HEAT SOURCE SYSTEM CONTROL DEVICE, HEAT SOURCE SYSTEM, HEAT SOURCE SYSTEM CONTROL METHOD, AND HEAT SOURCE SYSTEM CONTROL PROGRAM

WIPO Patent Application WO/2018/066357

A1

A high-level control device for a heat source system (1) that is applied to the heat source system (1) comprising a plurality of heat sources and that controls a heat pump refrigerator (2a, 2b) and an absorption refrigerator (2c, 2d) so that the temperature at a heating medium outlet, which is the temperature of a heating medium to be supplied to an external load (6), is at a set temperature, wherein a heating medium outlet temperature changing means is provided to perform heating medium outlet temperature control to change the heating medium outlet temperature of the heat pump refrigerator (2a, 2b) when the predicted post-change value of the absorption refrigerator (2c, 2d) exceeds a second light load stop threshold, which is a light load stop for the absorption refrigerator (2c, 2d), assuming that the coefficient of performance (COP) of the heat pump refrigerator (2a, 2b) is higher than that of the absorption refrigerator (2c, 2d) and that the heating medium outlet temperature of the heat pump refrigerator (2a, 2b) has changed.
