Control method and device of air conditioner, storage medium and air conditioner

Abstract

The application discloses a control method and device of an air conditioner, a storage medium and the air conditioner. The control method first determines a target current in response to a current control instruction, and acquires an actual operating current of a compressor. Then, the operating frequency of the compressor is adjusted according to the target current and the actual operating current, and the actual operating frequency of the compressor is acquired. After that, when the actual operating frequency periodically fluctuates in a preset resonance shielding band, the maximum operating frequency in the fluctuation period and the maximum operating opening of a throttling element are acquired. Finally, when the actual operating frequency reaches the maximum operating frequency in the fluctuation period, the throttling element is controlled to open to a target opening, and the compressor is controlled to increase the frequency according to the target current and the actual operating current, so that the actual operating frequency exceeds the resonance shielding band. In this way, accurate current control is realized, and the pipe breaking risk caused by the up-and-down fluctuation of the target frequency in the resonance band is avoided under the current-frequency control scheme.
