Description

  The present invention relates to a heat storage system provided in a building such as a house, and a building provided with the heat storage system.

Conventional heating appliances that operate with energy sources such as electricity, oil, and gas have a problem that costs increase as these energy sources are used. Therefore, in recent years, technology for floor heating with a solar heat storage system is known. (See Patent Document 1).

JP-A-6-34205

  However, in the technique of Patent Document 1 described above, since air heated by solar heat is guided to the floor and the heat storage material cannot be stored unless the heat of the air is absorbed, for example, the heat storage material itself is directly subjected to solar heat. Compared with the case where the heat is stored and stored, it takes time and may not be efficient.

  An object of the present invention is to provide a heat storage system and a building capable of efficiently storing solar heat in a latent heat storage material and capable of forming a comfortable living environment.

The invention according to claim 1 is a heat storage system provided in a building 1 such as a house as shown in FIGS.
While being installed in a place that receives solar heat (for example, roof 2), a heat storage unit 11 for storing heat in the latent heat storage material 10,
The heat dissipating part 12 is disposed on the back side of the finishing materials 3a, 4a, 6a such as the wall surface 3 or the floor surfaces 4, 6 and emits heat stored in the latent heat storage material 10 transferred from the heat storage part 11. When,
Circulating means for circulating the latent heat storage material 10 between the heat storage unit 11 and the heat radiating unit 12 is provided.

According to the invention described in claim 1, heat can be stored in the latent heat storage material 10 at the heat storage section 11 installed at the location (for example, the roof 2) that receives the solar heat, and the stored latent heat storage material is stored. 10 can be transferred to the heat radiating part 12 by the circulation means, and the latent heat storage is performed by the heat radiating part 12 installed on the back side of the finishing material 3a, 4a, 6a such as the wall surface 3 or the floor surfaces 4, 6 and the like. The heat stored in the material 10 can be released, and the latent heat storage material 10 that has released the heat can be transferred to the heat storage unit 11 by the circulation means. As a result, it is possible to omit the process of absorbing the heat to the heat storage material after the air heated by the solar heat is bothered to the floor under the conventional method, so that heat is stored in the latent heat storage material 10. Time until the stored heat is radiated at a predetermined location can be shortened, and the efficiency is high.
Further, the latent heat storage material 10 can absorb and release a large amount of heat when a phase change is performed at a preset temperature. Heat that is higher than the air temperature and room temperature can be released from the wall surface 3 and the floor surfaces 4, 6 and the like, and in warm seasons such as summer, the temperature is lower than the outside air temperature and the room temperature due to radiant cooling at night. Heat can be released from the wall surface 3, the floor surfaces 4, 6, and the like. And since such a latent heat storage material 10 can be efficiently stored and circulated as described above, a comfortable living environment can be formed.

The invention according to claim 2 is the heat storage system according to claim 1, for example, as shown in FIGS.

It is provided in the vicinity of the outlet of the heat radiating section 12 through which the latent heat storage material 10 passes, and has an opening / closing section 16 that opens and closes the outlet of the heat radiating section 12.

According to the invention described in claim 2, the circulation between the heat storage unit 11 and the heat radiating unit 12 of the latent heat storage material 10 is performed by appropriately operating the transfer unit 14 and the opening / closing units 15 and 16. It will be possible to control. That is, for example, when circulating the latent heat storage material 10, when opening and closing the outlets of the heat storage unit 11 and the heat radiating unit 12 by the opening and closing units 15, 16 or when storing heat in the latent heat storage material 10, When the outlet of the heat storage unit 11 is closed by the opening / closing unit 15 or when the latent heat storage material 10 is radiated by the heat dissipation unit 11, the outlet of the heat dissipation unit 12 is blocked by the opening / closing unit 16. The circulation between the heat storage part 11 and the heat radiation part 12 of the latent heat storage material 10 can be suitably controlled.
Thus, for example, when heat dissipation is required, the transfer means 14 and the opening / closing parts 15 and 16 are operated to transfer the latent heat storage material 10 from the heat storage part 11 to the heat dissipation part 12. When the heat dissipation is no longer necessary, the transfer means 14 and the opening / closing sections 15 and 16 are operated to transfer the latent heat storage material 10 from the heat dissipation section 12 to the heat storage section 11. Therefore, the latent heat storage material 10 can be optionally circulated, and a more comfortable living environment can be formed.

The circulation means is provided in the vicinity of the inlet of the heat radiating section 12 through which the latent heat storage material 10 passes, and includes an opening / closing section 17 that opens and closes the inlet of the heat radiating section 12.

  According to the third aspect of the present invention, the circulation between the heat storage unit 11 and the heat dissipation unit 12 of the latent heat storage material 10 can be controlled by appropriately operating the opening / closing unit 17. That is, when the latent heat storage material 10 is transferred to the heat radiating unit 12, the opening / closing unit 17 is opened, and when the latent heat storage material 10 is not transferred to the heat radiating unit 12, the opening / closing unit is used. 17 can be closed. Thus, for example, there are a plurality of rooms in the building 1, and among these rooms, heat radiation is installed on the back side of the finishing material 3a, 4a, 6a such as the wall surface 3 or the floor surfaces 4, 6 of one room. The latent heat storage material 10 is transferred to the section 12, and the latent heat storage material 10 is disposed on the heat radiating section 12 installed on the back side of the finishing materials 3a, 4a, 6a such as the wall surface 3 or the floor surfaces 4, 6 of the other room. It is possible to cope with the case where 10 is not transferred.

As a result, when the granular latent heat storage material 10 is transferred from the heat storage unit 11 through the passage 13 to the heat radiating unit 12 by the air ejected from the blower 14 or from the heat radiating unit 12, for example. When passing through the passage portion 13 and transferring to the heat storage portion, air inside the heat storage portion 11, the heat radiating portion 12, and the passage portion 13 can be discharged from the discharge portion 11d. An air flow when circulating the heat storage material 10 can be formed, and the granular latent heat storage material 10 can be easily transferred.
Moreover, since the said discharge part 11d is a mesh-shaped surface material which has a mesh smaller than the particle size of the said granular latent heat storage material 10, the said granular latent heat storage material 10 will be discharged | emitted from this discharge part 11d.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 to 7, the heat storage system according to the present embodiment is provided in a building 1 such as a house, and is installed in a location that receives solar heat, and stores heat in the latent heat storage material 10. The heat storage unit 11 and the finishing material 3a, 4a, 6a such as the wall surface 3 or the floor surfaces 4, 6 are installed on the back side, and the heat stored in the latent heat storage material 10 transferred from the heat storage unit 11 is released. And a circulating means for circulating the latent heat storage material 10 between the heat storage unit 11 and the heat dissipation unit 12.

  The building 1 such as a house according to the present embodiment includes a building main body 1a constructed on an upper portion of the foundation 1b. The building main body 1a such as the roof 2, the walls 3, and the floors 4 and 6 of the building main body 1a. It is constructed by a panel method in which components are panelized at the factory in advance and these panels are assembled and constructed at the construction site, but the conventional shaft construction method and wall construction method such as wooden, steel structure, reinforced concrete construction, etc. It can also be applied to buildings.

  Although not shown in the figure, this panel is assembled into a rectangular shape with vertical and horizontal saddles, and an auxiliary saddle member is vertically and horizontally assembled inside a rectangular frame to form a frame, and both sides of the frame or A face material is affixed to one side and has a hollow structure inside. Furthermore, a heat insulating material such as glass wool or rock wool is usually loaded into the hollow interior portion.

Here, the latent heat storage material 10 can absorb or release a large amount of heat when a phase change is performed at a preset temperature.
This phase change includes a phase change between gas and liquid, a phase change between liquid and solid, a phase change between gas and solid, a phase change in crystal structure, etc. Since it is easy to handle when a phase change between a solid and a solid is used, it is often used. The phase change from the liquid to the solid is called solidification, and the phase change from the solid to the liquid is called melting. Usually, the solidification temperature at which solidification occurs and the melting temperature at which liquefaction are substantially the same. Moreover, the solidification temperature which solidifies and the melting temperature which liquefies may differ.

  Examples of such latent heat storage material 10 include calcium chloride hexahydrate, sodium sulfate decahydrate, sodium acetate trihydrate, paraffins, fatty acid esters, aliphatic alcohols, olefin resins, and the like. Since these latent heat storage materials become liquid above the melting temperature (solidification temperature), it is preferable to use them in a sealed container.

  Furthermore, since the temperature at which the latent heat storage material 10 undergoes a phase change varies depending on the selection of each latent heat storage material, it is necessary to select it appropriately. Further, the amount of stored heat is also appropriately selected because it varies depending on each latent heat storage material.

In the present embodiment, as shown in FIGS. 5 and 6, one of these latent heat storage materials (for example, paraffin) is used as a core material, and this core material is covered with a polymer. The latent heat storage material 10 is formed by using a large number of granular latent heat storage materials formed into microcapsules.
In addition, since the latent heat storage material 10 is a large number of granular latent heat storage materials 10 in this way, the surface area is larger than, for example, a heat storage material formed in a sheet shape or the like, so that the amount of stored heat can be increased. There are advantages.

  In addition, when the core material of the latent heat storage material 10 is paraffin as described above, when setting the phase change temperature depending on the melting temperature and the solidification temperature, a wide temperature range (−50 ° C. to 80 ° C.) corresponding to the number of carbon chains. Can be covered, and the amount of heat storage is relatively large, which is preferable.

  In addition, although the latent heat storage material 10 of this Embodiment was made into many granular latent heat storage materials 10, it is not restricted to this, For example, it is liquid like the latent heat storage materials, such as a paraffin, disperse | distributed in water and emulsified. It may be a latent heat storage material. In the case of a liquid latent heat storage material, it is easy to circulate between the heat storage unit 11 and the heat radiating unit 12, and furthermore, if a pump is used, the liquid latent heat storage material is easily and reliably pumped, and the liquid latent heat storage material is transferred to the heat storage unit. 11 and the heat dissipating part 12 can be circulated. Further, the circulation path when the liquid latent heat storage material circulates between the heat storage unit 11 and the heat radiation unit 12 needs to be sealed.

  In the present embodiment, one type of latent heat storage material 10 whose phase change temperature is set to a predetermined temperature is used. However, the latent heat storage material set to a phase change temperature different from this latent heat storage material 10 is used. A material may be used. That is, a plurality of latent heat storage materials having different phase change temperatures may be used to configure a heat storage system that responds more specifically to changes in air temperature or seasonal changes.

On the other hand, as shown in FIGS. 1 to 6, the heat storage unit 11 is installed at a location that receives solar heat, and stores heat in the latent heat storage material 10.
Locations that receive solar heat include, for example, the outer surface of the roof 2 (roof panel 2) and the wall 3 (wall panel 3), and the floors 4 and 6 (floor panels 4 and 6) in the building body 1a where the sunlight is inserted. In this embodiment, it is assumed that it is installed on the roof panel 2.

  Further, as shown in FIG. 5 and FIG. 6, the heat storage unit 11 is provided on the roof panel 2, the installation unit 11 a on the installation unit 11 a, on the side, and the like, and in a vertical and horizontal grid pattern. This is a so-called glass module including the assembled frame 11b and a translucent member 11c such as glass held by the frame 11b. When storing heat in the latent heat storage material 10, the latent heat storage material 10 is retained in a hollow portion surrounded by the installation portion 11a, the frame 11b, and the translucent member 11c. Thus, the latent heat storage material 10 can absorb the heat of the air heated by solar heat so that the heat can be stored.

  For example, while suppressing the height of the hollow part of the said heat storage part 11, ie, the height from the installation part 11a to the translucent member 11c, the installation area of this heat storage part 11 is expanded, The said latent heat storage material 10 is expanded. Is stored in the hollow part of the heat storage part 11 in a shallow and wide space, which is preferable because heat can be efficiently stored.

  In addition, such a heat storage part 11 shall be comprised by dividing a hollow part into plurality, for example. That is, it can respond to the case where the heat radiating section 12 is provided in each of a plurality of rooms in the building main body 1a, or can correspond to the case where a plurality of latent heat storage materials having different phase change temperatures are used for each season.

On the other hand, as shown in FIGS. 1 to 4 and 7, the heat radiating portion 12 is installed on the back side of a face material (finishing material 3 a, 4 a, 6 a) such as a wall panel 3 or a floor panel 4, 6. The heat stored in the latent heat storage material 10 transferred from the heat storage unit 11 is released.
In the present embodiment, it is assumed that the heat radiating portion 12 is installed on the back side of the face material (finishing materials 4a, 6a) attached to the upper surfaces of the floor panels 4, 6.

  The heat dissipating part 12 has a hollow part whose size is set in accordance with the size of the room on the floor panel 2 and the latent heat transferred from the heat accumulating part 11 in the hollow part. The heat storage material 10 is retained, and the retained latent heat storage material 10 releases heat, whereby the temperature of the underfloor space can be increased and the room floor can be heated.

  In addition, for example, by increasing the area of the heat radiating unit 12, the floor heating area of the room can be increased. Moreover, since the said latent heat storage material 10 will be laminated | stacked highly by making the height of the hollow part of the said thermal radiation part 12 high, long-time temperature stabilization can be achieved and it is preferable.

  On the other hand, as shown in FIGS. 1 to 4 and 7, the circulation means connects the heat storage part 11 and the heat dissipation part 12, and the passage part 13 through which the latent heat storage material 10 passes, and the passage part. 13 and is provided in the vicinity of an outlet of the heat storage unit 11 through which the latent heat storage material 10 passes and a transfer means 14 that transfers the latent heat storage material 10 along the passage portion 13. 11 is provided in the vicinity of the outlet of the heat dissipating part 12 through which the latent heat storage material 10 passes, and the opening / closing part 16 opens and closes the outlet of the heat dissipating part 12.

  The passage portion 13 has a pipe shape that connects the heat storage portion 11 and the heat dissipation portion 12. It is desirable that such a passage portion 13 does not appear in a portion where a resident in the building body 1a is active.

  Further, the transfer means 14 is provided in the middle of the passage portion 13. Specifically, the latent heat storage material 10 is disposed on the inlet side and the outlet side of the heat radiating unit 12 and below the floor panel 4 and falls from the heat storage unit 11 through the passage unit 13. Can be transferred into the heat radiating section 12 by the transfer means 14 on the inlet side, and the latent heat storage material 10 that needs to store heat is transferred to the heat storage section 12 by the transfer means 14 on the outlet side. Can do.

  In addition, since the latent heat storage material 10 of this Embodiment is many granular latent heat storage materials 10 as mentioned above, the transfer means 14 of this Embodiment is the air for transferring the said granular latent heat storage material 10 A blower 14 is used. The granular latent heat storage material 10 can be easily and reliably transferred by the air ejected from the blower 14.

Further, when the large number of granular latent heat storage materials 10 are transferred by the blower 14 as described above, the heat storage unit 11 discharges the air ejected from the blower 14 to the outside of the building 1 as shown in FIG. It is desirable to have a discharge part 11d for this purpose.
Thereby, when passing from the heat storage part 11 to the heat dissipation part 12 through the passage part 13 or when transferring from the heat dissipation part 12 to the heat storage part through the passage part 13, Since the air inside the heat storage unit 11, the heat radiating unit 12, and the passage unit 13 can be discharged from the discharge unit 11 d, it is possible to form an air flow when circulating the granular latent heat storage material 10, It becomes easy to transfer the granular latent heat storage material 10.

  Further, a mesh-shaped face material having a mesh smaller than the particle diameter of the granular latent heat storage material 10 is used for the discharge portion 11d, and the granular latent heat storage material 10 is discharged from the discharge portion 11d. Can be surely prevented.

  On the other hand, the opening / closing parts 15 and 16 are, for example, dampers, and can open and close the outlet of the heat storage part 11 and the outlet of the heat radiating part 12 by rotating the shaft as shown in FIGS. 1 to 4 and 7. It is like that. In addition, the open / close sections 15 and 16 can close the outlets of the heat storage section 11 and the heat dissipation section 12 in an airtight manner.

And the circulation between the said heat storage part 11 of the said latent heat storage material 10 and the thermal radiation part 12 can be controlled by operating the above transfer means 14 and the opening-and-closing parts 15 and 16 suitably.
That is, for example, when circulating the latent heat storage material 10, when opening and closing the outlets of the heat storage unit 11 and the heat radiating unit 12 by the opening and closing units 15, 16 or when storing heat in the latent heat storage material 10, When the outlet of the heat storage unit 11 is closed by the opening / closing unit 15 or when the latent heat storage material 10 is radiated by the heat dissipation unit 11, the outlet of the heat dissipation unit 12 is blocked by the opening / closing unit 16. The circulation between the heat storage part 11 and the heat radiation part 12 of the latent heat storage material 10 can be suitably controlled.
Thus, for example, when heat dissipation is required, the transfer means 14 and the opening / closing parts 15 and 16 are operated to transfer the latent heat storage material 10 from the heat storage part 11 to the heat dissipation part 12. When the heat dissipation is no longer necessary, the transfer means 14 and the opening / closing sections 15 and 16 are operated to transfer the latent heat storage material 10 from the heat dissipation section 12 to the heat storage section 11. Therefore, the latent heat storage material 10 can be optionally circulated.

  Moreover, in this Embodiment, these transfer means 14 and the opening-and-closing parts 15 and 16 are controlled by the control apparatus which is not shown in figure. The control device includes a remote controller disposed in the building main body 1a so that a resident can operate the transfer means 14 and the opening / closing sections 15 and 16 while in the room. To do.

On the other hand, as shown in FIG. 7, the circulating means is provided in the vicinity of the inlet of the heat radiating portion 12 through which the latent heat storage material 10 passes, and includes an opening / closing portion 17 that opens and closes the inlet of the heat radiating portion 12.
The opening / closing part 17 is also a damper, similar to the opening / closing parts 15 and 16, and is controlled by the control device.

And by operating this opening-and-closing part 17 suitably, the circulation between the said heat storage part 11 and the thermal radiation part 12 of the said latent heat storage material 10 can be controlled.
That is, when the latent heat storage material 10 is transferred to the heat radiating unit 12, the opening / closing unit 17 is opened, and when the latent heat storage material 10 is not transferred to the heat radiating unit 12, the opening / closing unit is used. 17 can be closed.
Accordingly, for example, a room on the floor panel 6 in FIG. 7 is provided in the building main body 1a separately from the room on the floor panel 4 in FIGS. 1 to 4, that is, a plurality of rooms are provided in the building main body 1a. Of these plural rooms, the latent heat storage material 10 is transferred to the heat radiating section 12 installed on the back side of the finishing material 4a (6a) such as the floor panel 4 (6) of one room, and the other It is also possible to cope with the case where the latent heat storage material 10 is not transferred to the heat radiating section 12 installed on the back side of the finishing material 6a (4a) such as the floor panel 6 (4) of the room.

  1 to 4 and the floor panel 6 in FIG. 7 are arranged at different heights, and a room or the like is provided above and below the floor panel 6 in FIG. Yes. By providing the heat dissipating part 12 at the lower part of the floor panel 6, the heat dissipating part 12 can radiate heat to the room above or below the floor panel 6.

On the other hand, the end of the floor panel 4 of the building main body 1a is placed on the foundation 1b as shown in FIGS. 1 to 4, and the foundation 1b has an inner peripheral surface of the foundation 1b. A heat insulating material 1 c is provided, and the floor panel 4 is provided with a heat insulating material 4 b only at an end portion of the floor panel 4.
Thereby, it is possible to prevent the heat released from the heat radiating part 12 installed on the back side of the finishing material 4a of the floor panel 4 from being released to the outside from the ends of the foundation 1b and the floor panel 4. it can. Thereby, the heat radiation from the heat radiation part 12 into the building body 1a can be promoted.
