Description
Die Erfindung betrifft ein Beschattungssystem gemäß dem Oberbegriff von Anspruch
1.The invention relates to a shading system according to the preamble of
In der Bau- und Fassadentechnik werden zunehmend Verglasungssysteme eingesetzt, die über die reine Verglasungsfunktion hinaus anspruchsvolle Aufgaben übernehmen. Es sind Systeme bekannt, mit denen das natürliche Sonnenlicht abgewiesen werden kann (Beschattung). Dies ist hauptsächlich in den Sommermonaten relevant. Daneben wurde auch in zunehmendem Umfang der Versuch unternommen, Verglasungssysteme in den Wintermonaten und in der Übergangszeit (Übergangsheizperiode) für die Raumheizung zu nutzen.In construction and facade technology, glazing systems are increasingly used the tasks beyond the mere glazing function take. There are known systems that use natural sunlight can be rejected (shading). This is mainly in the Summer months relevant. In addition, was increasingly the Attempted glazing systems in the winter months and in the Transitional period (transition heating period) to use for space heating.
Für die Beschattung eignen sich Lamellenjalousien, wie sie z.B. in der deutschen Offenlegungsschrift DE 39 04 763 A1 und in der europäischen Patentanmeldung EP 0 948 131 A1 beschrieben sind. For the shading lamellar blinds, as they are e.g. in the German Laid-open application DE 39 04 763 A1 and in the European patent application EP 0 948 131 A1 are described.
Es ist die Aufgabe der Erfindung, ein Verglasungssystem zur Verfügung zu stellen, mit dem sowohl die Beschattung als auch die Beheizung eines Raumes möglich ist.It is the object of the invention to provide a glazing system, with which both the shading and the heating of a room possible is.
Diese Aufgabe wird gelöst mit einem Beschattungssystem gemäß Anspruch 1.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Systems sind in den Unteransprüchen
beschrieben.This object is achieved with a shading system according to
Ein erfindungsgemäßes Beschattungssystem weist eine innere Scheibe und eine äußere Scheibe auf, die einen ersten Scheibenzwischenraum bilden, und eine im ersten Scheibenzwischenraum angeordnete Lamellenjalousie mit um ihre Längsachse verschwenkbaren und wahlweise zusätzlich heb- und senkbaren Lamellen, mit der das Innere eines Raumes beschattbar ist. Mindestens eine der Scheiben - bevorzugt die innere Scheibe - ist elektrisch beheizbar.An inventive shading system has an inner disc and a outer disc, which form a first disc space, and one in the first disc space arranged slat blind with around its longitudinal axis pivotable and optionally additionally raised and lowered blades, with which the interior of a room can be shaded. At least one of the discs - Preferably, the inner pane - is electrically heated.
Erfindungsgemäß sind die Lamellen verschwenkbar und wahlweise zusätzlich heb- und senkbar. Diese Ausgestaltung trägt der Erfahrung Rechnung, daß sich in der Praxis praktisch jeder Benutzer einer Jalousie verschwenkbare Lamellen wünscht, deren Heb- und Senkbarkeit jedoch nur in etwa 70 bis 80 % der Anwendungsfälle gefordert wird. Bei einer Jalousie ergibt sich ein Zustand maximaler Beschattung, wenn deren Lamellenpaket nach unten ausgefahren und die einzelnen Lamellen gegen die Sonne gedreht sind. Durch schrittweises Drehen der Lamellen kann die Beschattung wahlweise verringert werden, bis die Lamellen waagrecht stehen. Ausgehend von diesem Zustand ergibt ein Hochfahren der Lamellen nur noch eine geringfügige weitere Abnahme der Beschattung, die in der Praxis meist keine Rolle spielt. Ein Hochfahren der Lamellen hat meist nur den ästhetischen Gewinn, daß die waagrecht stehenden Lamellen aus dem Gesichtsfeld verschwinden.According to the invention, the slats are pivotable and optionally in addition raised and lowered. This embodiment takes into account the experience that In practice, practically every user of a blind pivotable slats wishes, however, their lifting and lowering ability only in about 70 to 80% of the applications is required. With a Venetian blind, a state of maximum results Shading when the disc pack is extended downwards and the individual slats are turned against the sun. By stepwise turning the fins can be selectively reduced to the shading until the slats standing horizontally. Starting from this state results in a booting the Slats only a slight further decrease in shading, the in The practice usually does not matter. A ramp up of the slats is usually only the aesthetic gain that the horizontal slats out of sight disappear.
Gemäß einer bevorzugten Ausführungsform ist die innere Scheibe aus zwei Einzelscheiben aufgebaut, wobei eine Einzelscheibe an den beschattbaren Raum und die andere Einzelscheibe an den ersten Scheibenzwischenraum angrenzt und die Einzelscheiben mit einer zwischen ihnen angeordneten Verbindungsschicht zu einer Verbundglaseinheit verbunden sind. Die Beheizung erfolgt bei dieser Ausführungsform durch in die Verbindungsschicht eingelassene elektrische Heizdrähte. Bei auf dem Markt befindlichen Produkten dieser Art sind die Einzelscheiben mit der Verbindungsschicht und den Heizdrähten so miteinander verbunden, daß sie mit dem bloßen Auge praktisch nicht zu erkennen sind. Die Herstellung erfolgt durch Aufeinanderlegen von elastischen Folien, bevorzugt aus PVB (Polyvinylbutyral), in die Heizdrähte eingebettet sind, und Scheiben aus Floatglas und einer nachfolgenden thermischen Behandlung dieses Verbundes unter Druck in einem Autoklaven.According to a preferred embodiment, the inner disc of two individual discs built, with a single pane to the shadable room and the other single disc is adjacent to the first disc space and the individual disks with a connecting layer arranged between them are connected to a laminated glass unit. The heating takes place at this embodiment by embedded in the connection layer electrical Heating wires. For products of this kind on the market, the Single discs with the connecting layer and the heating wires together connected, that they are virtually invisible to the naked eye. The Production takes place by stacking of elastic films, preferably from PVB (polyvinyl butyral), in which heating wires are embedded, and slices of float glass and a subsequent thermal treatment of this composite under Pressure in an autoclave.
Dieser Aufbau gibt dem Beschattungssystem die Eigenschaften von Verbundsicherheitsglas. Sicherheitsrelevant ist die Eigenschaft von Verbundglas, bei Schlageinwirkung nicht in kleine Stücke zu zerspringen. Zwar laufen entstehende Sprünge über die betroffene Einzelscheibe, die innere Scheibe wird jedoch durch die Verbindungsschicht weiter zusammengehalten und bleibt in ihrer Gesamtstruktur erhalten. Zwischen den Einzelscheiben kann ein Stabilisierungselement angeordnet sein, bevorzugt in Gestalt einer Schicht aus transparentem gehärteten Gießharz oder aus transparentem Kunststoff, beispielsweise aus PVB (Polyvinylbutyral). Diese Schicht verbindet die beiden Einzelscheiben und erweitert das System des Verbundsicherheitsglases.This construction gives the shading system the properties of laminated safety glass. Security property is the property of laminated glass, at Impact not to break into small pieces. Although running arise Jumps over the affected single disc, the inner disc is, however, through the tie layer continues to be held together and remains in its overall structure receive. Between the individual discs, a stabilizing element be arranged, preferably in the form of a layer of transparent cured Casting resin or of transparent plastic, for example of PVB (polyvinyl butyral). This layer connects the two single panes and expands the system of laminated safety glass.
Ausgehend von dem beschriebenen Aufbau mit aus zwei Einzelscheiben aufgebauter innerer Scheibe können die Einzelscheiben bei einer anderen bevorzugten Ausführungsform auch voneinander beabstandet sein und einen zweiten Scheibenzwischenraum bilden. Die Beheizung erfolgt bei dieser Ausführungsform durch eine elektrisch leitende Flächenbeschichtung, die auf derjenigen Oberfläche der an den beschattbaren Raum angrenzenden Einzelscheibe aufgebracht ist, die an den zweiten Scheibenzwischenraum angrenzt. Dadurch strahlt die durch die Beheizung erzeugte Wärme in Richtung auf das Innere des beschattbaren Raumes ab. Bevorzugt ist die Flächenbeschichtung eine Hartbeschichtung aus mit Fluor oder Indium dotiertem Zinnoxid.Based on the described structure with built from two individual discs inner disc may be the single disc in another preferred Embodiment also be spaced apart from each other and a second Make disk space. The heating takes place in this embodiment by an electrically conductive surface coating on top of that Surface of the adjoining the shadable space single disc applied is adjacent to the second disc space. This radiates the heat generated by the heating towards the interior of the shadable Room off. Preferably, the surface coating is a hard coating of fluorine or indium doped tin oxide.
Auch bei dieser Ausführungsform kann zwischen den Einzelscheiben ein Stabilisierungselement angeordnet sein, wobei ein ganz oder teilweise umlaufender Abstandhalter bevorzugt ist. Also in this embodiment can be a stabilizing element between the individual discs be arranged, with a completely or partially circumferential Spacer is preferred.
Bei allen beschriebenen Ausführungsformen kann die an den ersten Scheibenzwischenraum angrenzende Oberfläche der äußeren Scheibe eine wärmereflektierende Schicht tragen. Diese Ausführungsform ist besonders bevorzugt, weil dadurch Wärmeverluste durch Abstrahlung nach außen vermieden werden. Insbesondere wird auf diese Weise die durch die elektrische Heizung erzeugte Energie weitgehend vollständig dem beschattbaren Raum zugeführt. Die Nutzung dieser Energie beträgt 90 % oder mehr. Bevorzugt sind Weichbeschichtungen auf Edelmetallbasis, die mit dem Magnetronsputterverfahren hergestellt sind.In all the described embodiments, the at the first disc space adjacent surface of the outer pane is a heat-reflecting Wear layer. This embodiment is particularly preferred because This heat losses are avoided by radiation to the outside. Especially In this way it will be the one generated by the electric heater Energy largely completely fed to the shadable space. The use this energy is 90% or more. Preference is given to soft coatings based on precious metals, which are produced by the magnetron sputtering process.
Die Begriffe "gas" und "gasdicht" sollen sich im Rahmen dieser Beschreibung und auch in den Schutzansprüchen sowohl auf normale atmosphärische Luft als auch auf Schutzgase beziehen, die in der Verglasungstechnik zum Wärme- und/oder Schallschutz eingesetzt werden. Solche Schutzgase sind Edelgase wie Argon (Ar), Krypton (Kr) und Xenon (Xe) sowie Schwefelhexafluorid (SF6) oder Gemische davon.The terms "gas" and "gas-tight" should in the context of this description and in the protection claims relate both to normal atmospheric air and inert gases, which are used in the glazing technique for heat and / or sound insulation. Such protective gases are noble gases such as argon (Ar), krypton (Kr) and xenon (Xe) and sulfur hexafluoride (SF 6 ) or mixtures thereof.
Nachfolgend werden die Einsatzmöglichkeiten und Vorteile des erfindungsgemäßen Beschattungs- und Lichtlenksystems (kurz "System" genannt") weiter beschrieben.The possible uses and advantages of the shading and light-guiding system according to the invention ( " system" for short) are described below.
Der grundsätzliche Vorteil einer elektrischen Heizung mit Fensterscheiben liegt in der schnellen Verfügbarkeit der Wärmeenergie. Das System hat - im Gegensatz zu allen anderen Heizungsarten - praktisch keine Verzögerungszeit. Die Wärme ist nicht nur schnell verfügbar, sondern entsteht auch in einer Weise, die herkömmliche Heizkörper (Radiatoren) überflüssig macht. Beides dient dem Wohlgefühl und der Lebensqualität des Bewohners.The basic advantage of an electric heater with window panes lies in the rapid availability of heat energy. The system has - in contrast to all other types of heating - practically no delay time. The heat Not only is it quickly available, it also emerges in a way that is conventional Radiator (radiators) makes unnecessary. Both serve the well-being and the quality of life of the resident.
Ein weitere Vorteil besteht in der Möglichkeit, durch den Einbau eines erfindungsgemäßen Systems als Fenster oder in eine Fassade die klimatischen Bedingungen beeinflussen zu können. In den Sommermonaten kann mit der innenliegenden Lamellenjalousie der Wärme- und Lichtfluß gesteuert werden. In den Wintermonaten und in der Übergangsheizperiode kann mit der beheizbaren Scheibe Wärme erzeugt werden, wobei deren schnelle Verfügbarkeit bereits erwähnt wurde. In der Übergangsheizperiode kommt besonders eine Zusatzheizung in Frage. Diese Wärme steht dort im Bauwerk zur Verfügung, wo klassischerweise die größten Wärmeverluste auftreten.Another advantage is the possibility of incorporating an inventive Systems as windows or in a facade the climatic conditions to be able to influence. In the summer months can be with the inside Venetian blind the heat and light flux are controlled. In the Winter months and in the transitional heating season can be heated with Disk heat are generated, with their rapid availability already mentioned has been. In the transitional heating period is especially an additional heating in question. This heat is available in the building, where classically the largest heat losses occur.
Durch die Scheibenbeheizung wird die Kondensation von Feuchtigkeit und das Beschlagen der Glasflächen verhindert. Die erzeugte Wärmeenergie entsteht als reine Wärmestrahlung und ereicht den Raum entweder auf direktem Wege oder nach Reflexion an der bevorzugt eingesetzten wärmereflektierenden Schicht der äußeren Scheibe. Auf Konvektion wird also weitgehend verzichtet. Die Beheizung erfolgt deshalb praktisch ohne Zugluft und ohne Transport von Staubpartikeln und leistet einen Beitrag zur Raumhygiene. Dieser Effekt ist besonders im Bereich der Medizin bedeutsam, beispielsweise in Operationssälen, Sterilräumen und Arztpraxen. Er spielt außerdem eine Rolle in Reinsträumen, in denen mikroelektronische Produkte hergestellt werden.Due to the disc heating, the condensation of moisture and the Fogging of the glass surfaces prevented. The generated heat energy arises as pure heat radiation and reaches the room either directly or after reflection on the preferably used heat-reflecting layer of outer disc. Convection is therefore largely dispensed with. The heating takes place therefore practically without drafts and without transport of dust particles and makes a contribution to room hygiene. This effect is especially in the field of Medicine is important, for example in operating rooms, sterile rooms and medical practices. He also plays a role in clean rooms, where microelectronic Products are manufactured.
