What is the general reason why the air conditioner does not cool?

What is the reason why Midea's air conditioner doesn't cool? 1. The biggest possibility is that there is not enough freon in the air conditioner. If your air conditioner has been used for three years or more, the cooling effect will be reduced or not cooled. You just need to ask the after-sales maintenance personnel to add a little. In addition, the problems of freon leakage and the machine itself caused by improper installation are not ruled out;

2. It is also possible that the power supply voltage is insufficient, because the normal starting voltage of the air conditioner is 220V+- 10%. Generally, in China's power supply system, almost all compressors above 200V can be started. Above 180V, 70-80% can be started, and above 160V, only a few can be started. If the power supply voltage is too low, it will affect the normal operation of air conditioning products.

3. The power of air conditioner is not enough. If your indoor space is large, the cooling speed of the air conditioner will be slow. Attention should be paid when selecting air conditioner, cooling 150-250W/ m2, heating 250-350W/ m2. In addition, you also need to comprehensively consider the space height, horizontal orientation, sealing performance, resident population and other factors.

4. It is also possible that the external environment temperature is too high. If the indoor and outdoor temperature difference is relatively large, the refrigeration efficiency of the outdoor unit will be relatively low, so the refrigeration efficiency will be relatively slow or even unable to cool;

5. If the air conditioner is not cleaned and maintained for a long time, it will affect the refrigeration effect of the air conditioner because of dust accumulation and other reasons, and reduce the refrigeration effect of the air conditioner. If the room is not cleaned for a long time, it will also affect human health. If it is not cleaned for a long time, it will breed bacteria and pollute the air.

6. The copper pipe connecting the indoor unit and the outdoor unit is too long. In general, the maximum allowable length of connecting pipes of air conditioners shall not exceed 8m for one horse, 1.5-2 horses for more than two horses, and 10m. The height difference between indoor unit and outdoor unit shall not exceed 5 meters.
