Control method of air conditioner, air conditioner and storage medium

The invention discloses a control method of an air conditioner, the air conditioner and a storage medium. The air conditioner comprises a refrigerant circulating system and an energy storage device, a refrigerant pipeline between a first heat exchanger and a throttling device in the refrigerant circulating system is connected with a refrigerant branch in a heat exchange mode, and an air return pipe between a second heat exchanger and an air return opening of a compressor is connected with the refrigerant branch in parallel. The refrigerant adjusting module is used for adjusting the refrigerant flow in the air return pipe and the refrigerant branch, and the method comprises the steps that the refrigerant circulating system is controlled to conduct refrigeration operation, and state parameters are obtained; and when the state parameters reach the preset condition that the liquid refrigerant entering the compressor is too much, the refrigerant adjusting module is controlled to operate so as to increase the amoun
