However, the cool air often accumulates above the sail, reducing the cooling effect. When heated, the heat accumulates under the sail, limiting the effectiveness of passive sails.

Description

Die Erfindung betrifft ein Heiz- und Kühlsegel, umfassend mindestens eine Trägerplatte und damit wärmeleitend verbundene Kanäle, die mit einem Fluid durchströmbar sind, sowie mindestens einen Ventilator mit einer Luftaustrittsfläche.The invention relates to a heating and cooling sail, comprising at least one support plate and channels connected to it in a heat-conducting manner, through which a fluid can flow, and at least one fan with an air outlet surface.

Stand der TechnikState of the art

Kühlsegel sind bereits seit geraumer Zeit aus dem Stand der Technik bekannt und werden dazu genutzt, Raumwärme abzuführen. Dies erfolgt über die mit der Trägerplatte wärmeleitend verbundenen Rohre, die typischerweise mit Wasser als Wärmeträgermedium durchströmt werden, wobei die warme aufsteigende Raumluft ihre Wärme an das kühle Wasser abgibt.Cooling sails have been known from the state of the art for some time and are used to dissipate room heat. This is done via the pipes connected to the support plate in a heat-conducting manner, through which water typically flows as a heat transfer medium, with the warm rising room air giving off its heat to the cool water.

Oftmals werden Kühlsegel mit Lüftungsanlagen kombiniert, da im Kühlfall eine Begrenzung der Raumfeuchte zur Vermeidung von Kondensation notwendig ist. Darüber hinaus wird über die Lüftungsanlagen auch das Anströmen der Kühlsegel beeinflusst. Dabei können die Lüftungsanlagen beispielsweise Quellauslässe am Boden, an der Wand oder an der Decke umfassen.Cooling sails are often combined with ventilation systems because, in the case of cooling, it is necessary to limit the room humidity to avoid condensation. In addition, the airflow to the cooling sails is also influenced by the ventilation systems. The ventilation systems can, for example, include source outlets on the floor, on the wall or on the ceiling.

Allerdings ist die Verwendung eines Heiz- und Kühlsegels auch in Räumen ohne Lüftungsanlagen möglich, insbesondere wenn Kühlsegel nachträglich in Räumen installiert werden sollen, die nicht über eine Lüftungsanlage verfügen und die Nachrüstung einer solchen aus Kostengründen nicht in Frage kommt. Die notwendige Frischluftzufuhr muss dann durch klassische Fensterlüftung erfolgen.However, the use of a heating and cooling sail is also possible in rooms without ventilation systems, especially if cooling sails are to be subsequently installed in rooms that do not have a ventilation system and retrofitting one is out of the question for cost reasons. The necessary supply of fresh air must then be provided through classic window ventilation.

Bei Heiz- und Kühlsegeln ohne angeschlossene Lüftungsanlage handelt es sich um ein System, das rein passiv arbeitet. Im Kühlfall steigt warme Raumluft nach oben und gelangt an das Segel, wo die Wärme an das in den Kanälen geführte kühle Fluid abgegeben wird. Hier staut sich jedoch die kühle Luft oftmals oberhalb des Segels, so dass der Kühleffekt vermindert wird. Im Heizfall staut sich die Wärme unter dem Segel, so dass die Wirksamkeit passiver Segel eingeschränkt ist.Heating and cooling sails without a connected ventilation system are a system that works purely passively. When cooling occurs, warm room air rises and reaches the sail, where the heat is transferred to the cool fluid carried in the channels. However, the cool air often accumulates above the sail, reducing the cooling effect. When heated, the heat accumulates under the sail, limiting the effectiveness of passive sails.

Um den Kühlungseffekt bei einem reinen passiven System zu unterstützen, ist es möglich, einen Ventilator auf dem Kühlsegel vorzusehen. Hierdurch erhält man ein aktives Umluftsystem. Je nach Anordnung des Ventilators profitiert davon entweder der Heiz- oder der Kühlfall.To support the cooling effect in a purely passive system, it is possible to provide a fan on the cooling sail. This creates an active air circulation system. Depending on the arrangement of the fan, either the heating or the cooling case benefits.

Aus dem Dokument EP 0 377 756 A1 ist eine Kühlvorrichtung zum lokalen Kühlen eines Arbeitsplatzes bekannt. Die bekannte Vorrichtung verfügt über ein Gehäuse mit einer Frontwand und einer Rückwand, wobei ein Innenraum des Gehäuses mit Zuluft aus einer Klimaanlage gespeist wird. Im Innenraum des Gehäuses sind Peltier-Elemente zum Kühlen der Zuluft angeordnet.From the document EP 0 377 756 A1 a cooling device for locally cooling a workplace is known. The known device has a housing with a front wall and a rear wall, an interior of the housing being fed with supply air from an air conditioning system. Peltier elements are arranged in the interior of the housing to cool the supply air.

Das Dokument WO 2011/091886 A1 beschreibt ein Deckensegel mit Luftauslass, wobei die Zuluft ausgehend von ihrer Einleitung in den Luftauslass bis hin zum Austritt desselben um etwa 180° umgelenkt wird. Ein Überströmen der Trägerplatte erfolgt mittels Düsen.The document WO 2011/091886 A1 describes a ceiling sail with an air outlet, whereby the supply air is deflected by approximately 180° from its introduction into the air outlet to its exit. Flow over the carrier plate occurs via nozzles.

AufgabeTask

Es ist Aufgabe der vorliegenden Erfindung, ein Heiz- und Kühlsegel der eingangs genannten Art so weiterzuentwickeln, dass es sich hinsichtlich seiner Wirtschaftlichkeit und seiner akustischen Eigenschaften auszeichnet und dass es sowohl im Heiz- als auch im Kühlfall gleichermaßen vom Einsatz des Ventilators profitiert.It is the object of the present invention to further develop a heating and cooling sail of the type mentioned in such a way that it is distinguished in terms of its economic efficiency and its acoustic properties and that it benefits equally from the use of the fan in both heating and cooling cases.

LösungSolution

Ausgehend von dem zu Anfang beschriebenen Heiz- und Kühlsegel wird die vorstehende Aufgabe durch ein Segel nach Anspruch 1 gelöst.Starting from the heating and cooling sail described at the beginning, the above task is solved by a sail according to claim 1.

Gemäß der vorliegenden Erfindung liegt demnach eine Aufteilung des die Luftaustrittsfläche des Ventilators verlassenen Gesamtvolumenstroms vor, was im Kühlfall den Effekt hat, dass die sich stauende kühle Luft oberhalb der Trägerplatte aktiv in den Raum bewegt wird, wodurch der Kühleffekt deutlich gesteigert werden kann. Gleichzeitig wird der Teilvolumenstrom, der unterhalb der Trägerplatte verläuft, direkt in den Raum geführt, wodurch aufgrund der Luftbewegung der Eindruck einer Frischluftzufuhr entsteht. Darüber hinaus ist allein die Tatsache vorteilhaft, dass beide Seiten der Trägerplatte aktiv überströmt werden, da hierdurch per se eine erhöhte Wärmeübertragung stattfindet und die Leistung des Heiz- und Kühlsegels somit gesteigert wird.According to the present invention, there is a division of the total volume flow leaving the air outlet surface of the fan, which in the case of cooling has the effect that the cool air accumulating above the support plate is actively moved into the room, whereby the cooling effect can be significantly increased. At the same time, the partial volume flow that runs below the support plate is led directly into the room, which creates the impression of a fresh air supply due to the air movement. In addition, the mere fact that both sides of the carrier plate are actively flowed over is advantageous, as this per se increases heat transfer and thus increases the performance of the heating and cooling sail.

Dass das Leitelement in einem Bereich "vor" der Luftaustrittsfläche angeordnet ist, ist so zu verstehen, dass das Leitelement außerhalb des Ventilators positioniert ist. Anders ausgedrückt befindet sich das Leitelement in Strömungsrichtung betrachtet hinter der Luftaustrittsfläche, so dass die den Ventilator verlassende Luft zunächst die Luftaustrittsfläche passiert, bevor sie an das Leitelement gelangt.The fact that the guide element is arranged in an area “in front of” the air outlet surface is to be understood as meaning that the guide element is positioned outside the fan. In other words, the guide element is located behind the air outlet surface when viewed in the direction of flow, so that the air leaving the fan first passes the air outlet surface before it reaches the guide element.

Im Heizfall, also für den Fall, dass die Raumtemperatur geringer ist als die des "Kühlmediums" in den Kanälen, bewirkt die Aufteilung des den Ventilator verlassenen Gesamtvolumenstroms, dass die sich unterhalb der Trägerplatte stauende warme Luft aktiv wieder in den Raum gebracht wird, was den Heizeffekt verstärkt und die Eindringtiefe der Warmluft in Richtung auf den Boden des Raums erhöht. Die Bildung von einer Temperaturschicht wird auch ohne die Anordnung von Düsen verhindert und es entsteht eine gleichmäßig durchmischte Raumluft.In the case of heating, i.e. in the event that the room temperature is lower than that of the "cooling medium" in the ducts, the division of the total volume flow leaving the fan causes the warm air accumulating below the support plate to be actively brought back into the room, which strengthens the heating effect and increases the penetration depth of the warm air towards the floor of the room. The formation of a temperature layer is prevented even without the arrangement of nozzles and an evenly mixed room air is created.

Bei dem Ventilator handelt es sich vorteilhafterweise um einen frei blasenden Ventilator ohne Gehäuse, so dass die Bauhöhe des erfindungsgemäßen Heiz- und Kühlsegels klein bleibt. Da der Ventilator nicht an eine Primärluftversorgung angeschlossen ist, handelt es sich um ein reines Umluftsystem, das jedoch aktiv betrieben wird. Durch die Anordnung des Leitelements und die dadurch hervorgerufene Unterteilung des den Ventilator verlassenen Volumenstroms entsteht ein Heiz- und Kühlsegel mit variablen Einsatzmöglichkeiten, das sich ferner durch geringen Stromverbrauch und gute schalltechnische Eigenschaften auszeichnet, da Ventilatoren mit geringer Druckerhöhung eingesetzt werden können.The fan is advantageously a free-blowing fan without a housing, so that the overall height of the heating and cooling sail according to the invention remains small. Since the fan is not connected to a primary air supply, it is a pure recirculation system, but is actively operated. The arrangement of the guide element and the resulting subdivision of the volume flow leaving the fan creates a heating and cooling sail with variable application options, which is also characterized by low power consumption and good acoustic properties, since fans with a low pressure increase can be used.

Es versteht sich von selbst, dass in Abhängigkeit von der Breite des Heiz- und Kühlsegels mehrere Ventilatoren nebeneinander angeordnet werden können, um die vormals beschriebenen positiven Strömungsverhältnisse über die gesamte Breite des Segels zu erhalten.It goes without saying that, depending on the width of the heating and cooling sail, several fans can be arranged next to each other in order to maintain the previously described positive flow conditions over the entire width of the sail.

Andersherum ist es auch denkbar, dass lediglich ein Ventilator vorgesehen wird, der eine oder mehrere Trägerplatten anströmt. Hierzu wird der Ventilator mit Kanälen ausgestattet, die ausgehend von dem Ventilator zu dem oder den jeweiligen Leitelementen der einzelnen Trägerplatten führen. Somit wird die Luftaustrittsfläche des Ventilators durch die einzelnen Luftaustrittsflächen der vor dem Leitelement endenden Kanäle gebildet. (Anregung von Herrn Makulla)Conversely, it is also conceivable that only one fan is provided, which flows against one or more carrier plates. For this purpose, the fan is equipped with channels which, starting from the fan, lead to the respective guide element or elements of the individual carrier plates. The air outlet surface of the fan is thus formed by the individual air outlet surfaces of the channels ending in front of the guide element. (Suggestion from Mr Makulla)

Das Leitelement kann als einfaches Blech ausgebildet sein oder beispielsweise als sogenanntes Schöpfblech, wobei es mit der Trägerplatte verbunden sein kann. Eine Verbindung von Leitelement und Trägerplatte kann durch Kleben, Schweißen, Löten, Schrauben oder sonstige Weise erfolgen. Alternativ kann das Leitelement auch mit Hilfe anderer Mittel positioniert sein und kann einen Abstand zu der Trägerplatte aufweisen. Die Breite des Leitelements sollte mindestens oder genau der Breite des Luftaustrittsquerschnitts des Ventilators bzw. aller Ventilatoren entsprechen. Das Leitelement kann auch aus Kunststoff oder anderen Materialien gefertigt sein.The guide element can be designed as a simple sheet metal or, for example, as a so-called scoop plate, whereby it can be connected to the carrier plate. The guide element and carrier plate can be connected by gluing, welding, soldering, screwing or in another way. Alternatively, the guide element can also be positioned using other means and can be at a distance from the carrier plate. The width of the guide element should be at least or exactly the width of the air outlet cross section of the fan or all fans. The guide element can also be made of plastic or other materials.

Mit der Anordnung des Leitelements kann in Bezug auf die Aufteilung des die Luftaustrittsfläche verlassenden Gesamtvolumenstroms insofern Einfluss genommen werden, als dass die Aufteilung durch die Höhe beeinflusst wird, bis zu der das Leitelement in Bezug auf die Höhe der Luftaustrittsfläche ragt. Führt das Leitelement genau bis zur Hälfte der Höhe der Luftaustrittsfläche, so liegt - gleiche Widerstände in beiden Strömungswegen unterstellt - eine genaue Teilung des Gesamtvolumenstroms in zwei gleiche Teilvolumenströme vor. Andernfalls sind die Teilvolumenströme unterschiedlich groß, wobei die Widerstände in den jeweiligen Strömungswegen ebenfalls einen Einfluss auf die Aufteilung besitzen.With the arrangement of the guide element, the distribution of the total volume flow leaving the air outlet surface can be influenced in such a way that the distribution is influenced by the height up to which the guide element protrudes in relation to the height of the air outlet surface. If the guide element extends exactly to half the height of the air outlet surface, then - assuming equal resistance in both flow paths - there is an exact division of the total volume flow into two equal partial volume flows. Otherwise, the partial volume flows are of different sizes, with the resistances in the respective flow paths also having an influence on the distribution.

In Bezug auf die erfindungsgemäße Luftführung ist es ferner vorteilhaft, wenn der Abstand zwischen einem der Luftaustrittsfläche zugewandten Rand des Leitelements und der Luftaustrittsfläche so klein wie möglich gewählt ist. Dementsprechend ist es denkbar, dass das Leitelement direkt an die Luftaustrittsfläche angrenzt und somit ein Abstand von 0 mm vorliegt. In diesem Fall liegt eine sofortige Trennung des Gesamtvolumenstroms vor und der unter die Trägerplatte strömende Teilvolumenstrom wird optimal geführt. Ist der Abstand zu groß gewählt, besteht die Gefahr, dass der zur Strömung unterhalb der Trägerplatte vorgesehene Teilvolumenstrom nicht in ausreichendem Maß geführt wird und nur teilweise unter die Trägerplatte gelangt. Um den positiven Effekt der Luftführung nicht zu gefährden, sollte der Abstand kleiner oder gleich 200 mm betragen, vorteilhafterweise kleiner 100 mm, besser jedoch kleiner 50 mm, weiter vorteilhafterweise kleiner 20 mm.With regard to the air duct according to the invention, it is also advantageous if the distance between an edge of the guide element facing the air outlet surface and the air outlet surface is chosen to be as small as possible. Accordingly, it is conceivable that the guide element is directly adjacent to the air outlet surface and therefore there is a distance of 0 mm. In this case, there is an immediate separation of the total volume flow and the partial volume flow flowing under the carrier plate is optimally guided. If the distance is chosen to be too large, there is a risk that the partial volume flow intended for flow below the carrier plate will not be guided to a sufficient extent and will only partially reach under the carrier plate. In order not to jeopardize the positive effect of the air guidance, the distance should be less than or equal to 200 mm, advantageously less than 100 mm, but better less than 50 mm, more advantageously less than 20 mm.

Vorteilhafterweise ist der Ventilator bzw. die Ventilatoren mit einer Aufstellfläche auf der Trägerplatte angeordnet, so dass sich die Luftaustrittsfläche des Ventilators bzw. der Ventilatoren insgesamt oberhalb der Trägerplatte befindet. Typischerweise ist die Trägerplatte an sich ausreichend stabil sowie auch ausreichend stabil mit der Raumdecke verbunden, insbesondere abgehängt, so dass der Ventilator auf der Trägerplatte zu liegen kommen kann, ohne separat an der Raumdecke befestigt werden zu müssen. Um jedoch eine Schallemission seitens des im Betrieb befindlichen Ventilators zu vermeiden, kann es vorteilhaft sein, den Ventilator an der Trägerplatte zu befestigen.Advantageously, the fan or fans is arranged with a support surface on the support plate, so that the air outlet surface of the fan or fans is located overall above the support plate. Typically, the carrier plate itself is sufficiently stable and also sufficiently stable connected to the ceiling, in particular suspended, so that the fan can come to rest on the carrier plate without having to be separately attached to the ceiling. However, in order to avoid noise emissions from the fan in operation, it may be advantageous to attach the fan to the support plate.

Um ein Strömen des unterhalb des Leitelements aus dem Luftaustrittsquerschnitt austretenden Teilvolumenstroms auf die Unterseite der Trägerplatte zu gewährleisten, muss die Trägerplatte zumindest teilweise, vorzugsweise in einem Bereich einer Projektion des Leitelements, perforiert sein bzw. eine Öffnung besitzen. Auf diese Weise gelangt der unterhalb des Leitelements geführte Teilvolumenstrom über die Perforationen bzw. die Öffnung auf die Unterseite der Trägerplatte und strömt entlang derselben.In order to ensure that the partial volume flow emerging from the air outlet cross section below the guide element flows to the underside of the carrier plate, the carrier plate must be at least partially perforated or have an opening, preferably in an area of a projection of the guide element. In this way, the partial volume flow guided below the guide element reaches the underside of the carrier plate via the perforations or the opening and flows along it.

Bezüglich des Winkels zwischen dem Leitelement und der Trägerplatte kann es sinnvoll sein, wenn das Leitelement im Hinblick auf den Winkel, den es mit der Luftaustrittsfläche des Ventilators einschließt, einstellbar ist. Mit der individuellen Einstellung des Winkels kann der gesamte Volumenstrom beliebig in verschiedene Teilvolumenströme unterteilt werden, wodurch sich unterschiedliche Kühleffekte bzw. Heizeffekte ergeben. Die Einstellung kann durch ein feststellbares oder motorisch betriebenes Haltelement erfolgen, so dass eine individuelle Anpassung des Segels an eine Raum- oder Lastsituation möglich ist.With regard to the angle between the guide element and the support plate, it can make sense if the guide element is adjustable with regard to the angle that it forms with the air outlet surface of the fan. With the individual adjustment of the angle, the entire volume flow can be divided into different partial volume flows, resulting in different cooling effects or heating effects. The adjustment can be done using a lockable or motor-operated holding element, so that the sail can be individually adapted to a space or load situation.

Des Weiteren kann vorgesehen sein, dass die Trägerplatte Perforationen oder Löcher besitzt, die vorzugsweise einen freien Querschnitt von etwa 10 % bis 30 %der perforierten bzw. gelochten Gesamtfläche definieren. Dabei kann sowohl die gesamte Sichtfläche oder nur ein Teil derselben gelocht sein. Ferner kann es im Hinblick auf die Akustik sinnvoll oder hilfreich sein, schallschluckende Elemente auf oder oberhalb der Trägerplatte vorzusehen. Auf diese Weise lassen sich erhöhte Anforderungen bezüglich des Schallschutzes verwirklichen. Hierbei ist konstruktiv sicherzustellen, dass ein Wärmeübergang von der Oberseite der Trägerplatte zur Umgebungsluft möglich ist.Furthermore, it can be provided that the carrier plate has perforations or holes, which preferably define a free cross section of approximately 10% to 30% of the perforated or holed total area. The entire visible surface or only part of it can be perforated. Furthermore, with regard to acoustics, it can be useful or helpful to provide sound-absorbing elements on or above the support plate. In this way, increased requirements regarding sound insulation can be met. Here It must be structurally ensured that heat transfer from the top of the carrier plate to the ambient air is possible.

Eine besonders bevorzugte Ausführungsform der Erfindung sieht vor, dass es sich bei dem mindestens einen Ventilator um einen Ventilator mit geringer Druckerhöhung handelt, der sich dadurch auszeichnet, dass er bei sehr geringer Geräuschentwicklung einen hohen Volumenstrom fördert. Auch ist der Stromverbrauch sehr niedrig. Beispielsweise kann ein Querstromventilator verwendet werden. Ein weiterer Vorteil, der sich aus dem vorgenannten Merkmal ergibt, ist die sehr niedrige mögliche Bauhöhe, die das erfindungsgemäße Heiz- und Kühlsegel aufweist. Die Bauhöhe des Ventilators sollte im Bereich zwischen 20 und 80 mm liegen, woraus sich eine gesamte Bauhöhe des Kühlsegels in quasi gleicher Größe ergibt.A particularly preferred embodiment of the invention provides that the at least one fan is a fan with a low pressure increase, which is characterized in that it promotes a high volume flow with very little noise. The power consumption is also very low. For example, a cross-flow fan can be used. Another advantage that results from the aforementioned feature is the very low possible overall height that the heating and cooling sail according to the invention has. The overall height of the fan should be between 20 and 80 mm, which results in an overall overall height of the cooling sail of virtually the same size.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist der mindestens eine Ventilator mit einer Drehzahlregelung ausgestattet. Hierdurch lässt sich die Kühl- bzw. Heizleistung des Heiz- und Kühlsegels variieren, was im Hinblick auf die individuelle Einstellbarkeit durch den Nutzer und damit die Behaglichkeit zweckmäßig ist.According to an advantageous embodiment of the invention, the at least one fan is equipped with a speed control. This allows the cooling or heating output of the heating and cooling sail to be varied, which is useful in terms of individual adjustability by the user and thus comfort.

Wird auf der Trägerplatte zusätzlich zu den Kanälen für das Wärmeträgerfluid mindestens ein Kühlregister angeordnet, so wird eine Erhöhung der Kühlleistung ermöglicht und das erfindungsgemäße Kühlsegel kann auch in Räumen mit hohen Kühllasten eingesetzt werden.If at least one cooling register is arranged on the carrier plate in addition to the channels for the heat transfer fluid, an increase in the cooling capacity is made possible and the cooling sail according to the invention can also be used in rooms with high cooling loads.

Schließlich sei angemerkt, dass die verschiedenen Merkmale der Unteransprüche je einzeln für sich oder zu mehreren in beliebigen Kombinationen bei Varianten der Erfindung verwirklicht sein können.Finally, it should be noted that the various features of the subclaims can be implemented individually or in groups in any combination in variants of the invention.

Ausführungsbeispiel:Example:

Die vorstehend beschriebene Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert, die in den Figuren 1 bis 3 gezeigt sind.The invention described above is explained in more detail below using exemplary embodiments which are shown in the Figures 1 to 3 are shown.

Es zeigt:

Figur 1:
einen Vertikalschnitt durch ein erfindungsgemäßes Heiz- und Kühlsegel und
Figuren 2 und 3:
jeweils einen Vertikalschnitt durch alternativ ausgebildete erfindungsgemäße Heiz- und Kühlsegel.
It shows:
Figure 1:
a vertical section through a heating and cooling sail according to the invention and
Figures 2 and 3:
each a vertical section through alternatively designed heating and cooling sails according to the invention.

In der Figur 1 ist ein erfindungsgemäßes Heiz- und Kühlsegel 1 gezeigt, das sich aus einer Trägerplatte 2 mit einer Länge L und einer Breite sowie einem auf der Trägerplatte 2 angeordneten Ventilator 3 zusammensetzt. Da ein Vertikalschnitt dargestellt ist, ist die Breite der Trägerplatte 2 nicht erkennbar. Typischerweise variieren Heiz- und Kühlsegel bezüglich ihrer Breite zwischen 0,6 m bis 1,2 m. Andere Breiten sind jedoch selbstverständlich denkbar. Auch die Länge L der Trägerplatte 2 ist in der Figur 1 lediglich angedeutet, da das Heiz- und Kühlsegel 1 nicht in seiner vollständigen Länge L abgebildet ist. Die Länge von Heiz- und Kühlsegeln ist ebenfalls individuell und kann zwischen 1 m bis 4 m betragen. Wie aus dem Stand der Technik bekannt, ist die Trägerplatte 2 mit mäanderförmig verlaufenden Kanälen 4 versehen, in denen Kühlflüssigkeit, wie beispielsweise Wasser, in einem Kreislauf geführt wird. Die Trägerplatte 2 und die Kanäle 4 sind wärmeleitend miteinander verbunden.In the Figure 1 A heating and cooling sail 1 according to the invention is shown, which is composed of a carrier plate 2 with a length L and a width and a fan 3 arranged on the carrier plate 2. Since a vertical section is shown, the width of the carrier plate 2 cannot be seen. Typically, heating and cooling sails vary in width between 0.6 m and 1.2 m. However, other widths are of course conceivable. The length L of the carrier plate 2 is also in the Figure 1 only indicated, since the heating and cooling sail 1 is not shown in its full length L. The length of heating and cooling sails is also individual and can be between 1 m and 4 m. As is known from the prior art, the carrier plate 2 is provided with meandering channels 4 in which cooling liquid, such as water, is circulated. The carrier plate 2 and the channels 4 are connected to one another in a heat-conducting manner.

Bei dem Ventilator 3 handelt es sich um einen frei blasenden Ventilator 3, der kein Gehäuse besitzt und der Raumluft ansaugt. Dementsprechend ist er nicht mit einer lüftungstechnischen Anlage verbunden, so dass das erfindungsgemäße Heiz- und Kühlsegel 1 einen aktiven Umluftbetrieb erzeugt. Der Ventilator 3 ist mit einer Aufstellfläche 5 auf der Trägerplatte 2 angeordnet und mit dieser über nicht in der Figur 1 dargestellte Befestigungsmittel verbunden. Die Befestigung der Trägerplatte 2 an einer nicht in der Figur gezeigten Raumdecke erfolgt wie im Stand der Technik üblich durch Abhängung und ist in der Figur 1 ebenfalls nicht dargestellt. Gemäß der Figur 1 ist der Ventilator 3 an einem rechten Ende der Trägerplatte 2, also an einer kurzen Seite, angeordnet, wobei die Trägerplatte 2 entlang dieser kurzen Seite eine Aufkantung 6 besitzt.The fan 3 is a free-blowing fan 3 that has no housing and sucks in room air. Accordingly, it is not connected to a ventilation system, so that the heating and cooling sail 1 according to the invention generates an active recirculation mode. The fan 3 is arranged with a support surface 5 on the support plate 2 and is not in contact with it Figure 1 Fasteners shown connected. The support plate 2 is attached to a ceiling (not shown in the figure) by suspension, as is usual in the prior art, and is in the Figure 1 also not shown. According to the Figure 1 the fan 3 is arranged at a right end of the support plate 2, i.e. on a short side, the support plate 2 having an upstand 6 along this short side.

Der Ventilator 3 weist eine Luftaustrittsfläche 7 auf, aus der zuvor angesaugte Raumluft wieder ausströmt. In einem Bereich 8 vor der Luftaustrittsfläche 7 des Ventilators 3 ist ein Leitelement 9 angeordnet, das quer zu der Luftaustrittsfläche 7 verläuft und einen Winkel α von etwa 80° mit der Luftaustrittsfläche 7 einschließt. Dementsprechend beträgt ein Winkel β zwischen der Trägerplatte 2 und dem Leitelement 9 20°. Ein Abstand a zwischen einem dem Ventilator 3 zugewandten Rand 10 des Leitelements 9 und der Luftaustrittsfläche 7 des Ventilators 3 beträgt 20 mm. Das Leitelement 9 ist an seinem dem Ventilator 3 abgewandten Rand 10' beispielsweise über eine Schweißnaht fest mit der Trägerplatte 2 verbunden und somit nicht im Hinblick auf die vorgenannten Winkel α und β einstellbar.The fan 3 has an air outlet surface 7 from which previously sucked room air flows out again. In an area 8 in front of the air outlet surface 7 of the fan 3, a guide element 9 is arranged, which runs transversely to the air outlet surface 7 and forms an angle α of approximately 80 ° with the air outlet surface 7. Accordingly, an angle β between the carrier plate 2 and the guide element 9 is 20°. A distance a between an edge 10 of the guide element 9 facing the fan 3 and the air outlet surface 7 of the fan 3 is 20 mm. The guide element 9 is firmly connected to the support plate 2 at its edge 10 'facing away from the fan 3, for example via a weld seam, and is therefore not adjustable with regard to the aforementioned angles α and β.

Die Anordnung des Leitelements 9 bewirkt, dass ein die Luftaustrittsfläche 7 des Ventilators 3 verlassener Volumenstrom in zwei Teilvolumenströme unterteilt wird, die in der Figur mittels zwei Pfeilen 11, 12 angedeutet sind, wobei ein erster, oberer Teilvolumenstrom (Pfeil 11) oberhalb der Trägerplatte 2 strömt und ein zweiter, unterer Teilvolumenstrom (Pfeil 12) unterhalb der Trägerplatte 2 strömt. Hierdurch werden beide Seiten der Trägerplatte 2 aktiv belüftet, wodurch eine Wärmeübertragung zwecks Kühlen oder Heizen optimiert wird. Beispielsweise wird im Kühlfall der obere Teilvolumenstrom (Pfeil 11) entlang der kühles Fluid enthaltenden Kanäle 4 geführt, wodurch die Wärme des oberen Teilvolumenstroms (Pfeil 11) an das Kühlmittel abgegeben wird. Gleichzeitig wird sich unterhalb der Trägerplatte 2 stauende warme Raumluft mittels des unteren Teilvolumenstroms (Pfeil 12) wieder in den Raum R eingebracht. Die Teilvolumenströme (Pfeile 11, 12) sind im vorliegenden Fall nicht gleich groß, da das Leitelement 9 bis zu einer Höhe H der Luftaustrittsfläche 7 reicht, die größer ist als die halbe Höhe der Luftaustrittsfläche 7. Dementsprechend ist der untere Teilvolumenstrom (Pfeil 12) etwas größer als der obere Teilvolumenstrom (Pfeil 11).The arrangement of the guide element 9 causes a volume flow leaving the air outlet surface 7 of the fan 3 to be divided into two partial volume flows, which are indicated in the figure by two arrows 11, 12, with a first, upper partial volume flow (arrow 11) flows above the carrier plate 2 and a second, lower partial volume flow (arrow 12) flows below the carrier plate 2. As a result, both sides of the carrier plate 2 are actively ventilated, thereby optimizing heat transfer for cooling or heating. For example, in the case of cooling, the upper partial volume flow (arrow 11) is guided along the channels 4 containing cool fluid, whereby the heat of the upper partial volume flow (arrow 11) is released to the coolant. At the same time, warm room air accumulating below the carrier plate 2 is introduced back into the room R by means of the lower partial volume flow (arrow 12). The partial volume flows (arrows 11, 12) are not the same size in the present case, since the guide element 9 extends up to a height H of the air outlet surface 7, which is greater than half the height of the air outlet surface 7. Accordingly, the lower partial volume flow (arrow 12) slightly larger than the upper partial volume flow (arrow 11).

Um zu gewährleisten, dass der zweite, untere Teilvolumenstrom (Pfeil 12) unterhalb die Trägerplatte 2 gelangen kann, ist die Trägerplatte 2 in einem Bereich einer Projektion P des Leitelements 9 perforiert. Alternativ kann auch die Trägerplatte insgesamt mit einer Perforation versehen sein.In order to ensure that the second, lower partial volume flow (arrow 12) can reach below the carrier plate 2, the carrier plate 2 is perforated in an area of a projection P of the guide element 9. Alternatively, the carrier plate as a whole can also be provided with a perforation.

Da es sich bei der Figur 1 um einen Vertikalschnitt handelt, ist lediglich ein Ventilator 3 erkennbar. Tatsächlich befinden sich jedoch drei Ventilatoren 3 nebeneinander, d. h. in Richtung senkrecht zu der Zeichenebene hintereinander. Dementsprechend weist sowohl die Trägerplatte 2 als auch das Leitelement 9 eine Breite auf, die mindestens der Breite der drei nebeneinander befindlichen Ventilatoren 3 entspricht.Since it is at the Figure 1 It is a vertical section, only a fan 3 can be seen. In fact, however, there are three fans 3 next to each other, ie one behind the other in the direction perpendicular to the plane of the drawing. Accordingly, both the carrier plate 2 and the guide element 9 have a width that corresponds at least to the width of the three fans 3 located next to one another.

Das in der Figur 2 abgebildete Heiz- und Kühlsegel 1' weist zu dem Heiz- und Kühlsegel 1 aus Figur 1 den Unterschied auf, dass oberhalb der Trägerplatte 2 eine schallschluckendes Element 13 in Form einer Akustikmatte angeordnet ist, so dass höhere Anforderungen an den Schallschutz erreichbar sind. Die Akustikmatte befindet sich in einem Abstand a' zu der Trägerplatte 2 und kann beispielsweise an einer nicht dargestellten Raumdecke befestigt sein. Alternativ können auch Akustik-Elemente unmittelbar auf der Trägerplatte 2 angeordnet werden, wobei diese vorteilhafterweise nur im Bereich außerhalb der Kanäle 4 angeordnet werden.That in the Figure 2 The heating and cooling sail 1 'shown points to the heating and cooling sail 1 Figure 1 The difference is that a sound-absorbing element 13 in the form of an acoustic mat is arranged above the support plate 2, so that higher demands on sound insulation can be achieved. The acoustic mat is located at a distance a' from the carrier plate 2 and can, for example, be attached to a ceiling, not shown. Alternatively, acoustic elements can also be arranged directly on the carrier plate 2, whereby these are advantageously only arranged in the area outside the channels 4.

Das Leitelement 9' gemäß der Figur 2 ist nicht fest mit der Trägerplatte 2 verbunden und hinsichtlich des Winkels β einstellbar. Hierdurch kann die Ausrichtung der Teilvolumenströme (Pfeile 11, 12) beeinflusst werden und somit letztlich auch die Klimatisierung des Raumes R.The guide element 9 'according to Figure 2 is not firmly connected to the carrier plate 2 and is adjustable with regard to the angle β. This can influence the alignment of the partial volume flows (arrows 11, 12) and ultimately also the air conditioning of the room R.

In der Figur 3 ist ein alternatives Heiz- und Kühlsegel 1" gezeigt, wobei zusätzlich zu den Kanälen 4 ein Kühlregister 14 auf der Trägerplatte 2 angeordnet ist. Hierdurch kann die Temperierung des oberen Teilvolumenstroms (Pfeil 11) intensiver erfolgen.In the Figure 3 an alternative heating and cooling sail 1" is shown, with a cooling register 14 being arranged on the carrier plate 2 in addition to the channels 4. This allows the temperature control of the upper partial volume flow (arrow 11) to be carried out more intensively.
