1. An air conditioner control method, applied in a central air conditioner comprising an indoor unit and a plurality of outdoor units, the air conditioner control method comprising:
determining a time interval between a current moment and a preset moment at which work is started is less than or equal to a predetermined maximum time duration;
in response to determining that the time interval is less than or equal to the predetermined maximum time duration, acquiring a preparatory demand load and a startup combination load corresponding to the central air conditioner;
determining a start moment of at least one of the plurality of outdoor units to be started on a basis of the startup combination load and the preparatory demand load;
detecting a startup instruction or a shutdown instruction;
in response to detecting a startup instruction or a shutdown instruction corresponding to an indoor unit in the central air conditioner, acquiring a predicted load of the central air conditioner at the current moment;
acquiring a total load corresponding to outdoor units that are in startup status in the central air conditioner and a preset gross load corresponding to all outdoor units in the central air conditioner;
determining a ratio based on the predicted load, total load and the preset gross load;
determining the ratio is greater than a preset value;
in response to determining that the ratio being greater than the preset value; and
adjusting an operating status of the at least one of the plurality of outdoor units in the central air conditioner based on the predicted load.
