1. An air conditioner control method, applied in a central air conditioner, wherein the air conditioner control method comprises:
acquiring a predicted load of the central air conditioner at a current moment when a startup instruction or a shutdown instruction corresponding to an indoor unit in the central air conditioner is detected;
determining whether the predicted load meets a change condition for an outdoor unit; and
adjusting an operating status of the outdoor unit in the central air conditioner based on the predicted load if the predicted load meets the change condition for the outdoor unit, wherein determining whether the predicted load meets the change condition for the outdoor unit comprises:
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;
calculating a load difference between the predicted load and the total load, and calculating a ratio of the load difference to the preset gross load; and
determining whether the ratio is greater than a preset value, wherein it is determined that the predicted load meets the change condition for the outdoor unit when the ratio is greater than the preset value.
