<P>PROBLEM TO BE SOLVED: To appropriately diffuse heat from a heat storage unit according to the level of demand for output of heat to the heat storage unit, thereby preventing insufficient output of heat or excessive output of heat from the heat storage unit. <P>SOLUTION: The switching to flow cooling water selectively to a plurality of passages 4a and 4b corresponding to a plurality of compartments 5a and 5b formed in the heat storage unit 5 is performed by a switching valve 11, a first cutoff valve 12, and a second cutoff valve 13. In addition, the heat storage unit 5 is formed such that each of the plurality of compartments 5a and 5b has a different coefficient of heat transfer from a heat storage material 6 to the cooling water becomes different. Furthermore, the switching of passages is conducted by the switching valve 11, the first cutoff valve 12, and the second cutoff valve 13 according to the level of demand for output of heat, such as hot heat or cold heat, to the heat storage unit 5. This allows for appropriate diffusion of heat in just proportion from the heat storage unit 5 according to the demand for the heat storage unit 5 for output of the heat. <P>COPYRIGHT: (C)2013,JPO&INPIT |
