Definitions

  • the present invention is framed in the field of construction elements used in building.
  • the object of the invention consists of a facade that presents a series of elements based on materials with phase change that facilitate thermal control.
  • Ventilated or transventilated facades based on a constructive exterior enclosure system consisting of an inner sheet, an insulating layer, and a non-waterproof outer sheet are known. It is a usual solution in institutional and representative buildings.
  • a substructure On the facade of the building (inner sheet) a substructure is anchored to support the outer finishing sheet.
  • the substructure leaves an air chamber of a few centimeters between the inner sheet and the second skin.
  • the outer or finishing skin should have grooves in both the lower and upper part, to allow air renewal. At the singular points (ridge line, perimeter of windows), they must be dispose of gutters or other protection elements to hinder the entry of water into the internal chamber, the existence of the outer sheet helps reduce the thermal losses of the building: in the summer months the outer skin is heated creating a convective effect that circulates the air inside the chamber. This "chimney effect" dislodges hot air and renews it with colder air. In the winter months the air in the chamber is heated, but not enough to create the same effect and the heat is better preserved. On the other hand Feldman et al. They tested a wall with real size PCM.
  • the enclosure or facade objects of the invention described herein they allow latent heat storage through the use of phase change materials, compared to the conventional tendency to base the inertia of the enclosures on sensible heat exchanges; in addition to dispensing with adhesives or other fixing means that are not suitable for fixing phase change materials (PCM).
  • PCM phase change materials
  • the facade uses a controlled air flow to load and unload the phase change material that is in the chamber, in fact in other alternative embodiments a working fluid can be admitted different, presenting in any of the cases benefits beyond the systems that have been obtained to date, since they allow a much greater storage capacity per unit of facade surface.
  • the proposed system uses night ventilation as a natural technique for the freezing phase of the PCM.
  • the insulation is placed on the second skin.

  • Figure 3c Shows the operation of the object in an exterior-interior configuration.
  • Figure 3d. Shows the operation of the object in an interior-exterior configuration.
  • the enclosure (1) ventilated with phase change material (2) object of the invention bases its operation on heat transfer between the phase change material and the means with which said phase change material (2) is in contact; which usually sets the limit of the amount of energy that can be stored and / or transferred.
  • a strategy of extended surfaces or containers (4) is proposed that this preferred embodiment is defined by slats, type fins of phase change material or a mixture thereof or essentially flat containers (4) in the form of hollow fins inside which the phase change material is located, to increase the contact area between the air and the phase change material (2) -PCM for its acronym in English.
  • the enclosure (1) defined by a façade that can incorporate a forced convection system (3) located in such a way that it can favor or promote the movement of air in contact with the containers (4) is presented - one or several fans of tangential or radial type - by mechanical drive to increase the film coefficient, as seen in figure 1.
  • the object of the invention has a hollow chamber, an air chamber, preferably defined next to the inner face of an outer sheet of the enclosure (1), which can be configured such that it is possible to carry out tests in convection mode free and forced for the following provisions:
  • a ventilated enclosure (1) defined by a conventional ventilated facade.
  • it can be a Trombe wall.
  • a ventilated enclosure (1) with characteristics based on the physical phenomenon of phase change. So that the enclosure (1) can alternate between the first and second embodiment, an opaque insulating element is superimposed on the glazing. This opaque insulating element is removable in such a way that when said opaque element is mounted the object of the invention corresponds to a ventilated enclosure (1) and when disassembled it becomes a Trombe wall.
  • the containers (4) in this case the lamas or hollow section fins, continuous but can be diminishing section lamas or any other type of container form (4), comprising the phase change material (2) is they can be fixed to a frame (5) which will be incorporated into the inner wall, in such a way that the slats can be removed, which allows testing with and without a slat, likewise the object of the invention can comprise at least one gate (6 ) intended to control the passage of air into the enclosure (1), both frame elements (6) and gate (6) are detailed in Figure 2.
  • the carpentry of the ventilated enclosure (1) has been designed with at least one gate (6), designed to control the passage of air into the enclosure (1), which allows the following flow patterns, as see in figures 3a, 3b, 3c and 3d respectively:
  • the first three are preferably used.
  • Forced convection is achieved thanks to the incorporation of the aforementioned forced convection system (3) and / or which may have in a preferred embodiment a defined number between one and three tangential fans capable of displacing an estimated flow rate of 2000 cubic meters per hour.

Abstract

L'invention concerne une paroi ou une façade ventilée qui comprend un mur, et qui est caractérisée en ce qu'elle contient une série de contenants à l'intérieur desquels est présent un matériau à changement de phase destiné à stocker du froid et/ou de la chaleur pendant certaines heures de la journée pour redistribuer le froid et/ou la chaleur pendant d'autres heures de la journée lorsque cela s'avère nécessaire.
