The control device includes a perceiving unit that perceives a cumulative operation time and a rotation speed distribution during operation of each of the pumps, a degradation degree derivation unit that derives a degradation degree of each of the pumps based on the cumulative operation time and the rotation speed distribution during operation of each of the pumps, and a determining unit that determines the pump to be next operated/stopped based on the degradation degree of each of the pumps. The degradation degree derivation unit further derives an increased amount of the degradation degree of each of the pumps in a predetermined period. The determining unit determines the pump to be next operated/stopped based on the increased amount of the degradation degree of each of the pumps in the predetermined period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control device","description":"A control device controls a plurality of inverter-driven pumps disposed between a heat source device and an air-conditioner.
