressure. Normal R22 refrigerant low-pressure side pressure should be 0.4-0.6MPa and high-pressure side 1.5-2.0MPa.
4.Temperature detection method
Measure the air outlet temperature. The normal temperature difference should be between 8-12℃. If the temperature difference is too small, there may be a lack of fluorine.
5.Run current detection
Use a clamp meter to measure the operating current. If the current value is lower than 30% of the rated value, there may be a lack of fluorine.
3. Emergency treatment for fluorine leakage from air conditioners
After discovering fluoride leakage, you should immediately:
1. Turn off the air conditioner power
2. Open windows for ventilation (Freon is non-toxic but may displace oxygen)
3. Contact professional maintenance personnel
4. Do not add refrigerant yourself
4. Measures to prevent fluorine leakage from air conditioners
| measures | Description |
|---|---|
| Regular inspection | Inspect pipe connections annually before use |
| avoid shock | The outdoor unit must be installed firmly |
| Professional installation | Ensure the bell mouth connection specifications |
| Anti-corrosion | Seaside areas must prevent salt spray corrosion |
5. Maintenance precautions
1. Must be operated by professionals holding refrigeration operation certificates
2. Completely recover the residual refrigerant before maintenance
3. Use special materials to replace seals
4. After maintenance, pressure maintenance and leak detection must be carried out
Through the above methods, you can accurately determine whether the air conditioner is leaking fluorine. It is recommended to ask professionals to conduct a comprehensive inspection every 2-3 years, which can not only ensure the cooling effect, but also extend the service life of the air conditioner. If fluorine leakage is found, it must be repaired in time to avoid greater losses.
