摘要
PURPOSE:To reduce the power of a circulating pump by matching the quantity of flow of a water heat source to be circulated in a system with the necessary quantity of a unit group. CONSTITUTION:A pump P' whose discharge is controllable is provided as a pump for circulating a water heat source. This pump P' is a one-unit variable flow-rate type or consists of plural pumps P1 and P2 connected in parallel. Temperature values obtained by temperature detectors in units U, the number of units U in operation, and the quantity of circulating flow are calculated by a control circuit, and on the basis of its indication value, the discharge of the pump P' is controlled to match with an actual necessary quantity.
