Abstract:
Provided is a control device capable of further equalizing the degradation levels of pumps. An air-conditioning system controller (110) controls a plurality of inverter-driven inverter pumps disposed between a refrigerator and an air conditioner, and is provided with: a grasping unit (116a) which grasps the operation integration times of the inverter pumps and the number-of-rotations distributions during operation of the inverter pumps; a degradation level derivation unit (116c) which derives the degradation levels of the inverter pumps on the basis of the operation integration times of the inverter pumps and the number-of-rotations distributions during operation of the inverter pumps; and a determination unit (116d) which determines an inverter pump to be operated/stopped next time on the basis of the degradation levels of the inverter pumps.
