BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar device that exchanges heat with solar heat by directly utilizing a roof or the like.

0002

[Prior Art and its Problems] Conventionally, solar devices that exchange heat with solar heat by directly utilizing roofs, etc. include solar systems for hot water supply, snow melting devices, heating devices, and various other devices. known (for example, Japanese Unexamined Patent Application Publication No. 50-139524, Japanese Utility Model Application No. 56-2
(See Publication No. 5125, etc.).

By the way, thermal efficiency, structure, and appearance are important factors that determine the marketability of solar devices. High thermal efficiency is an important element in terms of the performance required of the equipment itself, and a simplified structure helps reduce product and construction costs.Furthermore, appearance has a large impact on the overall design of the house. becomes an important element.

However, in the case of solar devices, thermal efficiency, structure, and appearance are contradictory factors, for example,
In order to increase thermal efficiency, a large amount of insulation material is required, which complicates the structure and increases costs.In addition, if a tiled roof is used for aesthetic reasons, a considerable amount of thermal efficiency must be sacrificed. I don't get it. In the end, there was a problem to be solved in that conventional solar devices could not fully satisfy all of these factors.

[0005] The present invention solves the problems existing in the prior art, and makes it possible to easily apply a solar device to a tiled roof, greatly increase thermal efficiency, and simplify the structure. The purpose is to provide solar equipment that can.

[0006]

[Means for Solving the Problems] The solar device 1 according to the present invention has a plurality of grooves 3 formed at predetermined intervals on the surface 2f of the panel material 2, and inside the grooves 3, It is characterized in that a heat exchange panel section 5 is configured by accommodating heat exchange pipes 4 through which a heat medium liquid flows, and the upper part of the heat exchange panel section 5 is covered with a transparent roof tile 6.

In this case, the panel material 2 may be an orientated standard board 2a formed by hardening wood fibers such as chips with an adhesive, or a particle board. In addition, the surface 2f of the panel material 2 and the groove 3
...The inside is covered with a heat collecting sheet 7, and this heat collecting sheet 7 is given a predetermined coloring corresponding to the roof tiles, and a transparent sheet (or transparent panel) 8 is placed between the transparent roof tiles 6 and the heat exchange panel section 5. It is desirable to intervene.

[0008]

[Operation] According to the solar device 1 according to the present invention, solar heat passes through the transparent roof tiles 6 and is collected by the heat exchange panel section 5. The collected solar heat is heat exchanged with the heat medium liquid flowing through the heat exchange pipes 4. As a result, the heat transfer liquid is heated.

At this time, the heat exchange panel section 5 is made of orientated standard board 2a or particle board, which has particularly excellent heat insulation properties, and is combined with the heat collecting sheet 7, thereby making it possible to extremely reduce heat loss. Since solar heat transmitted through the transparent roof tiles 6 can be directly utilized, thermal efficiency is dramatically increased and the structure is simplified.

Furthermore, in contrast to the use of transparent roof tiles 6, if the heat collecting sheet 7 is colored in a predetermined color corresponding to roof tiles, an appearance similar to that of a normal tiled roof can be created. Note that the transparent sheet 8 has a waterproof function.

Embodiments Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

First, the structure and construction method of the solar device 1 according to the present invention will be explained with reference to FIGS. 1 to 3.

In FIG. 1, R is the roof of a house, and on the roof board P on the roof R is laid a panel material 2 having a plurality of grooves 3 formed in parallel on the surface 2f at predetermined intervals. . In this case, by oriented the grooves 3 horizontally, it becomes convenient for installing roof tiles, which will be described later. The panel material 2 is an orientated standard board 2a. The board 2a is made by blending wood fibers (waste materials) such as chips in a certain direction and hot-pressing molding with an adhesive such as a thermosetting resin, and has high heat insulation properties, as well as excellent strength and sound insulation properties. Further, it can be formed to any size, for example, a single panel with a side of 10 m or more can be manufactured. Although it is most desirable to use the orientated standard board 2a, particle board may be used instead. Particle board is basically the same as Orientate Standard Board 2a, but Particle Board is formed by hardening sawdust, chips (smaller than the chips of Orientate Standard Board 2a), etc. with adhesive.

[0014] Then, the surface 2f of the panel material 2 and the groove 3
...The inside is covered with a heat collecting sheet 7. The heat collecting sheet 7 is colored in a predetermined color corresponding to roof tiles, and for example, any color can be selected such as graphite color for Japanese tiles, brownish or blueish for Western style tiles.

Further, 4 is a heat exchange pipe, and grooves 3...
Two pieces (generally more than one piece) on the heat collecting sheet 7 inside
The pipe bodies 4a and 4b are housed side by side. The heat exchange pipe 4 is for circulating a heat medium liquid (water, antifreeze, etc.) and is made of synthetic rubber or the like. The heat exchange pipe 4 is shown in Figure 2.
As shown in , one end thereof is connected to a supply side main pipe 21 arranged on one side of the panel material 2, and the other end is connected to a discharge side main pipe 22 arranged on the other side of the panel material 2, By bending the end of the groove 3 into a U shape and storing it in the next groove 3, it is arranged in an S-shape so as to be continuous with the three grooves 3. Construction of such heat exchange pipes 4 is performed sequentially in the grooves 3 . Note that the color of the heat exchange pipe 4 is the same as that of the heat collection sheet 7.
It is desirable to match the coloring of As described above, the heat exchange panel section 5 is configured.

Furthermore, the upper surface of the heat exchange panel section 5 is covered with a transparent sheet 8 made of synthetic resin.
Transparent roof tiles 6 made of tempered glass or the like are sequentially laid on top of the tiles. The transparent sheet 8 improves waterproofness and heat retention, and may be a transparent panel or the like that partially covers the transparent sheet 8 if necessary.

Next, a method of using the solar device 1 according to the present invention will be explained with reference to FIG.

FIG. 4 shows a floor heating system 30. As shown in FIG. Reference numeral 31 denotes a heat panel for floor heating, which is basically constructed in the same manner as the heat exchange panel section 5 described above. The supply side main pipe 32 of the heat panel 31 is connected to the output port 34z of the three-way switching valve 34 via the pump 33. Further, one input port 34x of the three-way switching valve 34 is connected to the discharge side main pipe 22 of the heat exchange panel section 5, and the other input port 34y of the three-way switching valve 34 is connected to the discharge port of the boiler 35. do. The suction port of the boiler 35 and the supply side main pipe 21 of the heat exchange panel section 5 are connected to the return side main pipe 36 of the heat panel 31. Note that FIG. 4 shows a basic circuit, and various other necessary circuit components are connected.

Therefore, if antifreeze liquid as a heat transfer liquid is stored in the circuit and the three-way switching valve 34 is switched to put one input port 34x and one output port 34z in a flowing state, the heat transfer liquid will flow through the heat exchange panel section 5. At the same time, the heated heat medium liquid is exchanged with solar heat and supplied to the heat panel 31 via the three-way switching valve 34 and the pump 33, thereby performing floor heating. The heat-exchanged heat medium liquid is then returned to the heat exchange panel section 5 again. Note that by switching the three-way switching valve 34, the output port 34z and the other input port 34
If y is placed in a flowing state, a normal floor heating system that can utilize the heat medium liquid heated by the boiler 35 can be configured.

In addition, by circulating water through the heat exchange panel section 5, a water heater using a normal solar system can be constructed. Furthermore, if the heat exchange panel section 5 is attached only to the roof on the south side, and the heat panel 31 is attached to the roof on the north side,
It can be configured as a snow melting device, and can especially melt snow that is difficult to melt on the north roof. In addition, it can be used for various purposes such as supplying hot water to heat storage tanks and indoor heating other than floor heating.

The embodiments have been described in detail above, but
The invention is not limited to such embodiments. For example, although a separate panel material such as an orientated standard board is used as the panel material, this panel material may also be a board material that directly constitutes the roof, such as a roofing board. Further, it may be applied to the entire surface of the roof or only to a part of the surface. In addition, the detailed configuration, shape, direction, quantity, material, etc. may be arbitrarily changed without departing from the gist of the present invention.
