Abstract
A superordinate controlling device for a heat source system (1) including a plurality of heat sources, the superordinate controlling device being applied to the heat source system (1) and controlling heat-pump type chillers (2a) and (2b) and absorption-type chillers (2c) and (2d) in such a manner that a heat transfer medium leaving temperature that is the temperature of a heat transfer medium supplied to an external load (6) is equal to a setting temperature. The heat-pump type chillers (2a) and (2b) each have a higher Coefficient of Performance (COP) than that of each of the absorption-type chillers (2c) and (2d). The superordinate controlling device includes a heat transfer medium leaving temperature changing means for carrying out heat transfer medium leaving temperature control, by changing the heat transfer medium leaving temperatures of the heat-pump type chillers (2a) and (2b), when a post-change prediction value of each of the absorption-type chiller (2c) and (2d) predicted based on a supposition that the heat transfer medium leaving temperatures of the heat-pump type chillers (2a) and (2b) are changed exceeds a second underload stop threshold value at which the correspondi…
