Description

The present invention relates to a heat storage structure of a building.

The indoor temperature of a building is mainly adjusted by air conditioners (heating equipment, cooling equipment), but in recent years, the power consumption of such air conditioners has been reduced from the viewpoint of energy saving, global warming countermeasures, and running cost reduction. Is required to do.
Therefore, a technique is known in which a latent heat storage material (PCM: Phase Change Material) that utilizes latent heat when a substance undergoes a phase change between a solid phase and a liquid phase is incorporated into the floor of a building to mitigate changes in indoor temperature. (See, for example, Patent Document 1). Specifically, the heat inside the room due to the air conditioner and sunlight is naturally stored by the latent heat storage material so that the room temperature does not change suddenly after the air conditioner is stopped or after sunset.

Japanese Unexamined Patent Publication No. 2013-024001

However, when the heat inside the room is stored by the latent heat storage material, for example, the amount of heat transferred from the room side to the latent heat storage material is not sufficient, or it is affected by the cold air under the floor. Only a narrow area on the indoor side may act to store heat. If only a narrow area on the indoor side acts to store heat in this way, the heat storage time becomes short, and there is a problem that the effect cannot be sufficiently exerted.

The present invention has been made in view of the above circumstances, and is a heat storage structure of a building capable of sufficiently exerting a heat storage effect by preventing only a narrow range on the indoor side of the latent heat storage material from acting and storing heat. The purpose is to provide.

Further, when radiating heat, the heat insulating material 13 makes it difficult to radiate heat to the side opposite to the room, so that more heat stored in the latent heat storage material 42 and the heat storage plate 41 can be radiated to the room side.
Further, since the heat storage plate material 41 is attached to the indoor side surface of the building plate material 12 and the finishing layer 50 is located on the indoor side of the heat storage layer 40, the heat storage plate material 41 is fixed for fixing the finishing layer 50. It can be used as a base.
Further, since the latent heat storage material 42 is in the form of a pack, it is easy to handle and can contribute to the improvement of workability.
Further, since the plurality of recesses 43 in which the latent heat storage material 42 is stored are composed of the plurality of long materials 43a attached to the indoor side surface of the heat storage plate material 41, a storage space for the latent heat storage material 42 can be provided. It can be formed by the heat storage plate material 41, a plurality of long materials 43a, and a finishing layer 50. As a result, a storage space for the latent heat storage material 42 can be secured, and the periphery of the latent heat storage material 42 can be reliably surrounded and protected.
Further, since the finishing layer 50 is supported by the heat storage plate material 41 via the long material 43a, the finishing layer 50 can be supported from the heat storage plate material 41 at intervals of a plurality of long materials 43a. .. As a result, the finishing layer 50 can be reliably fixed to the heat storage plate material 41 via the long material 43a while securing a storage space for the latent heat storage material 42.

That is, the face material 12 of the first building panel 10 in the panel construction method and the fixed base material in the other construction methods are also used as the floor base material.

The heat insulating material 13 is provided on the side opposite to the indoor side of the face material 12, which is a building board material. That is, since the heat insulating material 13 is filled in the inner hollow portion of the first building panel 10 as described above, it is not exposed on the upper surface side (indoor side) of the face material 12.

The heat storage layer 40 located on the upper surface side (indoor side) of the face material 12 in the first building panel 10 is located on the indoor side of the face material 12 which is a building plate material, and has a pack-like shape with the heat storage plate material 41.

Thereby, the heat storage property can be improved at the place where the heat storage plate material 41 is provided. Further, in the present embodiment, a hard gypsum board is usually used as described above, but other high-density board materials such as a hard wood piece cement board may be used. That is, ordinary hard gypsum board, hard wood piece cement board, etc. have a high density, and the higher the density, the higher the heat storage effect. The specific gravity of these ordinary hard gypsum boards and hard wood piece cement boards is set to 0.9 or more.

The latent heat storage material 42 is also called a PCM (Phase Change Material), and utilizes the latent heat when a substance undergoes a phase change from a solid phase to a liquid phase or from a liquid phase to a solid phase. When the temperature of 42 rises and reaches its melting point, the latent heat storage material 42 begins to melt and absorbs the heat of melting from the outside. On the contrary, when the temperature of the latent heat storage material 42 in the liquid phase drops and reaches the freezing point, solidification starts and the heat of solidification is released to the outside. This kind of heat transfer is used.

The latent heat storage material 42 includes, for example, a material obtained by impregnating a carrier which is a porous material such as calcium chloride hydrate or porous silica with normal paraffin or an inorganic hydrate which is a heat storage material, or a capsule of the same heat storage material. And those enclosed in a bag-like body are used.
As the latent heat storage material 42 in the present embodiment, a gel-like heat storage material 42a is enclosed in an aluminum pack 42b which is a bag-like body (see FIG. 3). The latent heat storage material 42 is located on the upper surface side (indoor side) of the heat storage plate material 41.
Since the latent heat storage material 42 is packed in this way, it is easy to handle and can contribute to the improvement of workability.

The plurality of recesses 43 are spaces for accommodating the latent heat storage material 42, and are formed at positions where the latent heat storage material 42 should be provided. More specifically, a plurality of long members 43a are vertically and horizontally attached to the upper surface of the heat storage plate 41, and the upper surface of the heat storage plate 41 is divided into a plurality of sections by the plurality of long members 43a. ing. In other words, a plurality of long timbers 43a are assembled in a grid frame shape to form a plurality of sections, and each of these sections is a recess 43. The latent heat storage material 42 is housed in each of such compartments (recesses 43).
The thickness of the long lumber 43a is not particularly limited, but is set to, for example, about 8 mm, and the depth of the recess 43 also corresponds to the thickness of the long lumber 43a. Therefore, the thickness of the latent heat storage material 42 housed in the recess 43 also corresponds to the thickness of the long material 43a. However, the thickness of the latent heat storage material 42 is set to be slightly thicker than the thickness of the long material 43a so that the latent heat storage material 42 and the finishing layer 50 are in close contact with each other after the floor 2 is constructed. May be good.

The finishing layer 50 located on the upper surface side (indoor side) of the face material 12 in the first building panel 10 is located on the upper surface side (indoor side) of the heat storage layer 40, and includes the base plate material 51 and the finishing material 52. Have.

The base plate material 51 is a plate material that serves as a base for installing the finishing material 52, and for example, a building material such as plywood is used.
The base plate member 51 is placed on and fixed on the upper surface of the plurality of long timbers 43a. In other words, the base plate material 51 and the finishing material 52 located in the upper layer of the base plate material 51 are in a state of being supported by the heat storage plate material 41 via a plurality of long members 43a.

The finishing material 52 is a so-called flooring material, and is fixed to the base plate material 51. That is, the finishing layer 50 has two layers of the base plate material 51 and the plate-shaped finishing material 52, and is excellent in rigidity.
Further, the finishing material 52 may be provided on the base plate material 51 to finish only the first building panel 10 side, or as shown in FIG. 2, the first building panel 10 and the second It may be provided so as to straddle both of the building panels 20 and finish both the first building panel 10 and the second building panel 20.

The second building panel 20 has a frame body 21 composed of vertical and horizontal frame members 21a and auxiliary crosspieces 21b, a face material 22 attached to the upper surface of the frame body 21, and heat insulating material filled in an internal hollow portion. It has a material 23 and.
The second building panel 20 is formed to be thicker than the first building panel 10, so that the height position of the face material 22 is higher than that of the face material 12 in the first building panel 10. It is set.
Further, since the second building panel 20 is formed to be thicker in this way, the thickness of the heat insulating material 23 filled in the internal hollow portion is also set to be thicker than that of the heat insulating material 13 in the first building panel 10. Has been done. Therefore, it has excellent heat insulating properties, and it is difficult for cold air from under the floor to be transmitted to the indoor side.

Further, the lower surface of the first building panel 10 and the lower surface of the second building panel 20 are installed so as to be flush with each other. Therefore, since the thickness of the second building panel 20 is thick, a step is formed between the first building panel 10 and the second building panel 20. In other words, above the first building panel 10, there is a space 14 formed by utilizing the difference in thickness between the first building panel 10 and the second building panel 20.

A second adjusting material 9 parallel to the first adjusting material 8 is provided in a step portion of the space 14 formed between the first building panel 10 and the second building panel 20. Since the second adjusting material 9 is provided at a step portion between the first building panel 10 and the second building panel 20, the second adjusting material 9 is provided on the outer periphery of the building like the first adjusting material 8. It is not provided along the line.
The second adjusting material 9 is set to have a thickness dimension substantially equal to that of the first adjusting material 8. The thickness dimensions of the first adjusting material 8 and the second adjusting material 9 are substantially equal to the dimensions in the stacking direction in the heat storage layer 40 excluding the finishing material 52.

The heat storage layer 40 is provided in the space 14 thus formed by utilizing the difference in thickness between the first building panel 10 and the second building panel 20, except for the finishing material 52 in the finishing layer 50. There is. That is, of the heat storage layer 40 and the finishing layer 50 located on the indoor side of the first building panel 10, the upper surface of the base plate material 51 in the finishing layer 50 and the upper surface of the face material 32 of the second building panel 20 are surfaces. It is in a single state. The upper surfaces of the second adjusting material 9 are also flush with each other.

Then, as described above, the finishing material 52 is provided on the upper surface of the base plate material 51, the upper surface of the face material 32, and the upper surface of the second adjusting material 9. The finishing material 52 is in contact with the inner surface of the wall 3.
When the finishing material 52 is provided on the base plate material 51 to finish only the first building panel 10 side, the finishing material 52 finishes only the second building panel 20 side (Fig.). Not shown.) Is used separately.

Heat on the indoor side due to the air conditioner or sunlight is transferred to the heat storage layer 40 located on the back side of the finishing layer 50 facing the space of the room 1, and the heat storage layer 40 can store this heat. The stored heat is gradually dissipated, but in particular, the room temperature is prevented from suddenly changing due to the heat dissipated after the air conditioner is stopped or after sunset.
Further, the latent heat storage material 42 is provided in a space surrounded by the surroundings, and the area in contact with the air is larger when the latent heat storage material 42 is provided in a space surrounding the room and is closer to the wall or member surrounding the material, for example, than when the latent heat storage material 42 is exposed in a room space or the like. It is small and can store heat effectively. In the present embodiment, since the latent heat storage material 42 is provided between the heat storage plate material 41 and the finishing layer 50, heat can be effectively stored.

As described above, the heat storage structure is incorporated in the floor 2 of the room 1, and the thermal environment in the room 1 is adjusted.

According to the heat storage structure in the present embodiment, it is possible to prevent a situation in which only a narrow range on the indoor side of the latent heat storage material 42 acts to store heat, so that the heat storage effect of the entire heat storage layer 40 can be obtained. Can be enhanced.
That is, even if the volume of the latent heat storage material 42 is increased in order to improve the heat storage property, the increased heat storage property is not necessarily obtained. For example, in the case of an indoor environment where the amount of heat transferred from the indoor side to the latent heat storage material 42 is insufficient or the cold air from the opposite side of the room is affected, only a narrow range on the indoor side of the latent heat storage material 42 is available. It acts and becomes a state where heat is stored. On the other hand, if the heat storage plate material 41 and the latent heat storage material 42 are provided on the indoor side of the face material 12 in the first building panel 10 in which the heat insulating material 13 is provided on the side opposite to the indoor side, the heat storage plate material 41 and the latent heat storage material 42 are provided from the indoor side. Once the heat is transferred to the heat storage plate material 41, heat can be stored in both the heat storage plate material 41 and the latent heat storage material 42, so that only a narrow range on the indoor side of the latent heat storage material 42 acts to store heat. It is less likely that such a situation will occur. Therefore, the heat storage effect of the entire heat storage layer 40 can be enhanced, and the heat storage effect can be sufficiently exerted.
As a result, the power consumption of the air conditioner can be reduced, which can contribute to energy saving, global warming countermeasures, running cost reduction, and the like.

Further, since the heat insulating material 13 is provided on the side of the building board 12 opposite to the room, the heat insulating material 13 makes it less likely to be affected by the cold air from the side opposite to the room.
Further, when radiating heat, the heat insulating material 13 makes it difficult to radiate heat to the side opposite to the room, so that more heat stored in the latent heat storage material 42 and the heat storage plate 41 can be radiated to the room side.

Further, since the heat storage plate 41 is attached to the indoor side surface of the building plate 12 and the finishing layer 50 is located on the indoor side of the heat storage layer 40, the heat storage plate 41 is fixed for fixing the finishing layer 50. It can be used as a base.

Further, since the plurality of recesses 43 in which the latent heat storage material 42 is stored are composed of the plurality of long materials 43a attached to the indoor side surface of the heat storage plate material 41, the storage space for the latent heat storage material 42 can be used for heat storage. It can be formed by the plate member 41, the plurality of long members 43a, and the finishing layer 50. As a result, a storage space for the latent heat storage material 42 can be secured, and the periphery of the latent heat storage material 42 can be reliably surrounded and protected.
Further, since the finishing layer 50 is supported by the heat storage plate material 41 via the long material 43a, the finishing layer 50 can be supported from the heat storage plate material 41 at intervals of a plurality of long materials 43a. .. As a result, the finishing layer 50 can be reliably fixed to the heat storage plate material 41 via the long material 43a while securing a storage space for the latent heat storage material 42.

Further, since the heat storage layer 40 is provided in the space 14 formed by utilizing the difference in thickness between the first building panel 10 and the second building panel 20, the first building panel 10 and the second building The step caused by the difference in thickness from the panel 20 can be effectively used.
Further, if the thick second building panel 20 is configured to include, for example, the heat insulating material 23, a high heat insulating effect can be obtained. Further, since such a second building panel 20 is provided adjacent to the first building panel 10 having a high heat storage effect, both building panels 10 and 20 can alleviate changes in the indoor temperature. You will be able to contribute.

Further, since the face material 12 which is a building board material is a floor base material constituting the floor 2 of the building frame, it is possible to sufficiently exert a heat storage effect on the indoor side of the building board material 12 which is a floor base material. A possible heat storage layer 40 can be formed. Thereby, the change of the room temperature can be mitigated.

Therefore, for example, from the indoor side. Even in an indoor environment where the amount of heat transferred to the latent heat storage material 42 is not sufficient, the heat storage effect can be sufficiently exerted.

[Modification 3]
In the example shown in FIG. 6, the heat storage structure is incorporated in the wall 3 of the building frame.
The wall 3 in this modification is composed of a building wall panel 30, and the building wall panel 30 includes a face material 32 which is a building board material, a frame body 31 to which the face material 32 is fixed, and a frame. It is configured to include a heat insulating material 33 provided between the frame members forming the body 31.
The face material 32, which is a building board, is attached to both the indoor side and the outdoor side of the frame body 31. The outer wall material 35 is provided on the outdoor side face material 32 via the furring strip 34.

A heat storage layer 40 and a finishing layer 50 are provided on the indoor side of such a building wall panel 30.
When the heat storage structure is incorporated in the wall 3, the latent heat storage material 42 in the heat storage layer 40 tends to move downward due to its own weight. Therefore, the thickness of the latent heat storage material 42 is set to be slightly thicker than the thickness of the long material 43a so that the latent heat storage material 42 and the finishing layer 50 are in close contact with each other after the wall 3 is constructed. It is desirable that the latent heat storage material 42 is in a state where it is difficult to move downward. Alternatively, the latent heat storage material 42 may be adhered to the heat storage plate material 41.
Further, the base plate material 51 in this modification is a gypsum board, and the finishing material 52 is a wall cloth.

According to this modification, since the building panel for building the building frame is the building wall panel 30 constituting the wall 3 of the building frame, the heat storage effect is sufficiently provided on the indoor side of the building wall panel 30. The heat storage layer 40 can be formed. Thereby, the change of the room temperature can be mitigated.
