<p><P>PROBLEM TO BE SOLVED: To provide a heat source water supply system capable of stabilizing a hot water supply amount and a supply temperature, reducing a fuel cost and an operation management cost, suppressing unreasonable generation of carbon dioxide, and suppressing breeding of bacteria. <P>SOLUTION: This heat source water supply system includes a primary hot water supply main pipe 10 from a hot water generator 1 to a hot water storage tank 2, a secondary hot water supply main pipe 11 from the hot water storage tank to a load 3, a circulative return pipe 12 returned from the load 3, and an auxiliary water pipe 13 from a makeup water source 4 to the hot water generator 1 or the hot water storage tank 2. A three-way valve 5 is mounted on the primary hot water supply main pipe 10, a first branch section 7a of a branch section 7 of a composite return pipe 14 is connected to the hot water generator 1, a second branch section 7b of the branch section 7 is connected to the three-way valve 5, the primary hot water supply main pipe 10 is connected to the three-way valve, an injection pipe 15 to the hot water storage tank 2 is connected to the three-way valve, and further a control panel 23 performing detection by a temperature sensor 21 in the hot water storage tank 2, and transmitting control signals to a module 22 of the three-way valve and the hot water generator 1, is disposed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
