Abstract
Description
Die Erfindung betrifft einen Deckenluftauslass mit einem Außenrohr, einem hierin konzentrisch angeordneten Kernrohr, Drallschaufeln zwischen dem Kernrohr und dem Außenrohr, mittels derer ein Drallluftstrom derart führbar ist, dass er im Wesentlichen senkrecht zu einer Durchströmrichtung des Deckenluftauslasses aus einem kreisringförmigen Drallauslass austritt, und mit einem in dem Kernrohr angeordneten Sperrelement, mittels dessen ein durch das Kernrohr zu einem Kernauslass geführter Kernluftstrom sperrbar ist.The invention relates to a Deckenluftauslass with an outer tube, one concentric therein arranged core tube, swirl blades between the core tube and the outer tube, by means of which a swirling air flow can be guided such that it is substantially perpendicular to one Flow direction of the Deckenluftauslasses exits from an annular twist outlet, and with a arranged in the core tube blocking element, by means of which a through the Core tube to a core outlet guided core air flow can be blocked.
Solche Deckenluftauslässe ermöglichen - um den heutigen Komfortansprüchen gerecht zu werden und eine energetisch effektive Klimatisierung des Raumes zu erzielen - die Änderung der Ausströmrichtung der Zuluft abhängig von deren Über- bzw. Untertemperatur gegenüber der Raumluft. Zur Vermeidung von Zugerscheinungen wird gekühlte Zuluft horizontal, geheizte Zuluft zur schnellen Aufheizung jedoch vertikal nach unten ausgeblasen.Such ceiling air outlets allow - to meet today's comfort requirements and to achieve an energetically effective air conditioning of the room - the change the outflow direction of the supply air depending on their over- or under-temperature compared the room air. To avoid drafts cooled supply air is horizontal, heated Supply air for quick heating but blown down vertically.
Gegenüber den allgemein bekannten Drallluftauslässen, wie sie beispielsweise in der DE 36 22 146 offenbart sind, weisen solche Deckenluftauslässe ein zusätzliches, konzentrisch in dem Außenrohr angeordnetes Kernrohr auf. Der Zuluftstrom wird so in dem Deckenluftauslass einerseits in einen Drallluftstrom - der zwischen Außenrohr und Kernrohr in bekannter Weise über Drallschaufeln geführt und im Wesentlichen radial (senkrecht zur Durchströmrichtung des Deckenluftauslasses) ausgeblasen wird - und einen aus dem Kernrohr axial (in Durchströmrichtung) ausgeblasenen Kernluftstrom aufgeteilt. Die Ausblasrichtung des wieder zusammen geführten Zuluftstroms wird durch Regelung der Drall- und Kernluftströme abgestimmt.Compared to the well-known swirl air outlets, as described for example in DE 36 22,146, such ceiling air outlets have an additional, concentric in the Outer tube arranged core tube. The supply air flow is thus in the ceiling air outlet on the one hand in a swirl air flow - between the outer tube and core tube in a known manner guided over swirl vanes and substantially radially (perpendicular to the flow direction the Deckenluftauslasses) is blown out - and one from the core tube axially (in the flow direction) blown out core air flow. The blowout of the back together guided supply air flow is tuned by controlling the swirl and core air flows.
Bei gesperrtem Kernrohr strömt die Zuluft vollständig über die Drallschaufeln, der Deckenluftauslass wirkt wie ein klassischer Drallluftauslass. Mit zunehmender Öffnung des Kernrohres steigt der Kernluftstrom und induziert auch der aus dem Drallauslass ausströmenden Zuluft eine axiale Komponente. Bei vollständig geöffnetem Kernrohr strömt die Zuluft zum größeren Teil durch den Kernauslass. Die Drallschaufeln wirken im Drallluftstrom zusätzlich als Drosseln, so dass die Zuluft im Wesentlichen in Durchströmrichtung des Deckenluftauslasses ausströmt. When the core tube is locked, the supply air flows completely through the swirl vanes, the ceiling air outlet acts like a classic swirl air outlet. With increasing opening of the core tube the core air flow increases and also induces the incoming air flowing out of the swirl outlet an axial component. When the core tube is completely open, the supply air flows to the larger one Part through the core outlet. The swirl vanes also act as swirling air flow Chokes, so that the supply air substantially in the direction of flow of the ceiling air outlet flows.
Beispielsweise in der DE 80 03 910 U1 ist ein solcher Deckenluftauslass offenbart, der oberhalb des Kernrohres einen in der Durchströmrichtung verschiebbaren Ventilteller aufweist. Abhängig von seiner Stellung versperrt der Ventilteller mehr oder weniger die Durchströmung des Kernrohres. Die DE 41 39 099 A1 offenbart einen Deckenluftauslass mit einem ähnlichen Prinzip, wobei hier ein in Durchströmrichtung verschiebbares Kernrohr je nach Stellung von einer feststehenden Prallplatte mehr oder weniger gesperrt wird.For example, in DE 80 03 910 U1 such a ceiling air outlet is disclosed above the core tube has a displaceable in the flow direction valve plate. Depending on its position, the valve disc blocks more or less the flow of the core tube. DE 41 39 099 A1 discloses a ceiling air outlet with a similar principle, in which case a displaceable in the flow direction core tube depending on Position is more or less locked by a fixed baffle plate.
Die Ausströmcharakteristik solcher Deckenluftauslässe kann - wie in der DE 196 51 480 A1 offenbart - mittels einer Verstelleinrichtung verstellt werden. Die dort vorgeschlagene selbsttätige Verstelleinrichtung kann allerdings - ohne Zufuhr von Sekundärenergie - nur vergleichsweise geringe Kräfte zur Verstellung eines Sperrelements aufbringen. Die Verstellung des Ventiltellers oder des Kernrohres aus den bekannten verstellbaren Deckenluftauslässen ist mit diesen beschränkten Kraftreserven nicht möglich.The Ausströmcharakteristik such ceiling air outlets can - as in DE 196 51 480 A1 disclosed - be adjusted by means of an adjustment. The proposed there automatic However, adjusting device can only - comparatively without supply of secondary energy apply small forces to adjust a locking element. The adjustment the valve plate or the core tube from the known adjustable Deckenluftauslässen is not possible with these limited power reserves.
Der Erfindung liegt die Aufgabe zugrunde, einen Deckenluftauslass vorzuschlagen, dessen Ausströmcharakteristik ohne Einsatz von Sekundärenergie mit minimalem Kraftaufwand verstellbar ist und der so den Einsatz einer selbsttätigen Stelleinrichtung ermöglicht. Um gegenüber den bekannten Deckenluftauslässen am Markt konkurrenzfähig zu sein, soll der Deckenluftauslass dabei einfach auszulegen, preiswert herzustellen und im Betrieb wartungsarm sein.The invention has for its object to propose a Deckenluftauslass whose Outflow characteristic without the use of secondary energy adjustable with minimal effort is and thus allows the use of an automatic adjusting device. Opposite To be competitive on the market for the well-known ceiling air outlets, the ceiling air outlet should be easy to design, inexpensive to manufacture and low maintenance during operation.
Ausgehend von den bekannten Deckenluftauslässen wird die Aufgabe nach der Erfindung dahingehend gelöst, dass das Sperrelement mindestens eine Klappe aufweist, die um eine senkrecht zu der Durchströmrichtung verlaufende Klappachse um einen Klappwinkel klappbar ist. Based on the known Deckenluftauslässen the object of the invention solved in that the blocking element has at least one flap, which is around a perpendicular to the flow direction extending folding axis hinged to a folding angle is.
Durch geeignete Anordnung einer solchen Klappe auf der Klappachse nach allgemein bekannten Verfahren kann der fluiddynamische Druck auf die Teilflächen zu beiden Seiten der Klappachse abhängig vom jeweiligen Auslegungsfall nahezu zum Ausgleich gebracht und so der strömungsbedingte Widerstand gegen eine Verstellung der Klappe minimiert werden. Durch eine hochwertige Lagerung der Klappachse kann darüber hinaus auch der Reibungswiderstand, der einer Verstellung der Klappe entgegen steht, minimiert werden. Außerdem stellen Klappen als Sperrelement im Vergleich zur Verwendung von verschiebbaren Ventiltellem oder verschiebbaren Kernrohren eine erhebliche konstruktive Vereinfachung dar, die sich unmittelbar auch im Herstellungs- und Wartungsaufwand sowie in den Herstellungskosten des erfindungsgemäßen Deckenluftauslasses niederschlägt.By suitable arrangement of such a flap on the folding axis according to general known methods, the fluid dynamic pressure on the faces to both sides the folding axis depending on the respective design case almost balanced and so the flow-related resistance to an adjustment of the flap can be minimized. By a high-quality storage of the folding axis can also beyond the frictional resistance, which opposes an adjustment of the flap can be minimized. Also put Flaps as a blocking element compared to the use of sliding valve heads or displaceable core tubes represents a significant structural simplification, which directly in the production and maintenance costs as well as in the production costs the Deckenluftauslasses invention precipitates.
Das Sperrelement eines erfindungsgemäßen Deckenluftauslasses kann insbesondere genau eine Klappe aufweisen. So kann die Anzahl der für die Verstellung des Sperrelements erforderlichen mechanischen Bauelemente - Hebel, Schub- und Zugstangen - auf ein Minimum reduziert werden, wodurch wiederum die Konstruktion vereinfacht wird.The blocking element of a Deckenluftauslasses invention can in particular exactly have a flap. Thus, the number of required for the adjustment of the blocking element mechanical components - levers, push rods and tie rods - to a minimum be reduced, which in turn simplifies the construction.
Alternativ kann das Sperrelement eines erfindungsgemäßen Deckenluftauslasses auch eine Mehrzahl von Klappen mit in einer zu der Durchströmrichtung senkrechten Ebene parallel verlaufenden Klappachsen aufweisen. So wird die strömungstechnisch bedingte Last auf jeder einzelnen Klappe verringert, so dass hier einfachere, insbesondere leichtere und preiswertere Materialien und weniger hochwertige Lagerelemente zum Einsatz kommen können. Außerdem ist die strömungsdynamische Auslegung schmalerer Klappen weniger aufwändig, weil Auftriebs- und Sogeffekte hier weniger in Betracht gezogen werden müssen.Alternatively, the blocking element of a Deckenluftauslasses invention also a Plurality of flaps with a plane perpendicular to the direction of flow parallel have running folding axes. This is how the aerodynamic load on each reduced single flap, so here easier, especially lighter and cheaper Materials and less high-quality bearing elements can be used. Furthermore is the fluid dynamic design narrower flaps less expensive, because Buoyancy and suction effects need less to be considered here.
Besonders bevorzugt sind an einem solchen Deckenluftauslass neben einander angeordnete Klappen in entgegengesetztem Drehsinn klappbar. Beim Öffnen des Sperrelements entsteht dann zwischen jedem Klappenpaar strömungstechnisch eine parallel zur Durchströmrichtung des Deckenluftauslasses gerichtete Düse, die den Kernluftstrom parallel zur Durchströmrichtung des Deckenluftauslasses ausrichtet und mit zunehmender Anzahl der parallel angeordneten Klappen zugleich vergleichmäßigt. Particular preference is given to such a ceiling air outlet next to each other Flaps folding in opposite direction of rotation. When opening the locking element arises then between each pair of flaps fluidly one parallel to the flow direction the Deckenluftauslasses directed nozzle, the core air flow parallel to the flow direction the Deckenluftauslasses aligned and arranged with increasing number of parallel Flaps at the same time evened.
Vorteilhafter Weise weist ein erfindungsgemäßer Deckenluftauslass ein Gleichrichterelement auf, das in dem Kernrohr in Durchströmrichtung hinter dem Sperrelement angeordnet ist und mittels dessen der Kernluftstrom in Richtung der Durchströmrichtung ausrichtbar ist. Gleichrichterelemente sind in vielfältiger Ausführung allgemein bekannt und beispielsweise in der oben zitierten DE 36 22 146 A1 beschrieben. In Kombination mit einem erfindungsgemäßen Deckenluftauslass kann prinzipiell ein Gleichrichterelement mit jedem beliebigen Kanalquerschnitt zum Einsatz kommen, solange die Kanäle in Durchströmrichtung des Deckenluftauslasses verlaufen und eine Wandung aufweisen, die parallel zur Klappachsenrichtung verläuft. Insbesondere können auch derart ausgerichtete Lamellen als Gleichrichterelement verwendet werden.Advantageously, a ceiling air outlet according to the invention has a rectifier element on, which is arranged in the core tube in the flow direction behind the blocking element and by means of which the core air flow can be aligned in the direction of the flow direction. Rectifier elements are well known in a variety of designs and, for example, in the cited above DE 36 22 146 A1. In combination with an inventive Ceiling air outlet can in principle be a rectifier element with any channel cross-section be used as long as the channels in the flow direction of the Deckenluftauslasses run and have a wall which is parallel to the folding axis direction. In particular, such aligned slats can be used as a rectifier element become.
Besonders bevorzugt ist ein solches Gleichrichterelement in dem Kernauslass angeordnet. Zum Einen werden Verwirbelungen des Kernluftstroms mit steigendem Abstand von dem Sperrelement zunehmend ausgeglichen, zum Andern wird der optische Eindruck des erfindungsgemäßen Deckenluftauslasses durch Verdecken des Kernrohrhohlraums verbessert.Such a rectifier element is particularly preferably arranged in the core outlet. On the one hand, turbulences of the core air flow with increasing distance from the Blocking increasingly balanced, the other is the visual impression of the invention Ceiling air outlet improved by covering the core tube cavity.
Ein erfindungsgemäßer Deckenluftauslass weist vorzugsweise eine Stelleinrichtung auf, mittels derer der Klappwinkel stellbar ist. Ein direkter Eingriff in den Deckenluftauslass ist dann zur Veränderung seiner Ausblascharakteristik nicht erforderlich. Insbesondere kann eine solche Stelleinrichtung ein nach Außen geführter manuell zu betätigender Hebel oder ein elektromotorischer, von einer zentralen Steuerungseinheit angesteuerter Antrieb sein.An inventive ceiling air outlet preferably has an adjusting device by means of of which the folding angle is adjustable. A direct intervention in the Deckenluftauslass is then Not required to change its Ausblascharakteristik. In particular, such Actuator means an externally guided manually operated lever or an electromotive, be controlled by a central control unit drive.
Besonders bevorzugt wird in einer solchen Stelleinrichtung jedoch der Klappwinkel selbsttätig abhängig von einer Temperaturdifferenz zwischen einem Raumluftfühler und einem Zuluftfühler gestellt. Eine derartige selbsttätige Stelleinrichtung, wie sie beispielsweise in der oben zitierten DE 196 51 480 A1 beschrieben ist, ermöglicht den autonomen ― von Sekundärenergie oder manuellem Eingriff unabhängigen - Betrieb des erfindungsgemäßen Deckenluftauslasses. Insbesondere werden durch den Einsatz derartiger erfindungsgemäße Deckenluftauslässe die Installations-, Betriebs- und Wartungskosten der lufttechnischen Anlage signifikant reduziert. However, the folding angle is particularly preferred in such a control device automatically depending on a temperature difference between a room air sensor and a supply air sensor posed. Such an automatic adjusting device, as shown for example in the DE 196 51 480 A1 cited above enables the autonomous - of secondary energy or manual intervention independent - operation of the Deckenluftauslasses invention. In particular, the use of such inventive ceiling air outlets the installation, operating and maintenance costs of the ventilation system are significant reduced.
Während die zuvor bekannten Konstruktionen von Deckenluftauslässen mit vertikal verstellbaren Ringen, Blenden oder winkelverstellbaren Drallschaufeln in der Herstellung kostenintensiv und in der Anwendung insbesondere im Industriebereich aufgrund der vielen und teilweise großen Verstellelemente für Verschmutzungen und Beschädigungen anfällig sind, bieten die erfindungsgemäßen Deckenluftauslässe einen sehr einfachen, aber hocheffizienten Verstellmechanismus.While the previously known constructions of ceiling air outlets with vertically adjustable Rings, diaphragms or angle-adjustable swirl vanes in production costly and in the application especially in the industrial sector due to the many and partly large adjusting elements are prone to contamination and damage The ceiling air outlets according to the invention a very simple, but highly efficient Adjustment mechanism.
