<P>PROBLEM TO BE SOLVED: To provide a heat source system which is more excellent in energy saving and reduction in operation cost. <P>SOLUTION: In the operation of jointly using primary and secondary pumps, the reflux amount of heat medium C from the secondary side outward header H2 to the primary side outward header H1 through a pump bypass path 5 is adjusted by adjusting the opening of a pump bypass valve 5v, thereby, a heat medium supply pressure pm for load equipment U is adjusted to a set supply pressure. In the operation of singly using the primary pump, the pump bypass valve 5v is opened to the full to feed the supply heat medium C by means of the primary pump P1 from the primary side outward header H1 to the secondary side header H2 through the pump bypass path 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
