Description

  The present invention relates to a heat storage panel having a latent heat storage material.

  In recent years, research and development to make more effective use of thermal energy generated during indoor heating and natural energy such as solar radiation in the technical field of building materials such as wall materials, floor materials, and ceiling materials from the viewpoint of environmental performance Is actively engaged in, and energy conservation and ecological measures are taken based on these research and development.

  In view of these points, heat storage panels using heat storage materials have been developed for wall materials, floor materials, ceiling materials, and the like. Here, as a heat storage material, a latent heat storage material capable of storing heat at a temperature equal to or higher than the melting point (phase change temperature) has been attracting attention, and various heat storage panels using the latent heat storage material have been proposed.

  As such a technique, for example, Patent Document 1 proposes a heat storage panel in which a porous material is impregnated with a molten mixture of an ethylene-α-olefin copolymer and a crystalline organic compound (latent heat storage material). . According to this heat storage panel, since the latent heat storage material is impregnated in the porous material together with the ethylene-α-olefin copolymer, the leakage of the latent heat storage material from the porous material can be reduced.

JP-A-5-001281

  However, even when the heat storage panel shown in Patent Document 1 is used, it is impossible to completely prevent the latent heat storage material from seeping out from the heat storage panel when the latent heat storage material is melted. Therefore, before the heat storage panel is directly fixed to the installation surface such as the wall surface, the entire surface of the heat storage panel is often covered with a sheet material.

  Even if such measures are taken, when the heat storage panel is fixed to the installation surface with a fixing tool such as a nail, the fixing tool penetrates the heat storage panel together with the sheet material. Thereby, it is assumed that the molten latent heat storage material leaks out or volatilizes from the through-hole formed by the fixture, and the heat storage performance of the heat storage panel is lowered.

  This invention is made in view of such a point, and even if it fixes to an installation surface with a fixing tool, the thermal storage panel which can prevent that thermal storage performance falls by the leakage or volatilization of a latent heat storage material. Is to provide.

  In view of the above problems, the heat storage panel according to the present invention is a heat storage panel having a latent heat storage material, and is formed around an impregnation portion in which a porous base material is impregnated with the latent heat storage material, and the impregnation portion. A fixing member through which a fixing tool for fixing the heat storage panel to the installation surface penetrates, a surface of the impregnation portion, and a surface of the impregnation portion from both sides of the panel material And a sheet material covering at least the surface of the fixed portion, wherein the heat storage panel is configured to block the latent heat storage material from the impregnation portion toward the fixing portion.

  According to the present invention, since the latent heat storage material is impregnated in the impregnation part of the heat storage panel, the heat input to the heat storage panel can be stored by the latent heat storage material and can be dissipated. Here, since the latent heat storage material heading from the impregnation portion to the fixing portion is blocked, the latent heat storage material melted in the impregnation portion does not go to the fixing portion. Therefore, even if a fixing tool is passed through the fixing part of the heat storage panel and the heat storage panel is fixed to the installation surface, the latent heat storage material of the impregnation part may leak or volatilize from the through hole formed in the fixing part by the fixing tool. There is no. As a result, it is possible to prevent a decrease in the heat storage performance of the heat storage panel fixed to the installation surface.

  As a more preferable aspect, the fixing part is impregnated with a portion of the porous substrate impregnated with a thermosetting resin or a thermoplastic resin having a melting point higher than the phase change temperature of the latent heat storage material. Part.

  According to this aspect, a part of the porous base material corresponding to the fixing part is impregnated with the thermoplastic resin having a melting point higher than the phase change temperature of the thermosetting resin or the latent heat storage material. It is possible to block the latent heat storage material from the part toward the fixed part. Thereby, even if the heat storage panel is fixed to the installation surface with a fixing tool, the latent heat storage material in the impregnation portion does not leak or volatilize from the through hole of the fixing portion. In addition, since the fixing portion is impregnated with resin in the porous base material (the edge thereof), the strength can be increased as compared with the case of only the porous base material.

  In another preferred embodiment, the fixing portion is a frame body that surrounds the periphery of the impregnation portion so as to hold the impregnation portion, and the impregnation portion is interposed between the impregnation portion and the fixing portion. A blocking member that blocks the latent heat storage material facing the fixed portion is disposed.

  According to this aspect, the latent heat storage material directed from the impregnation portion to the fixing portion can be interrupted by the blocking member disposed between the impregnation portion and the fixing portion. As a result, the latent heat storage material in the impregnation part does not leak or volatilize outside even if the fixing tool is passed through the frame that is the fixing part and the heat storage panel is installed on the installation surface. Moreover, since the latent heat storage material which goes to a fixed part from an impregnation part can be interrupted | blocked by the interruption | blocking member, the raw material of a frame is not limited.

  As another more preferable aspect, the fixing portion is a nonporous frame body that surrounds the periphery of the impregnation portion so as to hold the impregnation portion. According to this aspect, by making the fixing portion a non-porous frame, it is possible to block the latent heat storage material from the impregnation portion toward the fixing portion. As a result, the latent heat storage material in the impregnation part does not leak or volatilize outside even if the fixing tool is passed through the frame that is the fixing part and the heat storage panel is installed on the installation surface. When manufacturing a panel material, an impregnated panel in which a porous base material is impregnated with a latent heat storage material may be assembled to a non-porous frame, so that a heat storage panel is easily manufactured compared to other embodiments. be able to.

Fig.1 (a) is a typical disassembled perspective view of the thermal storage panel 1 which concerns on 1st Embodiment of this invention, FIG.1 (b) is AA arrow directional cross-sectional view of Fig.1 (a). is there.

1. About heat storage panel 1 As shown in Drawing 1 (a) and Drawing 1 (b), heat storage panel 1 concerning this embodiment is independent as building materials which constitute parts of buildings, such as a floor, a ceiling, a roof, an inner wall, and an outer wall. By using in combination with other building materials, heat storage properties are imparted to this part. The heat storage panel 1 has a panel shape (board shape), and the heat storage panel 1 shown in FIG. 1A has a rectangular shape in a plan view. The shape is not particularly limited, such as a square shape, a circular shape, an elliptical shape, or a polygonal shape.

  As shown to Fig.1 (a), the thermal storage panel 1 is provided with the panel material 2 and a pair of sheet | seat materials 4 and 4 which cover the panel material 2 from both sides. In the present embodiment, the panel material 2 includes an impregnation portion 21 in which a porous material is impregnated with a latent heat storage material, and a fixing portion 22 formed around the impregnation portion 21. As will be described later, the fixing portion 22 is a portion through which a fixing tool 70 such as a nail or a screw for fixing the heat storage panel 1 to the installation surface 7a such as the column 7A or the intermediate column 7B passes. In this embodiment, as will be described later, the impregnation portion 21 and the fixing portion 22 are formed from a single plate-like porous base material.

  Here, although the thickness of a porous base material is not specifically limited, Usually, it is 3-30 mm, Preferably it is 5-20 mm. In this embodiment, the impregnated portion 21 of the porous base material is impregnated with a latent heat storage material, and the fixing portion 22 has a latent heat storage material in the portion of the porous base material around the impregnation portion 21. It is impregnated with a thermosetting resin that has been heat-cured or a thermoplastic resin having a melting point higher than the phase change temperature of the latent heat storage material. Note that “impregnated with a thermoset resin that has been thermoset” means that the void of the porous base material is impregnated with an uncured thermoset resin and then thermoset. I mean. Although it is preferable that the impregnation part 21 is entirely impregnated with the latent heat storage material over the thickness direction of the porous base material, it is not limited thereto, and only the surface layer portion of the porous base material is included. The latent heat storage material may be impregnated.

  If the porous base material is made of a material having fine voids that can be impregnated and held with the latent heat storage material, and can be impregnated with the latent heat storage material of the impregnation portion 21 and the resin of the fixing portion 22, The material is not limited.

  Examples of the material for the porous substrate include wood boards such as particle boards (PB) and wood fiber boards (MDF, insulation boards, hard boards, etc.). Other examples include inorganic boards such as gypsum board and calcium silicate board, mineral boards in which mineral substances are formed into a board shape, boards that accumulate inorganic fibers such as glass wool, carbon fiber, or metal fibers. Can do.

The latent heat storage material impregnated in the impregnation unit 21 is, for example, a latent heat storage material that changes phase from a solid phase to a liquid phase by heating in a room, heat from sunlight, or the like, and preferably has a phase change temperature of 18 ° C to 30 ° C It is a latent heat storage material in the range. Specific examples include sodium sulfate hydrate, calcium chloride hydrate, paraffin (for example, C ₁₈ H ₃₈ ), polyethylene glycol (molecular weight 500 to 1000) sodium sulfate decahydrate, and the like. The material is not particularly limited as long as it can store heat at a temperature or higher.

  In addition to this, the latent heat storage material impregnated in the impregnation part 21 may be a latent heat storage material that is in a gel state at a phase change temperature or higher. Since the solid state changes to the gel state above the phase change temperature, the shape of the latent heat storage material can be easily maintained even when the phase change temperature is exceeded. Examples of such a latent heat storage material include a latent heat storage material MHSR series manufactured by Mitsubishi Cable Industries, Ltd.

  Further, for example, as disclosed in International Publication No. 2015/174523 filed by the applicant, a heat storage material composition containing a predetermined hydrogenated styrene-based thermoplastic elastomer in the latent heat storage material is applied to the panel material 2. It may be impregnated. Examples of the hydrogenated styrene thermoplastic elastomer include styrene-ethylene / butylene-styrene block copolymer (SEBS), styrene-ethylene / propylene block copolymer (SEP), styrene-ethylene / propylene-styrene block copolymer ( SEPS), and at least one selected from the group consisting of styrene-ethylene-ethylene / propylene-styrene block copolymer (SEEPS) (may be a mixture of two or more).

  As shown in FIG. 1A and FIG. 1B, in this embodiment, the fixing portion 22 surrounds the impregnation portion 21 over the thickness direction of the panel material 2, and from the impregnation portion 21 to the fixing portion. 22 is a member configured to block the latent heat storage material toward 22. Specifically, in this embodiment, as described above, the fixing portion 22 is a portion in which the edge of the porous base material is impregnated with a thermosetting resin so as to surround the impregnation portion 21, or a latent heat storage material. This is a portion impregnated with a thermoplastic resin having a melting point higher than the phase change temperature.

  The resin impregnated in the fixing portion 22 is preferably a thermoplastic resin that does not soften when the heat storage panel 1 is used, and is a thermoplastic resin that does not soften at 120 ° C. or higher or a thermosetting resin (after curing). For example, examples of such a thermoplastic resin include polypropylene resin, polyethylene resin, polyvinyl chloride resin, polycarbonate resin, nylon resin, polyethylene terephthalate resin (PET resin), and the like. Examples of the thermosetting resin include phenol resin, urea resin, melamine resin, epoxy resin, saturated polyester resin, and acrylate resin.

  Here, in the present specification, “configured to block the latent heat storage material from the impregnation portion toward the fixing portion” means that the fixing portion 22 cannot impregnate the latent heat storage material, or is fixed to the impregnation portion 21. It means both the state where the movement of the latent heat storage material from the impregnation part 21 to the fixed part 22 is blocked by the blocking member between the part 22 and the part 22. In the present specification, an example corresponding to the former described above is disclosed in the present embodiment, and third and fourth embodiments described later, and an example corresponding to the latter described above is disclosed in the second embodiment.

  In this embodiment, the panel material 2 includes an impregnation portion 21 in which a central portion of one porous base material is impregnated with a latent heat storage material, and an edge portion of the porous base material so as to surround the impregnation portion 21. Since the fixing portion 22 impregnated with the above-described resin is included, the impregnation portion 21 and the fixing portion 22 are flush with each other. Therefore, a sheet material 4 to be described later can be easily joined (attached) to the surface of the panel material 2.

  The sheet material 4 covers the surface 21 a of the impregnating part 21 and the surface 22 a of the fixing part 22 adjacent to the surface 21 a of the impregnating part 21 from both sides of the panel material 2. The thickness of the sheet material 4 is usually 20 to 400 μm, preferably 50 to 200 μm.

  The sheet material 4 is joined to the surface 21 a of the impregnation part and the surface 22 a of the fixing part 22. In the present embodiment, the sheet material 4 is bonded to the surface 21a of the impregnated portion 21 and the surface 22a of the fixed portion 22, but the surface of the fixed portion 22 is bonded by bonding the surface 22a of the fixed portion 22 with the sheet material 4. If the latent heat storage material of the impregnation part 21 does not flow out between the sheet material 4 and the sheet material 4, the sheet material 4 may be bonded to the surface 22 a of the fixed part 22 without being bonded to the impregnation part 21.

  The material of the sheet material 4 is not particularly limited as long as the material has a melting point higher than that of the latent heat storage material and does not transmit the latent heat storage material. Examples of the material for the sheet material 4 include thermoplastic resins such as polypropylene resin, polyethylene resin, polyvinyl chloride resin, polycarbonate resin, nylon resin, polyethylene terephthalate resin (PET resin), and sheets made of these materials. A metal sheet or film such as an aluminum foil may be further laminated on the material, or a metal sheet or film may be interposed as an intermediate layer of a plurality of sheet materials.

  In the present embodiment, the sheet material 4 is directly joined to the surface 21 a of the impregnation part 21 and the surface 22 a of the fixing part 22 by hot pressure described later. As apparent from the manufacturing method described later, in the heat storage panel 1 according to the present embodiment, a part of the thermoplastic resin of the surface layer of the sheet material 4 is impregnated in the voids of the porous base material constituting the panel material 2. ing. Thereby, the sheet material 4 can be firmly joined to the panel material 2. Moreover, in this embodiment, since the sheet | seat material 4 and the surface 21a of the impregnation part 21 are joined, it is hard to form a clearance gap between these. Therefore, the molten latent heat storage material hardly stays between the sheet material 4 and the impregnation portion 21.

  In the present embodiment, the thermoplastic resin is exemplified as the material of the sheet material 4. However, for example, the sheet material 4 may be made of a metal sheet or film such as aluminum. In this case, an adhesive resin is interposed between the sheet material 4 and the panel material 2. As an adhesive resin, any resin of a thermoplastic resin or a thermosetting resin may be used as long as these bonds are maintained and solidified (cured) after hot pressing described later.

2. FIG. 2A is a schematic perspective view for explaining a method of attaching the heat storage panel 1 shown in FIG. 1A as a wall material between the pillars 7A and 7B.

It attaches using the fixing tools 70, such as.

  Specifically, from the front side of the heat storage panel 1, the front end of the fixture 70 is passed through the front side sheet material 4, the fixed part 22 of the panel material 2, and the back side sheet material 4 in order, Embedded in 7A or stud 7B. Thereby, the thermal storage panel 1 is fixed between the column 7A and the inter-column 7B.

  According to this embodiment, since the latent heat storage material is impregnated in the impregnation part 21 of the panel material 2 of the heat storage panel 1, the heat input to the heat storage panel 1 is stored with the latent heat storage material, and this is dissipated. Can do.

  Here, since the fixing part 22 is impregnated with a thermosetting resin or a thermoplastic resin having a melting point higher than that of the latent heat storage material, the latent heat storage material from the impregnation part 21 toward the fixing part 22 is fixed. The portion 22 is not impregnated. That is, the latent heat storage material from the impregnation portion 21 toward the fixing portion 22 is blocked by the fixing portion 22.

  Therefore, even if the fixture 70 is passed through the fixing portion 22 of the heat storage panel 1 and the heat storage panel 1 is fixed to the installation surface 7 a, the latent heat of the impregnation portion 21 from the through hole formed in the fixing portion 22 by the fixture 70. The heat storage material does not leak or volatilize. As a result, it is possible to prevent a decrease in the heat storage performance of the heat storage panel 1 fixed to the installation surface 7a. Further, since the fixing portion 22 is impregnated with the above-described thermosetting resin or thermoplastic resin, the strength can be increased as compared with the case of the non-impregnated one.

Each through hole 41 is formed at a position corresponding to the fixing portion 22 of the panel material 2, and the fixing portion 22 is exposed from the through hole 41. In this embodiment, as shown to Fig.9 (a), the through-hole 41 is formed so that the through-hole 41 formed in each sheet material 4 may correspond along the thickness direction of the thermal storage panel 1. As shown in FIG. Yes.

  According to the heat storage panel 1 according to the present embodiment, as shown in FIG. 9B, each through hole 41 is used as a mark for fixing the heat storage panel 1, not on the impregnated portion 21 of the panel material 2 but on the fixing portion 22. The heat storage panel 1 can be fixed between the pillars 7A and the intermediate pillars 7B by penetrating the fixture 70.

  Since the through holes 41 of the sheet materials 4 are formed in the thickness direction of the heat storage panel 1 through which the fixing tools 70 penetrate, the fixing tools 70 are inserted into the through holes 41 of the sheet material 4 on the back side of the heat storage panel 1. It is inserted. As a result, when fixing the heat storage panel 1, the sheet material 4 on the back surface side (the column 7 </ b> A or the intermediate column 7 </ b> B side) is not lifted by the fixture 70. Property (adhesiveness) can be maintained.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs can be made without departing from the spirit of the present invention described in the claims. It can be changed.

  For example, in the present embodiment, a sheet material having the same size as the surface of the panel material is prepared, and the sheet material is joined to the frame. However, if the impregnated portion can be covered with the sheet material, the size of the sheet material is It may be smaller than the size of the sheet material in the form.

  Further, the structure of the sheet material according to the fourth embodiment may be applied to the sheet material according to the second or third embodiment.
