Step 1: First of all, set the air conditioning to a lower temperature, run for about half an hour, and then put your hand in the outlet, if the feeling is not so cold, indicating that the refrigeration effect is not ideal, which is actually a manifestation of fluorine deficiency.

Step 2: Then open the panel of the indoor unit, remove the filter, if only part of the evaporator dew or frost, indicating that the refrigerant is not enough.

Step 3: Next, look at the outdoor unit, if the high-pressure pipe, that is, the thinner of the two pipes, there is an obvious frosting phenomenon, which also shows that the air conditioner is already short of fluorine.

Step 4: Then look at the connecting pipe there are no oil stains, if the oil leakage also means that the fluorine has been leaked, because refrigerants and frozen oil equipment have a certain degree of mutual solubility, fluorine leakage is bound to leak oil, oil leakage is bound to leak fluorine.

Step 5: Finally, if conditions permit, you can feel the outdoor unit blowing out of the wind has a sense of heat, if not hot is also a manifestation of the shortage of refrigerants.

The above is to judge whether the air conditioning is lack of fluorine, for maintenance workers, also need to pass professional tools to determine whether fluorine is needed, If nothing is detected, it is obviously unprofessional to add it directly.

Perhaps for many users, this traditional air conditioning is very inconvenient to use, maintenance is also quite troublesome. At this time, a simple portable and no need of freon air conditioner may be a good choice for them.
