Title:
熱源水制御方法及び熱源水制御装置
Document Type and Number:
Japanese Patent JP6942575
Kind Code:
B2
Abstract:
To provide a heat source water control method and a heat source water control device capable of reducing power of a heat source machine.SOLUTION: A heat source water control method includes a stop information acquisition step, an operating state acquisition step, a valve opening acquisition step and an operation switching step. In the stop information acquisition step, information on whether a compressor of a heat source machine of which operation is restricted based on a water temperature of heat source water sent from a heat source machine to a use side thermal load is stopped is acquired. In the operating state acquisition step, an operating state of a heat source machine side pump of which rotational frequency is controlled based on the water amount of the heat source water is acquired. In the valve opening acquisition step, a valve opening of a valve for controlling the supply amount of the heat source water to the use side thermal load is acquired. In the operation switching step, the operating state and the stop state of the heat source machine side pump is switched based on whether the compressor is stopped, the operating state of the heat source machine side pump and the valve opening.SELECTED DRAWING: Figure 2
