<P>PROBLEM TO BE SOLVED: To reduce total energy cost and further to save energy in a heat source system in which equipment having large energy cost per unit heat generation quantity and equipment having small energy cost per unit heat generation quantity are intermixed. <P>SOLUTION: In moderation of a set feed water temperature TSsp, the equipment having large energy cost per unit heat generation quantity takes priority over the equipment having small energy cost per unit heat generation quantity and the set value of outlet temperature of cold and hot water of the equipment having the priority is moderated. For example, when a refrigerating machine 1-1 is defined as a low COP machine (energy cost per unit heat generation quantity is large) and a refrigerating machine 1-2 is defined as a high COP machine (energy cost per unit heat generation quantity is small), the set value TS1sp of the outlet temperature of cold water of the refrigerating machine 1-1 takes the priority over the set value TS2sp of the outlet temperature of cold water of the refrigerating machine 1-2 and is moderated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
