At present, outside of the fields related to the results of use of the technology, the equipment for making it, the collection and transportation of trash generated by the operation of equipment, and the recycling field for efficiently reusing those trash. There are no unrelated technical fields, including new fields that cannot be imagined.

(Point of interest)
In the general floor heating system that has been adopted so far, multiple floor heating panels with piping grooves recessed in the top wall of the unit panel made of heat insulating material are the targets of floor heating of buildings. It is laid on the floor base of the floor area, and the hot water circulation pipe is accommodated along the piping groove, and the high thermal conductivity of aluminum sheet, copper sheet, etc. is placed on the top wall of the floor heating panel including the hot water circulation pipe. The heat equalizing sheet is laid in a laminated manner, the floor finishing material for floor heating is laminated on the upper surface of the heat equalizing sheet, and hot water is circulated in the hot water supply pipe of the hot water supply device (heat medium fluid supply device) installed outside the building. The pipes are connected, but in this way, multiple floor heating panels can be installed without error while checking the arrangement of the piping grooves for the floor area to be heated. The work of laying the pipes for hot water circulation along the pipe grooves and laying the heat soaking sheet and floor finishing material after laying them in combination is complicated and laborious, and is faster, more accurate, and more economical. It was quite difficult to do.

(Conventional technology)
Proposals that reflect this situation and provide a solution to it are not unheard of.
For example, as typified by the one proposed in Patent Document 1 (1) below, the panel main body is configured such that the front surface material, the substrate, and the back surface material are integrally laminated and can be joined adjacent to each other. It consists of a (unit panel) and a hot water circulation pipe (floor warming supply pipe) housed in a concave groove (piping path) for piping formed inside the board, and the hot water circulation pipe (floor warming supply pipe) is the panel body. The communication connection part extends from the adjacent surface of the (unit panel), and the groove width is widened so that the communication connection part can be stored in the concave groove (pipe path) for piping, and the panel main body is provided. The hot water circulation pipe (floor warming supply pipe) that connects (unit panels) can be stored inside the panel body (unit panel), so the panel body (unit panel) can be placed directly on the floor base without the need for roots, etc. There are known floor heating panels and floor heating panel construction methods that can fix the pipes, make the construction easier, and shorten the construction time.

Further, in Patent Document 1 (2), a plurality of parallel linear concave grooves (pipe paths) as hose storage portions are formed on the upper surface of the panel (unit panel), and the concave grooves (pipe paths) are formed. It has a heat medium flow pipe (floor warming supply pipe) to be arranged, and for the heat medium flow pipe (floor warming supply pipe), a supply pipe and a return pipe are provided from a boiler (heat medium fluid supply device) via a hose header. A connected floor heating system is shown, and further, a rectangular substrate (unit panel) having a groove (pipe passage) for accommodating pipes on the upper surface, which is seen in Patent Document 1 (3), is shown. A group of multiple boards (folding panel for floor heating) arranged in an aggregated manner, and a temperature control pipe (floor warming supply pipe) housed in a groove and continuously routed to an adjacent board (unit panel). ), And there are some foldable panels for floor heating that can be bent so that the upper surface side is folded in a valley at the long side of the board (unit panel).

Although the floor heating panels as shown in the former Patent Documents 1 (1) to 1 (3) have the advantages of reducing the construction manpower and being able to be installed more economically. When hot water (heat medium fluid) supplied from the hot water supply device (heat medium fluid supply device) flows into the floor warming supply pipe laid along the piping path recessed in the top wall of the unit panel, The fluid flows and dissipates at a substantially constant flow velocity, and in order to uniformly heat the entire surface of the unit panel, the hot water must be circulated at the highest possible flow velocity, and the hot water must be circulated as the flow velocity increases. As the amount of circulation increased, the amount of fuel consumed also increased, and there was a problem that not only the heating was uniform over the entire surface but also the financial burden increased.

(Problem awareness)
As described above, all of the various floor heating panels, etc., which have been proposed so far and are heated by receiving the heat medium fluid from the heat medium fluid supply device, are recessed in the top wall of the unit panel. It is assumed that the floor warming supply pipe is arranged in the groove (pipe path), which greatly improves the construction efficiency, but it does not mean that the utility cost required for floor heating can be significantly reduced. When the supply amount of the heat medium fluid supplied from the heat medium fluid supply device is reduced in an attempt to reduce the fuel consumption, the flow velocity of the heat medium fluid flowing through the floor warming supply pipe is reduced, and the downstream of the floor warming supply pipe is reduced. There remains a fatal drawback that the temperature of a part of the top wall of the unit panel drops, resulting in a floor heating system with uneven heating, and the heat medium supplied from the heat medium fluid supply device remains. Even when the amount of fluid supplied is reduced, the flow velocity of the heat medium fluid flowing through the floor heating supply pipe does not decrease, and the entire top wall of the unit panel can be heated uniformly. I became keenly aware of the need for further improvement in the configuration of the floor heating supply pipe to be combined with it.

(Purpose of Invention)
Therefore, the present invention remarkably improves the storability, transportability, and construction workability of the floor heating panel itself before construction so that it can be installed more economically, and the heat supplied from the heat medium fluid supply device. Even when the amount of medium fluid supplied is reduced, the flow velocity of the heat medium fluid flowing through the floor heating supply pipe is maintained high, and the entire top wall of the unit panel can be heated more uniformly, making it more economical to use. Judging that it would be possible to develop a new floor heating technology that was made possible, we quickly started the development and research, and as a result of repeating long-term trial and error and numerous trials and experiments, this time we finally finally New structure floor heating panel, new structure floor heating foldable panel, new structure floor heating supply pipe used for them, new structure floor heating panel unit incorporating them, and them We have succeeded in realizing a floor heating system having a new structure using the above, and in the following, the configuration will be described in detail together with examples representing the present invention shown in the drawings.

Since the flow velocity of the fluid is further increased, the heat medium fluid flows at high speed over almost the entire surface of the unit panel, the temperature unevenness can be significantly reduced, and more uniform floor heating can be realized, and the central pipe. Therefore, the flow velocity of the heat medium fluid that joins the mainstream return pipe having an inner diameter larger than that of the central pipe is reduced, and flows from the downstream end of the mainstream return pipe into the return pipe of the heat medium fluid supply device having an inner diameter larger than that of the mainstream return pipe.
