  Next, a method for manufacturing the hot water type floor heating panel 1 having such a structure will be described.

  First, the components (the aluminum plate 3, the aluminum vapor deposition paper 5, the medium specific gravity fiber board 9, the hot water pipes 6, 7, etc.) of the hot water type floor heating panel 1 are prepared.

  Here, since the hot water pipe 6 and the hot water pipe 7 have the same shape as each other as described above, it is sufficient to make one type, and productivity is improved.

  Finally, flip the whole over and flip it upside down.

  Here, the hot water type floor heating panel 1 is completed, and the manufacturing process of the hot water type floor heating panel 1 is completed.

  And when using this hot water type floor heating panel 1, first, the predetermined number of hot water type floor heating panels 1 are constructed according to the area to be heated, and two of these hot water type floor heating panels 1 are used. The hot water pipes 6 and 7 are connected in series. Then, end portions 6a and 7a on the inlet side of the hot water pipes 6 and 7 of the first hot water type floor heating panel 1 and end portions 6b and 7b on the outlet side of the hot water pipes 6 and 7 of the last hot water type floor heating panel 1 are connected.

Thus, the weight can be significantly reduced. As a result, the workability and handling properties of the hot water floor heating panel 1 can be improved, and the construction period can be shortened.

  Furthermore, in the hot water type floor heating panel 1, since the medium specific gravity fiber board 9 is attached to the back surface of the aluminum plate 3, a floor finishing material (not shown) such as flooring is provided on the upper side of the hot water type floor heating panel 1. When constructing, the floor finish is firmly fixed to the hot water floor heating panel 1 by driving a nail through the floor finishing material and the medium specific gravity fiber board 9 of the hot water floor heating panel 1. Can do.

  Moreover, this hot water type floor heating panel 1 has a panel body 2 having a thickness T1 of 12 mm, that is, the same thickness as the plywood frequently used for the floor base material, so that the workability of the hot water type floor heating panel 1 is improved. To do.

  In addition, since this hot water type floor heating panel 1 uses a heat pump 11 as a hot water supply source, it uses environmental heat such as heat in the air, leading to energy saving, reducing carbon dioxide gas, and global warming. Help prevent.

Moreover, in the hot water type floor heating panel 1, since the two hot water pipes 6 and 7 are both made of copper, they are not only robust and durable but also have an antibacterial effect on hot water. Furthermore, recycling at the time of disposal is also possible.
[Embodiment 2 of the Invention]

  3 and 4 show a second embodiment of the present invention.

  As shown in FIGS. 3 and 4, the hot water floor heating panel 1 according to the second embodiment is larger in size (width W1) than the hot water floor heating panel 1 according to the first embodiment described above. The length of the panel body 2 is reduced to a square plate (specifically, the panel body 2 has a width W1 of 600 mm, a length L1 of 600 mm, and a thickness T1 of 12 mm). And the shape of the two hot water pipes 6 and 7 are changed (specifically, the hot water pipe 6 is formed in a substantially U shape having a curved portion 6c having a small curvature). At the same time, the hot water pipe 7 is formed in a substantially U shape having a curved portion 7 d having a large curvature, and the curved portion 7 d of the hot water pipe 7 is disposed inside the curved portion 6 c of the hot water pipe 6. And two hot water pipes 6 7 on the outlet side of the end portion 6b, except that attached U-tube (pipe joint) 8 detachably to 7b, has the same structure as the first embodiment described above. In addition, about the member same as Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  Therefore, in this hot water type floor heating panel 1, if the U-shaped tube 8 is not used, the size (width W1 and length L1) of the panel body 2 is reduced by 2 as compared with the first embodiment described above. Although the lengths of the hot water pipes 6 and 7 are shortened, they have basically the same configuration, so the same effects as in the first embodiment (mainly the two hot water pipes 6 and 7 The pressure loss resistance can be reduced by supplying warm water in parallel flow.

  When using this hot water type floor heating panel 1, first, a predetermined number of hot water type floor heating panels 1 are constructed according to the area to be heated, and two of these hot water type floor heating panels 1 are used. The hot water pipes 6 and 7 are connected in series. However, as for the hot water type floor heating panel 1 that is turned up, as shown by solid lines in FIGS. 3 and 4, the U-shaped tubes 8 are attached to the end portions 6 b and 7 b on the outlet side of the two hot water pipes 6 and 7. . Then, in this hot water type floor heating panel 1, since the two hot water pipes 6 and 7 are connected to each other via the U-shaped tube 8, the hot water from the heat pump 11 is supplied to the inlet side of one hot water pipe 6. After flowing from the end portion 6a and being supplied through the predetermined hot water pipe 6 to the end portion 6b on the outlet side, the end portion 7b on the outlet side of the other hot water pipe 7 is passed through the U-shaped pipe 8. After being supplied through the hot water pipe 7 in the reverse direction along the predetermined piping path, that is, in a counterflow, it flows out from the end 7a on the inlet side. As a result, in all the hot water type floor heating panels 1, it is possible to supply the hot water supplied from the heat pump 11 in a counterflow.

  In addition, when the size of the panel main body 2 is small, the length of the hot water pipes 6 and 7 can be shortened, so that the temperature difference (temperature gradient) between the inlet and outlet of each hot water pipe 6 and 7 is inevitably small. Therefore, even if the two hot water pipes 6 and 7 are connected to one by the U-shaped tube 8, the panel main body 2 can be warmed almost evenly.

Thus, since this hot water type floor heating panel 1 is equipped with the two hot water pipes 6 and 7 and the detachable U-shaped tube 8, according to the construction situation of the hot water type floor heating panel 1, etc. Hot water can be supplied in either parallel flow or counterflow.
