Description

Die Erfindung betrifft einen Deckenkonvektor mit einem Wärmetauscher mit ungefähr rechteckigem Querschnitt, wobei Raumluft durch eine Eintrittsfläche in den Wärmetauscher eintritt.The invention relates to a ceiling convector with an approximately rectangular heat exchanger Cross-section, with room air entering the heat exchanger through an entry surface.

Deckenkonvektoren werden zur Kühlung oder Heizung von Raumluft eingesetzt. Sie werden in großen Räumen unter abgehängten Decken oder auch - beispielsweise in Verkaufsräumen - offen sichtbar montiert. Häufig wird auch die Zuführung von Frischluft oder vorkonditionierter Luft in eine solche Anordnung integriert.Ceiling convectors are used for cooling or heating room air. you will be in large rooms under suspended ceilings or - for example in sales rooms - mounted open and visible. The supply of fresh air or pre-conditioned is often also Air integrated into such an arrangement.

Eine Vorrichtung der eingangs beschriebenen Art ist beispielsweise aus dem deutschen Gebrauchsmuster 298 19 596 bekannt. Der dort vorgestellte Deckenkonvektor mit rechteckigem Grundriß ist mit zwei getrennten, in Längsrichtung des Konvektors angeordneten Wärmetauschern ausgestattet, deren Höhe deutlich größer ist als ihre Breite. Die senkrecht von unten mittig in den Deckenkonvektor einströmende Raumluft wird in einem Raum zwischen den Wärmetauschern umgelenkt und durchströmt diese geradlinig horizontal zu beiden Seiten. Oberhalb der Wärmetauscher und an diese unmittelbar angrenzend befindet sich ein ebenfalls in Längsrichtung des Deckenkonvektors verlaufender Luftverteilkasten mit seitlich der Wärmetauscher angeordneten Düsen. Durch die aus diesen Düsen strömende Zuluft wird die aus den Wärmetauschern strömende Luft wiederum umgelenkt und strömt senkrecht nach unten. Luftleitbleche lenken die ausströmende Luft noch einmal zu beiden Seiten um bevor sie den Konvektor durch die Ausströmöffnungen verläßt.A device of the type described at the outset is, for example, from German Utility model 298 19 596 known. The ceiling convector presented there with a rectangular one Floor plan is with two separate heat exchangers arranged in the longitudinal direction of the convector equipped, the height of which is significantly greater than its width. The perpendicular from Room air flowing down into the middle of the ceiling convector is located in a room between deflected the heat exchangers and flows straight through them horizontally on both sides. Above and immediately adjacent to the heat exchanger is a in the longitudinal direction of the ceiling convector air distribution box with the side Heat exchanger arranged nozzles. Due to the supply air flowing from these nozzles Air flowing out of the heat exchangers in turn is redirected and flows in vertically below. Air baffles redirect the escaping air to both sides it leaves the convector through the outflow openings.

Aus dem deutschen Gebrauchsmuster 296 09 754 ist eine weitere Bauform eines Deckenkonvektors mit rechteckigem Grundriß bekannt, der mit einem einzelnen, in seiner Längsrichtung angeordneten Wärmetauscher ausgestattet ist, wobei die Höhe des Wärmetauschers deutlich geringer ist als seine Breite. Nach dem Eintritt in den Deckenkonvektor wie in der zuvor beschriebenen Vorrichtung strömt die Raumluft geradlinig vertikal von unten nach oben durch den Wärmetauscher. Der Luftverteilkasten ist in dieser Bauform in einem Raum oberhalb des Wärmetauschers angeordnet, die Düsen weisen zu beiden Seiten schräg nach unten. Die aus dem Wärmetauscher ausströmende Raumluft wird durch die aus den Düsen strömende Zuluft zu beiden Seiten umgelenkt und verläßt den Konvektor durch die Ausströmöffnungen.Another design of a ceiling convector is from German utility model 296 09 754 known with a rectangular plan, with a single, in its longitudinal direction arranged heat exchanger is equipped, the height of the heat exchanger clearly is less than its width. After entering the ceiling convector as in the previously described The device flows straight through the room air vertically from bottom to top the heat exchanger. The air distribution box is in this design in a room above the Heat exchanger arranged, the nozzles point obliquely downwards on both sides. From Room air flowing out of the heat exchanger is replaced by the supply air flowing out of the nozzles deflected on both sides and leaves the convector through the outflow openings.

Den bekannten Vorrichtungen gemeinsam ist die relativ große Bauhöhe, die aus der gradlinigen Durchströmung der Wärmetauscher resultiert. Diese konstruktive Eigenheit erschwert oder verhindert den Einbau der bekannten Konvektoren in Räumen mit geringen Deckenhöhen, so daß oftmals auf stehende Klimatisierungsvorrichtungen zurückgegriffen werden muß. Abgesehen von der benötigten Stellfläche auf dem Boden sind derartige Geräte aber häufig nicht in der Lage, gerade große Räume gleichmäßig zu klimatisieren. Darüber hinaus führen die bodennahen Auslaßöffnungen zu unerwünschten Zuglufteffekten.Common to the known devices is the relatively large overall height, which results from the straight line Flow through the heat exchanger results. This constructive peculiarity complicates or prevents the installation of the known convectors in rooms with low ceiling heights, so that standing air conditioning devices often have to be used. Apart from the floor space required, such devices are common unable to evenly air condition large rooms. Lead beyond the outlet openings near the floor for undesirable drafts.

Aufgabetask

Aufgabe der Erfindung ist es, insbesondere für die Verwendung in Räumen mit geringen Deckenhöhen, einen Deckenkonvektor mit deutlich reduzierter Bauhöhe vorzuschlagen, mit dem nicht nur die Materialkosten des Konvektors selbst, sondern auch die Baukosten insgesamt durch geringere Zwischendeckenhöhen reduziert werden können.The object of the invention is, in particular for use in rooms with low ceiling heights, propose a ceiling convector with a significantly reduced overall height, with which not only the material costs of the convector itself, but also the overall construction costs can be reduced by lower false ceiling heights.

Lösungsolution

Ausgehend von der eingangs beschriebenen Vorrichtung wird diese Aufgabe nach der Erfindung dadurch gelöst, daß Raumluft aus einer zur Eintrittsfläche senkrechten Fläche des Wärmetauschers austritt. Auf diese Weise kann der in Einströmrichtung hinter dem Wärmetauscher liegende Raum entfallen oder mindestens in seiner Größe deutlich reduziert werden.Starting from the device described in the introduction, this object is achieved according to the invention solved in that room air from a surface of the heat exchanger perpendicular to the inlet surface exit. In this way it can be downstream of the heat exchanger lying space is eliminated or at least significantly reduced in size.

Der Vorteil der reduzierten Bauhöhe des Deckenkonvektors wird insbesondere dann zum Tragen kommen, wenn die Raumluft in eine horizontale Fläche des Wärmetauschers, bevorzugt nach oben eintritt. Eine unter diesem Aspekt besonders ausgezeichnete Bauform ist mit einem flachen Wärmetauscher ausgestattet, dessen Breite deutlich höher ist als seine Höhe.The advantage of the reduced height of the ceiling convector is then particularly Wear come when the indoor air is preferred in a horizontal surface of the heat exchanger enters upwards. A particularly excellent design from this point of view is with equipped with a flat heat exchanger, the width of which is significantly greater than its height.

Die erfindungsgemäße Führung der Strömung der Raumluft läßt sich sowohl bei balken- als auch bei zylinderförmigen Wärmetauschern in Deckenkonvektoren mit entsprechend rechteckigem oder kreisförmigem Grundriß realisieren. The inventive guiding of the flow of the room air can be carried out both with beams even with cylindrical heat exchangers in ceiling convectors with a corresponding rectangular shape or circular floor plan.

Die Erfindung weiter ausgestaltend ist vorgesehen, das Wärmeträgermedium in Leitungen durch den Wärmetauscher zu führen, die Lamellen aufweisen. Auf diese Weise wird der Wärmeübergang zwischen Raumluft und Wärmeträgermedium wesentlich erhöht. Der durchströmte Querschnitt des Wärmetauschers kann bei gleichbleibender Leistung deutlich verringert werden.The invention is further developed, the heat transfer medium in lines through the heat exchanger, which have fins. In this way the Heat transfer between room air and heat transfer medium significantly increased. The flowed through Cross section of the heat exchanger can be significantly reduced while maintaining the same performance become.

Die erfindungsgemäße Strömungsführung wird dadurch erreicht, daß die Strömung durch die der Eintrittsfläche gegenüber liegende Fläche des Wärmetauschers verhindert wird. Konstruktiv besonders einfach ist dies durch eine Abdeckung dieser Fläche zu realisieren. Vorteilhaft ist es auch, die der Eintrittsfläche gegenüber liegende Begrenzungsfläche nur teilweise zu verschließen oder eine Wand in geringem Abstand von dieser Fläche vorzusehen. Insbesondere bei Bauformen mit breitem Wärmetauscher wird so eine Strömung von Raumluft auch durch den mittleren Bereich des Wärmetauschers erreicht.The flow control according to the invention is achieved in that the flow through the the surface of the heat exchanger opposite the inlet surface is prevented. constructive This is particularly easy to implement by covering this area. Advantageous it is also the case that the boundary surface lying opposite the entry surface is only partially closed close or provide a wall a short distance from this surface. In particular With designs with a wide heat exchanger, there is also a flow of indoor air reached through the central area of the heat exchanger.

Die erfindungsgemäße Führung der Raumluft wird besonders einfach dadurch erreicht, daß zur Eintrittsfläche senkrechte Begrenzungsflächen des Wärmetauschers nicht verschlossen sind. Vorteilhaft ist jedoch insbesondere eine Ausgestaltung der Erfindung dahingehend, daß diese Flächen an den den Eintrittsflächen zugewandten Enden verschlossen sind. Auf diese Weise wird verhindert, daß ein Teil der den Deckenkonvektor durchströmenden Raumluft den Wärmetauscher nicht oder nur auf einer sehr kurzen Strecke durchströmt.The guidance of the room air according to the invention is achieved particularly simply in that Boundary surfaces of the heat exchanger perpendicular to the inlet surface are not closed are. However, an embodiment of the invention is particularly advantageous in that these surfaces are closed at the ends facing the entry surfaces. To this This prevents a part of the room air flowing through the ceiling convector Heat exchanger does not flow through or only over a very short distance.

Bei erhöhten Anforderungen an den Durchsatz der Raumluft, das heißt zur Vergrößerung der Leistung des Deckenkonvektors läßt sich die erfindungsgemäße Vorrichtung mit bekannten Einrichtungen kombinieren, die der Raumluft eine Strömung aufprägen. Zu diesem Zweck .können zum Beispiel einer oder mehrere Ventilatoren eingesetzt werden.With increased demands on the throughput of the room air, that is, to increase the Performance of the ceiling convector, the device according to the invention can be known Combine facilities that impart a flow to the room air. To this end For example, one or more fans can be used.

Auch die Zuführung von Frischluft oder konditionierter Luft ist mit der erfindungsgemäßen Vorrichtung gut zu kombinieren. Möglich ist die Verwendung eines über dem Wärmetauscher angeordneten Luftverteilkastens. Die Aufgabe der Minimierung der Bauhöhe wird wiederum dann besonders gut gelöst, wenn Zuluft über Verteilkästen seitlich des Wärmetausches zugeführt wird. Zur Verringerung der Materialkosten bietet es sich an, Düsen zur Zuführung von Zuluft unmittelbar an den oder die Verteilkästen anzuformen. So können die Düsen zum Beispiel durch Umformung aus dem Material der Wandungen des oder der Luftverteilkästen herausgearbeitet seinThe supply of fresh air or conditioned air is also possible with the invention Combine the device well. It is possible to use one above the heat exchanger arranged air distribution box. The task of minimizing the overall height is in turn then particularly well solved if supply air is supplied via distribution boxes to the side of the heat exchange becomes. To reduce the material costs, it is advisable to use nozzles for feeding To form supply air directly on the distribution box or boxes. For example, the nozzles worked out by reshaping the material of the walls of the air distribution box or boxes his

Der Verringerung der Baukosten dient auch die Verwendung eines Deckenkonvektors sowohl zur Kühlung als auch bei Bedarf zur Heizung der Raumluft. Hierbei ist es insbesondere vorteilhaft, wenn getrennte Leitungssysteme in demselben Lamellenpaket des Wärmetauschers angeordnet sind.The use of a ceiling convector also serves to reduce construction costs for cooling as well as for heating the room air if required. It is particularly advantageous here if separate pipe systems in the same plate pack of the heat exchanger are arranged.

Innerhalb des Luftverteilkastens 18 ist (wie auch in dem folgenden Ausführungsbeispiel) ein Anschlußstutzen für die Versorgung des Luftverteilkastens 18 mit Zuluft 23 angedeutet.Above the heat exchanger 11 is a running in the longitudinal direction of the ceiling convector 10 Air distribution box 18 is arranged with a rectangular cross section, the upper horizontal boundary surface 16 of the heat exchanger opposite the inlet surface 25 11 closes. Inside the air distribution box 18 is (as in the following Embodiment) with a connecting piece for the supply of the air distribution box 18 Supply air 23 indicated.

An den über den Wärmetauscher 11 hinausragenden Abschnitten des Luftverteilkastens 18 sind senkrecht nach unten weisende Düsen 19 angebracht. Die aus den Düsen 19 senkrecht nach unten ausströmende Zuluft 23 lenkt die aus dem Wärmetauscher 11 ungefähr waagerecht ausströmende Raumluft 22 senkrecht nach unten in Richtung der Auslaßöffnung 27 um, wo ihr die inneren und äußeren Luftleitbleche 17 und 20 eine waagrechte Komponente aufprägen.At the portions of the air distribution box 18 that protrude beyond the heat exchanger 11 are arranged vertically downward nozzles 19. From the nozzles 19 vertically supply air 23 flowing downward directs the heat exchanger 11 approximately horizontally outflowing room air 22 vertically downwards in the direction of the outlet opening 27, where you stamp the inner and outer air baffles 17 and 20 a horizontal component.

Der Deckenkonvektor 10 kann dergestalt in eine (nicht dargestellte) abgehängte Decke montiert sein, daß die äußeren Luftleitbleche 20 mit der Unterseite der abgehängten Decke bündig abschließen. Die aus den Auslaßöffnungen 27 des Deckenkonvektors 10 ausströmende Raumluft 24 strömt dann zumindest teilweise entlang der Decke, wodurch als unangenehm empfundene Luftströme vermieden werden.The ceiling convector 10 can thus be mounted in a suspended ceiling (not shown) be that the outer air baffles 20 are flush with the underside of the suspended ceiling to lock. The room air flowing out of the outlet openings 27 of the ceiling convector 10 24 then flows at least partially along the ceiling, making those felt uncomfortable Air flows can be avoided.

Der in Fig. 2 dargestellte Deckenkonvektor 30 unterscheidet sich von der Ausführungsform 10 gemäß Fig. 1 durch einen vertikalen Abstand zwischen der oberen Begrenzungsfläche 36 des Wärmetauschers 31 und dem Luftverteilkasten 38. Zusätzlich zu den seitlichen senkrechten Begrenzungsflächen 35 des Wärmetauschers 31 wird hier auch die obere Begrenzungsfläche 36 zu einer Austrittsfläche 46 der Raumluft 42 aus dem Wärmetauscher 31. Diese Variante ermöglicht bei breiten Bauformen des eingesetzten Wärmetauschers eine Durchströmung des mittleren Bereiches des Querschnitts und eine bessere Ausnutzung der zur Verfügung stehenden Wärmeleistung. Außerdem sind die seitlichen senkrechten Begrenzungsflächen 35 des Wärmetauschers 31 an den der Einströmfläche 45 zugewanden Seiten verschlossen. Durch diese konstruktive Maßnahme wird verhindert, daß ein Teil der den Deckenkonvektor 30 durchströmenden Raumluft den Wärmetauscher 31 nur auf einer sehr kurzen Strecke durchströmt.The ceiling convector 30 shown in FIG. 2 differs from the embodiment 10 by a vertical distance between the upper boundary surface 36 of the heat exchanger 31 and the air distribution box 38. In addition to the lateral vertical Boundary surfaces 35 of the heat exchanger 31 also become the upper boundary surface 36 to an exit surface 46 of the room air 42 from the heat exchanger 31. This variant enables flow through with wide designs of the heat exchanger used of the central area of the cross section and better utilization of the available standing heat output. In addition, the lateral vertical boundary surfaces 35 of the heat exchanger 31 is closed on the sides facing the inflow surface 45. This constructive measure prevents part of the ceiling convector 30 room air flowing through the heat exchanger 31 only over a very short distance flows through.

Der in Fig. 3 dargestellte Deckenkonvektor 50 ist eine alternative Ausführungsform mit einem in Längsrichtung des Deckenkonvektors 50 zweigeteilten Luftverteilkasten 58 mit dreieckigem Querschnitt. Die beiden getrennten Luftverteilkästen 58 sind zu beiden Seiten an der Unterseite des Wärmetauschers 51 angeordnet. Die obere Begrenzungsfläche 56 des Wärmetauschers 51 ist verschlossen.The ceiling convector 50 shown in FIG. 3 is an alternative embodiment with a in the longitudinal direction of the ceiling convector 50 two-part air distribution box 58 with a triangular Cross-section. The two separate air distribution boxes 58 are on either side Bottom of the heat exchanger 51 is arranged. The upper boundary surface 56 of the heat exchanger 51 is closed.

Die Raumluft 61 strömt senkrecht nach oben in den Wärmetauscher 51 ein, wobei die auf einander zu gerichteten Wandungen der Luftverteilkästen 58 außerdem die Funktion der hier nicht vorhandenen inneren Luftleitbleche übernehmen. Wie beim zuvor beschriebenen Deckenkonvektor 10 wird die Raumluft 62 im Innern des Wärmetauschers 51 umgelenkt und strömt durch die seitlichen senkrechten Begrenzungsflächen 55 aus dem Wärmetauscher 51 heraus. Die aus den an die Luftverteilkästen 58 angebrachten Düsen 59 ausströmende Zuluft 63 vermischt sich mit der aus dem Wärmetauscher 51 infolge von Induktion ausströmenden Raumluft 62 und prägt dieser eine Strömung in horizontaler Richtung auf. The room air 61 flows vertically upwards into the heat exchanger 51, the on mutually facing walls of the air distribution boxes 58 also the function of here Take over internal air baffles that are not present. As with the ceiling convector described above 10, the room air 62 is redirected inside the heat exchanger 51 and flows out of the heat exchanger 51 through the lateral vertical boundary surfaces 55 out. The supply air flowing out of the nozzles 59 attached to the air distribution boxes 58 63 mixes with that flowing out of the heat exchanger 51 as a result of induction Room air 62 and imprints this on a flow in the horizontal direction.

Der in Fig. 4 dargestellte Deckenkonvektor 70 unterscheidet sich von der Ausführungsform 50 gemäß Fig. 3 durch einen vertikalen Abstand zwischen der oberen Begrenzungsfläche 76 des Wärmetauschers 71 und der in der Figur angedeuteten Raumdecke. Wie beim Deckenkonvektor 30 gemäß Fig. 2 wird auch hier zusätzlich zu den seitlichen senkrechten Begrenzungsflächen 75 des Wärmetauschers 71 auch die obere Begrenzungsfläche 76 zu einer Austrittsfläche 86 der Raumluft aus dem Wärmetauscher 71. Auch hier ermöglicht diese Variante bei breiten Bauformen des eingesetzten Wärmetauschers 71 eine Durchströmung des mittleren Querschnittsbereiches und eine bessere Ausnutzung der zur Verfügung stehenden Wärmeleistung.The ceiling convector 70 shown in FIG. 4 differs from the embodiment 50 by a vertical distance between the upper boundary surface 76 of the heat exchanger 71 and the ceiling indicated in the figure. As with the ceiling convector 30 according to FIG. 2 is also used here in addition to the lateral vertical boundary surfaces 75 of the heat exchanger 71 also the upper boundary surface 76 to an outlet surface 86 of the room air from the heat exchanger 71. This variant also makes possible here with wide designs of the heat exchanger 71 used, a flow through the middle Cross-sectional area and better utilization of the available heat output.

Der in Fig. 5 dargestellte Deckenkonvektor 90 mit passiver Luftführung weist im Gegensatz zu den zuvor beschriebenen Ausführungsformen keine Einrichtung zur Zuführung von Zuluft auf. Die obere Begrenzungsfläche 96 des Wärmetauschers 91 ist verschlossen. Unterhalb des Wärmetauschers 91 sind zu beiden Seiten in Ausdehnungsrichtung des Deckenkonvektors 90 senkrechte Luftleitbleche 107 angebracht.The ceiling convector 90 shown in FIG. 5 with passive air guidance points in contrast no device for supplying air to the previously described embodiments on. The upper boundary surface 96 of the heat exchanger 91 is closed. Below the Heat exchangers 91 are on both sides in the direction of expansion of the ceiling convector 90 vertical air baffles 107 attached.

Die Raumluft 101 strömt durch Eintrittsflächen 105, die durch die senkrechten Begrenzungsflächen 95 des Wärmetauschers 91 gebildet sind, horizontal in den Wärmetauscher 91 ein, wird wiederum innerhalb des Wärmetauschers 91 umgelenkt und strömt durch die untere horizontale Begrenzungsfläche 94 wieder heraus. Durch eine Kaminwirkung zwischen den Luftleitblechen 107 erzeugt die ausströmende Raumluft 102 einen Sog durch den Wärmetauscher 91, der die Strömung aufrecht erhält. Mit den wie dargestellt unterhalb des Wärmetauschers 91 angeordneten Luftleitblechen 107 ist diese Bauform nur zur Kühlung von Raumluft zu verwenden.The room air 101 flows through entry surfaces 105, which pass through the vertical boundary surfaces 95 of the heat exchanger 91 are formed, horizontally into the heat exchanger 91, is in turn deflected within the heat exchanger 91 and flows through the lower horizontal Boundary surface 94 out again. Through a chimney effect between the air baffles 107, the outflowing room air 102 creates suction through the heat exchanger 91, which maintains the current. With the as shown below the heat exchanger 91 arranged air baffles 107, this design is only for cooling room air use.

Der in Fig. 6 dargestellte Deckenkonvektor 110 unterscheidet sich von der Ausführungsform 90 in Fig. 5 durch einen vertikalen Abstand zwischen einer offenen oberen Begrenzungsfläche 116 des Wärmetauschers 111 und der in der Figur angedeuteten Raumdecke. Zusätzlich zu den seitlichen senkrechten Begrenzungsflächen 115 des Wärmetauschers 111 wird hier auch die obere Begrenzungsfläche 116 zu einer Eintrittsfläche 125 der Raumluft 121 in den Wärmetauscher 111. Wiederum ermöglicht diese Variante bei breiten Bauformen des eingesetzten Wärmetauschers 111 eine Durchströmung des mittleren Querschnittsbereiches und eine bessere Ausnutzung der zur Verfügung stehenden Kühlleistung.The ceiling convector 110 shown in FIG. 6 differs from the embodiment 90 in Fig. 5 by a vertical distance between an open upper boundary surface 116 of the heat exchanger 111 and the ceiling indicated in the figure. additionally becomes the lateral vertical boundary surfaces 115 of the heat exchanger 111 here also the upper boundary surface 116 to an entry surface 125 of the indoor air 121 in the Heat exchanger 111. Again, this variant allows for wide designs of the used Heat exchanger 111 a flow through the central cross-sectional area and better utilization of the available cooling capacity.
