The invention discloses a control method and control device of an air conditioner, the air conditioner and a storage medium, and can be applied to the technical field of the air conditioner. The control method comprises the following steps that multiple electronic expansion valves are controlled to be opened at a first preset opening degree; first temperatures of multiple indoor units are obtained through power lines; a compressor is controlled to operate at a first preset frequency; it is determined that the compressor runs for a first preset time period, and second temperatures of the multiple indoor units are obtained through the power lines; and and it is determined that the first temperature of a current indoor unit and the second temperature of a current indoor unit meet a first preset condition, and the electronic expansion valve which is opened by the first preset opening degree at present is bound to the current indoor unit. According to the control method, a connection relation between the electronic expansion valves and the indoor units does not need to be judged manually, meanwhile, communication connection lines between an outdoor unit and the indoor units are omitted, the electronic expansion valves and the indoor units can be accurately connected and bound, and the probability of abnormal operation of an outdoor unit set to which the electronic expansion valves belong is reduced.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, a control device, an air conditioner and a storage medium. Background technique [0002] The multi-tube air conditioner is connected by one external unit and multiple internal units. The external unit is equipped with multiple electronic expansion valves, and the multiple electronic expansion valves respectively control the working status of the internal unit of the corresponding unit of the external unit. In related technologies, the electronic expansion valve is bound to the internal unit after manually judging the corresponding connection relationship between the electronic expansion valve and the internal unit. In this connection mode, during the one-to-one correspondence connection between multiple electronic expansion valves and multiple internal units, connection errors are prone to occur, resulting in abnormal operation of the e...
