Do air conditioning require regular fluorine
I used to think i needed it, and my air conditioning was used for three or four years, and i was thinking of adding some refrigerants this year. But i called after i sold it, and the workers didn't even come and told me:
“as long as it is unrepaired and undefended, no fluorine is added.”
At the same time, he added to me that if it was fixed or broken, it was not enough to add fluorine. It is also necessary to find the cause of the failure and to address the root causes — or, if fluorine is added, it will be short of fluorine in a few days。
So what was i, like, "ten air conditioning repairs, nine fluorine shortages"? It seems that, as the worker said today, there is no shortage of fluorine。
Fluorinated deficit at . 01
If the ac lacks fluorine, there must be three performances:
• refrigeration is not subjectively “not cool enough” as my air conditioner is not cold enough right now. Workers say it's because the weather is not hot enough and the humidity is not high enough to get cold when it gets hot。
The effect of air conditioning cooling is judged to be poor, mainly by winding temperatures. The temperature of the air conditioner in the wind vent can be measured when the air conditioner has just been turned on, and when the temperature exceeds 15°c, it is considered to be less effective。
• compressors do not stop working, regardless of whether the compressor is an in-house or a variable air conditioner. When indoor temperatures are met, the outdoors are shut down or power reduced。
It would therefore be useful to observe the state of the outdoors, and if the noise of the outdoors of the air conditioners remained low and the vibrations remained so high, it could basically be concluded that the outdoors were non-stop。
• the evaporation unit frosts when you suspect that the air conditioner is fluorine-deficit, can open the air conditioner for more than 20 minutes, then turn off the air conditioner, open the air conditioner panel, remove the filter and observe the evaporation under the filter。
If the evaporationer surface is frost, almost 100% can be concluded to be fluorinated. The outdoors are also seen with two valves on the side of the outdoors, the thicker of which also frosts when fluorine is lacking。
Fluorinated due to failure of . 02
After fluorine failure, you can call after sale. But when a worker arrives, he is not allowed to focus only on fluorinated fluorine and, more importantly, to find the reasons for the fluorine deficiency and the root causes of the problem. There are three common causes of failure:
• pipelines/interconnections are damaged by two metal tubes attached to the air-conditioning outdoors, which contain refrigerants (commonly known as fluorine). If the pipeline is leaked and fractured, the refrigerant in it is leaked, resulting in fluorine deficiency。
The focus is on the welding points of the pipes and the interfaces connecting the internal and external machines, which are the most vulnerable to leakage — fluorine deficiency due to damage to the pipes or connections, which must be accompanied by oil spills. So there's no need to take the pipes down and check and see where there's oil stains in the warm cotton。
• location of the evaporation/condenser failure evaporation unit, as already mentioned. The condensers are on the outdoors, with the whole back of the outdoors. They look alike. They're in the form of a grid。
If the evaporation or condenser is damaged or pierced, the refrigerant is also missing. But the two are generally strong and generally not bad unless they are human-induced. Also, the cost of maintenance was higher after the damage, and it was recommended that the air conditioner be replaced directly and that no maintenance be required。
• compressor failure is the least we would like to see, and compressor is the soul of air conditioning. Once damaged, the air conditioner not only loses the refrigerant, but also ceases to work, in the form of a “total non-working outdoor machine”。
Compressors are also the most valuable fittings on the whole air conditioner, so that if they are identified as compressor failure, they can be replaced directly with new air conditioners with no maintenance value at all。
Fluorinated fluorine deficiency due to ... 03 maintenance
As already mentioned, the air conditioners contained refrigerants. Therefore, if the two tubes need to be removed, the “fluorine harvest” must be done ahead of schedule, otherwise the refrigerants in the pipes will be leaked if the pipes are to be removed。
• fluorine harvesting must be done, especially when the slings are removed, because of the longer time the pipes are removed. When routine maintenance involves the dismantling of pipes, do not forget to instruct workers to perform fluorine collection。
• the installation of fluorinated refrigerants will remain in compressors for the time being, pending their release upon completion. But don't forget to do a “vacuum” before release, which is to take the air out of the pipe。
If the vacuum is not completed, refrigerants may mix with air composition. There is also a risk of air dilution, which affects the purity of refrigerants and hence the efficiency of work。
Whether it is to be removed or assembled, it is to be “recognised”. If your air conditioner is fluorinated after repairing or moving, remember to find the person responsible and make him responsible for restoring you。
