Reasons for overheating of air conditioner compressor

- Apr 20, 2020-

1. If it is a fixed frequency machine, the reasons are:

① The lack of fluorine causes the exhaust temperature of the press to be too high and thermal protection appears.

② The capillary is blocked by foreign objects, which leads to excessive throttle, excessive exhaust temperature and thermal protection.

2. If it is a frequency converter, the reasons are:

① The opening of the electronic expansion valve is too small, resulting in high exhaust, high power, and thermal protection.

② It is also caused by the partial blocking of foreign objects.

③ Caused by lack of fluoride. It is recommended to add fluorine first, and then determine the throttling device.
