Definitions

  • the present invention relates to a flat solar collector intended to be mounted on a structure, particularly a roof or a façade of a building.
  • a solar collector is a module designed to convert the energy originating from solar radiation into thermal energy collected in a heat-transfer fluid.
  • a flat solar collector comprises two walls facing one another and which between them delimit a housing accommodating energy conversion elements, generally in the form of an absorber panel thermally connected to one or more pipes through which the heat-transfer fluid flows. At least one of the two facing walls is transparent and intended to face in the direction of the solar radiation incident upon the collector so as to permit good transmission of solar radiation towards the energy conversion elements.
  • the collector In order to increase the energy conversion efficiency of such a solar collector, it is known practice to create a vacuum in the housing accommodating the energy conversion elements, which makes it possible to limit thermal losses through convection and molecular conduction. In such instances, in order to counter the compressive force applied to the walls of the collector as a result of the external atmospheric pressure, the collector is fitted with spacers that make it possible to maintain a constant distance between the facing walls.
  • the energy conversion elements are also advantageously kept some distance away from the walls that delimit their accommodating housing, again with a view to limiting thermal losses through contact at these walls.
  • WO-A-87/06328 describes an evacuated solar collector structure in which the spacers are in the form of rods, which rest between the two facing walls of the collector. These rods are distributed in the collector some distance away from the pipes in which the heat-transfer fluid flows and pass through the absorber panel. When the rods that form the spacers are made of metal, thermal losses are likely to occur at these rods. In addition, because the absorber panel is pierced with holes through which these rods can pass, the active area of the panel available for absorbing the energy originating from the solar radiation is reduced, and this limits the energy conversion efficiency of the collector.
  • the invention more specifically sets out to remedy by proposing a solar collector having a structure that is optimized both in terms of thermal distribution in the collector and in terms of mechanical strength of the collector, making it possible to improve the energy conversion efficiency of the collector, this solar collector also having a minimized size and a simple method of manufacture.
  • one subject of the invention is a solar collector comprising:
  • a transparent element is an element that is transparent at least in the wavelength ranges of the solar radiation that are of use for the convertion by the absorption means of the energy originating from the solar radiation into thermal energy.
  • a spacer is said to be positioned between the first wall and the absorption means at or in the region of a pipe when it is positioned between the first wall and the pipe, with or without the interposition of other absorbing elements between the spacer and the pipe. The spacer is then in thermal contact with a relatively cooler part of the absorption means, because the heat-transfer fluid flows through the pipe.
  • each spacer is positioned in the region of a heat-transfer fluid circulation pipe, that is to say at a cold point of the absorption means, the thermal losses across the spacer are limited.
  • the transparency of the first wall and of each spacer positioned between the first wall and the absorption means guarantees good transmission of solar radiation towards the absorption means of the collector. The collection by the absorption means of energy originating from solar radiation and the energy conversion efficiency of the collector are thus optimized.
  • Another subject of the invention is a cladding assembly for a structure, particularly a roof or a façade of a building, comprising at least one solar collector as described hereinabove.
  • FIG. 1 is a cross section of a solar collector according to a first embodiment of the invention
  • FIG. 2 is a section similar to FIG. 1 for a solar collector according to a second embodiment of the invention
  • FIG. 3 is a section similar to FIG. 1 for a solar collector according to a third embodiment of the invention.
  • FIG. 4 is a schematic plan view from above of two solar collectors according to the invention, mounted on a structure, for example a roof or a façade of a building; and
  • FIG. 5 is a side view of a roof structure on which solar collectors according to a fourth embodiment of the invention are mounted.
  • FIGS. 1 to 5 have not been drawn strictly to scale.
  • the solar collector 1 of the first embodiment comprises a transparent upper wall 2 intended to face in the direction of the solar radiation incident upon the collector, and a lower wall 4 which is likewise transparent.
  • the walls 2 and 4 are formed of two identical sheets of toughened glass, rectangular in shape and of the order of 4 to 6 millimeters thick.
  • the walls 2 and 4 are joined together by means of a metal frame 5 such that together and with the frame 5 they delimit a housing 3 to accommodate the absorption means of the collector 1 .
  • the midplanes ⁇ and ⁇ ′ of the walls 2 and 4 are substantially mutually parallel.
  • a thickness direction of the collector 1 which is substantially perpendicular to the midplanes ⁇ and ⁇ ′, is denoted Z.
  • each of the walls 2 and 4 is fixed to the frame 5 by means of a fluidtight seal 10 , particularly a gas tight seal.
  • the seal 10 between the metal frame 5 and each glass wall 2 or 4 is obtained by soldering, using a soldering alloy, between the frame and a metallic frit deposited on the glass wall.
  • This metallic frit comprising a glass frit and metallic particles, is advantageously applied by screen printing to the periphery of that face of the glass wall 2 or 4 that is intended to come into contact with the frame 5 , and is then baked during the heat toughening of the glass wall 2 or 4 .
  • the seal 10 obtained between the glass and the metal has good mechanical strength and sealing properties over the long term.
  • the seal 10 allows the housing 3 in which the absorption means of the collector are located to be placed under and kept under vacuum.
  • These absorption means comprise a metallic panel 6 , also known as the absorber panel, and a pipe 7 through which a heat-transfer fluid flows.
  • the heat-transfer fluid is, for example, water, possibly mixed with an antifreezing agent.
  • the absorber panel 6 is positioned between the upper wall 2 and the pipe 7 through which the heat-transfer fluid flows, so that it is able to store heat originating from the solar radiation passing through the wall 2 , this heat then being transferred from the absorber panel 6 to the fluid flowing through the pipe 7 .
  • the pipe 7 is in thermal contact with the lower face 6 A of the absorber panel 6 facing toward the lower wall 4 .
  • the pipe 7 is positioned against the lower face 6 A of the absorber panel 6 in the form of a serpentine coil, so as to maximize the area for thermal contact between the pipe and the absorber panel.
  • the absorption means 6 and 7 are preferably held at a median plane P of the collector, at some distance from the walls 2 and 4 , so as to limit thermal losses through contact at these walls.
  • the absorber panel 6 particularly made of copper or of aluminum, has a thickness in the Z direction of the order of 0.1 to 1 millimeter.
  • the pipe 7 particularly made of copper, is of circular cross section with a diameter of the order of 8 mm.
  • the pipe 7 opens to the outside of the collector 1 at two inlet and outlet connectors 11 for the heat-transfer fluid, these being depicted schematically in FIG. 4 .
  • the two connectors 11 are provided on one and the same edge face of the collector 1 , that is say are installed on one and the same side 51 of the rectangular shaped frame 5 , each being positioned near one end 51 A or 51 B of the side 51 .
  • the side 51 of the frame 5 that comprises the connectors 11 is preferably positioned the highest up by comparison with the other sides of the frame.
  • a solar collector system is thus formed in which the heat-transfer fluid can flow, through a plurality of collectors in succession.
  • a plurality of spacers 8 and 9 in the form of pads, is provided in the collector 1 to maintain a constant distance between the upper wall 2 and the lower wall 4 when the collector is placed under vacuum.
  • the collector 1 thus comprises a first series of spacers 8 , called upper spacers, which are positioned between the upper wall 2 and the absorption means, and a second series of spacers 9 , called lower spacers, which are positioned between the lower wall 4 and the absorption means.
  • the spacers 8 , 9 are distributed in the collector 1 in such a way as to form pairs of spacers.
  • Each pair of spacers comprises an upper spacer 8 and a lower spacer 9 which are substantially aligned in the Z direction and positioned on each side of the absorption means, each time in the region of the pipe 7 .
  • each upper spacer 8 is positioned between the upper wall 2 and a portion 61 of the absorber panel 6 which is in thermal contact with the pipe 7
  • each lower spacer 9 is positioned between the lower wall 4 and the pipe 7 .
  • the spatial arrangement of the spacers 8 , 9 each time in the region of a portion of the pipe 7 , allows thermal losses through the spacers from the absorption means 6 and 7 to be limited.
  • the pipe 7 and the portions 61 of the absorber panel 6 which are in thermal contact with the pipe 7 are cold zones in the thermal distribution of the absorption means, thus limiting the risk of thermal leaks through the spacers.
  • each spacer 8 or 9 is a feature in relief that protrudes with respect to the corresponding wall 2 or 4 and is formed by rolling the sheet of glass of which the wall 2 or 4 is made.
  • the series of upper spacers 8 is a surface texture of the upper wall 2 , obtained by rolling the flat surface of the sheet of glass of which the wall 2 is made, by heating the sheet of glass to a temperature at which it is possible to deform its surface using a solid object such as a metal roller which on its surface has the inverse of the texture that is to be formed.
  • the series of lower spacers 9 is a surface texture of the lower wall 4 , obtained by rolling the flat surface of the sheet of glass of which the wall 4 is made.
  • the rolled spacers 8 and 9 are toughened during the heat toughening of the walls 2 and 4 . Spacers 8 and 9 are thus obtained which are incorporated into the glass wall 2 or 4 and which have good transparency and mechanical strength properties.
  • the solar collector 101 differs from the solar collector 1 of the first embodiment through the structure of its spacers 108 and 109 .
  • the solar collector 101 comprises a transparent upper wall 102 and a lower wall 104 which is likewise transparent, these two being formed by two identical sheets of heat-toughened glass.
  • absorption means which are similar to those of the first embodiment, comprise an absorber panel 106 and a pipe 107 in which a heat-transfer fluid flows.
  • the pipe 107 is in thermal contact with the absorber panel 106 on the side of the lower face 106 A thereof.
  • the collector 101 comprises a plurality of upper spacers 108 and a plurality of lower spacers 109 which are intended to maintain a constant distance between the upper wall 102 and the lower wall 104 when the collector 101 is placed under vacuum.
  • these spacers 108 and 109 are aligned in pairs in the Z direction of thickness of the collector 101 , so that each upper spacer 108 is positioned between the upper wall 102 and a portion 161 of the absorber panel 106 which is in thermal contact with the pipe 107 , while each lower spacer 109 is positioned between the lower wall 104 and the pipe 107 .
  • the spacers 108 and 109 are not in the form of features in relief obtained by rolling but are in the form of glass beads added on to the walls 102 and 104 , for example by bonding.
  • the glass beads are strengthened by chemical toughening.
  • This chemical toughening treatment seeks, by ion exchange, to replace the alkaline ions initially present in the glass and close to the surface with other, larger, alkaline ions with a view to inducing high compressive stresses at the surface. Chemical toughening thus makes it possible to significantly increase the mechanical strength of the beads.
  • the glass of which the beads is made needs, prior to toughening, to contain an alkaline oxide.
  • the initial oxide may be Na 2 O, it then being possible for the chemical toughening to be carried out by treatment with KNO 3 , so as to replace, at least partially, the Na + ions with K + ions; the initial oxide may also be Li 2 O, it then being possible for the chemical toughening to be carried out by treatment with NaNO 3 or KNO 3 so as to replace, at least partially, the Li + ions with Na + or K + ions.
  • the chemical toughening leads to an ion, notably K + or Na + , concentration gradient perpendicular to the treated surfaces and which decreases away from these surfaces.
  • the ion exchange is performed by dipping the glass beads in a bath of potassium salt raised to temperatures comprised between 400 and 500° C.
  • the ion exchange parameters notably the temperature and duration, are chosen to encourage a high surface stress. Ion exchange may also be assisted by an electric field.
  • the solar collector 201 differs from the solar collector 1 of the first embodiment in that its lower wall 204 is made of metal. More specifically, the solar collector 201 comprises a transparent upper wall 202 , formed of a sheet of heat-toughened glass, and a metal tray 215 .
  • the metal tray 215 comprises a bottom 204 which forms a lower wall of the collector 201 , and a lateral edging 205 which extends substantially perpendicular to the bottom 204 .
  • the upper wall 202 is connected to the free edge of the edging 205 by means of a fluidtight, particularly a gas tight, seal 210 .
  • the seal 210 between the metal edging 205 and the glass upper wall 202 is preferably obtained by soldering together the free edge of the edging 205 and a metallic frit applied to the upper wall 202 .
  • the walls 202 and 204 between them and with the edging 205 delimit a fluidtight housing 203 in which are housed the absorption means 206 and 207 of the collector 201 , which comprise an absorber panel 206 and a pipe 207 for the flow of a heat-transfer fluid which is in thermal contact with the absorber panel 206 on the lower face 206 A side thereof.
  • the collector 201 comprises a plurality of upper spacers 208 and a plurality of lower spacers 209 , which are aligned in pairs in the Z direction of thickness of the collector 201 and designed to maintain a constant distance between the upper wall 202 and the lower wall 204 when the collector 201 is placed under vacuum.
  • Each upper spacer 208 is positioned between the upper wall 202 and a portion 261 of the absorber panel 206 which is in thermal contact with the pipe 207
  • each lower spacer 209 is positioned between the lower wall 204 and the pipe 207 .
  • the upper spacers 208 are features in relief which project with respect to the upper wall 202 , formed by rolling the sheet of glass of which the wall 202 is made, and which are advantageously toughened when the wall 202 is being heat toughened.
  • the lower spacers 209 for their part are features in relief which project with respect to the lower wall 204 , formed by embossing the metal wall 204 .
  • an insulating sheet 214 is added between the pipe 207 and the metal lower spacers 209 in order to reduce thermal losses.
  • This sheet is preferably non-porous in order to make it easier to place the collector under vacuum and may, for example, be made of glass or of ceramics, with a thickness of the order of 1 to 4 millimeters.
  • the lower spacers 209 are preferably aligned with the pipe 207 in the Z direction, although this is not compulsory.
  • each upper spacer 8 , 108 , 208 or lower spacer 9 , 109 , 209 has a thickness e 8 , e 108 , e 208 or e 9 , e 109 , e 209 less than 4 millimeters, preferably less than 2 millimeters. More specifically, when the spacers are glass beads that have undergone a chemical toughening treatment as in the second embodiment, these beads preferably have a thickness less than 2 millimeters.
  • these spacers are made of glass, of one piece with a glass wall of the collector and heat toughened during the heat toughening of the wall, as is the case with the rolled spacers 8 , 9 and 208 of the first and third embodiments, these spacers preferably have a thickness less than 1 millimeter.
  • each spacer 8 , 108 , 208 , 9 , 109 , 209 advantageously has a shape that is rounded in the direction of the absorption means, particularly a spherical or hemispherical shape, so as to minimize the area of contact between the spacer and the absorption means and thus limit thermal losses through the spacer. Attempts are also made at minimizing the spacers density on each of the upper and lower walls, notably by maximizing the value of the pitch p between the spacers, so as to limit the thermal losses through the spacers.
  • the value of the pitch p between the spacers on each wall is adjusted in order to reach a compromise between, on the one hand, minimizing the thermal losses through the spacers and, on the other hand, the distribution of stress through the wall.
  • Increasing the pitch p between the spacers leads to an increase in the concentration of the mechanical stresses generated in the wall, and therefore increases the risk of this wall breaking when it is made of glass.
  • a good compromise is obtained for a value of the pitch p between the spacers between 20 and 100 millimeters.
  • a solar collector according to the invention provides good transmission of solar radiation towards the absorption means of the collector by virtue both of the transparency of the upper wall and of the transparency of the upper spacers.
  • the entire active surface area of the absorber panel is exposed to the solar radiation, making it possible to improve the collection of energy by the absorber panel.
  • the upper wall and/or the upper spacers are made of a transparent clear or extra-clear glass with a very low iron oxides content, such as the glass marketed by Saint-Gobain Glass in the “DIAMANT” range or, particularly when the upper spacers are features in relief obtained by rolling the upper wall of the collector, in the “ALBARINO” range manufactured by rolling.
  • a transparent clear or extra-clear glass with a very low iron oxides content such as the glass marketed by Saint-Gobain Glass in the “DIAMANT” range or, particularly when the upper spacers are features in relief obtained by rolling the upper wall of the collector, in the “ALBARINO” range manufactured by rolling.
  • a solar collector according to the invention also makes it possible to limit thermal losses by virtue, on the one hand, of the creation of the vacuum in the housing that accommodates the absorption means and, on the other hand, of the specific way in which the spacers are arranged in the collector. Positioning the spacers at the cold points of the absorption means, in the region of the pipe through which the heat-transfer fluid flows, effectively makes it possible to reduce the thermal losses through the spacers, as does the rounded shape of each spacer in the direction of the absorption means, which allows the area of contact between the spacer and the absorption means to be minimized.
  • a solar collector according to the invention can have an energy conversion efficiency that exceeds the efficiencies of the solar collectors of the prior art.
  • a solar collector according to the invention may also have a very compact structure by virtue, on the one hand, of the use of walls and spacers made of toughened glass or of metal which, even they have relatively small thicknesses, exhibit good mechanical strength and, on the other hand, of the possibility of effectively maintaining a vacuum in the housing that accommodates the absorption means through the fitting of a glass-metal seal as described earlier.
  • the thickness e 1 , e 101 , e 201 of the solar collector is less than 30 millimeters, preferably less than 25 millimeters. Thanks to its compactness, a solar collector according to the invention can easily and esthetically be incorporated into a roof or a façade of a building.
  • a solar collector according to the invention can improve the thermal insulation of the roof or the façade to which it is fitted.
  • a solar collector according to the invention when it comprises spacers formed collectively on one wall of the collector, eliminates the need to fit spacers individually in the collector. This is notably the case when the collector comprises rolled or embossed spacers as described earlier, or alternatively spacers formed by applying a glass frit to the wall by screen printing, in a single pass of the squeegee, then by baking this glass frit. Thanks to this collective manufacturing of the spacers, the method for manufacturing the solar collector is simpler and faster, which is advantageous for manufacture on an industrial scale.
  • a solar collector according to the invention advantageously forms part of a cladding assembly 20 , 320 intended to be mounted on a structure, such as a roof or a façade of a building, in which the cladding assembly 20 , 320 comprises other elements, notably other solar collectors and/or photovoltaic modules and/or conventional tiles or slates.
  • the various elements of the cladding assembly 20 , 320 are preferably arranged in relation to one another in a stepped arrangement with overlap, in the manner of tiles or slates, and joined together by fixing means which have not been depicted, for example hooks and rails with saw-tooth edges as described in US-A-2003/0213201.
  • the shape of solar collectors according to the invention can easily be adapted to facilitate a stepped arrangement of the collectors on a roof or façade of a building, with overlap in the manner of tiles or slates.
  • Each solar collector 301 according to this fourth embodiment has the same structure as any one of the collectors 1 , 101 , 201 described earlier, except that the upper wall 302 of the collector 301 is given a height h 302 , in a height direction Y of the collector 301 , that exceeds the height in the Y direction of the underlying parts of the collector, and is notably greater than the height h 304 of the lower wall 304 of the collector.
  • the walls 302 and 304 are arranged in such a way that two opposite free edges 321 and 323 of the upper wall 302 protrude a distance d beyond the corresponding free edges 341 and 343 of the lower wall 304 .
  • the collector 301 When the structure that accommodates the collector 301 is inclined with respect to the horizontal, as is the case with the structure 312 depicted in FIG. 5 , the collector 301 is intended to be mounted on the structure with its height direction Y substantially aligned with the direction of inclination of the structure with respect to the horizontal.
  • the upper wall 302 of the collector 301 when the collector 301 is in the configuration in which it is mounted on the inclined structure 312 , the upper wall 302 of the collector 301 is able partially to cover the upper wall 302 of an analogous second collector 301 mounted on the structure 312 juxtaposed below the first collector 301 in the direction of inclination of the structure.
  • This then yields a cladding assembly 320 comprising several collectors 301 with the desired stepped arrangement, in the manner of tiles, on the structure.
  • Such a stepped arrangement of the collectors 301 gives the cladding assembly 320 good weather tightness, even when faced with strong wind.
