HEAT SOURCE WATER CONTROL METHOD AND HEAT SOURCE WATER CONTROL DEVICE

WIPO Patent Application WO/2018/159703

A1

A heat source water control method, wherein a heat source water control device performs a water feed differential pressure acquisition step, an opening acquisition step, a target water feed differential pressure calculation step, and a water feed differential pressure control step. In the water feed differential pressure acquisition step, the water feed differential pressure of the heat source water fed from a heat source device to a plurality of use-side heat loads. In the opening acquisition step, the degree that at least one valve from among the valves that are provided in each of the use-side heat loads and that regulate the supply volume of the heat source water supplied to the use-side heat loads is opened is acquired. In the target water feed differential pressure calculation step, the target water feed differential pressure, which is the target value for the water feed differential pressure in order to set the degree of opening to a target value, is calculated on the basis of the acquired water feed differential pressure and the acquired degree of opening. In the water feed differential pressure control step, the water feed differential pressure is controlled on the basis of the maximum water feed differential pressure, which is the maximum value from among the calculated target water feed differential pressures.
