Abstract

The solar heat collector roofing material normally consists of transparent material, which does not harmonise with other houses in the neighbourhood. A coloured structural material is therefore used, which is transparent only to wavelengths of over 500 nm, i.e. the long waves. Material such as red acrylic glass is suitable for this purpose and reflects much less than transparent material. This roofing blends in well ith the normal red roof tiles of houses.

Description

Die Erfindung bezieht sich auf Solar-Kollektor-DachabdeckungenThe invention relates to solar collector roof coverings

aus strukturiertem, temperaturbeständigem und wärmestrahldurchlässigem Material.made of structured, temperature-resistant and heat-radiation-permeable Material.

Abdeckungen für Flach- oder konzentrierende Solar-Kollektoren sind aus klarsichtig-transparentem Material wie Glas, Acrylglas und sonstigen durchsichtigen Kunststoffen bekannt. Sie wurden bisher so klar und durchsichtig wie möglich gehalten, waren also transparent für alle Wellenlängen des Lichtes.Covers for flat or concentrating solar collectors are made of clear, transparent material such as glass, acrylic glass and other transparent materials Plastics known. So far they have been kept as clear and transparent as possible, were therefore transparent for all wavelengths of light.

Diese optisch durchsichtigen Solar-Ilollektor-Dachabdeckungen waren aber sehr schwer in die Gebäudedachflächen zu intearieren. Es wurde versucht, in Form von Bauelementen, die aussahen wie Dachfenster, die Kollektoren in die Dachhaut zu integrieren.These optically see-through solar collector roof covers were but very difficult to integrate into the building roof surfaces. An attempt was made in Form of building elements that looked like skylights, the collectors in the roof cladding to integrate.

Diese Lösungen waren aber alle nur teilweise und in kleineren Flächen zufriedenstellend.However, these solutions were all only partially and in smaller areas satisfactory.

Auch die totale Abdeckung des Daches mit durchsichtigem Material ist optisch wenig befriedigend, da die ganze Unterkonstruktion sichtbar ist und damit das Dach nicht mit den umgebenden Nachbarhäusern harmonisiert. Schwierigkeiten bei den Bauämtern, Nachbarn, Landschaftsschutz usw. sind daher an der Tagesordnung und erschweren die Verbreitung der Solartechnik allgemein.Also the total covering of the roof with transparent material is Visually unsatisfactory because the entire substructure is visible and thus the roof does not harmonize with the surrounding neighboring houses. Difficulties with the building authorities, neighbors, landscape protection, etc. are therefore the order of the day and complicate the spread of solar technology in general.

Der Erfindung liegt die Aufgabe zugrunde, eine Dachabdeckung der eingangs genannten Art zu schaffen, die ohne bedeutenden Verlust an Energiegewinnung der üblichen Bebauung anpaßbar ist.The invention is based on the object of providing a roof covering of the initially mentioned called type to create that without significant loss of energy production of the customary development is adaptable.

Erfindungsgemäß wird. diese Aufgabe dadurch gelöst, daß an sich bekannte farbige Baumaterialien verwendet werden, die für Weller längen > 500 nm durchlässig sind.According to the invention. this object is achieved in that known per se colored building materials are used that are permeable to wavelengths> 500 nm are.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.Further refinements of the invention are set out in the subclaims contain.

Der mit der Erfindung erzielbare Vorteil besteht darin, daß farbige Abdeckmaterialien verwendet werden, die in Struktur und Oberfläche dem üblichen und gewünschten Dachaussehen angepaßt werden können, so daß sich im Ortsbild eine einheitliche Dachharmonie ergibt, die auch von den Bauämtern und den Landschaftsschützern nicht angefochten werden kann.The advantage achieved with the invention is that colored Covering materials are used that have the usual structure and surface and the desired roof appearance can be adjusted so that there is a uniform roof harmony results, also from the building authorities and the landscape conservationists cannot be challenged.

Zudem ergibt sich eine wesentliche Vereinfachung beim Einbau von Solaranlagen, da sie auf diese Weise nicht mehr genehmigungspflichtig sind. Es erfolgt ja keine äußere Veränderung des Gebäudes. Die Kollektoren bleiben unsichtbar. Dies hat auch den Vorteil, daß die Kollektorenfläche ohne behördliche Einschränkung auf das gewünschte Ausmaß in das Dach eingebaut werden kann.In addition, there is a significant simplification when installing solar systems, because in this way they no longer require approval. There is none external change in the building. The collectors remain invisible. This also has the advantage that the collector surface can be adjusted to the desired without any regulatory restrictions Extent can be built into the roof.

Es hat sich gezeigt, daß die Strahlung im sichtbaren und ultrakurzwelligen Bereich für die Wärmegewinnung von geringer Bedeutung sind, da sie nur einen kleinen Teil der Sonnenstrahlung ausmachen. Zudem sind sie in hohem Maße reflektierbar und es bedarf deshalb einer aufwendigen Technik, um die Reflektion in tragbaren Grenzen zu halten. Desweiteren ist die Strahlung im W-Bereich für die Lebensdauer der Materialien, besonders von Kunststoffen, nur von Nachteil. Besonders wichtig für die Wärmegewinnung ist der langwellige Bereich, der ab 500 nm beginnt. In der modernen Technik gibt es Baustoffe, die der üblichen Dachfärbungen angepaßt sind und für Wellenlängen ab 500 nm genügend durchlässig sind, z.B. rotes Acrylglas.It has been shown that the radiation in the visible and ultra-short wave Area for heat recovery are of little importance as they are only a small one Make up part of the solar radiation. In addition, they are highly reflective and therefore, complex technology is required in order to keep the reflection within acceptable limits to keep. Furthermore, the radiation in the W range is important for the service life of the materials, especially of plastics, only a disadvantage. Particularly important for heat recovery is the long-wave range that begins at 500 nm. In modern technology there are there are building materials that are adapted to the usual roof colors and for wavelengths are sufficiently permeable from 500 nm, e.g. red acrylic glass.

Zudem haben Messungen ergeben, daß die Reflektion der farbigen, insbesondere der roten Kunststoffplatten bei schrägem Einfallswinkel der Sonnenstrahlen, also bei niedrigem Sonnenstand im Winter und in den Vormittags- und Nachmittagsstunden, wesentlich geringer ist als bei klarsichtigem Material. Auf diese Weise ist der ärmegewinn bei bestimmten farbigen Abdeckungen über die gesamte Tageszeit hinweg höher als bei klarsichtigen Kollektorabdeckungen.In addition, measurements have shown that the reflection of the colored, in particular of the red plastic plates at an oblique angle of incidence of the sun's rays, so when the sun is low in winter and in the morning and afternoon hours, is much lower than with clear material. In this way is the Heat gain with certain colored covers over the entire time of the day higher than with transparent collector covers.

Durch die Verwendung von geeigneten Kunststoffen können die Platten flächenmäßig um ein Vielfaches größer angefertigt werden als die bekannten Ziegel- oder Betondachplatten.By using suitable plastics, the panels can be made many times larger in area than the well-known brick or concrete roof panels.

Dadurch ergibt sich eine rationellere und auch preiswertere Dacheindeckung. Durch die spezielle Ausbildung der Abschlußkanten können diese farbigen Solar-Kollektor-Dachplatten zusammen mit normalen, bekannten Ziegel- oder Betondachplatten verwendet werden. Selbstverständlich können sie auch ausschließlich als Dachabdeckung Verwendung finden, also auch über Dachflächen, unter denen sich keine Solar-Kollektoren befinden.This results in a more efficient and also cheaper roof covering. Due to the special design of the end edges, these colored solar collector roof panels can be used together with normal, well-known tile or concrete roof panels. Of course, they can also be used exclusively as a roof cover, thus also over roof areas under which there are no solar collectors.
