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.
