Abstract:
1. A heat source system comprising: a plurality of heat source apparatuses connected in parallel; and a number-of-units control device that controls on and off of the plurality of heat source apparatuses and allocates a load to an active heat source apparatus according to a load demand, wherein each of the heat source apparatuses is configured to; possess COP information, unique to the respective heat source apparatuses, that indicates a relationship among operating status, coefficient of performance, and load factor, set, at a predetermined timing, an appropriate operating region that is a load region where the coefficient of performance is equal to or more than a predetermined value from the possessed COP information, when an operable region has been set on the basis of devices provided in the heat source apparatus, set a first load region that satisfies both the appropriate operating region and the operable region, and determine whether or not the first load region is narrower than a predetermined region set in advance, and send any of the appropriate operating region when the operable region has not been set, the operable region when the first region is narrower than the predetermined region, and the first load region when the first region is not narrower than the predetermined region to the number-of-units control device at a predetermined timing, and wherein the number-of-units control device performs number-of-units control and load allocation such that each of the heat source apparatuses is operated within the appropriate operating region or the operable region or the first load region which is received from the each of the heat source apparatus.
