Abstract
Official abstract text for this publication.
A control device controls a plurality of inverter-driven pumps disposed between a heat source device and an air-conditioner. 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A control device configured to control a plurality of pumps disposed between a heat source device and an air-conditioner, the pumps being inverter-driven, the control device comprising: a perceiving unit perceiving a cumulative operation time of each of the pumps and a rotation speed distribution during operation of each of the pumps; a degradation degree derivation unit deriving a degradation degree of each of the pumps based on the cumulative operation time of each of the pumps and the rotation speed distribution during operation of each of the pumps; a determining unit determining the pump to be next operated/stopped based on the degradation degree of each of the pumps; and a storage unit storing weighting values respectively corresponding to the cumulative operation time of the pumps, the operation time of the pumps in a low-speed rotation region and the operation time of the pumps in a high-speed rotation region, and a number of start/stop cycles of the pumps, the degradation degree derivation unit further deriving an increased amount of the degradation degree of each of the pumps from a point when the pump is replaced, the determining unit determining the pump to be next operated/stopped based on the increased amount of the degradation degree of each of the pumps from the point, and the degradation degree derivation unit deriving the degradation degree of each of the pumps further based on the weighting values respectively corresponding to the cumulative operation time of the pumps, the operation time of the pumps in the low-speed rotation region and the operation time of the pumps in the high-speed rotation region, and the number of start/stop cycles of the pumps. 2. The control device according to claim 1 , further comprising a calculation unit calculating an operation time of each of the pumps in the low-speed rotation region and an operation time of each of the pumps in the high-speed rotation region based on the rotation speed distribution during operation of each of the pumps, the degradation degree derivation unit deriving the degradation degree of each of the pumps based on the cumulative operation time of each of the pumps, the operation time of each of the pumps in the low-speed rotation region and the operation time of each of the pumps in the high-speed rotation region. 3. The control device according to claim 2 , wherein the perceiving unit further perceives the number of start/stop cycles of each of the pumps, and the degradation degree derivation unit further derives the degradation degree of each of the pumps further based on the number of start/stop cycles of each of the pumps.
