Abstract
Description
Die Erfindung betrifft die Ausführung einer mehrschaligen Fassade mit einem transparenten Absorber.The Invention relates to the embodiment a multi-layered facade with a transparent absorber.
Stand der TechnikState of the art
Seit Jahrhunderten sind mehrschalige Wandaufbauten, z. B. in Form von Verkleidungen mit Schiefer oder Holz, bekannt. Dabei war neben der Funktion des Schutzes vor Schlagregen auch die Hinterlüftung zur Abtragung von Solarwärme das Ziel. Schon im 19. Jahrhundert wurden sogenannte „Kollektor-Fassaden” entwickelt und teilweise auch getestet.since Centuries are multi-shell wall structures, z. B. in the form of Cladding with slate or wood, known. It was next to the function the protection against driving rain also the rear ventilation for the removal of solar heat the goal. As early as the 19th century, so-called "collector facades" were developed and partially tested.
Mit Aufkommen der Skelettbauweise boten transparente Ganzglasvorhangfassaden die Möglichkeit das Konzept des „fließenden Raumes” zu verwirklichen. Klimatechnisch traten dabei allerdings Probleme, wie z. B. höherer Heiz- und Kühlbedarf durch hohe Wärmedurchgangskoeffizienten und hohe Transmissionskoeffizienten, auf. Seit den 1970er Jahren wurden Abluftfassaden entwickelt, welche über einen durchströmten Luftspalt innerhalb zweier Gebäudehüllen zumindest ein behaglicheres Raumklima durch Temperierung der Glasscheiben schufen. Mit der Entwicklung von Wärmeschutzgläsern sind diese Wandtemperierungen weitgehend hinfällig geworden.With The emergence of the skeleton construction offered transparent all-glass curtain facades the possibility to realize the concept of "flowing space". However, air conditioning problems occurred, such. Higher heating and cooling demand through high heat transfer coefficients and high transmission coefficients, on. Since the 1970s Exhaust facades were developed, which have a flow-through air gap within two building envelopes at least created a comfortable indoor climate by tempering the glass panes. With the development of heat protection glasses are These wall tempering has become largely obsolete.
Durch den Einsatz von Jalousien auch in Verbindung mit Sonnenschutzgläsern konnten die Kühllasten gesenkt werden. Als Weiterentwicklung der Jalousie mit ausschließlicher Verschattungsfunktion können Lichtleitsysteme angesehen werden. Eine andere Richtung der Entwicklung stellt die Nutzung der Jalousien als Absorber für Solarstrahlung dar.By the use of blinds also in conjunction with sun protection lenses could the cooling loads be lowered. As a further development of the blind with exclusive Shading function can Be viewed. Another direction of development represents the use of the blinds as an absorber for solar radiation.
Problemstellungproblem
Als Solarabsorber zur Gewinnung thermischer Energie werden innerhalb mehrschaliger Fassaden hauptsächlich massive Wandelemente und Jalousien genutzt. Um dem Konzept des „fließenden Raumes” gerecht zu werden, ist diesbezüglich lediglich der Einsatz von Jalousien möglich.When Solar absorbers for the production of thermal energy are within multi-layered facades mainly massive wall elements and blinds used. To live up to the concept of "flowing space" to become is in this regard only the use of blinds possible.
Die Nutzung von Jalousien als Solarabsorber in einer transparenten Fassade birgt allerdings einige Nachteile. Durch die opake Ausführung der Lamellen entsteht bei einer geschlossenen Jalousie eine undurchsichtige Wand. Wenn die Jalousie nur bereichsweise, z. B. als vertikale Streifen, geschlossen wird, entstehen zum einen Beeinträchtigungen durch Kontrastbildung und zum anderen Einschränkungen der freien Sicht. Bedingt durch die relativ komplexe Konstruktion der Jalousien ist diese Bauart kostenintensiv und mit relativ hohen Betriebs- bzw. Wartungskosten verbunden.The Use of blinds as solar absorbers in a transparent facade However, there are some disadvantages. Due to the opaque execution of the Slats create an opaque with a closed blind Wall. If the blind only partially, z. As vertical stripes, closed, caused on the one hand impairments caused by contrast and on the other hand restrictions the free view. Due to the relatively complex construction Venetian blinds, this type is costly and relatively high Operating and maintenance costs associated.
Bei einer Jalousie mit angestellten Lamellen sind die gleichen Beeinträchtigungen vorhanden.at Blinds with slats are the same drawbacks available.
Die Ausführung der inneren Gebäudehülle als Sonnenschutzverglasung bietet die Möglichkeit einer freien Sicht mit gleichzeitiger Erzeugung von Wärme. Allerdings entstehen bei diesem System in den absorbierenden Bauteilen hohe Temperaturschwankungen und folglich auch mechanische Belastungen. Zusätzlich besteht die Gefahr, dass sich durch hohe Glastemperaturen zeitweise die solaren Gewinne verringern und als Kühllast wirksam werden.The execution the inner building envelope as Sun protection glazing offers the possibility of a clear view with simultaneous generation of heat. However arise at This system in the absorbent components high temperature fluctuations and consequently also mechanical loads. In addition, there is a risk because of high glass temperatures at times the solar gains reduce and as a cooling load be effective.
Beschreibung der ErfindungDescription of the invention
Gegenstand
der Erfindung ist die Platzierung eines Absorbers aus einem transparenten
Material innerhalb eines Luftspaltes zwischen zwei Schalen einer
Fassade.
Sein Absorptionsgrad im Spektrum der Solarstrahlung ist größer als 0,05. Die Transmissions-, Reflexions- und Absorptionsgrade können sich innerhalb der Absorberebene verändern. Eine Erhöhung des Absorptionsgrades sollte sinnvollerweise vorerst in den Bereichen der nichtsichtbaren Strahlung mit entsprechend hoher Selektivität erfolgen. Weitere Erhöhungen des Absorptionsgrades erfolgen auf Kosten der Selektivität und können eine Verdunklung oder auch eine Verfärbung des transparenten Absorbers bedeuten.Be Absorption level in the spectrum of solar radiation is greater than 0.05. The transmission, reflection and absorption levels can be change within the absorber level. An increase in the Absorptionsgrades should usefully for the time being in the areas the non-visible radiation with a correspondingly high selectivity. Further increases The degree of absorption take place at the expense of selectivity and can Darkening or even a discoloration of the transparent absorber mean.
Der Absorber kann aus mehreren Schichten oder auch aus mehreren Segmenten verschiedener Materialien bestehen.Of the Absorber can consist of several layers or even of several segments consist of different materials.
Zusätzlich können Lichtleitsysteme
verwendet werden, welche zur Reflexion von Direktstrahlung in den
anschließenden
Raum dienen. In
