Es ist Aufgabe der Erfindung, ein Dach zur Erzeugung von warmen Wasser durch Sonneneinstrahlung zu schaffen, das billig ist und bei dem insbesondere Warmwassererzeugung ohne zusätzliche Absorber und/oder Kollektoren wirksam möglich ist.It is an object of the invention to provide a roof for the generation of warm To create water from sunlight that is cheap and in which in particular hot water generation without additional absorbers and / or collectors is effectively possible.
Außerdem soll der gesamte Bereich einer Dachseite, die vorzugsweise nach Süden gerichtet ist, großflächig hohe Temperaturen erzeugen, die unter der Dachinnenfläche wirksam werden und dort auf den Wärmeträger einwirken.In addition, the entire area of a roof side should preferably facing south, high temperatures over large areas generate that take effect under the roof surface and there act on the heat transfer medium.
Gemäß der Erfindung erfolgt dieses durch einen Wasserkreislauf, der durch ein Rohr gebildet wird. Dieses ist in gleichen Abständen und gleich langen Schlaufen jeweils rechtwinklig so umgebogen, daß es auf allen vorhandenen und die Dachhaut tragenden Latten und auf den Sparren, auf denen die Latten in bekannter Weise befestigt sind, aufliegt. Auf den zwischen den Sparren befindlichen Wärmedämmplatten sind breite U-förmige Wärmespeicher befestigt, die die Wärmedämmplatten völlig überdecken.According to the invention, this is done by a water cycle, which is formed by a tube. This is at equal intervals and loops of the same length are bent at right angles, that it is on all existing and supporting the roof skin Battens and on the rafters on which the battens are known in Are attached, rests. On the one between the rafters Thermal insulation boards are wide U-shaped heat stores attached, which completely cover the thermal insulation panels.
Die Höhe der Sparren ist so bemessen, daß jeder auf den Dämmplatten aufgebrachte U-förmige Wärmespeicher einen über die Dachhöhe verlaufenden Warmlaufkanal bildet. Dieser wird von der Dachhaut abgedeckt.The height of the rafters is such that everyone is on the insulation boards applied U-shaped heat storage one over the roof height running warming duct forms. This is from the roof skin covered.
Der U-förmige Wärmespeicher besteht aus schwarz eloxierter Aluminiumfolie oder aus dünnem Schwarzblech.The U-shaped heat accumulator consists of black anodized aluminum foil or from thin black plate.
Die Dachhaut besteht aus Dachdeckungselementen, die aus dünnem Stahlblech im Ziehverfahren hergestellt sind.The roof skin consists of roofing elements made of thin Sheet steel are produced in the drawing process.
In der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt und wird im folgenden näher beschrieben. Es zeigtIn the drawing is an embodiment according to the invention shown and is described in more detail below. It shows
Fig. 1 die Draufsicht auf ein Dach, Fig. 1 is a plan view of a roof,
Fig. 2 einen Schnitt nach der Linie A-A der Fig. 1 und Fig. 2 shows a section along the line AA of Fig. 1 and
Fig. 3 einen Schnitt nach der Linie B-B der Fig. 1. Fig. 3 is a section along the line BB in FIG. 1.
Nach Fig. 1 besteht das Dach aus den üblichen Sparren 4, auf denen die Latten 3, welche die Lattung für die Dachhaut 2 bilden, befestigt sind.According to Fig. 1, the roof from the usual rafters 4 on which the slats 3, which form the battens for the roof 2, are mounted.
Ein Rohr 1, welches fast als endlos zu bezeichnen ist, geht von einem Wärmetauscher 8 und einer zwischengeschalteten Pumpe 9 zum Dach und bildet unter der Dachhaut 2 liegend einen Wasserkreislauf. Dieser wird durch das in gleichen Abständen und gleichen Längen zu Schlaufen 1, die jeweils durch das rechtwinklig umgebogene Rohr entstehen, gebildet. Die Schlaufen sind der Wärmeträger für das durchlaufende Wasser.A pipe 1 , which is almost endless, goes from a heat exchanger 8 and an intermediate pump 9 to the roof and forms a water circuit lying under the roof skin 2 . This is formed by the loops 1 , which are formed by the tube bent at right angles, at equal intervals and equal lengths. The loops are the heat transfer medium for the water flowing through.
Demnach sind die Schlaufen 1 so gestaltet, daß sie auf allen vorhandenen und die Dachhaut 2 tragenden Latten 3 und auf den Sparren 4 aufliegen.Accordingly, the loops 1 are designed so that they rest on all existing slats 3 and the roof skin 2 and on the rafters 4 .
Zwischen den Sparren 4 sind Wärmedämmplatten 5 eingesetzt, die im wesentlichen auf Schienen 10, die an den Sparren befestigt sind, aufliegen. Auf den Wärmedämmplatten wiederum sind breite, U-förmige Wärmespeicher 6 befestigt, welche die Wärmedämmplatten völlig überdecken.Between the rafters 4 thermal insulation panels 5 are used, which lie essentially on rails 10 which are attached to the rafters. In turn, wide, U-shaped heat accumulators 6 are attached to the thermal insulation panels, which completely cover the thermal insulation panels.

Die Wärmespeicher bestehen vorzugsweise aus schwarz eloxierter Aluminiumfolie, können aber auch aus dünnem Schwarzblech hergestellt sein. Durch ihren breiten U-förmigen Querschnitt liegen sie auch an den Sparren an. Die Höhe derselben ist so bemessen, daß die Wärmespeicher 6 einen über die ganze Dachhöhe verlaufenden Wärmeluftkanal 7 bilden. Dieser liegt zwischen der Dachhaut 2 und jeweils einer Dämmplatte 5.The heat stores are preferably made of black anodized aluminum foil, but can also be made of thin black plate. Thanks to their wide U-shaped cross-section, they also rest on the rafters. The height of the same is dimensioned such that the heat accumulators 6 form a heat air duct 7 running over the entire roof height. This lies between the roof skin 2 and an insulation board 5 .
Die Dachhaut besteht aus Dachdeckungselementen, die aus dünnem Stahlblech im Ziehverfahren hergestellt sind und außen durch dunkele Farbgebung die Sonnenstrahlung stark akkumulieren und an ihren hellgefärbten Innenflächen die gespeicherte Wärme an die Warmluftkanäle 7 abgeben.The roof skin consists of roof covering elements, which are made of thin sheet steel using the pulling process and, due to their dark coloring, accumulate the sun's rays on the outside and give off the stored heat to the warm air ducts 7 on their light-colored inner surfaces.
In diesen entstehen bei entsprechender Sonneneinstrahlung Temperaturen bis 80°C, so daß die Rohrteile der Schlaufen 1′, durch welche über die Pumpe 9 nach Fig. 1 ein ständiger Wasserkreislauf in Gang gehalten wird, entsprechend erwärmt werden und damit auch das Wasser. Dieses durchläuft den Wärmetauscher 8 und erwärmt das Brauchwasser in demselben.In these arise with appropriate sunlight temperatures up to 80 ° C, so that the tubular parts of the loops 1 ' , through which a constant water cycle is kept in motion by means of the pump 9 according to FIG. 1, are heated accordingly and thus the water. This passes through the heat exchanger 8 and heats the process water in the same.
