  • the prisms are adjusted so that the heat radiation of the sunlight is at least partially reflected in the high sun in summer, while the heat radiation is transmitted in low sun in winter. This avoids overheating in the summer and supplies solar energy to the latent storage in winter.
  • a fluid-carrying pipe is provided, which is connected to a heater, so that the latent storage can be supplied in the winter with additional heat energy, if the solar energy should not be sufficient for heating the facade element to room temperature.
  • a part of the storage medium PCM is directly adjacent to the tubes, so that the heat entrained by the fluid can be released via the tubes to the storage medium located in the immediate vicinity of the tubes and only then migrates to more remote areas of the latent accumulator.
  • PCM has a poor thermal conductivity with the result that a temperature gradient arises in the latent reservoir and that a higher temperature prevails in the area of the tube than in more remote areas, so that the heat transfer from the tube to the storage medium is difficult.
  • DE 198 51 710 C2 proposes to arrange metal stiffeners (or metal fibers) oriented perpendicularly to the surface in the fiber base material, the metal strips constituting only about 2% by volume of the fiber base material.
  • metal stiffeners or metal fibers
  • the thermal conductivity of the latent storage is improved to the surface of the composite plate, but not the overall thermal conductivity, because these metal strips are substantially perpendicular to the surface, ie parallel to each other, aligned and thus have no contact with each other.
  • the object of the present invention is to provide a façade or roof element of the type mentioned in the introduction in which rapid heat transfer takes place between the fluid-carrying line and the latent memory.
  • a trained according to this technical teaching façade or roof element has the advantage that the thermally conductive lightweight board, which is in thermal contact with the fluid-carrying line, the heat stored in the latent storage transported very quickly to the fluid-carrying line and vice versa, so that the fluid-carrying Conduit provided heat can be distributed very quickly in the latent memory.
  • Another advantage is that the storage medium held in open pores of the lightweight construction board has a large contact surface with the lightweight building board, so that heat can be transferred in a very short time via this large contact area.
  • a latent accumulator is created by the thermally conductive, open-porous lightweight board with the storage medium stored therein, which has, among other things due to the good conductivity of the lightweight panel a very uniform temperature distribution and in which the heat stored in the latent storage on the Lightweight panel gives very quickly to the fluid-carrying line. It is understood that in the opposite direction, the outgoing from the fluid-carrying line heat is distributed very quickly and evenly through the lightweight board in the latent memory. As a result, this leads to the advantage that the façade or roof element according to the invention can deliver stored heat quickly and with little loss to the fluid-carrying line, for example in order to operate a heat pump with it.
  • Another advantage is that the occurring solar heat is distributed very quickly throughout the latent storage by the thermally conductive, open-pore lightweight board, so that local overheating be avoided.

  • the outer wall comprises two glass panes arranged in parallel, between which a vacuum is formed. Due to this vacuum, the façade or roof element achieves a very high insulating effect, so that the heat stored in the latent storage is only lost to the outside wall again to a very small percentage.
  • the outer wall is formed as two or three panes having insulating glazing.
  • insulating glazings are known in the prior art and also have good insulation values, so that the heat present in the latent storage is lost again only to a small percentage.
  • the line leading through the latent accumulator is used to supply heat to the latent accumulator in winter, so that the space behind it is sufficiently heated.
  • the solar energy is used only to support the winter heating.
  • the invention proposes to remove excess solar energy via the fluid-carrying line, and to supply it to a heat pump, especially in the summer and in the transitional period, a transparent thermal insulation and a latent storage. About this heat pump can then be heated, for example, hot water or a heater can be supported.
  • a latent memory thus has an ideal temperature for the persons in the room, which will have the consequence that the room temperature is also at least approximately located in this area. In summer, such a temperature causes the inhabitants to perceive the façade element as an area from which a pleasant coolness emanates. In the winter goes by the facade element a perceived as pleasant low-temperature radiant heat. As a result, a very pleasant room climate is created all year round by the selected phase change temperature.

Between the first glass pane 16 and the second glass pane 18, a vacuum 20 is formed in order to achieve a good thermal insulation of the outer wall 12. The spacers 20 thereby cause the glass sheets 16, 18 do not bend and break due to the forces caused by the vacuum.

In this case, the incoming solar energy is rapidly distributed throughout the latent memory 14 by the lightweight building board 24 and its high thermal conductivity. Due to the large contact area between the lightweight board 24 and the storage medium 28, the heat of the sun is quickly released to the PCM. Because the PCM has a phase change temperature between 21 0 C and 22 0 C, the latent memory 14 usually also has a temperature between 21 0C and 22 0 C. Through the conduit 26 flows a fluid, such as water or glycol at a lower temperature, which is why the fluid is heated on its way through the facade or roof element. Again, there is a rapid heat transfer from the storage medium PCM to the fluid instead, because the lightweight board 24 has a good thermal conductivity and thus the heat can quickly transport from the PCM to the fluid.
