From the cooling water pipeline L4 of 0, another pipeline L12 (second piping system) branches to join the hot water from the heating heat exchanger 16 to the hot water pipeline L5 that supplies the heating load 18. In terms of
This is different from the prior art of FIG. Further, in FIG. 1, the cold water pipe L3 for supplying the cold water of the absorption refrigerator 10 to the cooling load 12 is connected to the low temperature water pipe (denoted by L2 in FIG. 5) for supplying the low temperature water of the CGS2 to the radiator 7.

An on-off valve V13 is provided at 3. Further, an opening / closing valve V14 and an opening / closing valve V15 are installed in the cooling water pipeline L4 and the second piping system L12 of the absorption refrigerator 10, respectively, and the hot water pipeline L5 and the second piping system L12 An on-off valve V16 is provided in the middle of the confluence.

The high temperature water of CGS2 flowing in via the three-way valve V1 acts as a high temperature heat source of the heat pump. Further, the low temperature water of CGS2 introduced through the first piping system L10 acts as a low temperature heat source as described above. And the absorption refrigerator 1
As described above, the cooling water of 0 is supplied to the heating side (the heat exchanger 16 for heating, the hot water pipe line L5, the heating load 8) as the medium-temperature water through the second piping system L12. FIG. 3 shows this relationship in terms of heat quantity.
