This situation occurs because the outdoor unit of the air conditioner is frosted. Then, the air conditioner switches to the defrost function, causing the heating to stop. After the problem is resolved, the heating is turned on again, and so on. .
Or the amount of refrigerant in the air conditioning system is insufficient. After the indoor fan motor is turned on, the temperature of the coil drops quickly, causing the compressor to start and stop, and hot air starts to blow. Then it gradually becomes cold and windy.
After the air conditioner turns on the heating mode, the condenser of the outdoor unit will be frosted. At this time, the air conditioner will automatically turn on the defrost mode, resulting in no longer blowing hot air. After the frost is cleared, If the hot air continues to blow, the air conditioner will blow and stop for a while.
What should be paid attention to when using air conditioning and heating?
1. It is necessary to select the appropriate number of air conditioners according to the size of the space to meet daily use. If the indoor sealing effect is poor, or the air conditioning filter is not cleaned in time, heating will be affected.
2. The air conditioner settings should also be determined according to the actual usage. Do not set it too high, otherwise it will affect your health during use. Generally, the air conditioner temperature is about 10 degrees higher than the outdoor temperature, which is fine. Moreover, the temperature difference is not big, so it is less likely to feel uncomfortable when entering and exiting the air-conditioned room.
3. Indoor air circulation is also very important. After all, the doors and windows must be kept closed during the use of air conditioners. If ventilation is not performed in time, the indoor air will be too turbid, which is not conducive to users. of health. Therefore, it is necessary to open the window for ventilation every two hours or so of use.
