Hi CD en H 2' 3 2 an object of the invention can be to increase the heat storage capacity of the heat storage material, while the PCM material remains stabilised in its position.
These and/or other objects are achieved by A heat 5 storage material, comprising an immobilised phase change material (PCM), wherein the PCM is contained in at least on pouch, comprising at least one substantially flat face.
By this arrangement, the heat storage material can be attached to a building material or structure. Thus the 10 PCM can only be located as a cladding on the outside of the construction material. This provides an improved heat transfer and an improved exposure of the PCM, while the heat storage capacity remains high and while the structural integrity of the construction materials remains intact.
15 The heat storage material can further comprise a first sheet material, a second sheet material, wherein the first sheet material comprises a first portion, wherein the first portion is substantially flat, wherein the first sheet material comprises at least one second portion, wherein the 20 at least one second portion is embossed or thermoformed in order to create a preferably dome shaped chamber which is suitable for containing material, wherein the first portion surrounds the at least one second portion, wherein the capsulated PCM is inserted in the second portion and the 25 second sheet material is configured to cover and seal the first sheet material comprising the at least one second embossed or thermoformed portion, thus forming at least one PCM containing pouch.
Since the obtained pouches are substantially flat 30 on one surface, they can practically be attached to any suitable surface. The attachment can be performed by applying a glue or, alternatively, the heat storage material itself can be provided with an attachment layer.
3
The heat storage material can comprise tear lines in the first portion of the first sheet material and/or the thereto attached first portion of the second sheet material.
Thus the separate pouches can easily be separated, 5 without rupture of the pouches themselves. Additionally, by these perforated lines, the material can be torn in predetermined portions of heat storage material. Thus, the size of the individual portions can be designed and adapted to the specific sizes of the relevant construction material. 10 If for instance a gypsum board is to be provided with the heat storage material, the size of a perforation dye can be adapted such that the width and the length of the heat storage material fits on the gypsum board without leaving uncovered spaces and without extending over the outer edges 15 of the gypsum board.
The pressure of the PCM containing chambers of the heat storage material can be reduced to sub-atmospheric or can even as low as substantially vacuum. By applying a reduced pressure, the shape of the pouches is more stable 20 and the conductive heat transfer can be optimised.
The invention further relates to a method for the manufacture of a heat storage material as described hereinabove, comprising the following steps, to be executed in any suitable sequence: a) providing a first sheet of 25 material; b) vacuum forming or embossing a multitude of dome shaped cups in a first portion of the first sheet material; c) filling the dome shaped cups with an encapsulated phase change material (PCM); d) providing a second sheet of material; e) covering the open sides of the dome shaped cups 30 in the first sheet material with the second sheet material; f) applying a reduced pressure to the sheet materials and the PCM contained therein; g) sealing a second portion of the first sheet material surrounding the dome shaped cups to 4 the second sheet material, such that pouches are formed, with at least one substantially flat surface.
By this method, the heat storage material as above described can be obtained. In order to attach the heat 5 storage material, the substantially flat face of the heat storage material can be provided with an affixing layer. The affixing layer can be covered by a protective covering layer. The protective covering layer can be provided with an embossed pattern. Thus, the protective covering layer can be 10 peeled off more practically.
In order to further elucidate the invention, exemplary embodiments will be described with reference to the drawing. In the drawing:
Figure 1 represents a schematic cross sectional 15 side view of the heat storage material according to a first embodiment of the invention;
Figure 2 represents a schematic perspective view of a heat storage material according to a further embodiment of the invention; 20 Figure 3 represents a schematic perspective view of the lay out of the heat storage material according to figure 2;
Figure 4 represents a schematic perspective view of a continuous strip of heat storage material according to 25 the embodiment shown in figure 2 and
Figure 5 represents a schematic sectional side view of a panel comprising the heat storage material according to the embodiment shown in figures 2-4.
The figures represent specific exemplary 30 embodiments of the inventions and should not be considered limiting the invention in any way or form. Throughout the description and the figures the same or corresponding 5 reference numerals are used for the same or corresponding elements .
The expression "cladding" used herein is to be understood as, though not to be considered limited to a 5 covering or overlaying material or composition, having a two dimensions, a length and a width that are considerably larger that its thickness.
The expression "heat storage material" used herein is to be understood as, though not to be considered limited 10 to a substance or a composition with a relative high heat of fusion or dehydration which, is capable of reversible storing and releasing relative large amounts of energy. By choosing the appropriate composition of the heat storage material, a specific melting/fusion or dehydration 15 temperature or a specific melting/fusion hydration/dehydration temperature range can be obtained. The heat storage capacity of PCM can be up to 14 times the heat storage capacity of conventional building materials such as brick, concrete or wood.
20 The expression "phase change material (PCM)" is to be considered a heat storage material as hereinabove defined.
The latent heat storage in PCM's can be achieved by the heat of transformation from one phase into another.
25 Examples for such phase changes are solid-solid, solid- liquid, solid-gas, liquid-gas and hydrated solid-dehydrated solid and water.
The material can be stabilized by encapsulation such that e.g. the PCM cannot migrate in the molten state or 30 e.g. water cannot escape from a salt hydrate in its dehydrated state. Such materials re e.g. sold under the brand name Thermusol (c) by the company Capzo, based in Ootmarsum (Ov), the Netherlands. These materials are in 6 further detail described in the international application WO-A-2008153378, which is incorporated herein by reference in its entirety.
In figure 1, a cross sectional side view of a 5 detail of a pouch 1 with encapsulated heat storage material 2 is presented. In this figure, the pouch 1 comprises a first sheet material 3 and a second sheet material 4, being sealed or glued together in a first portion 5 of the sheet material 3 and 4 and forming a pouch shaped chamber, in a 10 second portion 6 of the sheet material 3 and 4. In the pouch section 6, an encapsulated phase change material 2 is contained. This van be a heat storage material as is described in WO-A-2008153378.
In figure 2, a band of heat storage material 7, 15 comprising a multitude of pouches 1 is depicted. The band 7 comprises sections 10A-10L, each comprising an array of two pouches 1 wide and 12 pouches tall. In between the sections 10A-10L tear lines 8 and 9 are provided for a practical separation of the individual sections 10A-10L.
20 The tear lines are provided in the first portion 5 of the first 3 and/or the second 4 sheet material, such that after the applications of a tension force, a rupture of the material only occurs at the tear lines 8 and 9, leaving the sealed pouches in tact.
25 In figure 3 a schematic lay out plan for a perforation dye is presented. This lay out coincides with the pattern of tear lines 8 and 9 as presented in figure 2.
In figure 4 an endless band of heat storage material 7 is presented.
30 In figure 5 a cross sectional side view of an plate material such as an aluminium plate 11 is depicted.
The plate 11 is provided with a first pouch layer 14 on a first side A of the plate and a second pouch layer 15 on a 7 second side B of the plate 11. The first pouch layer 14 comprises the pouches 1A and IB, formed by the first sheet material 3A and the second sheet material 4A. The second pouch layer 15 comprises the pouches 1C and ID, formed by 5 the first sheet material 3B and the second sheet material 4B.
The pouches are glued on the flat side of the substantially flat layers 4A and 4B.
During manufacturing, the sheet material 3 can be 10 for instance be vacuum formed, embossed, or blown.
The invention is to be understood not to be limited to the exemplary embodiments shown in the figures and described in the specification. For instance the arrays of pouches can be in any width-length combination, even such 15 that every single pouch is surrounded by tear lines.
These and other modifications are considered to be variations that are part of the framework, the spirit and the scope of the invention outlined in the claims.
