Abstract

The application discloses a control method of an air conditioner, the air conditioner and a storage medium, if triggering the noise reduction function of an outdoor unit, acquiring the outdoor environment temperature, then determining the current temperature interval of the outdoor environment, and setting the frequency value associated with the temperature interval as a frequency threshold value, and further controlling the outdoor compressor to operate at a frequency less than or equal to the frequency threshold value. The upper limit of noise is limited through the frequency threshold, so that when the noise does not exceed the upper limit, other dimensional performance requirements are prioritized, when the noise exceeds the upper limit, noise reduction requirements are prioritized, and the use experience of a user on the air conditioner is effectively improved.
