<P>PROBLEM TO BE SOLVED: To provide a heat source heat utilizing system capable of preventing temperature rise of a heat medium collected in a heat source and properly cooling the heat source. <P>SOLUTION: This heat source heat utilizing system 20 comprises a first circuit 1 for circulating a first heat medium 4 heated by the heat of the heat source 7, a second circuit 2 comprising a heat load 17 and a thermomotive valve 15 for circulating a second heat medium 5, and a third circuit 3 for circulating a third heat medium 6 capable of exchanging heat with the first heat medium 4 and the second heat medium 5, a first heat exchanger 9 for exchanging heat between the first heat medium 4 and the second heat medium 5, and a second heat exchanger 10 for exchanging heat between the first heat medium 4 and the third heat medium 6 are connected switchably by a switch valve 11 so that the first heat medium 4 exchanges heat with the second heat medium 5 or the third heat medium 6, and further a third heat exchanger 22 is disposed for exchanging heat between the second heat medium 5 and the third heat medium 6. The first heat medium 4 heats the third heat medium 6 when the circulation of the second heat medium 5 is not requested, the third heat medium 6 heats the second heat medium 5 when the circulation of the second heat medium 5 is requested, and the switch valve 11 is switched after the lapse of a prescribed time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
