Abstract

In the device, which has a flat, elongate, upright housing, an air supply connection of the housing and blow-out slots arranged on the upper side of the housing, the blow-out slots are arranged transversely to the longitudinal extension of the housing and have a mutual separation which is a multiple of their width.

Description

Die Erfindung betrifft ein Fensterschleiergerät zur Klimatisierung von Räumen gemäß dem Oberbegriff des An­spruchs 1.The invention relates to a window curtain for air conditioning rooms according to the preamble of claim 1.

Fensterschleiergeräte dieser Gattung werden unterhalb der Fenster an der Fensterbrüstung angeordnet und bla­sen die Zuluft nach Art eines Schleiers entlang der Fensterfläche nach oben. Der Zuluftschleier schirmt die im allgemeinen eine Kältebrücke bildende Fensterfläche ab. Die entlang der Fensterfläche nach oben in den Raum geblasene Zuluft strömt an der Raumdecke entlang und sinkt in den Raum ab, sobald die Strahlgeschwindigkeit abgebaut ist. Da die nach oben eingeblasenen Zuluft­strahlen durch Induktion Raumluft aus der Aufenthalts­zone mitnehmen, ergibt sich eine walzenartige Luftströ­mung in dem Raum, die zu einer guten und schnellen Durchlüftung des Raumes führt.Window curtains of this type are arranged below the windows on the window sill and blow the supply air upwards along the window surface in the manner of a veil. The supply air curtain shields the window area which generally forms a cold bridge. The supply air blown upwards into the room along the window surface flows along the ceiling and sinks into the room as soon as the jet speed is dismantled. Since the supply air jets that are blown in upwards take room air from the occupied zone by induction, a roller-like air flow results in the room, which leads to good and quick ventilation of the room.

Es sind Fensterschleiergeräte für Zweikanal-Anlagen be­kannt, denen kalte und warme Zuluft zugeführt wird, wo­bei das Mischungsverhältnis von Kaltluft und Warmluft dem jeweiligen Bedarf angepaßt werden kann. Weiter sind Fensterschleiergeräte für Einkanal-Anlagen bekannt, bei denen Raumluft durch Induktion in das Gehäuse angesaugt wird und zusammen mit der Zuluft ausgeblasen wird. Das Mischungsverhältnis von angesaugter Raumluft und Zuluft ist zur Anpassung an den Klimatisierungsbedarf verän­derlich. Alle diese Fensterschleiergeräte haben den Vorteil, daß bei allen Betriebsbedingungen die gleiche Gesamtluftmenge in den Raum geblasen wird und die Tem­peratur der eingeblasenen Luft den jeweiligen Bedingun­gen angepaßt wird. Der ausgeblasene Luftvolumenstrom und die Strahlgeschwindigkeit können für eine optimale Durchspülung des Raumes ausgelegt werden. Fenster­schleiergeräte dieser Art sind jedoch konstruktiv re­lativ aufwendig und beanspruchen relativ viel Platz.Window curtain devices for two-channel systems are known, to which cold and warm supply air is supplied, the mixing ratio of cold air and warm air being able to be adapted to the respective requirements. Furthermore, window curtain devices for single-channel systems are known in which room air is drawn into the housing by induction and is blown out together with the supply air. The mixing ratio of the sucked-in room air and supply air can be changed to adapt to the air conditioning requirement. All these window curtain devices have the advantage that the same total amount of air is blown into the room under all operating conditions and the temperature of the air blown in is adapted to the respective conditions. The blown air volume flow and the jet speed can be designed for an optimal flushing of the room. Window curtains of this type, however, are structurally relatively complex and take up a relatively large amount of space.

Weiter sind Fensterschleiergeräte für Einkanal-Anlagen bekannt, die nur Zuluft ausblasen und bei denen die An­passung an die jeweiligen Raumbedingungen durch Ände­rung des eingeblasenen Zuluftvolumenstroms erfolgt. Diese Fensterschleiergeräte sind konstruktiv besonders einfach. Die Änderung des eingeblasenen Zuluftvolumen­stroms führt jedoch zu einer Änderung der Strahlge­ schwindigkeit und damit der Raumdurchspülung.Furthermore, window curtain devices for single-channel systems are known which only blow out supply air and in which the adaptation to the respective room conditions takes place by changing the injected supply air volume flow. These window curtains are structurally particularly simple. However, the change in the incoming air volume flow leads to a change in the jet speed and thus the flushing of the room.

Der Erfindung liegt die Aufgabe zugrunde, ein Fenster­schleiergerät, bei welchem nur Zuluft ausgeblasen wird, so auszubilden, daß auch bei Änderungen des zugeführten Zuluftvolumens eine gute Durchmischung mit der Raumluft und eine stabile Durchspülung des Raumes erfolgt.The invention has for its object to provide a window curtain, in which only supply air is blown out, so that even with changes in the supply air volume, good mixing with the room air and a stable flushing of the room takes place.

Diese Aufgabe wird bei einem Fensterschleiergerät der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils des Anspruchs 1.This object is achieved according to the invention in a window curtain of the type mentioned at the outset by the features of the characterizing part of claim 1.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß sind die Ausblasschlitze des Fenster­schleiergerätes quer zur Längserstreckung des Gehäuses angeordnet. Dadurch kann bei einem ausreichenden Ge­samtdurchtrittsquerschnitt der Ausblasschlitze ein so großer Abstand zwischen den einzelnen Ausblasschlitzen eingehalten werden, daß die Raumluft zwischen die aus den Ausblasschlitzen austretenden Zuluftstrahlen ein­dringen und durch Induktion von den Zuluftstrahlen mit­genommen werden kann. Es bilden sich somit zwischen den Luftstrahlen der einzelnen Ausblasschlitze Induktions­zonen aus, die eine hohe Induktion und eine schnelle Vermischung von Zuluft und Raumluft bewirken.According to the invention, the blowout slots of the window curtain are arranged transversely to the longitudinal extent of the housing. As a result, with a sufficient total cross section of the exhaust slots, such a large distance between the individual exhaust slots can be maintained that the room air can penetrate between the supply air jets emerging from the exhaust slots and can be carried along by induction from the supply air jets. Induction zones are thus formed between the air jets of the individual blow-out slots, which result in high induction and rapid mixing of supply air and room air.

Die Zuluft wird durch die Ausblasschlitze mit hoher Ge­schwindigkeit zugeführt, so daß sich auch bei Änderun­gen des Zuluftvolumenstroms und insbesondere auch bei geringen Zuluftmengen eine stabile Luftwalze ausbildet, die zu einer guten Durchspülung des Raumes führt. In­folge der hohen Induktion wird auch bei geringeren Zu­luftmengen eine ausreichend große Raumluftmenge von den Zuluftstrahlen mitgenommen, um diese stabile Luftwalze aufrechtzuerhalten.The supply air is supplied through the blow-out slots at high speed, so that a stable air roller is formed even when the supply air volume flow changes, and in particular also with small supply air quantities, which leads to a good flushing of the room. As a result of the high induction, a sufficient amount of room air is taken along by the supply air jets even with smaller supply air quantities in order to maintain this stable air roll.

Um die mit verhältnismäßig hohem Druck zugeführte Zu­luft gleichmäßig auf die Ausblasschlitze zu verteilen und ein geräuscharmes Ausströmen der Zuluft zu gewähr­leisten, sind in dem Gehäuse des Fensterschleiergerätes zwischen dem Zuluftanschluß und den Ausblasschlitzen Gleichrichter vorgesehen. Vorzugsweise dienen als Gleichrichter zwei in Strömungsrichtung hintereinander angeordnete Lochbleche, von denen zumindest eines pa­rallel zur Ebene der mit den Ausblasschlitzen versehe­nen Oberseite angeordnet ist.In order to distribute the supply air supplied at a relatively high pressure evenly over the exhaust slots and to ensure a low-noise outflow of the supply air, rectifiers are provided in the housing of the window curtain device between the supply air connection and the exhaust slots. Preferably serve as rectifier two perforated plates arranged one behind the other in the flow direction, at least one of which is arranged parallel to the plane of the top side provided with the blowout slots.

Das Fensterschleiergerät ist ausserordentlich einfach aufgebaut, so daß es in der Herstellung sehr kosten­günstig ist. Das Gerät kann mit kleinen Abmessungen, insbesondere mit einer geringen Tiefen hergestellt wer­den. Es eignet sich dadurch vor allem auch für solche Fälle, bei denen nur ein beschränkter Platz für den Einbau zur Verfügung steht. Wegen der geringen Abmes­sung eignet sich das Fensterschleiergerät besonders auch für den nachträglichen Einbau. Dabei wirkt sich vorteilhaft aus, daß nur eine einzige Zuluftleitung mit geringem Querschnitt benötigt wird.The window curtain is extremely simple, so that it is very inexpensive to manufacture. The device can be manufactured with small dimensions, in particular with a shallow depth. It is therefore particularly suitable for cases in which there is only a limited space available for installation. Because of its small size, the window curtain is particularly suitable for retrofitting. This has the advantageous effect that only a single supply air line with a small cross section is required.

Das Gehäuse 12 ist zusammengesetzt aus einem unteren kas­tenförmigen Gehäuseteil 14 mit rechteckigem Quer­schnitt, auf den ein oberer Gehäuseteil 16 mit etwa quadratischem Querschnitt aufgesetzt ist. Der untere Gehäuseteil 14 und der obere Gehäuseteil 16 weisen ein U-förmiges Profil auf, wobei das obere Gehäuseteil 16 mit seinen Seitenflächen auf die Seitenflächen des un­teren Gehäuseteils 14 aufgeschoben ist. Seitliche Bleche 18 verbinden die beiden Gehäuseteile.The window curtain, which is installed in a window parapet 10, has a flat, elongated, upright, box-shaped housing 12. The housing 12 is composed of a lower box-shaped housing part 14 with a rectangular cross section, on which an upper housing part 16 with an approximately square cross section is placed. The lower housing part 14 and the upper housing part 16 have a U-shaped profile, the upper housing part 16 having its side faces being pushed onto the side faces of the lower housing part 14. Lateral plates 18 connect the two housing parts.

In der langgestreckten horizontalen Oberseite des obe­ren Gehäuseteils 16 sind Ausblasschlitze 20 vorgesehen. Die Ausblasschlitze 20 verlaufen senkrecht zur Längser­streckung des Gehäuses und sind über die gesamte Längs­erstreckung in gleichem gegenseitigem Abstand verteilt. Der Abstand der Ausblasschlitze 20 beträgt dabei ein Mehrfaches ihrer Breite. Die Breite der Ausblasschlitze 20 liegt zwischen etwa 3 mm und 10 mm. Der gegenseitige Abstand der Schlitze beträgt etwa das 4- bis 20-fache ihrer Breite. In dem dargestellten Ausführungsbeispiel weisen die Ausblasschlitze eine Breite von 5 mm und ei­nen gegenseitigen Abstand von 75 mm auf.Blow-out slots 20 are provided in the elongated horizontal upper side of the upper housing part 16. The outlet slots 20 run perpendicular to the longitudinal extent of the housing and are distributed over the entire longitudinal extent at the same mutual distance. The distance between the blow-out slots 20 is a multiple of their width. The width of the blow-out slots 20 is between approximately 3 mm and 10 mm. The mutual spacing of the slots is approximately 4 to 20 times their width. In the exemplary embodiment shown, the blow-out slots have a width of 5 mm and a mutual spacing of 75 mm.

Das Gehäuse 12 ist unten mit einem Zuluftanschluß 22 versehen, der als Stutzen in die Bodenfläche oder in die Seitenfläche eingesetzt ist.The housing 12 is provided at the bottom with a supply air connection 22 which is used as a connector in the bottom surface or in the side surface.

In das Gehäuse 12 sind in dem Strömungsweg der Zuluft von dem Zuluftanschluß 22 zu den Ausblasschlitzen 20 zwei Gleichrichter eingesetzt, die aus Lochblechen 24 und 26 bestehen. Die Lochbleche 24 und 26 sind zwischen die Seitenwände des Gehäuses 12 eingesetzt und mit ab­gebogenen Flanschen an diesen befestigt. Das untere Lochblech 24 ist kreisbogenförmig ausgebildet und wölbt sich über den Zuluftanschluß 22. Die durch den Zuluft­anschluß 22 eintretende Zuluft wird durch dieses untere Lochblech 24 gleichmäßig in alle Richtungen verteilt.In the housing 12 two rectifiers are used in the flow path of the supply air from the supply air connection 22 to the exhaust slots 20, which consist of perforated plates 24 and 26. The perforated plates 24 and 26 are inserted between the side walls of the housing 12 and fastened to them with bent flanges. The lower perforated plate 24 is designed in the form of a circular arc and bulges over the supply air connection 22. The supply air entering through the supply air connection 22 is distributed uniformly in all directions through this lower perforated plate 24.

Das obere Lochblech 26 ist im Bereich der Verbindung von unterem Gehäuseteil 14 und oberem Gehäuseteil 16 angeordnet und erstreckt sich parallel zu der die Aus­blasschlitze 20 aufweisenden Oberseite des Gehäuses über dessen gesamte Längserstreckung. Das obere Loch­blech 26 bewirkt eine gleichmäßige Verteilung der aus dem unteren Gehäuseteil 14 strömenden Zuluft auf alle Ausblasschlitze 20.The upper perforated plate 26 is in the area of the connection arranged from the lower housing part 14 and upper housing part 16 and extends parallel to the top of the housing having the blowout slots 20 over its entire longitudinal extent. The upper perforated plate 26 brings about a uniform distribution of the supply air flowing from the lower housing part 14 over all blowout slots 20.
