In the above-described heat medium supply device, the heat source and each panel are connected while the supply state of the heat medium can be adjusted for each panel according to the situation in the space to be cooled and heated. It is preferable that a pipe space such as a pipeline to be reduced can be reduced, and that a construction work can be easily performed. That is, in the heat medium supply device as described above, the supply state of the heat medium can be adjusted for each panel, the piping space is reduced, and
Three factors that facilitate construction work are desired.

However, in the conventional heat source supply device,
The supply state of the heat medium can be adjusted for each panel,
None of the three elements of reducing the piping space and facilitating the construction work could be realized, and at least one of the three elements was missing. That is, the heat medium supply device using the configuration described in Japanese Utility Model Publication No. 55-17057 cannot adjust the supply state of the heat medium for each panel.
In the heat medium supply device shown in FIG. 9, the number of pipes between the heat source and each panel is twice as large as the number of panels, so that not only the piping space is increased, but also the heat medium supply forward path and the heat medium reduction Each of the return trips must be connected to each panel,
The construction work may be complicated. Further, in the heat medium supply device illustrated in FIG. 10, it is necessary to connect each of the branch reduction paths in the heat medium supply outward path and the heat medium reduction return path to each panel, and there is a concern that the construction work may be complicated. .

Then, as shown in FIG. 11, a supply header 28 and a reduction header 29 are provided, and the heat source 21 and the supply header 28 are connected by a single heat medium supply outward path 23 to reduce the heat.
