An air conditioner control method, comprising: acquiring a current temperature of a chilled water of a unit at a preset period; calculating a difference value between the current temperature of the chilled water and the temperature of the chilled water set by the user; determining the target load of the unit corresponding to the difference value; the air conditioner control method being characterised by comprising: determining the target temperature of the chilled water and the target temperature of the cooling water corresponding to the target load of the unit; determining an evaporation parameter and a condensation parameter of the unit according to the target load of the unit, the target temperature of the chilled water and the target temperature of the cooling water; determining operation parameters of a compressor according to the target load of the unit, the evaporation parameter and the condensation parameter for the unit to operate according to the operation parameters, calculating a temperature difference between the current temperature of the chilled water and a temperature of the chilled water of the unit acquired in the previous period after determining the target load of the unit; determining whether the temperature difference is larger than the difference value; reducing the target load of the unit by a preset magnitude under the condition that the temperature difference is greater than the difference value; and determining the target temperature of the chilled water and the target temperature of the cooling water corresponding to the reduced target load of the unit; increasing the target load of the unit by a preset magnitude under the condition that the temperature difference is less than the difference value; and determining the target temperature of the chilled water and the target temperature of the cooling water corresponding to the increased target load of the unit. acquiring a current temperature of a chilled water of a unit at a preset period;
