In summer, air conditioning has become a "life-saving device" that almost everyone can't live without. But sometimes we find that the air conditioner doesn't seem to cool much, is the air conditioner broken?
Don't worry, it may be that the air conditioner is short of fluoride. However, before asking the maintenance personnel to add fluoride, we can first judge whether the air conditioner is really deficient in fluoride.
try
Half an hour after the air conditioner is turned on, whether it can quickly reach the set temperature (the cooling capacity needs to match the room and is not in extreme weather conditions), and listen to whether the sound of the air conditioner compressor is in a repeated start-stop state (turn on for a while and stop for a while). Otherwise, fluoride deficiency may occur.
see
During the normal operation of the air conditioner, when the water vapor in the air is cold, some small water droplets will be produced on the evaporator, which is what we call condensation.
The faster the condensate of the air conditioner is sent out, the larger the amount of water, the better the cooling effect of the air conditioner, and vice versa, the worse the cooling effect of the air conditioner.
If we find that the condensate of the air conditioner is draining more and more slowly, or the amount of water is getting less and less, it means that the air conditioner is starting to have a fluoride deficiency problem.
measure
Use a thermometer to measure the temperature difference between the air inlet and outlet of the indoor unit, and the difference is about 8-15 degrees Celsius within the normal range. If the temperature difference is too small, it may be fluoride deficiency.
touch
15 minutes after the air conditioner is turned on, if you can touch the air conditioner, touch the two valves of the outdoor unit (it must be operated under the premise of 100% safety, and users above the 2nd floor should operate with caution). If there is frosting in the thin tubes, it may be fluoride deficiency, and if there is frosting in the coarse tubes, it may be due to poor circulation of the system.
examine
Check the fittings of the indoor unit and the valve of the outdoor unit for greasy traces, if there are obvious traces of greasy, fluorine leakage may occur! Because oil fluorine is miscible and miscible against, fluorine leakage must leak oil, and oil leakage must leak fluorine! Fluorine escapes from the leak point and enters the atmosphere, while oil leaks and adheres around the leak point.
If there is a lack of fluoride in the air conditioner at home, you must not do it yourself, you must find professional and technical personnel to operate, if you do it yourself, there will be a certain danger, and it may cause greater damage to the air conditioner.
