Description
Seit Jahrzehnten werden große Anstrengungen, in letzter Zeit sogar noch verstärkt, unternommen, um die Sonneneinstrahlung für die Erzeugung elektrischer Energie und Wärmeenergie auszunutzen. Alle bisher bekannt gewordenen Photovoltaiksysteme haben trotz des laufend verbesserten Wirkungsgrades noch nicht zu einem technischen Durchbruch geführt, weil der bei der Erzeugung elektrischer Energie mit herkömmlichen Photovoltaiksystemen zu treibende Aufwand im Vergleich zu dem bei der Erzeugung elektrischer Energie mit Kraftwerken zutreibenden Aufwand nach wie vor unverhältnismäßig größer ist.Great efforts have been made for decades, in the latter Time even intensified, taken to the Solar radiation for the generation of electrical energy and utilize thermal energy. All known so far become photovoltaic systems despite the ongoing not yet improved efficiency technical breakthrough because of the Generating electrical energy using conventional Effort compared to photovoltaic systems that with the generation of electrical energy Expenses incurred by power plants continue to be is disproportionately larger.
Auch mit einem sogenannten Photovoltaik-Hybridkollektor, der in Kombination Photovoltaiksysteme und Mittel zur unmittelbaren Wärmeaufnahme, sogenannte Solarkollektoren umfaßt, konnte ein überzeugender wirtschaftlicher Erfolg nicht erzielt werden. Dies mag an der sehr aufwendigen Konstruktion der Hybridkollektoren liegen. Bei einem bekannten Hybridkollektor (Prospektblatt Spektrum, Der Photovoltaik-Hybrid-Kollektor der Fa. Dahlmann & Janetzko, Gewerbeschulstraße 3, 42287 Wuppertal) sind nämlich in einer Rahmenkonstruktion unter einer Glasplatte in einem hochtransparenten und witterungsbeständigen Kunststoff Solarzellen aus kristallinem Silizium gehalten. Die Solarzellen liegen auf einem Aluminiumwärmeabsorberprofil mit Kupferrohren auf, das rückseitig mit Dämmaterial wärmeisoliert ist und eine Aluminiumrückwand aufweist. Während die elektrische Energie von den Photovioltaik-Solarmodulen geliefert wird, wird die Wärmeenergie mit einem Wärmeträgermedium, das über die Kupferrohre fließt, abgenommen. Wegen der unerwünschten Wärmeentwicklung der kristallinen Solarzellen verlieren diese mit steigenden Temperaturen ihre Effektivität, wodurch die Praxistauglichkeit eines solchen konstruktiv aufwendigen Hybridkollektors in Frage gestellt wird. Ein solcher Hybridkollektor kann zwar auf einer vorhandenen Dachdeckung montiert werden, doch sind sein hohes Gewicht und seine aus Glas bestehende, bruchempfindliche Oberfläche problematisch. Auch wirkt er als Fremdkörper und stört unter ästhetischen Gesichtspunkten das Gesamterscheinungsbild einer damit bestückten Dachdeckung oder Wandverkleidung.Even with a so-called photovoltaic hybrid collector, which in combination photovoltaic systems and means for immediate heat absorption, so-called solar collectors could be a convincing economic success cannot be achieved. This may be due to the very elaborate Construction of the hybrid collectors lie. At a known hybrid collector (prospectus spectrum, Der Photovoltaic hybrid collector from Dahlmann & Janetzko, Gewerbeschulstraße 3, 42287 Wuppertal) namely in a frame construction under one Glass plate in a highly transparent and weatherproof plastic solar cells crystalline silicon. The solar cells are lying on an aluminum heat absorber profile with copper pipes on, which is thermally insulated on the back with insulating material and has an aluminum back wall. While the electrical Energy supplied by the photovoltaic solar modules heat energy with a heat transfer medium, that flows over the copper pipes. Because of the undesirable heat development of the crystalline Solar cells lose them with increasing temperatures their effectiveness, which makes the practicality of a such a constructively complex hybrid collector in question is provided. Such a hybrid collector can be an existing roof covering, but are its heavy weight and its glass, breakable surface problematic. He also works as a foreign body and disturbs under aesthetic Aspects the overall appearance of a equipped roof covering or wall cladding.
Darüber hinaus sind Photovoltaik-Solarmodule bekannt (EP 0 625802), die aus einer durch Abkantungen versteiften Trägerplatte aus Metallblech und einer darauf befestigten, flexiblen Verbundfolie bestehen, die ihrerseits aus einer Trägerfolie aus Edelstahl, einer Schicht mit Solarzellen und einer transparenten Deckschicht besteht. Solche Photovoltaik-Solarmodule lassen sich mittels die Abkantungen erfassender Klammern auf einer Dachunterkonstruktion befestigen.In addition, photovoltaic solar modules are known (EP 0 625802), which consists of a bevel stiffened carrier plate made of sheet metal and one on it attached, flexible composite film that in turn from a carrier foil made of stainless steel, one Layer with solar cells and a transparent Cover layer exists. Such photovoltaic solar modules can be determined using the brackets attach to a roof substructure.
Der Erfindung liegt die Aufgabe zugrunde, eine mit einem Photovoltaiksystem bestückbare Dachdeckung beziehungsweise Wandverkleidung zu schaffen, die bei einem ästhetisch ansprechenden Erscheinungsbild mit geringem technischen Aufwand herstellbar ist und bei der das Photovoltaiksystem mit gutem Wirkungsgrad arbeitet. The invention has for its object one with Roof covering that can be equipped with a photovoltaic system or to create wall cladding that at with an aesthetically pleasing appearance low technical effort can be produced and at the photovoltaic system works with good efficiency.
Diese Aufgabe wird bei einer Dachdeckung oder Wandverkleidung mit selbsttragenden Metallblechpaneelen mit außenseitig aufgebrachten und durch eine äußere Deckschicht aus lichtdurchlässigem Kunststoff geschützten Photovoltaik-Solarmodulen, insbesondere aus amorphem Silizium gelöst, bei der ein System mit geregelter Wärmeab- und/oder -zufuhr unterseitig an der Metallblechpaneele in wärmeleitendem Kontakt gehalten ist.This task is at a roofing or Wall cladding with self-supporting sheet metal panels with applied on the outside and by an outside Protected cover layer made of translucent plastic Photovoltaic solar modules, in particular made of amorphous Silicon solved using a system with regulated Heat dissipation and / or supply on the underside of the Sheet metal panels kept in heat-conducting contact is.
Die erfindungsgemäße Dachdeckung beziehungsweise Wandverkleidung genügt auch höheren ästhetischen Ansprüchen insofern, als die Ausrüstung der Metallblechpaneele mit Photovoltaik-Solarmodulen und dem unterseitigen System mit geregelter Wärmeab- und/oder -zufuhr optisch kaum in Erscheinung tritt, so daß so bestückte Metallblechpaneele von solchen Metallblechpaneelen, die diese Ausrüstung nicht haben, sich praktisch nicht unterscheiden. Eine Dachdeckung oder Wandverkleidung aus gemischt erfindungsgemäß ausgerüsteten Metallblechpaneelen und solchen ohne eine solche Ausrüstung hat deshalb ein ästhetisch ansprechendes einheitliches Erscheinungsbild.The roof covering according to the invention, respectively Wall cladding also satisfies higher aesthetic requirements Claims insofar as the equipment of the Sheet metal panels with photovoltaic solar modules and the underside system with regulated heat dissipation and / or -supply optically hardly appears, so that populated sheet metal panels of such Sheet metal panels that do not have this equipment, practically do not differ. A roof covering or Wall covering from mixed according to the invention equipped sheet metal panels and those without one such equipment therefore has an aesthetic attractive uniform appearance.
Da die Dachdeckung beziehungsweise Wandverkleidung für die besondere Ausrüstung keine eigene Tragkonstruktion benötigt, sondern die selbsttragenden Metallblechpaneele als Träger für die Ausrüstung fungieren, sogar aussteifend auf eine Unterkonstruktion wirken, ist der mit der Herstellung solcher Dachdeckung verbundene konstruktive Aufwand gering. Since the roof covering or wall covering for the special equipment does not have its own supporting structure needed, but the self-supporting sheet metal panels act as carriers for the equipment, even act stiffening on a substructure associated with the manufacture of such roofing constructive effort low.
Die Eigenschaft der Metallblechpaneele, selbsttragend zu sein und aussteifend zu wirken, läßt sich bei entsprechender Materialdicke des Metallbleches mit Aufkantungen der Längsränder sehr einfach erreichen. Diese Aufkantungen können dann auch zusammen mit aufsteckbaren Klammern und Abdeckleisten zur regensicheren Verbindung benachbarter Metallblechpaneelen benutzt werden.The property of sheet metal panels, self-supporting too can be and to act stiffening, with appropriate material thickness of the metal sheet with Reach up the edges of the longitudinal edges very easily. These backsplashes can also be used together with clip-on clips and cover strips for rainproof connection of adjacent sheet metal panels to be used.
Vorzugsweise bilden die Photovoltaik-Solarmodule mit ihrer Deckschicht und einer Trägerfolie aus einem Material mit einem guten Wärmeleitwert flexible Verbundfolien, die mit ihrer Trägerfolie unmittelbar an dem Metallblechpaneel anliegen. Mit einer solchen Verbundfolie ist die Herstellung der einzelnen Elemente für die Dachdeckung durch Auflaminieren der Verbundfolie auf ein Metallblechband und anschließendes Ablängen und Profilieren großtechnisch möglich.The photovoltaic solar modules preferably also form its top layer and a carrier film from one Material with a good thermal conductivity flexible Composite films with their carrier film immediately fit the sheet metal panel. With one Composite film is the production of the individual elements for roofing by laminating the composite film on a sheet metal strip and subsequent cutting and Profiling possible on an industrial scale.
Das System mit der geregelten Wärmeab- und/oder -zufuhr kann - neben der unmittelbaren Gewinnung von Wärmeenergie - auch dazu dienen, eine vereiste oder mit Schnee bedeckte Dacheindeckung oder Wandverkleidung freizumachen, um die Sonneneinstrahlung wieder besser zu den Solarzellen durchzulassen, oder die Temperatur der Solarzellen derart einzustellen, daß diese mit optimalen Wirkungsgrad arbeiten.The system with regulated heat removal and / or supply can - in addition to the direct production of thermal energy - also serve an icy or covered with snow covered roof covering or wall cladding to clear the sun to better again let the solar cells through, or the temperature of the Adjust solar cells so that they with optimal Work efficiency.
Das System mit der geregelten Wärmeab- und/oder -zufuhr wird vorzugsweise von einem wärmeträgerdurchströmten Leitungssystem mit einem temperaturgeführten Kühl- und/oder Wärmeaggregat gebildet. Es versteht sich, daß das Leitungssystem mit möglichst geringem Wärmeübergangswiderstand an der Rückseite der Metallblechpaneele anzubringen ist.The system with regulated heat removal and / or supply is preferably flowed through by a heat transfer medium Line system with a temperature-controlled cooling and / or heating unit formed. It is understood that the pipe system with as little as possible Heat transfer resistance at the back of the Sheet metal panels must be attached.
Für die unmittelbare Wärmegewinnung mit dem System mit geregelter Wärmeab- und/oder -zufuhr ist von Vorteil, wenn die Metallblechpaneele zusammen mit diesem System unterseitig von Wärmedämmaterial abgedeckt ist. In einem solchen Fall kann die im allgemeinen notwendige dach- oder wandseitige Wärmedämmung für das Gebäude schwächer dimensioniert sein oder sogar entfallen, wenn dies bei der Dimensionierung der Wärmedämmung der Elemente für Metallblechpaneele berücksichtigt wird.For immediate heat generation with the system regulated heat removal and / or supply is advantageous, if the sheet metal panels together with this system is covered on the underside by thermal insulation material. In one In such a case, the generally necessary roof or weaker wall insulation for the building be dimensioned or even omitted if this at the dimensioning of the thermal insulation of the elements for Sheet metal panels is taken into account.
Als äußere Deckschicht für das Photovoltaik-Solarmodul eignet sich z. B. eine PVF-Folie. Eine solche Folie ist nicht nur transparent und witterungsbeständig, sondern auch kratz- und reißfest. Ein damit geschütztes Photovoltaik-Solarmodul auf einer Metallblechpaneele kann dann auch begangen werden, ohne daß dadurch die auflaminierten Photovoltaikzellen Schaden nehmen.As an outer cover layer for the photovoltaic solar module is suitable for. B. a PVF film. Such a slide is not only transparent and weatherproof, but also scratch and tear resistant. A protected with it Can photovoltaic solar module on a sheet metal panel then also be committed without the damage to laminated photovoltaic cells.
Als Material für die Trägerfolie eignet sich eine Edelstahlfolie. Das Metallblechpaneel ist vorzugsweise kaltgewalztes, beidseitig korrosionsgeschütztes Stahlblech.A is suitable as the material for the carrier film Stainless steel foil. The sheet metal panel is preferred cold rolled, corrosion protected on both sides Sheet steel.
Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Im einzelnen zeigen:In the following the invention is based on a Exemplary embodiment drawing closer explained. In detail show:
Fig. 1 eine Dachdeckung in schematischer Darstellung im Querschnitt ausschnittweise, Fig. 1 shows a roof covering in a schematic representation in partial cross section,
Fig. 2 ein Metallblechpaneel für eine Dachdeckung nach Fig. 1 mit einem außenseitig auflaminierten Photovoltaik-Solarmodul im Querschnitt ausschnittweise und Fig. 2 shows a metal sheet panel for a roof covering according to Fig. 1 with an externally laminated photovoltaic solar module in cross section and
Fig. 3 zwei miteinander verbundene Metallblechpaneele für eine Dachdeckung in einer zu Fig. 1 abgewandelten Ausführung im Querschnitt. Fig. 3 two interconnected sheet metal panels for a roof covering in a modified version of FIG. 1 in cross section.
Auf einer Dachunterkonstruktion aus Sparren 1, 2 und Querlatten 3 ist eine Dachdeckung aus Metallblechpaneelen 4, 5, 6 angeordnet. An ihren Längsrändern weisen die Metallblechpaneele 4, 5, 6 Aufkantungen 4a, 5a, 5b, 6a auf, die von U-förmig profilierten Abdeckleisten 7, 8 überdeckt sind und mittels der auch als Klammer wirkenden Abdeckleisten 7, 8 und Schrauben 9, 10 an der Dachunterkonstruktion 1, 2, 3 befestigt sind.A roof covering made of sheet metal panels 4 , 5 , 6 is arranged on a roof substructure composed of rafters 1 , 2 and crossbars 3 . At their longitudinal edges 5 5 6, the sheet metal panels 4, 5, 6 upstands 4 a, a, b, a, which U-shaped profile cover strips 7 are covered 8 and by means of which also acts as a clamp cover strips 7, 8 and screws 9 , 10 are attached to the roof substructure 1 , 2 , 3 .
Für die Erfindung ist es unwichtig, wie die Unterkonstruktion 1, 2, 3 im einzelnen aussieht. Auch können die Metallblechpaneele 4, 5, 6 und die sie haltenden Profile 7, 8 eine andere Form haben. So können die Metallblechpaneele 4, 5, 6 auch mit ihren benachbarten Längsrändern einander überlappen, so daß Abdeckleisten 7, 8 und Klammern überflüssig sind.It is unimportant for the invention what the substructure 1 , 2 , 3 looks like in detail. The metal sheet panels 4 , 5 , 6 and the profiles 7 , 8 holding them can have a different shape. Thus, the metal sheet panels 4 , 5 , 6 can overlap each other with their adjacent longitudinal edges, so that cover strips 7 , 8 and clips are unnecessary.
Die einzelnen Metallblechpaneele 4, 5, 6 haben den in Fig. 2 dargestellten Aufbau. Das Metallblechpaneel 5 ist beidseitig korrosionsgeschützt. Seine Materialdicke insbesondere unter Berücksichtigung der Aufkantungen 4a, 5a, 6a, 7a ist ausreichend, um selbsttragend zu sein und ggf. aussteifend auf die Unterkonstruktion zu wirken. The individual sheet metal panels 4 , 5 , 6 have the structure shown in FIG. 2. The metal sheet panel 5 is protected against corrosion on both sides. Its material thickness, in particular taking into account the upstands 4 a, 5 a, 6 a, 7 a, is sufficient to be self-supporting and, if necessary, to have a reinforcing effect on the substructure.
Diese Ausführung reicht auch aus, um alle äußeren Belastungen, auch die des Begehens, aufnehmen zu können. Das Metallblechpaneel 5 trägt auf seiner Außenseite ein Photovoltaik-Solarmodul 11 in Form einer in verschiedenen Breiten vollflächig aufgebrachten flexiblen Verbundfolie, die durch eine aufkaschierte Deckschicht 12 aus lichtdurchlässigem Kunststoff, z. B. PFV geschützt ist, der möglichst reiß- und kratzfest sein soll. Da die aufgebrachte Verbundfolie das Metallblechpaneel 5 fast vollständig bedeckt, ergibt sich vollflächig ein einheitliches Erscheinungsbild, insbesondere wenn der Farbton demjenigen der Verbundfolie entspricht. Rückseitig trägt das Metallblechpaneel 5 ein System 13 zut geregelten Wärmeab- und/oder -zufuhr.This version is also sufficient to be able to absorb all external loads, including those from walking. The metal sheet panel 5 carries on its outside a photovoltaic solar module 11 in the form of a flexible composite film applied over the entire surface in various widths, which is covered by a laminated cover layer 12 made of translucent plastic, e.g. B. PFV is protected, which should be as tear and scratch resistant as possible. Since the applied composite film almost completely covers the metal sheet panel 5 , a uniform appearance results over the entire surface, especially if the color tone corresponds to that of the composite film. On the back, the sheet metal panel 5 carries a system 13 for regulated heat removal and / or supply.
Das Photovoltaik-Solarmodul 11 in Form einer flexiblen Verbundfolie besteht aus einem Trägermaterial 11a, insbesondere einer Edelstahlfolie, einer darauf angeordneten Reflektorschicht 11b und in drei Schichten 11c, 11d, 11e angeordnete Solarzellen aus amorphem Silizium. Jede dieser Schichten 11c, 11d, 11e ist auf eine andere Wellenlänge des Sonnenlichtes abgestimmt. Solche Folien werden vom Hersteller in integrierter Serienverschaltung der einzelnen Schichten 11c, 11d, 11e dem Anwender zur Verfügung gestellt. Es versteht sich, daß die in Fig. 2 dargestellten Proportionen nicht der Wirklichkeit entsprechen. Insbesondere ist die Dicke des Photovoltaik-Solarmoduls 11 wesentlich kleiner als dargestellt im Verhältnis zur Dicke des Metallblechpaneels 5.The photovoltaic solar module 11 in the form of a flexible composite film consists of a support material 11 a, in particular a stainless steel foil, having thereon a reflector layer 11 b and in three layers 11 c, 11 d, 11 e disposed amorphous silicon solar cells. Each of these layers 11 c, 11 d, 11 e is tuned to a different wavelength of sunlight. Such films are made available to the user by the manufacturer in an integrated series connection of the individual layers 11 c, 11 d, 11 e. It is understood that the proportions shown in Fig. 2 do not correspond to reality. In particular, the thickness of the photovoltaic solar module 11 is significantly smaller than shown in relation to the thickness of the sheet metal panel 5 .
Das System 13 zur geregelten Wärmeab- und -zufuhr ist rückseitig an dem Metallblechpaneel 5 angebracht. Es besteht im wesentlichen aus einem Leitungssystem, das gut wärmeleitend mit dem Metallblechpaneel 5 verbunden ist. Es ist von einem Wärmeträgermedium durchströmt. Eine Regeleinrichtung sorgt dafür, daß in dem Leitungssystem erwärmtes Wasser einem Brauchwasserbehälter oder durch eine Heizeinrichtung erwärmtes Wasser dem Leitungssystem zur Enteisung der Metallblechpaneele 5 oder zur Einstellung der Temperatur der Photovoltaik-Solarmodule 11 für einen optimalen Wirkungsgrad zugeführt wird.The system 13 for regulated heat removal and supply is attached to the rear of the metal sheet panel 5 . It essentially consists of a line system which is connected to the metal sheet panel 5 with good thermal conductivity. A heat transfer medium flows through it. A control device ensures that water heated in the line system is supplied to a process water tank or water heated by a heating device to the line system for defrosting the metal sheet panels 5 or for adjusting the temperature of the photovoltaic solar modules 11 for optimum efficiency.
Für die Herstellung der mit Photovoltaikmodulen 11 bestückten Metallblechpaneele 5 wird von Rollen korrosionsgeschütztes Metallband abgewickelt und abgelängt. Insbesondere nach Anbringen der Aufkantungen 4a, 5a, 5b, 6a wird das Photovoltaik-Solarmodul 11 in Form der Verbundfolie auf die Metallblechpaneele aufgebracht.For the production of the metal sheet panels 5 equipped with photovoltaic modules 11 , corrosion-protected metal strip is unwound from rolls and cut to length. In particular after attaching the upstands 4 a, 5 a, 5 b, 6 a, the photovoltaic solar module 11 is applied to the sheet metal panels in the form of the composite film.
Während diese Einzelanfertigung sich mit einfachen Mitteln durchführen läßt, ist alternativ auch eine großtechnische Herstellung mit entsprechenden Maschinen möglich, bei der die Verbundfolie z. B. von der Rolle auf das Band auflaminiert wird und dann vor oder nach dem Ablängen die Abkantungen angebracht werden. Auch die Abkantungen können im Durchlauf geformt werden.While this one-off production is simple Lets carry out is alternatively one large-scale production with appropriate machines possible, in which the composite film z. B. from the role the tape is laminated and then before or after Cut the bends to length. Also the Bends can be formed in one pass.
Die wesentlichen Unterschiede beim Ausführungsbeispiel der Fig. 3 bestehen darin, daß dachseitig das Solarkollektormodul 13 mit Wärmedämmaterial 15 abgedeckt ist und sämtliche Elemente 5, 11, 13, 15 in kastenartigen Verkleidung 16 untergebracht sind. Das erleichtert die Montage im Vergleich zu einer separaten Montage von bestückten Metallpaneelen und Wärmedämmung. Außerdem ist die Befestigung an der Dachunterkonstruktion 1, 2,3 anders gestaltet. Mit Schrauben 9, 10 an der Dachunterkonstruktion 1, 2,3 befestigte, im wesentlichen im Profil U-förmige Klammern 17, 18 umgreifen mit zurückgebogenen Schenkelenden die Ränder der Aufkantungen 5a, 5b, 16a, 16b der benachbarten Stahlblechpaneelen 5 und der Verkleidungen 16. Auf den Klammern 17, 18 sind als Abdeckung U-förmig profilierte Leisten 19, 20 geklemmt.The main differences in the embodiment of FIG. 3 are that the solar collector module 13 is covered on the roof side with thermal insulation material 15 and all elements 5 , 11 , 13 , 15 are housed in box-like cladding 16 . This makes assembly easier compared to separate assembly of assembled metal panels and thermal insulation. In addition, the attachment to the roof substructure 1 , 2 , 3 is designed differently. With screws 9 , 10 attached to the roof substructure 1 , 2 , 3 , substantially U-shaped brackets 17 , 18 encompass the edges of the upstands 5 a, 5 b, 16 a, 16 b of the adjacent steel sheet panels 5 and the fairings 16 . On the clamps 17 , 18 , strips 19 , 20 with a U-shaped profile are clamped as a cover.
