  • Flexible heat storage tube containers are provided by this invention which provide some or all of the desired properties in the field of flexible tube containers adapted for heat or cold storage.
  • Essentially parallel series of such heat storage tube containers are also provided, as from two sheets of selected flexible film, which are referred to as heat storage tubesheets.

  • the walls of the tube container and tubesheets are flexible so that when the respective tube containers are filled with PCM and suspended in a horizontal orientation from top thereof, the tubes are sufficiently flexible so that the cross section of the tube container is not circular or essentially circular but rather is asymmetrical in shape, such as elliptical and can flex and adjust in shape in response to the expansion and contraction of the PCM to retain a high degree of intimate contact.
  • a typical tube container when filled in a vertical position will have a circular cross sectional configuration.
  • the walls of the tube containers have a low MVTR (moisture vapor transmission rate), such as below about 0.01 gram.

  • the PCM can comprise Glauber's salt.
  • the PCM can also include a suspending agent, nucleating agent, agents providing for altering the PCM, such as its phase change temperature, and the like.

  • layer 31 is an aluminum foil; and
  • layer 32 is made of nylon 6. The layers are adhered one to the other with adhesive.
  • the completed and filled tubesheet 10 is suspended and held in a vertical position with the tube containers horizontally disposed, by suspending element 21. It is noted that the tube containers have an elliptical cross section.
  • the tubesheet is made as by placing two films of flexible materials which provide the proper characteristics in contact. If the films are laminates having different materials on the two sides of the film, the two films are placed one on top of the other so that the sides having the same sealable material will be facing each other. If the films are to be welded together as by heat sealing, the sides having the materials which are readily heat welded and provide other desired properties are placed in contact with each other.
  • the size of the films is selected to provide desirable dimensions in the final heat storage tube containers depending upon the capacity desired in the tube container, the cycle time desired, the size and the location of the enclosure or other storage structure used for positioning the tubesheets to function in heat or cold storage, and other factors.
  • the dimensions of the starting films used in constructing the tubesheets can vary. It has been found suitable in many applications such as home use, for example, that the dimensions of the original films are about 24 in. by about 36 in.
  • the tube containers can desirably be about 8 in. by about 24 in.
  • the tubes can have a smaller or larger width. For example, it has been found that 10 to 12 in. width tube containers can be effectively used. Tubes with wider width carry a heavier load per in. of seal, assuming the final tubesheets in operation are suspended from the top thereof so that the tube containers are in a horizontal position. Therefore, in the use of increasing width container tubes, one must be certain that the seal strength of the container tubes is sufficiently high to withstand rupture.
  • the width of the seals made to form the tube container can vary in width so long as they are sufficiently wide to provide the strength to hold the PCM composition placed into the final tube container.
  • a heat seal width of about 3/8 in. is sufficient.
  • the width can suitably be varied such as within the range of from about 1/4 in. to about 1 in. so long as sufficient strength is provided to contain the stored PCM composition over a long term period. Unnecessarily wide seals should be avoided for economic reasons and for efficiency of operation of the tubesheets.
  • the seals can be multiple such as double with an unsealed spacing between the seals, such as about 1/4 to about 1/2 inch, or more if desired, to produce desired configurations or characteristics.

  • the films used in making the laminated film can vary in thickness. It has been found for many purposes that polyamide films and aluminum foils of about 0.5 mil function well. The films can be increased in thickness as required up to about 2 mil or more so long as the final laminated film provides the required flexibility and other required properties.
  • the nylon film layer can be an oriented film to provide greater strength.
  • the aluminum foil desirably is the core laminated layer.
  • the polypropylene film suitably has a thickness of about 3 mil, desirably in the range of about 1 to about 5 mil.
  • the thickness can be varied depending upon the width of the final tube containers, the weight which the tube containers must hold, seal strength required and sealing conditions, temperature used and other factors.
  • the final laminated films used to make the tube containers and tube sheets should not exceed what provides satisfactory properties.
  • Suitable adhesives known to the art are used in the lamination, e.g., urethane adhesives.
  • Other films can be substituted and yet retain the required characteristics of the final, filled tube containers and tubesheets and such substitution will be suggested to those skilled in the art to whom this disclosure is directed with the benefit of this disclosure.
  • the PCM used can be widely varied. It has been found desirable to use sodium sulfate and sufficient water to form the sodium sulfate decahydrate, also called Glauber's salt.
  • PCM components can be used so long as the phase change occurs at an appropriate temperature.
  • Other materials which can be used are calcium chloride, sodium thiosulfate, sodium chloride, ammonium chloride, potassium chloride, and others which are known to those skilled in the art.
  • Certain materials can be added to the PCM composition.
  • an amount of a nucleating agent can be used.
  • a suitable nucleating agent is borax.
  • a presently desirably amount of borax as the nucleating agent is about 2 to 5 percent of the total PCM composition. The amount can be varied widely so l ong as desired nucl eation is provided.
  • nucleating agents can be used.
  • Suspending agents are also desirably used. It is presently preferred to use certain starch derivative suspending agents such as sold under the designation J-400 and J-500
  • the starch derivative suspending agents can, for example, be polyacrylonitrile-starch graft copolymers formed as by graft copolymerization of acrylonitr ile with a suitable starch.
  • the graft polyacrylonitrile starch copolymers can be saponified with suitable aqueous bases. It is understood that J-
  • the starch graft copolymer suspending agents can be cross linked to a degree so long as the crosslinking does not interfere with the suspending action.
  • the graft starch copolymers desirably used are called in the art superabsorbent polymers. It is presently believed that presently preferred graft starch copolymer suspending agents, such as polyacrylonitrile-starch graft copolymer superabsorbent suspending agent become more fluid as the PCM changes to the liquid phase and in turn becomes more viscous during the conversion of the PCM to the solid phase.
  • the amount or suspending agent will vary depending upon the PCM and other factors. It has been found suitable to employ an effective amount, such as in the range of about 0.5 to 5 percent based on the weight of the PCM composition. About 1 to 2 percent of J-400 and J-500 has been found satisfactory in Glauber's salt PCM compositions.

Abstract

Nouveaux récipients (20) de stockage de chaleur à tubes et plaques tubulaires adaptés pour stocker et libérer de la chaleur, et pour refroidir au moyen de matière de changement de phase (''PCM'') (22) logée à l'intérieur de tubes de stockage (20). On peut employer des matières chimiques ayant une fusion thermique latente élevée (capacité en kWh élevée) telles que le sel de Glauber (décahydrate de sulfate de sodium) pour le stockage chaleur telle que celle produite par des unités solaires. Le PCM est logé dans des récipients (20) de stockage à tubes à structure de paroi souple réalisée à partir de deux couches minces de matière, par exemple des feuilles (11, 12) polymères, par soudage thermique (13, 14). On peut produire des systèmes de stockage de chaleur ou de froid en formant un réseau réalisé à partir des tubes (20) du récipient ou des plaques tubulaires, à l'intérieur d'une enveloppe pourvue d'une entrée et d'une sortie destinées à de l'air ou à un autre milieu à chauffer ou à réfrigérer. Des procédés de chauffage et de réfrigération d'air ou d'autres fluides au moyen des systèmes sont également décrits.
