Definitions

  • the present invention is framed in the field of construction elements used in building.
  • the object of the invention consists of an alveolar type slab that presents a series of elements based on phase change materials that facilitate thermal control.
  • the slabs that are flat and horizontal structures that fulfill the following functions are known: structural, habitability and as a chain condition.
  • the radiant floor can be installed on site or by pre-made modules.
  • Zhang et al Experimentally and numerically they studied a system of electrical heating of radiant floor with PCM in plates of stabilized form. They also developed a model to simulate soil behavior with the PCM of plates in a stabilized way to absorb heat from solar radiation during the day and its release at night in the heating station. The model was validated with the experimental results obtained in a test cell showing a good level of concordance. This model was used in a parametric study to conclude the following:
  • the appropriate melting temperature for the PCM is approximately equal to the average indoor air temperature for sunny winter days.
  • the latent heat of fusion and the thermal conductivity of the PCM must be greater than 120 kJ and 0.5 W / m-K.
  • the thickness of the PCM plate in a stabilized manner must not be more than 20 mm, and (iv) the thickness of the air layer between the PCM plates and the ground must be the smallest possible.
  • E Useful E Max Storable ⁇ ⁇ F c ⁇ FU Strictly speaking, all materials have the previous capacity, which is all the greater the greater their heat capacity (product of the density of the material due to its specific heat, p Cp). However, this capacity is much greater in materials capable of changing phase (Phase Change Material or PCM), since the latent heat associated with the change of state ( ⁇ ) is of an order of magnitude well above the sensitive heat that is associated to temperature changes.
  • Phase Change Material or PCM Phase Change Material
  • One of the main differences between the proposed constructive solutions and the traditional constructive solutions is that they include in their composition special materials capable of storing energy, and subsequently transferring it to the adjacent space.
  • the storage modules have so far been independent elements of the building (deposits with PCM).
  • these elements will be integrated into the structure of the building, using the slabs thereof.
  • the slab would be used as a cession and heat absorption system and as a storage system.
  • the slab and / or the slab object of the invention described herein allow latent heat storage by the use of phase change materials, compared to the conventional tendency to base the inertia of the enclosures on sensible heat exchanges. For this, an integration of the energy storage systems in the building's own structure has been carried out, in the face of the attempts that have been made where you go to warehouses or other external devices.
  • the working fluid is proposed is a controlled airflow of air for loading and unloading the phase change material that is found in the gaps of an alveolar slab, actually in other embodiments.
  • a different working fluid can be admitted, presenting in any case performance beyond the systems that have been obtained to date, since they allow a much greater storage capacity per unit of surface area.
  • the proposed system uses night ventilation as natural cooling techniques for energy loading
  • Figure 1. Shows a perspective view of the object of the invention.
  • Figure 2. Shows a perspective of the PCM containers mounted on the support structure.
  • Figure 3. Shows two sections corresponding to two possible fixing means for anchoring the PCM containers to the structure of support.
  • An alveolar slab (1) object of the invention is incorporated with a phase change material (PCM) in the free space of its alveoli.
  • the PCM is comprised in structures corresponding to a surface of revolution, such as in a preferred embodiment shown in Figure 1, containers (2) that are defined by a hollow revolution volume, in a preferred embodiment by metal cylinders - preferably aluminum or other metal with a high thermal transfer coefficient - duly sealed and / or closed by a flexible cover that closes it in its upper part which allows volume changes as a result of changes in the state of the material of change of phase. arranged on a support structure (3) in a cross configuration as shown in said figure 2.
  • the hollow containers (2) are preferably manufactured from aluminum tubes which, once cut, are filled with the phase change material and fixed to a matrix consisting of a metal sheet that acts as a support structure (3).
  • the fixing means is a welded joint, while an embodiment alternatively a threaded joint can be used; both possibilities are shown in figure 3.
  • Said containers have a flexible cap or lid, preferably made of a polymeric material, which is responsible for closing and / or sealing the container (2) preferably on its upper face, allowing some change of volume inside.
  • one or more gates can be arranged in such a way that they allow or condition the passage of air into the slab (1) and by contact the flow of working fluid with the containers (2) and therefore with the phase change material (PCM).
  • PCM phase change material
  • the object of the invention can incorporate an evaporative system adapted to facilitate evaporation, such as any evaporative system or material and / or a forced convection system such as a series of fans, convectors or the like.
