Improvement method:

1. If you are exposed to the sun for a long time outdoors, it is recommended to install a sunshade.

2. This will also happen if the outdoor fan speed decreases. How about changing the starting capacitor? If the motor bearing is badly worn or poorly lubricated, it will also cause the motor speed to decrease, or the motor coil will be partially short-circuited, so it is necessary to replace the motor with a new one.

In fact, poor air conditioning refrigeration is not necessarily caused by lack of fluorine, but it is not good to add more freon, which will increase the workload of the compressor, lead to serious heating, affect the refrigeration effect, and seriously damage the compressor. The pipeline pressure should be controlled at 0.45 ~ 0.5 MP.

Note: The unstable or too low voltage of air-conditioning power supply will also affect the normal operation of air-conditioning compressor. Therefore, when using air conditioners, avoid using them with other high-power appliances.
