Description

  The present invention relates to a building including a floor heating device and a solar house that uses solar heat as a heat source of the floor heating device.

  Conventionally, as shown in FIG. 6, the liquid is heated by heating means such as a latent heat storage material 101 (for example, polyethylene glycol) disposed below the flooring 100 and a solar heat collector (not shown). For example, Patent Document 1 describes a building including a floor heating device having a heat medium W and a heat radiating pipe 102 that supplies heat to the latent heat storage material 101 through the heat medium W.

  The latent heat storage material 101 of this floor heating device uses the latent heat that accompanies the phase change to absorb the heat of the heat radiating pipe 102 when the phase changes from a solid to a liquid, and stores the heat, while the temperature drops and the solid from the liquid When the phase changes, the floor material 100 is heated and the flooring 100 is warmed, and a substantially constant temperature can be maintained during heat storage and heat dissipation.

Microfilm of Japanese Utility Model Sho 62-89087 (Japanese Utility Model Sho 63-198922)

The conventional floor heating apparatus described above has a heat insulating material 104, sand 105 through which the heat radiating pipe 102 passes, a metal plate 106, and the latent heat storage material 101 in a concrete frame 103 from below. The concrete floor material 100 is installed on the latent heat storage material 101.
Therefore, a conventional general building structure, that is, a large pull, which is a square member, is hung between square bases attached to the foundation, and a joist, which is also a square member, in a direction perpendicular to the large pull on the large pull. It is not compatible with the general building structure in which a floorboard is placed on the joists. For this reason, experience accumulated over a long period from design to construction is hardly utilized, and much of the design process and execution process can be wasted.

  The present invention has been made in view of the above, and an object thereof is to make a floor heating device compact by effectively utilizing the space between the draws and the joists while inheriting the conventional general building structure. Is to provide buildings and solar houses that can be embedded.

Further, the radiation pipe is disposed on the upper surface of the latent heat storage material, and the upper periphery of the radiation pipe A building provided with a floor heating device, characterized in that a metal tape is attached to the upper surface of the latent heat storage material so as to straddle the surface, and a heat radiation pipe is fixed to the upper surface of the latent heat storage material. .

In addition, as described in claim 2, the heat radiating pipe passes through a side position near the joist of the latent heat storage material, and is folded back into a U shape at an end portion of the latent heat storage material so as to be located at the opposite side position near the joist. And then, it is turned back into a U-shape at the opposite end of the latent heat storage material and moved to the next latent heat storage material sandwiching the joists, so that a plurality of rows of latent heat storage are obtained as a whole by repeating the above piping mode. To meander along the material,
Further, the U-shaped folded-back portion protrudes outward from the end portion of the latent heat storage material to be exposed on the partition plate, and a fixing bracket is fitted to the outer periphery of the exposed portion, and the fixing bracket A building provided with a floor heating device according to claim 1, wherein the building is hit or screwed to the partition plate with a nail member.

  Moreover, as described in Claim 3, the building provided with the floor heating apparatus according to Claim 1 or 2 includes a solar house that includes a heat collector for collecting solar heat in the heating means of the heat medium. provide.

  In the building of the present invention, a partition plate is provided between the upper drawing and joists located above and below, and the space between the large draws on the back side of the partition plate is used as a heat insulating layer, while between the joists on the front side of the partition plate Since the latent heat storage material and the heat radiating pipe are installed in the space of the room and the top is covered with the flooring, it is possible to incorporate the floor heating device compactly by using the space above and below the partition plate added to the conventional general building structure. it can. Therefore, since the experience accumulated from the design of the building to the construction can be fully utilized, the design and construction cost can be saved, and the reliability supported by the past construction results can be secured.

  In addition, since the heat radiating pipe is connected between the latent heat storage material and the floor material, heat can be stored in the latent heat storage material after heat dissipation while heating the floor material directly through the heated liquid heat medium. Then, if the floor heating is performed and the heat medium heated from the next morning after the latent heat storage material has finished radiating, the floor heating can be continued without any break. By the way, when the latent heat storage material is arranged between the flooring and the heat radiating pipe as in the conventional floor heating device described above, even if the heat medium heated in the state where the latent heat storage material is cooled is passed through the heat radiating pipe, Since heat storage to the latent heat storage material is given priority, sufficient heating cannot be performed for a while.

  Further, the heat radiation pipe is arranged in a meandering manner as in claim 2, and the stability of the heat radiation pipe is increased by attracting the U-shaped folded portion and fixing the metal fitting to the partition plate. The stability of the latent heat storage material is also improved.

  Moreover, since the heating means of the heat medium as described in claim 3 includes a heat collector that collects solar heat and uses solar heat, floor heating and heat storage can be performed in parallel with solar heat during the day. 24 hours seamless floor heating can be realized.

It is a longitudinal cross-sectional view of the principal part which shows a prior art.

The floor heating device and the structure of the building according to the embodiment will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the building includes a wooden base 3 mounted on a concrete base 1 via a base packing 2, and a number of large pulls 4 spanned between the bases 3. A wooden partition plate 5 struck so as to cover the upper surface of the large pull 4, a large number of joists 6 laid horizontally in the direction perpendicular to the large pull 4 on the front side of the partition plates 5, and the joists 6 And a wooden flooring 7 that is struck in a state of covering the upper surface.

The base 3, the draw 4 and the joist 6 are wooden squares as is well known. As shown in FIG. 4, the joist 6 uses a square member slightly shorter than the length of the heating area, and a communication passage 8 is formed at one end of the heating area.
The floor material 7 is a two-layer structure in which a floor material 7b is stacked on a floor base material 7a. Of course, the floor material 7 may be one sheet or a plurality of sheets.

  A heat insulating material 10 made of, for example, polystyrene foam is fitted into the space 9 between the large pulls 4 on the back side of the partition plate 5 with almost no gap. Therefore, even if cold outside air flows under the floor through the gap formed by the foundation packing 2 interposed between the foundation 1 and the base 3, the thick heat insulating material 10 makes it difficult for the cold air to be transmitted into the room.

  On the other hand, in a space 11 between the joists 6 on the front side of the partition plate 5, a heat radiating pipe 12 through which a liquid heat medium W (for example, antifreeze) heated by a heating means such as a boiler or solar heat is passed, and the heat radiating pipe And a latent heat storage material 13 for storing the heat supplied from 12 is incorporated.

  The latent heat storage material 13 is made by filling, for example, polyethylene glycol, sodium sulfate or the like in a flat container 13a made of a synthetic resin, and generates heat when the phase changes from a solid to a liquid using the latent heat accompanying the phase change. It absorbs and stores heat, while it dissipates heat when it changes phase from liquid to solid. The horizontal width of the flat container 13 a of the latent heat storage material 13 is set to be approximately the same as the interval between the joists 6, so that the latent heat storage material 13 is completely contained in the space 11 between the joists 6. One latent heat storage material 13 has a length shorter than the total length of the space 11 of the joists 6, and a plurality of latent heat storage materials 13 are arranged in one row of spaces 11. Folding spaces 14 for the heat radiating pipe 12 are provided at both ends.

  The heat radiating pipe 12 is a pipe made of synthetic resin such as polybden, for example, and both ends thereof are connected to a delivery pipe 15a of the heating unit 15 described later. The heat radiating pipe 12 is folded in a U shape in a folded space 14 provided at the end of the latent heat storage material 13 through a side position closer to the joist 6 of the latent heat storage material 13 as shown in FIGS. Through the opposite side of the joist 6 on the opposite side of the latent heat storage material 13 and folded back into a U-shape in the turn-back space 14 provided at the opposite end of the latent heat storage material 13. It moves to the adjacent latent heat storage material 13 which pinched the joist 6 through the channel | path 8, and it is made to meander along all the latent heat storage materials 13 of several rows as a whole by repeating such a piping aspect. In addition, when the floor area is large, if one heat radiating pipe 12 is used, the temperature difference between the start end side and the terminal end side of the heat radiating pipe 12 becomes large, and temperature spots may occur in the room. Divide the floor into a plurality of regions (for example, divide into two at the center of the floor), branch the heat radiating pipe 12 by the number of regions, meander the heat radiating pipe 12 branched in each region, and finally You may make it join the heat radiating pipe 12. By doing so, temperature spots are less likely to occur even in a large room.

  The heat radiating pipe 12 is attached to a top surface of the latent heat storage material 13 with a metal tape 17 (for example, an aluminum tape) so as to straddle the upper peripheral surface thereof, and thus attached to the top surface of the latent heat storage material 13 in a contact state. In this way, the heat of the heat radiating pipe 12 is efficiently transferred to the latent heat storage material 13 via the metal tape 17 by sticking the heat radiating pipe 12 to the upper surface of the latent heat storage material 13 with the metal tape 17 excellent in heat conduction. .

The U-shaped folded portion 12a of the heat radiating pipe 12 is pushed outward from the end of the latent heat storage material 13 using the folded space 14, and is thus exposed on the partition plate 5 and A curved portion 18a of a substantially Ω-shaped fixing bracket 18 is fitted to the outer periphery of the exposed portion, and both side wing pieces 18b, 18b of the fixing bracket 18 are screwed to the partition plate 5 by a nail member 19 which is a wood screw. is there.
The outer diameter of the heat radiating pipe 12 is so large that its upper portion (the heat radiating pipe 12 + the upper portion of the metal tape 17) is close to the lower surface of the flooring 7 in a state where it is fixed to the upper surface of the latent heat storage material 13 with the metal tape 17. Is set.

The building of the present embodiment is configured as described above, and the floor heating apparatus generally includes the heat-dissipating means, the heat-dissipating pipe 12, and the latent heat storage material 13, as well as the large pull 4, the partition plate 5, and the joists 6 that constitute the building. It is formed by a combination of the heat insulating material 10 and the floor material 7.
Then, in the floor heating device, when the heat medium W heated by heating means such as a boiler is passed through the heat radiating pipe 12 in a state where the latent heat storage material 13 has been dissipated and has become solid, the latent heat storage material 13 becomes solid from the solid. When the phase changes to a liquid, the heat of the heat radiating pipe 12 is absorbed and stored, and at the same time, the temperature of the flooring 7 is also increased by the heat of the heat radiating pipe 12. Therefore, the latent heat storage material 13 can also store heat while performing floor heating.
When the heating of the heat medium W by the heating means is stopped, the latent heat storage material 13 dissipates heat when the phase change from liquid to solid, and warms the flooring 7 at a constant temperature for a long time.

  Next, a solar house in which the heating means for supplying the heated heat medium W to the heat radiating pipe 12 is the heat collector 21 that collects solar heat will be described with reference to FIG. In addition, FIG. 5 is a schematic piping diagram of the solar house, and illustration of valves and the like is omitted for convenience of explanation.

  As is well known, the solar house includes a solar heat collecting unit 22, a heating unit 15, and a hot water supply unit 23.

  The solar heat collecting unit 22 is located at a high place (mainly on the roof) of the building and collects solar heat, a liquid storage tank 24 for storing the heat medium W, and the heat collector W by the pump P1. And a recovery pipe 22b for returning the heat medium W from the heat collector 21 to the liquid storage tank 24.

  The heating unit 15 includes the latent heat storage material 13, a heat radiating pipe 12 disposed on the latent heat storage material 13, a delivery pipe 15a for sending the heat medium W to the heat radiating pipe 12 by a pump P2, and a heat radiating pipe 12 And a recovery pipe 15b for returning the heat medium W to the liquid storage tank 24.

  The hot water supply unit 23 includes a hot water storage tank 28 having a heat exchanger 27 therein, an auxiliary boiler 29 for hot water supply, a delivery pipe 23a for sending the heat medium W to the heat exchanger 27, and a pump P3 from the heat exchanger 27. And a recovery pipe 23b for returning the heat medium W to the liquid tank 24.

  In FIG. 5, reference numeral 26 denotes an auxiliary boiler that auxiliaryly heats the heat medium W, reference numeral 26 a denotes a delivery pipe for sending the heat medium W from the liquid storage tank 24 to the auxiliary boiler 26 by the pump P 4, and 26 b denotes a storage from the auxiliary boiler 26. This is a recovery pipe that returns the heat medium W to the liquid tank 24. In FIG. 5, reference numeral 30 denotes a heat medium replenishing port provided in the liquid storage tank 24.

Since the solar house is configured as described above, the heat medium W heated by the solar collector 21 by solar heat can be stored in the liquid storage tank 24.
Then, during the winter day, the heat medium W in the liquid storage tank 24 is supplied to the heating unit 15 to simultaneously store heat in the latent heat storage material 13 and floor heating, and at night, the circulation of the heat medium W is stopped to store the latent heat. Floor heating is performed by heat radiation from the material 13. Here, if the temperature of the heat medium W is not sufficient due to insufficient sunlight, the heat medium W is supplementarily heated by the auxiliary boiler 26.
In addition, the floor heating can be stopped by stopping the circulation of the heat medium W to the heating unit 15 in the season when heating is not required.
On the other hand, since the heat medium W in the liquid storage tank 24 is also used for hot water supply via the hot water supply unit 23, the solar heat collection unit 22 operates throughout the year.

  As apparent from the above description, the floor heating device of the solar house includes the heating unit 15 and the solar heat collecting unit 22.
