Several symptoms of fluorine deficiency in refrigerators in summer

In summer, the frequency of use of refrigerators is relatively high, and the intensity of use is relatively high, so fluorine deficiency is prone to occur. How to judge whether the ice water machine is lack of fluoride in summer? The answer is that through various observations, we can finally determine whether the freezer is deficient in fluorine. If it is not deficient in fluorine, it should not be added, and if it is deficient in fluorine, it should be filled with sufficient refrigerant immediately!

Several symptoms of fluorine deficiency in refrigerators in summer:

First, the compressor load becomes larger.

Although there are many reasons for the compressor load to increase, the compressor load will inevitably increase if the refrigerator lacks fluorine. In many cases, if the air-cooled or water-cooled system has no heat dissipation failure, the compressor load can be determined The increase is due to lack of fluorine.

Second, the exhaust temperature is high.

High exhaust temperature is a common phenomenon in refrigerators. The pressure and temperature gauge at the exhaust end can clearly read the exhaust temperature. High exhaust temperature is not a rare phenomenon, which causes many people to face the refrigerator. The negative response when the exhaust temperature is too high. In fact, the high exhaust temperature should be paid attention to whether it is caused by abnormal operation of the oil separator, lack of refrigerating lubricating oil or lack of refrigerant, or other problems.

Third, the cooling capacity decreases and the cooling efficiency becomes lower.

When the refrigerating capacity of the refrigerator is reduced, the reasons may be various, but undoubtedly, as long as the refrigerator is short of fluorine, especially when there is a large amount of fluorine, the refrigerating capacity of the refrigerator will definitely be reduced to a large extent. Businesses make an impact.

Fourth, the energy consumption is large and the compressor wears out.

Due to the lack of refrigerant, the chiller cannot meet the refrigeration demand and the chilled water outlet temperature is not up to standard. Therefore, the compressor will increase the load to meet the chilled water outlet demand, which will result in high power resource consumption and high compressor wear.

In many cases, it is not easy to observe fluorine deficiency, especially for large-scale industrial refrigerators. The cooling capacity and cooling efficiency are reduced, which is not easy to detect. It is recommended that the refrigerator maintenance and operating personnel can pass electronic leak detection Use the instrument to detect leaks, or find other more effective methods to find and solve the problem of fluorine deficiency in the refrigerator.

According to the editor’s experience, there is a high possibility that the lack of fluorine is caused by damage to the pipes through which refrigerant management or condensers and other refrigerants flow, as well as problems with valves. If fluorine is lacking, it must be inspected. After leaking, determine the leak point, and then repair the leak. After confirming that the refrigerant will not continue to leak and the leak is successfully repaired, start the freezer again.
