Abstract

It is known to load absorber roof sheets with a liquid at an elevated or a reduced pressure. The disadvantage of elevated-pressure operation resides in the required increased strength of bonding of two cover plates to an intermediate mounting layer. In mats operated in the reduced-pressure region, air bubbles readily occur in the region of the inter layer, an air cavity layer likewise being formed, partially by downward diffusion. In order to combine the advantages of pressure application, namely prevention of cavity layers, with the advantage of reduced-pressure operation, it is proposed according to the invention that the collector (1) be supplied with a carrier liquid which, by means of a corresponding pump (4), is given a flow pressure which is somewhat higher than the resistance in the roof skin collector system (1), and a flap system (7) be opened on the delivery downpipe side (6) at a desired height, preferably after somewhat more than 2 m, and is intermittently opened by a counterweight or automatic control elements and accordingly produces a reduced pressure in the mat system (1). <IMAGE>

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Kollektor-Dachbahnen-System zur Vermeidung von Luftblasen Es ist bekannt, Absorber-Dachbahnen mit einer Flüssigkeit zu beaufschlagen, die im Unter- oder Überdruck arbeitet."Collector roof membrane system to avoid air bubbles It is known to apply a liquid to absorber roofing membranes, which in the lower or overpressure is working.

Der Nachteil einer im ueberdruck beaufschlagten Wärme-Absorptionsmatte liegt in der notwendigen erhöhten Festigkeitseinbindung zweier Deckplatten an die Zwischenlagerschicht.The disadvantage of a heat absorption mat subjected to excess pressure lies in the necessary increased strength integration of two cover plates on the Intermediate layer.

Im Unterdruckbereich gefahrene Matten erhalten leicht im Bereich der Zwischenschicht Luftblasen, und teilweise wird durch Diffusion nach unten ebenfalls eine Luftlunkerschicht gebildet.Mats driven in the negative pressure area easily get in the area of the Interlayer air bubbles, and partly through diffusion downwards as well a layer of air voids is formed.

Um die Vorteile der Druckbeaufschlagung - zur Verhinderung von Lunkerschichten - zu verbinden, jedoch mit dem Vorteil, daß keine stetige iiberdruckbildung eine Diffusion des teuren Wärmeträgermaterials bewirkt, wird erfindungsgemäß vorgeschlagen, ein Verfahren zu wihlen, das so aufgebaut ist, daß man die Flüssigkeit, die aus der Dachbahn abfließt, soweit in einem Fallrohr anreichern läßt, daß sie eine Füllung von etwa 2 m Wassersule bewirkt und dann über ein Gewicht- oder Steuerklappensystem plötzlich diese 2 m Wassersäule durchrutschen läßt, so daß zuerst durch den aufgestauten Druck im Fallrohr in etwa nur ein Druck aufgebaut werden muß, der dem Durchflußwiderstand der Flussigkeit durch die Dachhaut entspricht. Hierbei werden die Kanäle zwischen der unteren und oberen Deckhaut der Absorberbahn gut durchspült, und beim Öffnen der Klappe entsteht ein Sog, so daß sich eine aufbauende Druckdiffusion durch die Begrenzungaschichten abbaut, und infolgedessen auch Luftpolsterbildungen aufgrund des -I)ruck-Saug-Wechselspiels vermieden werden.To take advantage of pressurization - to prevent voids - to combine, but with the advantage that there is no constant overpressure formation Causes diffusion of the expensive heat transfer material is proposed according to the invention, to choose a procedure which is structured in such a way that one can remove the liquid from the roofing membrane drains, so far can enrich in a downpipe that it has a filling caused by about 2 m water column and then via a weight or control flap system suddenly this 2 m column of water can slip through, so that first through the pent up Pressure in the downpipe only needs to be built up to a pressure that corresponds to the flow resistance corresponds to the liquid through the roof membrane. Here are the channels between the lower and upper cover skin of the absorber membrane is thoroughly rinsed and when it is opened the flap creates a suction, so that a building pressure diffusion through the Boundary layers degrade and, as a result, air cushions as well of -I) jerk-suction interplay can be avoided.

Eine Vorrichtung zur Durchführung des Verfahrens ist entsprechend der beiliegenden Skizze dargestellt: mit (1) die Dachhaut, mit (2) der Flüssigkeitsbehälter, mit (3) der EntlüStungsstutzen, mit (4) die Flüssigkeitspumpe, die die Absorberflüssigkeit über die Druckleitung (5) der Dachbahn (1) zuführt, mit (6) eine Faileitung, mit (7) die Klappensteuerung, die entweder über Pendelgewicht z.B. bei 2 m Wasser'säule die Klappe öffnet, um sie dann bei Erreichen z.B. von Druck Null wieder zu schließen.A device for carrying out the method is corresponding shown in the enclosed sketch: with (1) the roof skin, with (2) the liquid container, with (3) the bleeding nozzle, with (4) the liquid pump that carries the absorber liquid via the pressure line (5) of the roofing membrane (1), with (6) a fail line, with (7) the flap control, which is either via pendulum weight, e.g. with a 2 m water column the flap opens in order to close it again when e.g. pressure zero is reached.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellte und beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderunpen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Absorber-Dachhaut so zu gestalten, daß die Flüssigkeit wechselwirkend im leichten Überdruck von bis zu ca. 2 m geringfügbig über dem notwendigen sich aufbauenden Fließdruck im Kollektor-Dachbahnen-System sich aufstaut, und dann durch Saugwirkung, die durch t;ffnen einer Klappe in der abfließenden Leitung der Dachhaut-Systemtechnik entsteht, ein Sog erzeugt wird, der das Nattensystem somit in einem Wechselspiel zwischen leichten Überdruck und leichte Sog aufzwingt. S5tr7tmrmrruch: - Leerseite -Of course, the invention is not limited to the embodiment shown and described in detail above, but numerous modifications are possible without, however, deviating from the basic idea of designing an absorber roof cladding in such a way that the liquid interacts with a slight excess pressure of up to approx. 2 m slightly above the necessary flow pressure that builds up in the collector roof membrane system, and then suction is generated by the suction effect that is created by opening a flap in the draining pipe of the roof membrane system technology, which thus in the vat system imposes an interplay between slight overpressure and slight suction.
