What is the reason for the poor heating effect of air conditioning in winter?

1, the reason of poor heating effect of air conditioner-low outdoor temperature or poor electricity environment.

When the outdoor temperature is too low, the air conditioner can't work normally. When the outdoor temperature is too low, the outdoor unit of the air conditioner cannot defrost and the air conditioner cannot heat. In addition, low voltage may directly affect the cooling and heating effects of air conditioners.

2. The reason why the heating effect of air conditioner is not good-the heating power of air conditioner is too small.

The number of applicable air conditioners varies with the size of the room. If the indoor air is not tightly sealed or exposed to the sun, the corresponding number of air conditioners should be larger. If the room area is relatively large and fewer people choose air conditioning, it is easy to cause this problem.

3. The heating effect of air conditioner is not good-there is no electric auxiliary function, so the heating effect is not good.

After market research, the main reason for the poor heating effect of many air conditioners is that there is no electric auxiliary heating function, but this situation is very prominent in old air conditioners.

4. The reason for the poor heating effect of air conditioning-there is too much dust in the air conditioning filter.

There is too much dust in the air filter of the air conditioner, and the air outlets of the internal and external machines are blocked by foreign objects. The function of the filter screen is to absorb the dust in the air. If there is too much dust and it is not cleaned up in time, it will hinder the air circulation, resulting in a decrease in the air output at the air outlet, which will lead to the lack of heating capacity in the machine.

Conventional air conditioning maintenance

1. Remove the sundries in the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation net cover for foreign objects. At the same time, keep the vents open.

2. Clean the surfaces of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, carefully remove the panel, scrub it with a soft rag, and gently scrub the heat exchanger of the indoor unit with a small brush to remove the harmful accumulation of dust and breeding bacteria. However, it should be noted that the heat sink is very thin aluminum, which is easy to deform after being stressed, so brush it carefully.

3. Remove the dust from the filter screen. When cleaning the filter screen, cut off the power supply first, and then open the air intake grille; Take out the filter screen, clean the filter screen with water or vacuum cleaner, the water temperature should not exceed 40 degrees, clean it with hot wet cloth or neutral detergent, and then wipe it with dry cloth. At the same time, it is not allowed to clean the filter screen with pesticides or other chemical cleaners.

4. Remove dirt and deposits from the drainage part. The drainage part is easy to deposit dirt, so it must be disinfected thoroughly on a regular basis to ensure smooth drainage and prevent bacterial reproduction.

5. Check others. Comprise a power cord, a plug board and a switch; Check the status of consumable parts, such as air deflector, sterilization and dehumidification, photocatalyst, etc. , to ensure that the air conditioner is in good condition.
