Description

Die vorliegenden Erfindung betrifft einen Auslaß, insbesondere zum Einbringen von kalter Luft in einen Raum, mit einem Gehäuse aus Seitenwänden und einer raumseitigen Abdeckplatte mit Auslässen.The present invention relates to an outlet, in particular for introducing cold air into a room, with a housing made of side walls and a cover plate on the room side with outlets.

Auslässe, zum Einbringen von frischer Luft in Innenräume, sind bekannt und weit verbreitet. In den meisten Fällen handelt es sich dabei um ganze Belüfungssysteme, wobei Decken- oder Wandauslässe einerseits einen Drallauslaß od. dgl. aufweisen und andererseits einen Anschlußstutzen, insbesondere an einen Tunnelkasten, für einen Luftkanal besitzen.Outlets for introducing fresh air into interiors are known and widely used. In most cases, these are entire ventilation systems, ceiling or wall outlets on the one hand having a swirl outlet or the like and on the other hand having a connecting piece, in particular to a tunnel case, for an air duct.

Solche Systeme sind geeignet Frischluft insbesondere von außen in Räume einzubringen und zwar mit Hilfe von Ventilatoren od. dgl.. Dabei wird die Luft über weite Strecken geführt und dabei kaum abgekühlt. D.h., sie wird im großen und ganzen so weitergegeben, wie sie von außen aufgenommen wird.
oll die Temperatur in einem Raum verändert insbesondere abgekühlt werden, so ist es notwendig, in ein Belüftungssystem ein Aggregat einzubauen, welches für eine entsprechende Kühlung sorgt. In den meisten Fällen wird für solche Erfordernisse eine aufwendige Klimaanlage eingerichtet oder es werden Kälteaggregate installiert, die mit speziellen Kühlmitteln, insbesondere mit umweltschädlichen oder schwer entsorgbaren Kühlmitteln (CKW) betrieben werden.Such systems are suitable for introducing fresh air into rooms, in particular from the outside, with the aid of fans or the like. The air is guided over long distances and is hardly cooled. That is, it is largely passed on as it is received from the outside.
If the temperature in a room is changed, in particular if it is to be cooled, it is necessary to install a unit in a ventilation system, which ensures appropriate cooling. In most cases, a complex air-conditioning system is set up for such requirements or cooling units are installed which are operated with special coolants, in particular with coolants which are harmful to the environment or difficult to dispose of (CHC).

Für kleinere Räume bedeutet eine Klimaanlage einen großen finanziellen und arbeitsintensiven Aufwand, der zum erreichten Nutzen oft in großem Mißverhältnis steht. Eine Anlage mit speziellen Kühlmitteln soll heute aus Gründen des Umweltschutzes umgangen werden. Außerdem müssen bei beiden Einrichtungen in den meisten Fällen große bauliche Veränderungen vorgenommen werden.For smaller rooms, air conditioning means a great deal of financial and labor-intensive work, which is often disproportionate to the benefits achieved. A plant with special coolants is to be bypassed today for reasons of environmental protection. In addition, in most cases, major structural changes must be made to both facilities.

Der Erfinder hat sich nun zur Aufgabe gestellt, einen Auslaß zu konzipieren, der einerseits zur Installation keine großen baulichen Veränderungen bedarf und fast überall leicht anzubringen ist und der andererseits für die Umwelt keine Belastung, auch im Hinblick auf eine spätere Entsorgung, darstellt.The inventor has now set himself the task of designing an outlet which, on the one hand, does not require any major structural changes for installation and is easy to install almost anywhere and, on the other hand, does not represent a burden on the environment, also with regard to later disposal.

Zur Lösung dieser Aufgabe führt ein Auslaß der o.g. Art, bei der in das Gehäuse ein Kältesatz eingesetzt ist.An outlet of the above leads to the solution of this task. Type in which a refrigeration unit is inserted in the housing.

Bei einem solchen Auslaß besteht der Kältesatz aus einer runden oder etwa quadratischen Umkleidung, welche nach oben hin eine Schulter ausbildet. Die Schulter formt dabei eine insbesondere runde Öffnung aus, welcher ein zylinder-, kamin- oder trichterförmiger Lufteinlaß aufgesetzt ist. Nach unten hin bildet die Umkleidung abwinkelnde Ränder aus, mit denen sie auf einer dem Gehäuse raumseitig zugeordneten Abdeckplatte mit Auslässen aufliegt bzw. befestigt ist.With such an outlet, the refrigeration unit consists of a round or approximately square casing, which forms a shoulder upwards. The shoulder forms a particularly round opening, which has a cylindrical, chimney or funnel-shaped air inlet. At the bottom, the casing forms angled edges with which it rests or is attached to a cover plate with outlets assigned to the housing on the room side.

Innerhalb der Umkeidung ist ein Kälteaggregat eingesetzt. Dieses Kälteaggregat besteht aus Rohren, insbesondere aus Wasserrohren, welche waagrecht und senkrecht zueinander verlaufen und miteinander verbunden sind. Den Rohren sind zur besseren Abgabe der Kühlung nebeneinanderliegende Lamellen zugeordnet, wobei diese Lamellen vorzugsweise aus etwa rechteckigen metallischen, dünnwandigen Platten besteht. Entsprechende Bohrungen in den Lamellen werden von den Rohren durch durchdrungen und sind durch Löt- oder Schweißpunkte fest mit den Rohren verbunden und zwar so, daß sie Zwischenräume ausbilden, durch die ein entsprechender Luftstrom streichen kann.A cooling unit is used within the casing. This refrigeration unit consists of pipes, in particular water pipes, which run horizontally and perpendicularly to one another and are connected to one another. For better delivery of the cooling, the fins are adjacent to each other, these fins preferably consisting of approximately rectangular, metallic, thin-walled plates. Corresponding bores in the fins are penetrated by the tubes and are firmly connected to the tubes by soldering or welding points, in such a way that they form gaps through which a corresponding air flow can pass.

Die Rohre des Kühlaggregates sind bevorzugt mit Leitungswasser gefüllt, wofür sie einen Anschluß an ein Leitungswassersystem besitzen.The pipes of the cooling unit are preferably filled with tap water, for which they have a connection to a tap water system.

Ferner können die Rohre erfindungsgemäß über ein Rohrsystem mit einer Wärmepumpe verbunden sein.Furthermore, according to the invention, the pipes can be connected to a heat pump via a pipe system.

Beim Strömen der Luft durch das Kühlaggregat kühlt die Luft ab, weil das im Kühlaggregat befindliche Leitungswasser gewöhnlich eine Temperatur von ca. 8° C hat. Umgekehrt wird Wärme von der Luft an das Leitungswasser abgegeben. Das so leicht erwärmte Leitungswasser fließt über einen Rücklauf zu der Wärmepumpe, gibt dort über einen Wärmetauscher die Wärme ab und fließt nun wieder abgekühlt über einen Vorlauf zum Kühlaggregat. Bei diesem Vorgang wird einerseits sehr wenig Leitungswasser verbraucht, andererseits kann die über die Wärmepumpe gewonnene Wärme weiterverwendet werden. Es ist denkbar, daß mit dieser gewonnenen Wärme sonnenabgelegene Gebäudeteile geheizt werden oder aber, daß sie zur Erwärmung von Brauchwasser verwendet wird.When the air flows through the cooling unit, the air cools down because the tap water in the cooling unit usually has a temperature of approx. 8 ° C. Conversely, heat is released from the air into the tap water. The tap water, which is so slightly heated, flows via a return line to the heat pump, releases the heat there via a heat exchanger, and then flows back down to a cooling unit via a flow line. On the one hand, very little tap water is consumed in this process, on the other hand, the heat obtained via the heat pump can be reused. It is conceivable that parts of the building located away from the sun are heated with this heat, or that it is used for heating domestic water.

Das Gehäuse des o.g. Auslasses besitzt Seitenwände, welche bevorzugt Umluftschlitze aufweisen bzw. in welche Umluftschlitze eingestanzt oder eingeformt sind. Hinter den Umluftschlitzen sind Lamellen angeordnet, welche von Hand, mechanisch oder elektronisch, hydraulisch, pneumatisch od. dgl. verstellbar sind. Sie sorgen dafür, daß der Auslaß mit Umluft versorgt und daß die jeweils beste Luftströmung erreicht wird.The housing of the above The outlet has side walls, which preferably have recirculation slots or in which recirculation slots are punched or molded. Slats are arranged behind the air vents, which are adjustable by hand, mechanically or electronically, hydraulically, pneumatically or the like. They ensure that the outlet is supplied with circulating air and that the best air flow is achieved.

Innerhalb des zylinder-, kamin- oder trichterförmigen Luftauslasses sind vorzugsweise zwei Ventilatoren nebeneinander installiert, welche einzeln schaltbar und so angeordnet sind, daß jeweils ein Ventilator eine Aggregathälfte beaufschlagt.Within the cylindrical, chimney or funnel-shaped air outlet, two fans are preferably installed side by side, which can be switched individually and are arranged such that one fan acts on one unit half.

Wird viel Kühlung benötigt, sind beide Ventilatoren in Betrieb, so daß das gesamte Kühlaggregat mit Umluft umspült wird. Es wird dadurch viel Kälte an den Raum abgegeben.If a lot of cooling is required, both fans are in operation so that the entire cooling unit is flushed with circulating air. As a result, a lot of cold is released into the room.

Wird weniger Kühlung benötigt, schaltet ein Ventilator ab, so daß nur noch ein Ventilator über der Hälfte des Kühlaggregates läuft. Dies ist ein enormer Vorteil, so daß im Falle der kleinen Luftleitung auch nur etwa die Hälfte des Kühlaggregates beaufschlagt wird, so daß der Auslaß auch bei minimaler Zuluftführung noch einwandfrei funktioniert.If less cooling is required, a fan switches off so that only one fan runs over half of the cooling unit. This is an enormous advantage, so that in the case of a small air line, only about half of the cooling unit is acted on, so that the outlet still functions perfectly even with a minimal supply of air.

Es ist jedoch auch denkbar, daß innerhalb des Lufteubkasses nur ein Ventilator, welcher beispielsweise in mehreren Stufen betrieben werden kann, installiert ist.However, it is also conceivable that only one fan, which can be operated in several stages, for example, is installed within the air lump-sum fund.

Der Auslaß, insbesondere die Ventilatoren sind über einen Raumtermostat gesteuert, so daß eine gleichmäßige Raumtemperatur erhalten werden kann. Dieser Raumthermostat kann auch mit der Wärmepumpe verbunden sein, so daß bei Stillstand der Ventilatoren auch die Zirkulation des Leitungswassers eingestellt wird.The outlet, especially the fans, are controlled by a room thermostat so that a constant room temperature can be obtained. This room thermostat can also be connected to the heat pump so that the circulation of the tap water is also set when the fans are not running.

Um eine sehr gute und schnelle und dennoch zugfreie Durchmischung der Raumluft zu gewährleisten, besitzt die o.g. Abdeckplatte spezielle, insbesondere radial, etwa sternförmig angeordnete Schlitze, denen wiederum im Gehäuseinneren speziell angeordnete Lamellen zugeordnet sind.In order to ensure a very good and quick, yet draft-free mixing of the room air, the above-mentioned cover plate has special, in particular radial, approximately star-shaped slots, which in turn are assigned to specially arranged lamellae inside the housing.

Der große Vorteil eines solchen Auslasses mit Kältesatz ist der, daß hier keine zusätzliche Energie für Kühlaggregate mit entsprechendem Kältemittel, wie beispielsweise (CKW) gebraucht wird. Gerade bei luft- und klimatechnischen Anlagen ist die Kühlung sehr energieaufwendig und teuer. Bei diesem Auslaß kann normales Leitungswasser verwendet werden. In Verbindung mit der Wärmepumpe ist dieses Gerät enorm energieeinsparend. Ein weiterer Vorteil ist, daß die Installation äußerst einfach und praktisch auch von jedem Installateur oder Heizungsfachmann vorgenommen werden kann.The great advantage of such an outlet with refrigeration unit is that no additional energy is required for cooling units with the appropriate refrigerant, such as (CHC). In air and air conditioning systems in particular, cooling is very energy-intensive and expensive. Normal tap water can be used with this outlet. In conjunction with the heat pump, this device is extremely energy-saving. Another advantage is that the installation can be carried out extremely easily and practically by any installer or heating specialist.

Ein erfindungsgemäßer Auslaß R besteht aus einem Gehäuse 1 mit Seitenwänden 2 und einer etwa quadratischen Abdeckplatte 3. Die Abdeckplatte ist mit Schlitzen 4 versehen, die im bevorzugten Ausführungsbeispiel radial, sternförmig angeordnet sind.An outlet R according to the invention consists of a housing 1 with side walls 2 and an approximately square cover plate 3. The cover plate is provided with slots 4 which, in the preferred exemplary embodiment, are arranged radially in a star shape.

Den Schlitzen 2 sind im Inneren des Gehäuses 1 Lamellen 8 angeformt oder zugeordnet, welche so gestellt sind, daß durch eine sehr gute Induktion eines von innen nach außen geführten Luftstromes eine sehr schnelle und dennoch zugfreie Raumdurchspülung erreicht wird.The slots 2 are molded or assigned in the interior of the housing 1 lamellae 8, which are set so that a very fast, yet draft-free flushing of the room is achieved by a very good induction of an air flow guided from the inside.

Andersseitig der Abdeckplatte 3 ist das Gehäuse 1 mit einer Platte 5 abgedeckt, von welcher seitlich Ränder 6 abkragen, welche die Seitenwände 2 teilweise übergreifen. Die Platte 5 ist durch Befestigungselemente 7 wie beispielsweise Nieten od. dgl., welche sowohl die Ränder 6 als auch die Seitenwände 2 durchdringen, endgültig festgelegt.On the other side of the cover plate 3, the housing 1 is covered with a plate 5, from which laterally edges 6 protrude which partially overlap the side walls 2. The plate 5 is finally fixed by fastening elements 7 such as rivets or the like, which penetrate both the edges 6 and the side walls 2.

An den Seitenwänden 2 des Gehäuses 1 sind Umluftschlitze 9 ausgespart bzw. eingearbeitet, hinter denen Lamellen 10 verstellbar angeordnet sind. Die Lamellen 10 sind so eingestellt, daß die bestmögliche gewünschte Zuluft in das Innere des Gehäuses 1 gelangen kann.On the side walls 2 of the housing 1, recirculated air slots 9 are recessed or incorporated, behind which slats 10 are arranged in an adjustable manner. The fins 10 are set so that the best possible desired supply air can get into the interior of the housing 1.

In das Gehäuse 1 ist ein Kältesatz 11 eingesetzt. Der Kältesatz 11 besteht im wesentlichen aus einer Umkleidung 12, einem Kühlaggregat 13 und zwei dem Kühlaggregat 13 zugeordneten Ventilatoren 14 und 15.A refrigeration unit 11 is inserted into the housing 1. The cooling unit 11 essentially consists of a casing 12, a cooling unit 13 and two fans 14 and 15 assigned to the cooling unit 13.

Die Umkleidung 12, welche beispielsweise quadratisch ausgebildet sein kann,besitzt Seitenteile 16, von welchen zur Abdeckplatte 3 hin Seitenstreifen 17 abkragen. Mit diesen Seitenstreifen 17 sitzt die Umkleidung 12 auf der Abdeckplatte 3.The casing 12, which may be square, for example, has side parts 16, from which side strips 17 protrude toward the cover plate 3. With these side strips 17, the casing 12 sits on the cover plate 3.

Zur Platte 5 des Gehäuses 1 hin bildet die Umkleidung 12 eine Schulter 18 aus, welche eine runde Öffnung 19 ausformt. Die Öffnung 19 ist mit einem zylindrisch geformten Lufteinlaß 20 umgeben, welchem eine Abkantung 21 angeformt ist. Mit dieser Abkantung 21 ist der Lufteinlaß 20 durch Befestigungselemente 22, wie beispielsweise Nieten, Schrauben od. dgl., an der Schulter 18 festgelegt.The casing 12 forms a shoulder 18 towards the plate 5 of the housing 1, which shoulder 18 forms a round opening 19. The opening 19 is surrounded by a cylindrically shaped air inlet 20, which is formed with a bend 21. With this bevel 21, the air inlet 20 is fixed to the shoulder 18 by fastening elements 22, such as rivets, screws or the like.

Das Kühlaggregat 13, welches sich innerhalb der Umkleidung 12 befindet, besteht im wesentlichen aus rechtwinklig einander zugeordneten und waagrecht und senkrecht miteinander verbundenen Rohren 23, wobei an diesen Rohren 23 flache, etwa rechteckige Lamellen 24 angebracht sind, so daß diese Lamellen 24 bevorzugt senkrecht zur Abdeckplatte 3 liegen.The cooling unit 13, which is located within the casing 12, consists essentially of at right angles to each other and horizontally and vertically interconnected tubes 23, 23 flat, approximately rectangular fins 24 are attached to these tubes, so that these fins 24 preferably perpendicular to Cover plate 3 are.

Diese Lamellen 24 sind sehr dicht hintereinander angeordnet und gewährleisten so durch die Bildung einer großen Oberfläche einen sehr guten Temperaturaustausch.These fins 24 are arranged very closely one behind the other and thus ensure a very good temperature exchange by forming a large surface.

Die Rohre 23 besitzen gemäß Figur 3 einen nicht näher dargestellten Anschluß an einen Zulauf 25 und an einen Rücklauf 26.According to FIG. 3, the tubes 23 have a connection (not shown in more detail) to an inlet 25 and to a return 26.

Innerhalb des Lufteinlasses 20 sind zwei Ventilatoren 14 und 15 installiert, welche separat schaltbar sind. Die Ventilatoren 14 und 15 bewirken durch ihren Betrieb, daß durch die Umluftschlitze 9 Luft in das Gehäuse 1 und von da in den Lufteinlaß 20 strömt. Von hier wird die Luft von den Ventilatoren 14 und 15 durch die Lamellen 24 über die Rohre 23 geblasen, wobei ein Wärmeaustausch stattfindet. Dabei wird die durch Wasser herbeigeführte kühlere Temperatur an den Luftstrom übertragen und gleichzeitig vom Luftstrom an das Wasser Wärme abgegeben. Das so in den Rohren 23 erwärmte Wasser fließt über den Rücklauf 26 in eine Wärmepumpe 27. Hier wird dem Wasser wieder die Wärme entzogen, es kühlt ab auf etwa Leitungswassertemperatur und fließt über den Vorlauf 25 wieder zum Kühlaggregat. Die von der Wärmepumpe entzogene Wärme kann beispielsweise zur Heizung von sonnenabgelegenen Gebäudeteile oder für die Erwärmung von Brauchwasser verwendet werden.Two fans 14 and 15 are installed within the air inlet 20 and can be switched separately. The fans 14 and 15, through their operation, cause air to flow through the air slots 9 into the housing 1 and from there into the air inlet 20. From here, the air from the fans 14 and 15 is blown through the fins 24 via the tubes 23, with a heat exchange taking place. The cooler temperature caused by water is transferred to the air flow and at the same time heat is released from the air flow to the water. The water thus heated in the tubes 23 flows via the return 26 into a heat pump 27. Here, the heat is extracted from the water again, it cools down to about the tap water temperature and flows via the feed 25 back to the cooling unit. The heat extracted by the heat pump can be used, for example, to heat parts of the building away from the sun or to heat domestic water.

Der gesamte Auslaß R mit dem Kältesatz 11 wird über einen Raumthermostat 28 gesteuert. Dabei regelt der Raumthermostator 28 vorwiegend den Betrieb der Ventilatoren 14 und 15.The entire outlet R with the refrigeration unit 11 is controlled by a room thermostat 28. The room thermostat 28 mainly controls the operation of the fans 14 and 15.

Ist eine starke Raumkühlung erforderlich, schaltet der Raumthermostat 28 beide Ventilatoren 14 und 15 auf Betrieb. Bei nur geringer Abkühlung wird nur ein, beispielsweise der Ventilator 14 auf Betrieb geschaltet, so daß nur eine Hälfte des Kühlaggregates 13 mit Luft beaufschlagt wird.If strong room cooling is required, the room thermostat 28 switches both fans 14 and 15 to operation. With only slight cooling, only one, for example the fan 14, is switched to operation, so that only half of the cooling unit 13 is acted upon by air.

Ist überhaupt keine Kühlung erforderlich, setzt der Raumthermostat 28 beide Ventilatoren 14 und 15 außer Betrieb. In diesem Fall wird vom Raumthermostat 28 auch die Wärmepumpe 27 abgeschaltet.

If no cooling is required at all, the room thermostat 28 disables both fans 14 and 15. In this case, the room thermostat 28 also turns off the heat pump 27.
