Very strange Why does the air conditioning and refrigeration suddenly malfunction

Commonly used home appliances like air conditioners are very common in our lives, but in the process of use, large appliances such as air conditioners often have one or another failure. Therefore, how to use such air conditioners in summer and keep away from abnormal air conditioners. ? Then you might as well take a look at the common faults of the air conditioner.

　　 Below, the air conditioner in my home often has a temper and I don’t know what to do as a good friend. Let’s take a look.

　　 The air conditioner suddenly heats up under cooling conditions. What causes this situation?

1. When the weather is extremely hot, when the air conditioner reaches or approaches the set temperature, the compressor stops, the fan of the outdoor unit rotates, and the indoor unit sends natural wind. Because of the high outdoor temperature, the air feels hot when the natural wind is sent. , It is recommended to observe whether the air conditioning system is not cooling after a few minutes;

　　2. Check what mode is set. If it is automatic mode, the air conditioner set temperature is higher than the room temperature, and the air conditioner cools. If it is lower than the room temperature, the air conditioner will heat;

　　3. If there are no problems with the above items after inspection, you can call the professional air-conditioning maintenance service number and ask professional technicians to come to your door for service.

　　 Very strange Why does the air conditioning and refrigeration suddenly malfunction? How often does the air conditioner need to add Freon?

　　 There is no fixed time for adding Freon to the air conditioner. This is mainly based on the cooling effect of the air conditioner and the pressure in the air conditioning system. If these are normal, there is no need to add Freon, nor does it need to be added regularly.

　　What kind of "noise" the indoor unit makes when the air conditioner is working is normal?

　　 1. The wind noise of air conditioner operation, at this time, the corresponding wind speed can be adjusted to improve the corresponding wind noise;

　　2. The "crack" sound of the plastic parts of the air conditioner expands and contracts. This kind of sound cannot be completely avoided and is a normal phenomenon;

　　 3. The sound of the refrigerant being rapidly vaporized and liquefied in the pipeline. 　　 The air conditioner sometimes makes a "cracking" sound during the first ten minutes of starting, is it normal?

　　 Generally, when heating in winter, the temperature of the indoor unit of the air conditioner differs by tens of degrees from the ambient temperature, which generally causes the housing material of the indoor unit to expand and contract with heat, and the housing materials are likely to make a "cracking" sound due to friction. This is normal and will not affect performance. After the air conditioner runs for more than ten minutes, the sound will automatically disappear when the difference between the shell temperature and the ambient temperature is small.

　　 Some people think that the slightly smelly wind from the air conditioner is caused by the leakage of Freon, right?

　　 Freon is odorless, and air conditioner Freon is not allowed to leak. The so-called odor generally comes from indoor smoke and other odors. The new air conditioner adopts the strong adsorption effect of the activated carbon high-efficiency filter layer, which can not only remove tiny dust particles, but also remove smoke, odor and other odors, so that air purification is greatly improved.
