[0005]
However, the pressure of the air conditioner with variable diversion function is unstable when it is turned on, and it is difficult to ensure the pressure difference between the inlet and outlet of the check valve, which leads to the on-off failure of the check valve, which makes the air conditioner unable to realize the function of variable diversion.

The invention relates to the technical field of intelligent household appliances, and discloses a method for controlling an air conditioner, which comprises the following steps: when the air conditioner is started, controlling an electronic expansion valve to be opened to the maximum opening degree; and under the condition that the electronic expansion valve is opened to the maximum opening degree, the air conditioner is controlled to run for set duration so as to adjust the inlet and outlet pressure difference of the one-way valve. The electronic expansion valve is controlled to be opened to the maximum opening degree, and the circulation speed of the refrigerant is increased; and under the condition that the electronic expansion valve is opened to the maximum opening degree, the air conditioner is controlled to run for set duration, the inlet and outlet pressure difference of the one-way valve meets the on-off requirement of the one-way valve, and the on-off failure probability of the one-way valve is reduced. The invention further discloses a device for controlling the air conditioner, the air conditioner and a storage medium.
Description
technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for controlling an air conditioner, an air conditioner, and a storage medium. Background technique [0002] The variable split design of the air conditioner means that when the air conditioner operates in different modes, the refrigerant forms different flow paths in the heat exchanger. Specifically, when the air conditioner is heating, the refrigerant in the heat exchanger can flow through more branches to reduce the system pressure drop; when the air conditioner is cooling, the refrigerant in the heat exchanger can flow through fewer branches to speed up the refrigerant cycle. [0003] The prior art discloses a heat exchanger, which has a plurality of heat exchange pipelines and a bypass pipeline communicated with the heat exchange pipelines. A one-way valve is installed on the bypass pipeline. When the air conditioner is in the heati...
