How to tell if the air conditioner has fluorine?
With the arrival of high temperatures in summer, the frequency of use of air conditioners has increased significantly, and the cooling effect of air conditioners is closely related to the content of Freon (refrigerant). Many users find that the cooling effect is poor when using air conditioners, and they suspect that it may be caused by fluorine deficiency. So, how to judge whether the air conditioner is deficient in fluorine? The following is a summary of the hot topics on the Internet in the past 10 days on how to determine fluorine deficiency in air conditioners.
1. Common symptoms of fluoride deficiency in air conditioners
When the air conditioner is deficient in fluoride, it will usually show the following symptoms. Users can use these phenomena to initially judge whether fluoride needs to be added:
| performance | Detailed description |
|---|---|
| Reduced cooling effect | After the air conditioner has been running for a period of time, the air outlet temperature is not low enough and the indoor cooling is slow. |
| Increased operating noise | The compressor may emit abnormal noise due to increased load due to lack of fluorine. |
| frost or ice | Frost appears on the evaporator or connecting pipe, especially on the low-pressure pipe. |
| Abnormal operating current | Use a clamp ammeter to measure the operating current, which is significantly lower than the rated value. |
| Abnormal temperature of high pressure pipe | The high-pressure pipe is not hot or the temperature is obviously low. |
2. Professional testing methods
For ordinary users, you can preliminarily determine whether the air conditioner is deficient in fluorine through the following simple methods, but the most accurate way is to ask professional maintenance personnel to detect it:
| Detection method | Operation steps | Judgment criteria |
|---|---|---|
| Thermometry | Use a thermometer to measure the air outlet temperature | The normal temperature difference should be between 8-12℃ |
| Pressure gauge testing | Connect a pressure gauge to measure system pressure | The normal pressure on the low pressure side of R22 refrigerant is 0.4-0.6MPa |
| Current detection | Measure operating current with clamp meter | The deviation from the rated current should not exceed 10% |
| observation method | Check the connecting pipe joints for oil stains | Oil stains may indicate a leak |
3. Things to note when adding fluoride to air conditioners
If it is confirmed that the air conditioner needs to be fluorinated, you need to pay attention to the following matters:
1.Choose formal maintenance services: Adding fluoride requires professional equipment and skills, and it is not recommended for users to do it by themselves.
2.Check for leaks: Simply adding fluoride will not solve the leakage problem, the leakage point must be found and repaired.
3.Use the correct type of refrigerant: Different air conditioners use different refrigerant types and cannot be mixed.
4.Add appropriate amount: Too much or too little refrigerant will affect air conditioning performance.
5.Regular maintenance: It is recommended to do a comprehensive inspection and maintenance every year before use.
4. Air conditioning maintenance suggestions
In order to prevent the air conditioner from being affected by fluorine deficiency, daily maintenance is very important:
| Maintenance items | Recommendation cycle | Things to note |
|---|---|---|
| Clean filter | once a month | Avoid dust accumulation that affects ventilation |
| Check cooling effect | Use season begins | Early detection of fluoride deficiency |
| Professional comprehensive inspection | once a year | Including pressure detection, circuit inspection, etc. |
| Outdoor unit cleaning | twice a year | Keep heat dissipated well |
5. Frequently Asked Questions
Q: How often does it take to add fluorine to the air conditioner?
A: Under normal circumstances, air conditioning refrigerant is a closed cycle and does not require regular fluoridation. If there is a lack of fluorine, it means there is a leak in the system, and the leak point should be repaired first.
Q: What is the general price of fluoride?
A: The price of fluoride varies depending on the region, the number of air conditioners and the type of refrigerant, and is generally between 200-600 yuan. Prices that are too low may run the risk of shoddy products.
Q: Does a new air conditioner need to be fluorinated?
A: Newly installed air conditioners do not need to be fluorinated. If the cooling effect of the new air conditioner is not good, it may be due to installation problems or other faults.
Through the above methods and precautions, users can better judge whether the air conditioner is deficient in fluorine and take corresponding measures in a timely manner to ensure that the air conditioner exerts its best cooling effect in the hot summer.
