Abstract: A method for controlling an ice storage air-conditioning system includes: adjusting parameters of the ice storage air-conditioning system in a current cooling mode or when switching a cooling mode based on an outlet temperature of a plate heat exchanger of the ice storage air-conditioning system; and controlling the ice storage air-conditioning system to perform a cooling operation based on the parameters of the ice storage air-conditioning system.

Abstract: An air conditioner water system, a control method therefor, and a control device thereof, the method includes acquiring the pressure difference and temperature difference between a water intake pipe and a water discharge pipe of an air conditioner water system, the water intake pipe being connected to an inlet of a host module of the air conditioner water system, and the water discharge pipe being connected to an outlet of the host module; detecting and confirming that the pressure difference is less than or equal to a preset pressure difference, and controlling the operating frequency of a water pump of the air conditioner water system according to the pressure difference; and detecting and confirming that the pressure difference is greater than the preset pressure difference, and controlling the operating frequency of the water pump of the air conditioner water system according to the temperature difference.

Abstract: A method and device for controlling an air conditioner, and a computer readable storage medium. The method for controlling an air conditioner includes: upon detecting a power-on or power-off command corresponding to an internal unit of a central air conditioner, acquiring a current predicted load of the central air conditioner; determining whether the predicted load meets an external unit change condition; and if so, adjusting an operating state of an external unit of the central air conditioner on the basis of the predicted load.

Abstract: A control method and apparatus for water pumps in an air conditioning system. The control method includes: obtaining the number of water pumps currently running, the current speed ratios and the current running lift of the water pumps; calculating a control range of the speed ratios; determining whether the current speed ratios are in the control range of the speed ratios; switching the number of running water pumps so as to enable the speed ratios of the water pumps to fall within the control range of the speed ratios. The number of water pumps can be switched according to the running number of water pumps and the lift of the water pumps, allowing the water pumps to run in the high-efficiency interval under the full-load working condition to achieve variable-frequency energy-saving control of the water pumps and reduction of running power consumption of the air conditioning system.
