Description

Die Erfindung betrifft ein Endstück für Raumklimaanlagen, welches eine Kastenstruktur aufweist, die unterhalb eines als Doppelboden ausgeführten und durch Stützträger auf den Untergrund gestützten Fußbodens angeordnet ist.The invention relates to an end piece for room air conditioning systems, which has a box structure, which is arranged below a floor designed as a double floor and supported by support beams on the ground.

Bekannte Einrichtungen dieser Art werden üblicherweise, besonders dann, wenn der Fußboden als Doppelboden ausgeführt ist, unterhalb des Fußbodenniveaus eingebaut. Die Funktion dieser Endstücke besteht einerseits darin, aus dem Hohlraum unterhalb des Fußbodens von einer zentralen Klimaanlage aufbereitete Frischluft zu entnehmen und sie in einen zu klimatisierenden Raum einzubringen, sowie andererseits darin die Luft des zu klimatisierenden Raumes, eventuell unter Beheizung derselben, umzuwälzen. Dabei kann jeweils die Regelung der Raumparameter, wie z.B. Temperatur oder Luftfeuchtigkeit, durchgeführt werden.Known devices of this type are usually installed below the floor level, especially if the floor is designed as a double floor. The function of these end pieces is, on the one hand, to extract fresh air prepared by a central air conditioning system from the cavity below the floor and to introduce it into a room to be air-conditioned, and on the other hand to circulate the air in the room to be air-conditioned, possibly while heating it. The control of the room parameters, e.g. Temperature or humidity.

Bekannte Endstücke dieser Art umfassen eine unterhalb eines als Doppelboden ausgeführten Fußbodens angeordnete Kastenstruktur, die in eine Luftansaugkammer und eine Gebläsekammer unterteilt ist. Die Luftansaugkammer ist auf einer Seite über ein erstes Bodengitter mit dem zu klimatisierenden Raum und auf der anderen Seite mit dem unterhalb des Fußbodens befindlichen Hohlraum verbunden, in dem sich die Eingänge der Ventilatoren befinden. Die Gebläsekammer wiederum ist auf einer Seite über ein zweites Bodengitter mit dem zu klimatisierenden Raum verbunden, während sie mit ihrer anderen Seite an die Ausgänge der Ventilatoren angeschlossen ist. Die Ansaugkammer ist weiters mit einer Öffnung versehen, durch die klimatisierte Luft aus der zentralen Klimaanlage über den Fußbodenhohlraum angesaugt werden kann, wobei mit Hilfe einer Regelklappe, die Luftströme aus dem ersten Bodengitter und aus der Hohlraumöffnung in beliebig einstellbarem Mischverhältnis zu einem Gesamtluftstrom, der in die Eingänge der Ventilatoren geführt wird, vereint werden.Known end pieces of this type comprise a box structure which is arranged below a floor and is divided into an air suction chamber and a blower chamber. The air intake chamber is connected on one side via a first floor grille to the room to be air-conditioned and on the other side to the cavity below the floor, in which the fan inputs are located. The blower chamber is in turn connected on one side to the room to be air-conditioned via a second floor grille, while the other side is connected to the fan outlets. The suction chamber is also provided with an opening through which conditioned air from the central air conditioning system can be sucked in via the floor cavity, with the help of a control flap, the air flows from the first floor grille and from the cavity opening in an arbitrarily adjustable mixing ratio to a total air flow that is in the inputs of the fans are guided.

Endstücke dieser Art weisen mehrere Nachteile auf, wobei ein wesentlicher Nachteil darin besteht, daß wenigstens zwei Bodengitter benötigt werden, eines zum Ansaugen der Luft für die Ansaugkammer und eines für das Ausblasen der Luft über die Gebläsekammer.End pieces of this type have several disadvantages, a major disadvantage of which is that at least two floor grilles are required, one for sucking in the air for the suction chamber and one for blowing out the air via the blower chamber.

Ein weiterer Nachteil besteht darin, daß diese Endstücke für eine optimale Funktion Ventilatoren benötigen, welche sehr hohen Platzbedarf aufweisen und allein dadurch eine getrennte Anordnung der beiden Bodengitter erfordern. Die von diesen Gittern eingenommene Fläche ist so groß, daß dadurch der Einbau von Endstücken dieser Art aus Platzgründen nicht überall erfolgen kann. Desweiteren stören die durch die Gitter entstehenden, benachbarten Bereiche die Einheitlichkeit des Fußboden und sind daher auch aus ästhetischen Gründen nachteilig.Another disadvantage is that these end pieces require fans for optimal function, which require a very large amount of space and therefore require a separate arrangement of the two floor grilles. The area occupied by these grids is so large that the installation of end pieces of this type cannot take place everywhere for reasons of space. Furthermore, the adjacent areas created by the grids disrupt the uniformity of the floor and are therefore disadvantageous for aesthetic reasons.

Der Erfindung liegt die Aufgabe zugrunde, ein neues Endstück für Raumklimaanlagen zu schaffen, das die oben genannten Nachteile der bekannten Endstücke vermeidet.The invention has for its object to provide a new end piece for room air conditioning, which avoids the disadvantages of the known end pieces mentioned above.

Folglich besteht eine der Aufgaben darin, ein kleineres als gegenwärtige und kompakt dimensioniertes Endstück zu schaffen. Eine weitere wichtige Aufgabe stellt die Schaffung eines Endstückes dar, welches nur ein einziges Bodengitter benötigt. Schließlich ist es auch Aufgabe, ein Endstück zu schaffen, welches mit gewöhnlichem Werkzeug und bisher üblicher Installationstechnik realisierbar ist.Consequently, one of the tasks is to create a smaller than current and compact end piece. Another important task is the creation of an end piece that only requires a single floor grille. Finally, it is also the task to create an end piece that can be realized with ordinary tools and installation technology that has been common up to now.

Dies wird bei einem Endstück der eingangs erwähnten Art erfindungsgemäß dadurch erreicht, daß die Kastenstruktur ein erstes Gehäuse umfaßt, welches mit dem zu klimatisierenden Raum über Mittel zum Luftdurchtritt, wie z.B. ein Bodengitter, in Verbindung steht und welches in wenigstens eine Ansaugkammer und wenigstens eine Gebläsekammer unterteilt ist, wobei die Kammern über zugehörige Öffnungen mit dem Inneren eines zweiten Gehäuses in Verbindung stehen, welches zweite Gehäuse mit wenigstens einer Öffnung zum Lufteintritt, z.B. aus einem Fußbodenhohlraum, versehen ist und in welchem zweiten Gehäuse Mittel zur Steuerung des bzw. der Ansaugluftströme und Mittel zur Luftzirkulation vorgesehen sind. In einem derart ausgeführten Endstück sind Ansaugkammer(n) und Gebläsekammer(n) in einem Gehäuse vereint. Dadurch können die Abmaße des Endstückes verringert werden, wodurch die Verluste beim Lufttransport gering gehalten werden können. Folglich können damit Ventilatoren kleinerer Bauart eingesetzt werden. Zusätzlich ergibt sich aus der kompakten Bauweise auch eine Verringerung der Wärmeverluste, durch die kleinere Oberfläche der Anordnung. Darüberhinaus kann das Endstück als fertige Einheit eingebaut werden und muß nicht aus mehreren Einzelstücken zusammengefügt werden.This is achieved according to the invention in an end piece of the type mentioned at the outset in that the box structure comprises a first housing which communicates with the space to be air-conditioned by means of air passage, such as e.g. a floor grille, which is connected and which is divided into at least one suction chamber and at least one blower chamber, the chambers being connected to the interior of a second housing via associated openings, the second housing having at least one opening for air entry, e.g. from a floor cavity, and in which second housing means are provided for controlling the intake air flow (s) and means for air circulation. In such an end piece, the suction chamber (s) and blower chamber (s) are combined in one housing. The dimensions of the end piece can thereby be reduced, as a result of which the losses during air transport can be kept low. As a result, fans of a smaller design can be used. In addition, the compact design also results in a reduction in heat losses due to the smaller surface area of the arrangement. In addition, the end piece can be installed as a finished unit and does not have to be assembled from several individual pieces.

Gemäß einer weiteren vorteilhaften Ausbildung der Erfindung kann vorgesehen sein, daß Ansaug- und Gebläsekammer ein gemeinsames Mittel zum Luftdurchtritt, wie z.B. ein einstückiges Bodengitter, zugeordnet ist. Ein derartiges einstückiges Bodengitter für beide Kammern senkt die Einbaukosten gegenüber bekannten Endstücken dieser Art, da nur eine Fußbodenausnehmung geschaffen werden muß.According to a further advantageous embodiment of the invention, it can be provided that the suction and blower chamber have a common means for air passage, such as e.g. a one-piece floor grille is assigned. Such a one-piece floor grille for both chambers reduces the installation costs compared to known end pieces of this type, since only one floor recess has to be created.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Mittel zur Steuerung des bzw. der Ansaugluftströme aus einer Klappe gebildet sind, welche so angeordnet ist, daß sie bei Öffnen des bzw. der Ansaugluftströme aus dem zu klimatisierenden Raum den Lufteintritt z.B. aus einem Fußbodenhohlraum regelbar verschließt, insbesonders absperrt, und umgekehrt. Dies ermöglicht es, die Öffnung in die Ansaugkammer zu verschließen und so nur klimatisierte Luft über die Hohlraumöffnung des zweiten Gehäuses mit Hilfe der Ventilatoren anzusaugen und über die Gebläsekammer in den Raum zu befördern. Wird andererseits die Hohlraumöffnung mittels der Klappe geschlossen, kann Luft nur über die Ansaugkammer aus dem Raum zu den Ventilatoren gesaugt und von diesen durch die Gebläsekammer hindurch wieder in den Raum zurückgeführt werden. Letztere Betriebsart entspricht dem Umwälzen der Raumluft. Durch das regelbare, d.h. teilweise Verschließen könnte aber auch eine Mischung der Luft erfolgen.In a further development of the invention, it can be provided that the means for controlling the intake air flow (s) are formed from a flap which is arranged in such a way that when the intake air flow (s) opens, the air inlet can be regulated, for example, from a floor cavity closed, especially closed, and vice versa. This makes it possible to close the opening in the suction chamber and thus to draw in only conditioned air via the cavity opening of the second housing with the aid of the fans and to convey it into the room via the blower chamber. If, on the other hand, the cavity opening is closed by means of the flap, air can only be drawn from the room to the fans via the suction chamber and can be returned to the fans through the fan chamber. The latter operating mode corresponds to the circulation of the room air. By regulating, ie partially closing, the air could also be mixed.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß Mittel zur Regelung von Raumparametern, wie z.B. Temperatur, Luftfeuchtigkeit usw., vorgesehen sind. Die in der zentralen Klimaanlage bereits vorkonditionierte Luft kann durch eine derartige Regelung noch weiter in ihrem Zustand verändert werden. Dies auch deshalb, da aufgrund langer Luftstromwege durch den Fußbodenhohlraum sich die Temperatur oder ein anderer Raumparameter verändern könnte. Weiters kann eine individuelle Regelung der Parameter für unterschiedliche Anforderungen erwünscht sein.According to a further feature of the invention it can be provided that means for controlling room parameters, such as e.g. Temperature, humidity, etc. are provided. The air that has already been preconditioned in the central air conditioning system can be further changed in its state by such a control. This is also because the temperature or another room parameter could change due to long air flow paths through the floor cavity. Furthermore, individual regulation of the parameters for different requirements may be desired.

In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß Ansaugkammer(n) und Gebläsekammer(n) unmittelbar aneinander anschließend angeordnet sind, insbesonders die Ansaugkammer bzw. -kammern die Gebläsekammer(n) zwischen sich aufnimmt bzw. aufnehmen. Eine derart von einer oder mehrerer Ansaugkammern umgebene Gebläsekammer bzw. - kammern erzeugt einen gerichteten Luftstrom in den zu klimatisierenden Raum, wobei die Luft bei Beheizung im Endstück aufgrund ihrer niederen Dichte im Raum aufsteigt, während die im bezug auf die Gebläsekammer außen angebrachten Ansaugkammern die nach dem Durchströmen des Raumes kühlere Luft ansaugen.In a further embodiment of the invention, it can be provided that the suction chamber (s) and blower chamber (s) are arranged directly adjacent to one another, in particular the suction chamber or chambers holds the blower chamber (s) between them. A blower chamber or chambers surrounded in this way by one or more suction chambers generates a directed air flow into the room to be air-conditioned, the air rising when heated in the end piece due to its low density in the room, while the suction chambers mounted on the outside in relation to the blower chamber follow suck in cooler air as it flows through the room.

Eine weitere bevorzugte Ausführungsform der Erfindung ist, daß das erste Gehäuse nach oben gegen die Mittel zum Luftdurchtritt, wie z.B. das Bodengitter offen ausgebildet ist. Ein derart nach oben offenes erstes Gehäuse bewirkt einen gerichteten Luftstrom aus der Gebläsekammer nach oben, wodurch zuerst eine Bewegung der klimatisierten Luft auf dem kürzesten Weg in den oberen Teil des zu klimatisierenden Raumes hinein erreicht wird. Danach kann dieses Luftvolumen über den ganzen Raum verteilt auf die sich im unteren Teil des Raumes befindlichen Personen niedersenken. Bei nachfolgendem Absinken auf Bodenniveau ist die Luft durch Atmungsvorgänge verbraucht, d.h. ihr Sauerstoffgehalt ist niedriger als zuvor, und, so sie vorher beheizt war, abgekühlt. Am Boden wird diese verbrauchte Luft nun über das Bodengitter und die Ansaugkammer(n) der Klimaanlage wieder zugeführt. Somit ergibt sich eine günstige Zirkulation der Luft, wobei sich der Gebläse- und der Ansaugstrom nur sehr wenig beeinflussen.Another preferred embodiment of the invention is that the first housing upwards against the means for air passage, e.g. the floor grille is open. Such a first housing, which is open at the top, causes a directed air flow out of the blower chamber, as a result of which firstly a movement of the conditioned air is achieved in the shortest way into the upper part of the room to be conditioned. Then this volume of air can be distributed over the entire room to the people in the lower part of the room. When it subsequently drops to ground level, the air is used up by breathing processes, i.e. its oxygen content is lower than before and, if it was previously heated, cooled. On the floor, this used air is now fed back into the air conditioning system via the floor grille and the suction chamber (s). This results in a favorable circulation of the air, with the fan and intake flow having only very little influence.

Ein weiteres Merkmal der Erindung besteht darin, daß das erste Gehäuse in der Form eines nach oben gegen die Mittel zum Luftdurchtritt, wie z.B. das Bodengitter, offenen Parallelepipeds ausgebildet ist, welches durch vertikale Wände in zwei äußere Ansaugkammern und eine dazwischen angeordnete Gebläsekammer unterteilt ist. Durch diese Anordnung umgeben die Ansaugkammern die Gebläsekammer in einer strömungstechnisch günstigen Weise. Weiters finden die Kammern unter einem rechteckigen Bodengitter Platz, sodaß Raumluft durch dasselbe Gitter in die Ansaugkammern eintreten und klimatisierte Luft austreten kann. Durch diese Ausbildung ist die Erfindung aber keineswegs eingeschränkt. Die Gebläsekammer kann beispielsweise zylinderförmig und die Ansaugkammer in der Form eines die Gebläsekammer umgebenden Hohlzylinders ausgebildet sein, bzw. können mehrere Ansaugkammern durch Teile eines solchen Hohlzylinders gebildet sein. In diesem Fall könnte die Ab- und Zuluft durch ein kreisförmiges Bodengitter hindurchtreten.Another feature of the invention is that the first housing is in the form of an parallelepiped open upwardly against the air passage means such as the floor grille, which is divided by vertical walls into two outer suction chambers and a blower chamber located therebetween. With this arrangement, the suction chambers surround the blower chamber in a fluidically favorable manner. Furthermore, the chambers are located under a rectangular floor grille so that room air can enter the intake chambers through the same grille and conditioned air can escape. However, the invention is in no way restricted by this design. The blower chamber can be cylindrical, for example, and the suction chamber can be in the form of a hollow cylinder surrounding the blower chamber, or a plurality of suction chambers can be formed by parts of such a hollow cylinder. In this case, the exhaust and supply air could pass through a circular floor grille.

In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß die Gebläsekammer Mündungsöffnungen für die Mittel zur Luftzirkulation aufweist. An derartigen Mündungsöffnungen können die Ventilatoren druckdicht befestigt werden, sodaß kein Druckausgleich zwischen Ansaug- und Gebläseseite erfolgen kann.In a further embodiment of the invention it can be provided that the blower chamber has orifices for the means for air circulation. At such mouth openings, the fans can be attached in a pressure-tight manner, so that there can be no pressure compensation between the suction and blower sides.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß die Mittel zur Luftzirkulation aus zwei Ventilatoren gebildet sind, welche gemeinsam von einem einzigen elektrischen Motor angetrieben sind, wobei der Motor mit dem ersten Gehäuse fest verbunden ist. Die Aufteilung des Luftstroms auf zwei Ventilatoren bringt strömungstechniche Vorteile mit sich, da die Wirbelbildung und damit Reibungsverluste vermindert werden.According to a further feature of the invention it can be provided that the means for air circulation are formed from two fans, which are driven together by a single electric motor, the motor being firmly connected to the first housing. The division of the air flow between two fans has advantages in terms of flow technology, since the formation of eddies and thus friction losses are reduced.

Gemäß einer weiteren vorteilhaften Ausbildung der Erfindung kann vorgesehen sein, daß die Ansaugkammern Öffnungen aufweisen, die im Boden des ersten Gehäuses angebracht sind. Über solche Öffnungen kann der Luftstrom aus dem zu klimatisierenden Raum angesaugt werden, um über die Klappe und die Ventilatoren in die Gebläsekammer zu gelangen und von dort wieder in den Raum.According to a further advantageous embodiment of the invention it can be provided that the suction chambers have openings which are made in the bottom of the first housing. The air stream can be sucked in from the room to be air-conditioned via such openings in order to get into the blower chamber via the flap and the fans and from there back into the room.

Eine weitere bevorzugte Ausführungsform besteht darin, daß die Klappe um eine horizontale Achse zwischen einer ersten und zweiten Stellung drehbar ist, wobei in der ersten Stellung die Öffnungen der Ansaugkammern geschlossen sind und in der zweiten Stellung der Durchtritt der aus dem Fußbodenhohlraum stammenden Luft zu den Ventilatoren gesperrt ist, wobei in dieser Stellung die Klappe auf dem Boden des zweiten Gehäuses aufliegt. Die zwischen diesen beiden Endstellen kontinuierlich verstellbare Klappe kann in verschiedene Positionen gebracht werden und steht dabei so in bezug auf die Öffnungen, daß sich der klimatisierte Luftstrom aus den Ansaugkammern im selben Maße vergrößert als sich der Luftstrom von der Klimaanlage verkleinert.Another preferred embodiment is that the flap is rotatable about a horizontal axis between a first and a second position, the openings of the suction chambers being closed in the first position and the passage of the air coming from the floor cavity to the fans in the second position is locked, in which position the flap rests on the bottom of the second housing. The flap, which is continuously adjustable between these two end points, can be brought into different positions and is so positioned in relation to the openings that the conditioned air flow from the suction chambers increases to the same extent as the reduced air flow from the air conditioning system.

In weiterer Ausbildung der Erfindung kann vorgesehen sein, daß das zweite Gehäuse eine wannenförmige Struktur aufweist und mit einer im Bereich der Klappe angeordneten Ansaugöffnung versehen ist, die mit dem Fußbodenhohlraum in Verbindung steht. Durch eine derartige Hohlraumöffnung kann klimatisierte Frischluft angesaugt werden, wobei die Stärke dieses Luftstroms von der Stellung der Klappe beeinflusst wird.In a further embodiment of the invention it can be provided that the second housing has a trough-shaped structure and is provided with a suction opening which is arranged in the region of the flap and which is connected to the floor cavity. Air-conditioned fresh air can be sucked in through such a cavity opening, the strength of this air flow being influenced by the position of the flap.

Schließlich besteht eine weitere Ausführungsform der Erfindung der Erfindung darin, daß die Klappe an einen Motorwickler angekoppelt ist. Durch einen Motorwickler kann die Klappe in eine bestimmte Stellung bewegt werden, sodaß je nach Stellung der Klappe ein bestimmtes Mischverhältnis von Frisch- und Umwälzluft vorliegt.Finally, a further embodiment of the invention of the invention is that the flap is coupled to a motor winder. The flap can be moved into a certain position by a motor winder, so that depending on the position of the flap there is a certain mixing ratio of fresh and circulating air.

Im folgenden wird die Erfindung anhand der Zeichnungen beispielsweise erläutert. Es zeigt:
