Abstract

The arrangement optimises the light ray spectrum and obtains a higher temperature stability affecting the capillary structure in the direction of the longitudinal axis by a constant temperature bonding agent. The heat is simultaneously transferred via the function of an absorber onto the heat accumulator medium. The whole arrangement is applied to the outer wall of a concrete house.The amount of light falling on the accumulator is regulated by a shading arrangement (roll blind, folding door, electrochromatic film etc.). The shading device is provided within the ventilation space and is controlled by a temperature sensor. A security glass pane protects the arrangement from the wether conditions and dirt.

Description

Es ist bekannt, Kapillarstrukturen vor Gebäudeaußenwänden anzubringen (BINE-Info-Service Nr. 4/91, ISSN 0937-8367, Informationsmaterial Fa. Okalux Kapillarglas GmbH, 97828 Marktheidenfeld, Handelsname "Kapilux"). Hierbei wird die Kapillarstruktur nicht direkt auf der Wandoberfläche angebracht, vielmehr ist ein Luftspalt vorhanden. Deshalb muß, um Luftzirkulation und damit Wärmeabfuhr an der Wandoberfläche nach außen dadurch unterbunden werden, indem an der rückwärtigen Seite der Kapillare eine weitere Glasscheibe oder Folie angebracht wird.
Problem: Es ist also eine zweite Glasscheibe oder Folie nötig. Dies erfordert eine aufwendigere Tragkonstruktion. Des weiteren tritt an der zweiten Scheibe zusätzlich unerwünschte Reflexion auf. Da die Kapillarstruktur nur bedingt selbsttragend ist, sind waagrechte Aussteifungen, z. B. durch Aluprofile notwendig. Insgesamt ist die Tragkonstruktion vom Materialbedarf und vom Fertigungsprozeß her aufwendig.It is known to apply capillary structures in front of the outer walls of the building (BINE-Info-Service No. 4/91, ISSN 0937-8367, information material from Okalux Kapillarglas GmbH, 97828 Marktheidenfeld, trade name "Kapilux"). Here, the capillary structure is not attached directly to the wall surface, rather an air gap is present. Therefore, in order to prevent air circulation and thus heat dissipation on the wall surface to the outside, another glass pane or film is attached to the rear side of the capillary.
Problem: So a second glass or foil is necessary. This requires a more complex support structure. In addition, undesired reflection also occurs on the second pane. Since the capillary structure is only self-supporting to a limited extent, horizontal stiffeners, e.g. B. necessary through aluminum profiles. Overall, the support structure is complex in terms of material requirements and the manufacturing process.

Es ist außerdem bekannt, Kapillarstrukturen direkt mittels eines temperaturbeständigen Klebers (gleichzeitig Absorber) direkt an der Gebäudewand zu befestigen und die noch offene Seite der Kapillarstruktur mittels eines Putzes, der kleine Glaskügelchen enthält, zu verputzen (Informationsmaterial Fa. Sto AG, 79778 Stühlingen, "transparentes Wärmedämm-Verbundsystem").
Problem: Der o. g. Systemaufbau verfügt über eine relativ schlechte Transmission des Lichtes aufgrund des Glasputzes. Wegen der rauhen Oberfläche ist im Langzeitbetrieb mit einer weiteren Verschlechterung der Transmission durch Verschmutzung zu rechnen. Aufgrund dessen, daß die Kapillarstruktur das Tragwerk für den Putz darstellt, sowie die während des Aufbringens des Putzes erhöhte dynamische Belastung, muß anstelle des preiswerteren PMMA auf das robustere Polycarbonat (PC) zurückgegriffen werden. Zwar kann aufgrund der schlechteren Transmission auf eine Abschattung verzichtet werden, dies führt jedoch dazu, daß im Hochsommer aufgrund der starken Strahlung eine maximale Energiezufuhr in den Wärmespeicher erfolgt. Dies trägt dann zur weiteren Erhöhung der Innenraumtemperaturen bei, dies ist zu diesem Zeitpunkt nicht erwünscht.
Lösung: Diese Probleme können durch eine Anordnung, wie sie im Patentanspruch aufgezeigt wird, gelöst werden.
Vorteil: Durch das direkte Aufkleben der Kapillarstruktur entfällt eine Tragkonstruktion hierfür als auch die zweite Glasscheibe. It is also known to attach capillary structures directly to the building wall using a temperature-resistant adhesive (simultaneously absorber) and to plaster the still open side of the capillary structure using a plaster containing small glass beads (information material from Sto AG, 79778 Stühlingen, " transparent thermal insulation composite system ").
Problem: The above system structure has a relatively poor transmission of light due to the glass plaster. Due to the rough surface, further deterioration in transmission due to contamination can be expected in long-term operation. Due to the fact that the capillary structure is the supporting structure for the plaster and the increased dynamic load during the application of the plaster, the more robust polycarbonate (PC) has to be used instead of the cheaper PMMA. Shading can be dispensed with due to the poorer transmission, but this means that in high summer there is a maximum energy input into the heat store due to the strong radiation. This then contributes to a further increase in interior temperatures, which is not desirable at this point in time.
Solution: These problems can be solved by an arrangement as shown in the claim.
Advantage: Directly gluing on the capillary structure eliminates the need for a supporting structure and the second glass pane.

Da die Scheibe selbsttragend ist, steht fast die gesamte Frontfläche zur Lichteinstrahlung zur Verfügung (praktisch keine Abschattung durch Tragkonstruktionen). Das Licht muß nur eine Scheibe durchdringen, dies führt zu einem besseren Gesamttransmissionsgrad. Des weiteren ist die Scheibe robuster und leichter zu reinigen als der Glasputz. Aufgrund der Abschattungseinrichtung kann die Energiezufuhr reguliert werden.Since the pane is self-supporting, almost the entire one stands Front surface available for light irradiation (practical no shading due to supporting structures). The light only has to penetrate a pane, this leads to a better overall transmittance. Furthermore, the pane is more robust and easier to clean than the glass plaster. Due to the shading device, the energy supply be regulated.

Aufgrund der Temperaturüberwachung (Sensor im Absorber eingelegt) kann die maximal zulässige Betriebstemperatur näher an die Temperaturstandfestigkeit des Kapillarmaterials gelegt werden. Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 ausgeführt. Durch leichtes Schrägschneiden der Kapillarstruktur kann diese vor Ort in einem für den Lichteinfall günstigen Winkel angebracht werden, wodurch auch für leicht west- oder ostorientierte Gebäudefassaden ein besserer Wirkungsgrad erzielt werden kann. Due to the temperature monitoring (sensor in the absorber inserted) may be closer to the maximum permissible operating temperature to the temperature stability of the capillary material will. An advantageous embodiment of the invention is in Claim 2 executed. By slight bevel cutting The capillary structure can be used on site for the Incident light can be attached at favorable angles, which also for slightly west or east-facing building facades better efficiency can be achieved.  

Beschreibung des Ausführungsbeispiels in der ZeichnungDescription of the embodiment in the drawing

Zunächst werden die für die Glashalterung notwendigen Befestigungspunkte geschaffen (z. B. durch Einschlaganker). Auf den Wärmespeicher (4), in allgemeinen die Gebäudeaußenwand, aus einem Material mit einer großen Wärmekapazität (z. B. Beton), wird der Kleber (3) mittels Zahnspachtel oder -traufel aufgetragen. Der Kleber dient gleichzeitig als Absorber, er ist deshalb vorzugsweise mattschwarz. In den Absorber (3) werden an geeigneten Stellen Temperatursensoren eingelegt, die der Temperaturregelung die Absorbertemperatur liefert. In den noch flüssigen Kleber wird die in Platten von handlicher Größe angelieferte Kapillarstruktur (1) mit der flachen Hand hineingedrückt. Das Luftpolster in den Kapillaren stellt gleichzeitig eine gute Wärmedämmung dar.First, the fastening points necessary for the glass bracket are created (e.g. using drop-in anchors). The adhesive ( 3 ) is applied to the heat accumulator ( 4 ), generally the outer wall of the building, from a material with a large heat capacity (e.g. concrete) using a notched trowel or trowel. The adhesive also serves as an absorber, so it is preferably matt black. Temperature sensors are placed in the absorber ( 3 ) at suitable points, which provide the temperature control with the absorber temperature. The capillary structure ( 1 ), which is supplied in plates of a handy size, is pressed into the still liquid adhesive with the palm of your hand. The air cushion in the capillaries also provides good thermal insulation.

An die Kapillarstruktur grenzen im Handbereich die Perimeterdämmung (9) und eine Polystyroldämmung (7), so daß die Kältebrücken minimiert werden. Des weiteren befindet sich ein Abschluß (10) unter der Scheibe (2), als Schutz vor großen Insekten. Bei geeigneter Konstruktion kann er auch die Last der Scheibe aufnehmen und somit die unteren Einschlaganker entbehrlich machen. Nun werden die Klemmglashalterungen (5), wie sie bereits im Geländerbau üblich sind, mittels Gewindestab in die Einschlaganker gedreht; auf die oberen Gewindestäbe werden die Rollolager aufgesetzt und schließlich das Rollo inklusive handelsüblichem Rohrmotor (6) mit integrierter Endabschaltung eingebaut.The perimeter insulation ( 9 ) and polystyrene insulation ( 7 ) border the capillary structure in the hand area, so that the cold bridges are minimized. Furthermore, there is a closure ( 10 ) under the pane ( 2 ) as protection against large insects. With a suitable construction, it can also take up the load of the pane and thus make the lower drop-in anchors unnecessary. Now the clamp glass holders ( 5 ), as are already common in railing construction, are turned into the impact anchors using a threaded rod; The roller blind bearings are placed on the upper threaded rods and finally the roller blind including the standard tubular motor ( 6 ) with integrated limit switch is installed.

In die Glashalterungen (5) werden die Scheiben (2) (Einscheibensicherheitsglas), aus Handlingsgründen auf jeweils 1 m Scheibenbreite begrenzt, eingesetzt. Auf die Scheibe (2) wird ein Abschlußdeckel (8) aufgesteckt, der individuell lackiert aus Blech oder GFK sein kann. An den Abschlußseiten der Anordnung sind geeignete Abschlußteile (Bleche) anzubringen, um das Eindringen von Schlagregen, Schmutz und Tieren zu verhindern. Aufgrund der thermodynamischen Verhältnisse kann an der Scheibe Kondenswasser auftreten. Deshalb ist für eine ausreichende Ventilation zu sorgen. Dies kann durch kleine Lüftungsspalten an den Scheibenrändern, insbesondere zwischen Scheibe (2) und dem oberen Abschlußdeckel (8) erreicht werden.The panes ( 2 ) (single-pane safety glass) are inserted into the glass holders ( 5 ), limited to 1 m pane width for handling reasons. A cover plate ( 8 ) is placed on the disc ( 2 ), which can be individually painted from sheet metal or GRP. Suitable end pieces (sheets) must be attached to the end sides of the arrangement to prevent the ingress of driving rain, dirt and animals. Due to the thermodynamic conditions, condensation can occur on the window. Adequate ventilation must therefore be ensured. This can be achieved by small ventilation gaps on the edges of the pane, in particular between the pane ( 2 ) and the upper cover plate ( 8 ).
