Is the air conditioner not refrigerated?5 methods to quickly determine whether the air conditioner is dehydrated

Correspondent Zhang Yuliang

The most indispensable of air -conditioning refrigeration is the refrigeration liquid, and the most common in refrigeration solution is Flun. If Freon is missing, even if every part in the air conditioner is intact, the air conditioner cannot be refrigerated normally. Because only the liquid Freon gasification can blow out a cold wind with a refreshing atmosphere.

People can determine whether Freon has leaks through the phenomenon of air -conditioning refrigeration abnormalities or oil leakage. If there is no air conditioner in the air conditioner outlet when the air conditioner is found, the refrigeration system failure, fluorion deficiency, and pipeline concave reasons need to be considered.

Under normal circumstances, Freon needs to be added every five years. If it is not operated properly during use, then the fluorine in the air conditioner is easy to leak in large quantities. In this case, it is necessary to add Freon appropriately. We can judge whether the air conditioner is dehydrated:

One trial: The wind blowing on the body after the air conditioner was opened normally, and it was cool to the body, and it was able to reach the set temperature quickly. The outdoor compressor could stop for a while like a refrigerator for a while, indicating that the air conditioner was normal.

Second test: Use thermometer to measure the temperature difference between the indoor machine in and the air outlet. The difference is above 8 ° C and the maximum can reach about 15 ° C. The larger the temperature difference, the better the work of the air conditioner.

Three views: After booting for more than ten minutes, open the indoor panel, and you should see that the evaporator (the component of the copper pipe is covered with aluminum sheet for thermal exchange) is evenly covered with condensate like dew In some cases, there is no case, indicating that the air conditioner is deficient in fluorine. In addition, local frost or freezing should be vigilant.

Four touch: If the outdoor unit can touch it, you can touch it with your hands for ten minutes. The outdoor machine has two copper valves, one connects the coarse copper tube and the other is a fine copper tube. Touch the two valves with your hands to have a temperature difference, and the thick temperature should be normal (when the temperature is high), you should also have condensed water). Then feel whether the wind blowing out of the outdoor unit is hot. It is a short -deficient manifestation.

Five investigations: Users who use the air conditioner for more than half a year, you can check whether there is obvious signs of oil leakage at the pipeline joint and outdoor machine valve of the indoor machine. Fluorofluoro is leaky, oil leakage must be leaked.
