Definitions
- the present invention relates to a modular solar air collector for heating and ventilating spaces, of the type of collectors of which they have a transparent outer panel, and a heat-absorbing panel, which is mounted on the wall of the facade of a building , and comprising an air passage between the outer panel and the wall, an inlet opening in the lower part to allow the flow of cold air in the passage, and an outlet opening in the upper part for the output of the heated air when passing through the air passage.
- the purpose of the present invention is to provide a construction that simplifies the manufacture of solar collector panels of the current technique and increases efficiency.
- the FR2500036 patent describes a simple solar collector panel comprising a transparent outer panel, a thermo-absorbent rear panel that is thermally insulated on the rear wall, and a passage between the outer panel and the rear panel, which is provided with an opening of entrance at the bottom to allow the flow of cold air in the passage and an outlet opening at the top for the exit of the heated air through the rear panel.
- the rear wall of the rear panel facing away from the outer panel is thermally insulated to prevent heat flow from the heat absorbing rear panel and out of the solar collector panel.
- European patent EP1448937 describes a collector with a transparent or translucent outer panel (3), a rear panel (5), which is air permeable and open to the environment surrounding the solar collector panel (1) over a greater part of the area covered by the outer panel (3), heat-absorbing means (4) extending between said outer panel (3) and said rear panel (5) separated from them, the air-absorbing heat-absorbing means (4) being an opening of air inlet to the surrounding environment, and an air outlet opening (6) that extends outside the solar collector panel (1) and in the space to be ventilated and heated, characterized in that one or more photovoltaic cell panels (9) are arranged between the outer panel (3) and the heat-absorbing means (4), the air inlet opening is provided with the rear panel (5), and the air outlet opening (6) extends from the volume (8) enclosed by the outer panel (3) and the heat absorbing media (4) (claim 1).
- a solar collector panel 1 according to a first embodiment of the invention (shown in longitudinal section in Fig. 1) is shown, in which an aluminum frame 2 it holds a transparent outer panel 3 and a rear panel 5 made of a similar perforated aluminum plate that is left with a bare face directed towards the thermo absorbent means 4. All of this constitutes a housing that unnecessarily increases the weight and makes assembly difficult.
- EP1448937 see Fig. 5 there is a set of panels comprising a plurality of solar collector panels according to the first embodiment, mutually coupled and provided with a common outlet. This arrangement is difficult and complex, since it entails a large number of couplings and a consequent great loss of load and performance.
- EP1448937 allows the construction of a ventilation system (vid. Fig. 3) comprised of a plurality of panel assemblies, where the outlets are coupled to a common ventilation duct with a fan disposed therein. This entails the disadvantage that in certain cases, some of the collectors would work in the opposite direction to convection if the installation were done on a facade or sloping roof.
- the present invention is intended to provide an improved embodiment of a modular solar air collector that gives solution to the above drawbacks.
- the object of the present invention is a modular solar air collector of the type indicated at the beginning, of novel concept and design, which in essence is characterized, according to the independent claim 1 that follows, because it comprises modules with means of lateral coupling with similar modules, to constitute a manifold, and a widening of the air passage in the upper part which, when coupling multiple modules collaterally, determines a common plenum of air passage in a transverse direction, in the upper part of the manifold.
- the transparent outer panel and the heat absorbing panel are arranged adjacent or adjacent, the air passage being defined between the heat absorbing panel and the wall itself.
- the invention allows a great simplification of the construction of the solar collector.
- the transparent cover is used as a support element of the thermoab- sorbent (aluminum foil) and rear separator (plastic foil).
- the existence of the plenum according to the invention avoids additional external conduits and their loss of performance, and allows the connection between the collectors to be increased by increasing the air circulation section, and eliminating the loss of load and the performance of the systems of the prior art
- the plenum according to the invention collects the ascending hot air by convection from the collectors, allowing all collector modules to work in a single direction in case of installation on a sloping facade or roof.
- Fig. 1 is an exploded perspective view of a solar collector module according to the invention, in which its constituent elements are appreciated;
- Fig. 2 is a perspective view of a solar collector mounted from three modules of Fig. 1, according to the invention, coupled to a ventilation system, in the winter position of the assembly;
- Fig. 3 is an analogous view of Fig. 2, but in the summer position of the assembly.
- the module 1 of collector can be seen solar tor of the present invention, from which a solar collector 100 is mounted on a wall 2, especially for heating (in winter) and ventilation (particularly in summer) of spaces.
- the solar collector module 1 is formed as main constituent and functional elements by a transparent outer panel 3, preferably of cellular polycarbonate and a thermo-absorbent panel 4.
- the module 1 comprises an air passage 16, an inlet opening 5 in the lower part to allow the flow of cold air 200 (see lower arrows in Figs. 2 and 3) in the air passage 16, and an outlet opening 6 in the upper part for the output of the heated air 300 (see upper arrows in Figs. 2 and 3) when passing said air passage 16.
- a solar collector 100 is constituted by collaterally coupling several modules 1 through coupling means.
- said coupling means are constituted by supports 15 (especially visible in Fig. 1).
- the supports 15 are anchored to the wall 2 of the facade and can be for example extruded aluminum.
- Anchors 18 and a lower support 19 collaborate in mounting the panel 1 on the wall 2 in position.
- the transparent outer panel 3 and the heat absorbing panel 4 are arranged adjacent, the air passage 16 being defined between the heat absorbing panel 4 and the wall 2 or separating element 11 (plastic sheet).
- the module 1 has a widening 7 of the passage of air 16 which determines in the transparent outer panel 3, a portion of a concave transparent outer panel 10 and, in the thermo-absorbent panel 4, a concave thermo-absorbent panel portion 10.
- a concave widened part is determined which, by coupling multiple modules 1 laterally, determines a common plenum 8 of air passage in a transverse direction, in the upper part of the manifold 100.
- the central module 1 has an upper grid 12 in the plenum 8, intended to be closed in the heating (winter) position, and open in summer position, in which the outlet opening 6 closes.
- the grid 12 can also act as an overpressure valve when, in winter, the internal pressure of the heated system is greater than a predetermined value.
- cold air 200 penetrates through the lower inlet opening 5.
- the radiation transmitted through the transparent outer panel 3 heats the heat absorbing panel 4, which in turn heats the rising air by convection and radiation, which accesses the plenum 8 , from which it exits through the outlet opening 6, closing the grill 12, towards the hot air ducts 13.
- the plenum 8 collects the ascending hot air by convection from the collectors, allowing all modules 1 of the collector 100 to work in one direction only. installation case on a facade or sloping roof.
- the collector 100 formed with the modules 1 of the invention fulfill the function of a ventilated facade (or "shunt") in summer.
- the module 1 is provided with a separation sheet 11 from the wall 2, whereby the air passage 16 is defined between the heat absorbing panel 4 and this separation sheet 11.
- the air passage 16 is defined between the heat absorbing panel 4 and this separation sheet 11.
- this sheet insulation consisting of a sheet of low thermal transmission coefficient (plastic). That is, the heated air is not in contact with the facade or the exterior.
- the heat absorbing sheet 4 is perforated, to regulate the heat exchange with the air.
- the heat absorbing panel 4 can be constituted from an aluminum foil, although it can also be made of other heat absorbing materials, metallic or not.
- the modules 1 may comprise a perimeter side closure 18 of elastomer, adaptable to different types of façade, so as to ensure the tightness of the manifold 100. Sufficiently describing the nature of the present invention, as well as how to implement it, is It states that everything that does not alter, change or modify its fundamental principle is subject to variations in detail. In this sense, the number, shape and arrangement or alignment mode of the modules 1 for forming the manifold 100 can be any other than those illustrated by way of example. Likewise, the concave form of the plenum can present other geometries that ensure its function.
