Why is it still hot in the room when the air conditioner is turned on?

It's still hot in a cold air-conditioned room. Generally speaking, there are several reasons for this:

1, it may be that the power supply voltage is low, the outdoor compressor of the air conditioner is not started, and the machine is not working in the refrigeration state, so it is still hot.

2. The indoor network is too dirty and not cleaned, resulting in high-voltage protection of the refrigeration system.

3. The room is large and the air conditioner is small, and there is no air conditioner with normal cooling capacity in proportion. For example, if the room is 30 square meters, you need to install a small machine of 1.5p, that is, a 32-hour hanging machine. The cooling capacity of refrigeration can't meet the requirements and the temperature can't drop.

4. Air conditioning installation is three points and seven points. If there is an error in the installation of a good air conditioner, it is equivalent to not installing an air conditioner.
