Freon is air conditioning refrigerant, air conditioning will not operate without it, the central air conditioning fluoride deficient performance is what, how to determine the central air-conditioning lack of fluoride? Can be tested according to the following steps:

central air conditioning fluoride shortage step:

air conditioning test normal open after a period of time to feel the wind blowing very cool, and can quickly reach the set temperature, the outdoor compressor can like refrigerators open for a while to stop for a while, it can be said to be normal.

central air conditioning and lack of fluoride step two:

measured by measuring indoor thermometer machine air inlet and outlet temperature, difference in temperature is above 8 as normal, the greater the temperature difference that air conditioning work better, good up to 15 degrees celsius.

central air conditioning step three: lack of fluoride in the

after ten minutes, open the indoor machine panel, you should see the evaporator (copper aluminum plate wear full heat exchange components) on evenly with condensed water (like dew), normal (air humidity is big, and less). If there is no half half, is the lack of fluoride central air conditioning performance, such as local frost or ice is not normal.

central air conditioning fluoride deficient step four: touch

such as outdoor machine in hand to touch the place, can be in the boot after ten minutes to touch. The outdoor unit has two copper valves, one with a thick copper tube, and one with a thin copper tube. Touch the valve should be two temperature difference; coarse fine than the low temperature, feeling cold compared to normal (in high temperature should also be condensed water), Zaimo outdoor unit of hot air is not hot, may also be the central air conditioning performance lack of fluoride.

central air conditioning fluoride deficient step five: observation

used more than half of the users, the valve pipe joint and the outdoor machine can inspect the indoor machine leaks obvious signs, such as leakage phenomenon obviously indicates that the machine has the leakage, because the oil leakage of oil will dissolve fluorine, fluorine leakage, leakage of fluorine will the oil spill.
lack of performance of the central air conditioning, there are many, but according to the above five steps, the basic judgment of the central air conditioning is the lack of fluoride, the completion of the central air-conditioning operation, can effectively improve the efficiency of central air-conditioning refrigeration.
