Description

Die Erfindung betrifft eine Deckenkühleinrichtung mit einer von einem Kühlmittel durchströmten Kühlschlange.The invention relates to a ceiling cooling device with a cooling coil through which a coolant flows.

Derartige Deckenkühleinrichtungen sind bekannt. Die Kühlschlangen werden in der Regel von einem Kältemittel durchströmt, das mit einem üblichen Kälteprozess jeweils wieder abgekühlt wird. Es lässt sich deckennah Kaltluft erzeugen, die durch Strahlung und Konvektion die erwünschte Raumkühlung erbringt.Such ceiling cooling devices are known. The cooling coils are usually flowed through by a refrigerant, which is cooled again with a conventional cooling process. It can generate close to the ceiling cold air, which provides the desired space cooling by radiation and convection.

Andererseits bestehen hinsichtlich eines Raumes, in welchem sich Menschen aufhalten, noch weitere Anforderungen. So sollen insbesondere auch akustisch vorteilhafte Bedingungen gegeben sein. In diesem Zusammenhang ist es bereits bekannt, durch deckennah aufgehängte Absorber auf Schaumstoffbasis eine Schallreduzierung zu erreichen.On the other hand, there are other requirements with regard to a space in which people reside. In particular, acoustically advantageous conditions should also be given. In this context, it is already known to achieve a sound reduction by near-ceiling suspended foam-based absorbers.

Ausgehend von dem vorbeschriebenen Stand der Technik stellt sich der Erfindung die Aufgabe, die Behaglichkeit in einem von Menschen genutzten Raum, insbesondere hinsichtlich Temperatur und Schall, vorteilhaft zu beeinflussen.Based on the above-described prior art, the object of the invention is to advantageously influence the comfort in a space used by people, in particular with regard to temperature and sound.

Diese Aufgabe ist zunächst und im Wesentlichen beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass unterhalb der und in Überdeckung zu einer Kühlschlange ein Schallabsorber in Form eines luftdurchlässigen, flächigen Schaumstoffelementes angeordnet ist. Erfindungsgemäß ist eine Kombination der bislang für sich bekannten Funktionselemente Kühlschlangen und Schallabsorber vorgenommen. Die Anordnung des Schallabsorbers unterhalb der Kühlschlange ist nicht nur mit dem offensichtlichen Vorteil verbunden, dass die Kühlschlange der Sicht entzogen ist. Vielmehr ergibt sich hierdurch auch eine deutlich vorteilhafte Beeinflussung hinsichtlich der Strömungs- und Temperaturbehaglichkeit in einem solchen Raum. Das flächige Schaumstoffelement verteilt die Kühlwirkung der Kühlschlange auf eine relativ große Fläche. Dies verbunden mit einem Vergleichmäßigungseffekt hinsichtlich der Temperaturen. In dem Raum sich aufhaltende Personen sind nicht mehr in unmittelbarem Strahlungsaustausch zu den Kühlschlangen, sondern nur im Strahlungsaustausch zu dem darunter befindlichen Schaumstoffelement. Dadurch, dass das Schaumstoffelement luftdurchlässig ist, kann von dem Kühlelement erzeugte kalte Luft hierin eindringen. Die kalte Luft wird nicht nur oberseitig des Schaumstoffelementes erzeugt und muss etwa durch zwischen mehrere nebeneinander aufgehängten Schaumstoffelementen über Spalte nach unten abströmen. Sie kann die gesamte Fläche zum Abströmen, wenn auch mit unterschiedlichen Geschwindigkeiten der hier sich bewegenden Luft, nutzen. Zugleich ist die akustische Wirkung der Schallabsorber praktisch unbeeinflusst.This object is achieved first and foremost in the subject matter of claim 1, wherein it is based on the fact that a sound absorber in the form of an air-permeable, flat foam element is arranged below and in overlap with a cooling coil. According to the invention, a combination of the hitherto known functional elements cooling coils and sound absorbers is made. The arrangement of the sound absorber below the cooling coil is not only associated with the obvious advantage that the cooling coil is removed from view. Rather, this results in a significantly advantageous effect on the flow and temperature comfort in such a room. The areal Foam element distributes the cooling effect of the cooling coil on a relatively large area. This combined with a homogenizing effect in terms of temperatures. People staying in the room are no longer in direct radiation exchange with the cooling coils, but only in the radiation exchange with the underlying foam element. The fact that the foam element is permeable to air, cold air generated by the cooling element can penetrate therein. The cold air is not only generated on the upper side of the foam element and has to flow down through gaps between several juxtaposed foam elements. It can use the entire surface for outflow, albeit at different speeds of the air moving here. At the same time, the acoustic effect of the sound absorber is virtually unaffected.

In vorteilhafter Ausgestaltung ist vorgesehen, dass das Schaumstoffelement aus einem weitestgehend offenporigem Schaumstoff besteht. Es sind Schaumstoffe bekannt, die luftdurchlässig sind, jedoch unterschiedliche Porigkeit aufweisen. Insbesondere sind grundsätzlich auch solche Schaumstoffe luftdurchlässig, die eine gewisse, wenn auch noch eben luftdurchlässige Verhautung aufweisen. Bevorzugt ist hier ein Schaumstoff, der in diesem Sinne unverhautet ist und weitestgehend, d. h. zu mehr als achtzig Prozent seiner Poren, offenporig ist. Besonders bevorzugt ist ein Melaminharzschaumstoff, der praktisch hundert Prozent offenporig ist.In an advantageous embodiment, it is provided that the foam element consists of a largely open-cell foam. Foams are known which are permeable to air but have different porosity. In particular, in principle, such foams are permeable to air, which have a certain, if still just air-permeable skin formation. Preferred here is a foam, which is not cut in this sense and as far as possible, d. H. to more than eighty percent of its pores, it is porous. Particularly preferred is a melamine resin foam, which is almost 100 percent open-pore.

Der Schallabsorber, bestehend grundsätzlich aus einem Schaumstoff, insbesondere wie vorstehend beschrieben, ist weiter bevorzugt jedenfalls auf einer Flachseite, nämlich der dem Raum zugewandten Flachseite, mit einem Vlies überzogen. Es kann sich hier um ein Gasfaservlies handeln. Bevorzugt um ein solches mit einer Beschichtung wie etwa Aluminumhydroxidbeschichtung. Das Vlies kann ein Flächengewicht von 150 bis 250, bevorzugt etwa 200 g/m2 aufweisen. Es kann auf den Schaumstoff aufkaschiert sein. Insbesondere aber auch mit Thermokleberpunkten aufgeklebt sein.The sound absorber, consisting basically of a foam, in particular as described above, is more preferably at least on a flat side, namely the space facing the flat side, coated with a nonwoven. It can be a gas-fiber fleece here. Preferably, such with a coating such as aluminum hydroxide coating. The nonwoven may have a basis weight of 150 to 250, preferably about 200 g / m 2 . It can be laminated on the foam. In particular, but also be glued with thermocouple dots.

Hinsichtlich der Kühlschlange ist bevorzugt, dass diese frei liegend, aber mit geringem vertikalem Abstand oberhalb eines Schaumstoffelementes verläuft. Sowohl die Kühlschlange wie auch das Schaumstoffelement sind jeweils bevorzugt horizontal verlaufend angeordnet.With regard to the cooling coil, it is preferred that this runs freely, but at a small vertical distance above a foam element. Both the cooling coil and the foam element are each preferably arranged to extend horizontally.

Dadurch, dass die Kühlschlange frei liegend angeordnet ist, kann, aufgrund etwa sich in Bezug auf eine im Raum befindliche Konvektion ergebende Luftströmung, kalte Luft entstehen und wieder abfließen. Hierbei kann die kalte Luft, wie grundsätzlich schon angesprochen, zum einen in das darunterliegende Schaumstoffelement einsickern. Aufgrund der Offenporigkeit wird nahezu das gesamte von dem Schaumstoffelement eingenommene Volumen mit kalter Luft gefüllt und hierbei aber auch in gewisser Weise zusammengehalten. Es entsteht praktisch ein durch die Schaumstoffstruktur mit einer gewissen Stabilität versehener "See" an kalter Luft in den Schaumstoffelementen. Zudem kann sich eine weitere Strömung von gekühlter Luft ergeben durch zwischen solchen Schaumstoffelementen belassene Freiräume. Wesentlich ist auch die durch Konvektion unterseitig etwa an den Schaumstoffelementen vorbei streichende Kaltluft aus den Schaumstoffelementen. Etwa in gewisser Beziehung vergleichbar dem Prinzip einer Wasserstrahlpumpe wird kalte Luft in die konvektiv vorbeistreichende wärmere Luft eingespeist.By virtue of the fact that the cooling coil is arranged lying freely, cold air can form and flow away due to, for example, the flow of air resulting in convection in the room. Here, the cold air, as already mentioned, on the one hand infiltrate into the underlying foam element. Due to the open porosity, almost all of the volume occupied by the foam element volume is filled with cold air and this also held together in some way. The result is practically provided by the foam structure with a certain stability "sea" of cold air in the foam elements. In addition, a further flow of cooled air can result from left between such foam elements open spaces. It is also essential by convection on the underside about the foam elements passing cold air from the foam elements. In some ways comparable to the principle of a water jet pump, cold air is fed into the convection-passing warmer air.

Grundsätzlich ist es auch möglich, wenn auch derzeit nicht bevorzugt, die Wärmeübertragung, sei es nun im Hinblick auf die Schaumstoffelemente und/oder im Hinblick auf die Kühlschlange, durch eine Zwangsströmung, etwa hervorgerufen durch einen Ventilator, zu verstärken.In principle, it is also possible, although not currently preferred, to enhance the heat transfer, be it with regard to the foam elements and / or with regard to the cooling coil, by means of a forced flow, for example caused by a fan.

Die Schaumstoffelemente sind weiter ihrerseits bevorzugt in einem Rahmenelement aufgenommen. Es kann sich hier um einen Aluminiumrahmen handeln. Der Rahmen übergreift unterseitig, am Rand, das Schaumstoffelement, um dieses dadurch entsprechend zu haltern. Der Übergriff kann sich im Bereich von 1 bis 20 mm, bevorzugt bei 1,5 bis 10 mm, bewegen.The foam elements are further in turn preferably received in a frame member. This can be an aluminum frame. The frame overlaps on the underside, at the edge, the foam element in order to hold this accordingly. The attack can range from 1 to 20 mm, preferably from 1.5 to 10 mm.

Oberseitig weist der Rahmen bevorzugt im Querschnitt eine hakenförmige Gestaltung auf, in welche wiederum ein zweiter Haken einfach formschlüssig eingreifen kann, der seinerseits dann an der Decke befestigt ist, womit insgesamt der Absorber dann an der Decke abgehängt ist. Es versteht sich, dass für einen Absorber je nach Größe eine Mehrzahl solcher Abhängungen erforderlich sind. Die übliche Größe eines Absorbers kann 2 bis 5 m2 betragen. Hierbei ist die Dicke des Absorbers (bezogen auf den Schaumstoff) bevorzugt im Bereich von 20 bis 50 mm.On the upper side, the frame preferably has a hook-shaped configuration in cross-section, in which in turn a second hook can engage in a form-fitting manner, which in turn is then fastened to the ceiling, whereby the absorber is then suspended from the ceiling. It is understood that for an absorber depending on the size of a plurality of such suspensions are required. The usual size of an absorber can be 2 to 5 m 2 . Here, the thickness of the absorber (based on the foam) is preferably in the range of 20 to 50 mm.

Die Kühlschlangen können auch auf dem Rahmen abgestützt sein. Weiter können Sie aber auch eigenständig an der Decke abgehängt sein.The cooling coils can also be supported on the frame. Furthermore, you can also be suspended independently from the ceiling.

Nachstehend ist die Erfindung des Weiteren anhand der beigefügten Zeichnung, die jedoch lediglich ein Ausführungsbeispiel darstellt, näher erläutert. Hierbei zeigt:

Fig. 1
eine schematische Querschnittsansicht eines Raumes mit deckenseitig aufgehängter Kühlstruktur;
Fig. 2
eine Schnittdarstellung durch die Darstellung gemäß Fig. 1, geschnitten entlang der Linie II-II, jedoch fokussiert auf drei exemplarisch herausgezeichnete Schaumstoffelemente mit darüber befindlicher Kühlschlange.
The invention will be explained in more detail below with reference to the attached drawing, which, however, represents only one embodiment. Hereby shows:
Fig. 1
a schematic cross-sectional view of a room with ceiling-mounted suspended cooling structure;
Fig. 2
a sectional view through the illustration of FIG. 1, taken along the line II-II, but focused on three exemplified excelled foam elements with overhead cooling coil.

Dargestellt und beschrieben ist, mit Bezug zu Fig. 1, ein Raum 1 eines Gebäudes, das in dem Beispielfall an einer Wand 2, die eine Außenwand ist, ein Fenster 3 aufweist und gegenüberliegend eine Wand 4, die durchgehend geschlossen ausgebildet ist. Weiter weist der Raum einen Boden 5 und eine Decke 6 auf.With reference to FIG. 1, there is shown and described a room 1 of a building, which in the example case has a window 3 on a wall 2, which is an outer wall, and a wall 4 opposite, which is formed continuous closed. Furthermore, the room has a floor 5 and a ceiling 6.

Abgehängt von der Decke 6 sind flächige Schaumstoffelemente 7 angeordnet, die im Einzelnen aus im umlaufenden Rahmen 8 angeordneten quaderförmigen Schaumstoffelementen 7 rechteckigen Grundrisses bestehen. Diese Schaumstoffelemente können beispielsweise eine Grundflächenabmessung von 1 x 0,5 bis 6 x 2,5 m, bevorzugt von 3 x 1,25 m aufweisen. Sie können eine Dicke im Bereich von 10 bis 100 mm, bevorzugt etwa 30 bis 50 mm, weiter bevorzugt etwa 40 mm aufweisen. Beim Ausführungsbeispiel haben sie eine Dicke von 42 mm.Deposed from the ceiling 6 are flat foam elements 7 are arranged, which consist in detail of arranged in the surrounding frame 8 cuboid foam elements 7 rectangular plan. These foam elements may, for example, have a base area dimension of 1 × 0.5 to 6 × 2.5 m, preferably 3 × 1.25 m. They may have a thickness in the range of 10 to 100 mm, preferably about 30 to 50 mm, more preferably about 40 mm. In the embodiment, they have a thickness of 42 mm.

Mit hier nur schematisch angedeuteten Winkelelementen 9 sind die Schaumstoffelemente 7 an der Decke 6 abgehängt.With here only schematically indicated angle elements 9, the foam elements 7 are suspended from the ceiling 6.

Über die Fläche der Decke 6 verteilt sind eine Vielzahl von Schaumstoffelementen 7 angeordnet. Zwischen zwei Schaumstoffelementen 7 bzw. dessen Rahmen 8 verbleibt beim Ausführungsbeispiel jeweils ein Freiraum 10. Dieser Freiraum 10 kann umlaufend gegeben sein oder nur bezüglich einer Schmalseite oder einer Langseite.Distributed over the surface of the ceiling 6 a plurality of foam elements 7 are arranged. Between two foam elements 7 and its frame 8 remains in the embodiment each have a free space 10. This space 10 may be given circumferentially or only with respect to a narrow side or a long side.

Oberhalb der Schaumstoffelemente 7 verläuft, wie sich insbesondere auch aus Fig. 2 ergibt, eine Kühlschlange 11. Diese ist mäanderartig oberhalb jedes Schaumstoffelementes 7 geführt, wobei auch hier die Darstellung nur schematisch ist. Die Kühlschlange kann auch noch durch Metallflächenteile untereinander verbunden sein.Above the foam elements 7 extends, as is apparent in particular from Fig. 2, a cooling coil 11. This is meandering above each foam element 7 out, with the representation is only schematically here. The cooling coil can also be interconnected by metal surface parts.

Wesentlich ist weiter, dass die Kühlung, jedenfalls bei dem Ausführungsbeispiel, allein durch einen Anschluss an die Kaltwasserleitung eines Hauses erreicht ist. Ein besonderes Kühlaggregat und/oder ein Kältemittelkreislauf ist nicht erforderlich. Gleichwohl kann natürlich auch derartiges vorgesehen sein.It is also essential that the cooling, at least in the embodiment, achieved solely by a connection to the cold water pipe of a house is. A special cooling unit and / or a refrigerant circuit is not required. Of course, such things may of course be provided.

Die Schaumstoffelemente 7 füllen sich aufgrund der Kühlschlangen 11, an denen Warmluft bis auf etwa die Temperatur der Kühlschlangen, also bei Kaltwasser zwischen 10 und 15°, abkühlt, mit kalter Luft. Darüber hinaus kann an den Kühlschlangen abgekühlte Luft auch entsprechend den Pfeilen 12 unmittelbar nach unten strömen.The foam elements 7 fill up due to the cooling coils 11, where hot air to about the temperature of the cooling coils, ie in cold water between 10 and 15 °, cools with cold air. In addition, air cooled on the cooling coils can also flow directly downward in accordance with the arrows 12.

Deckennahe Luftschichten werden entsprechend auch hierdurch gekühlt und es ergibt sich eine konvektive Luft entsprechend etwa den Pfeilen 13. Hierbei wird gekühlte Luft entsprechend den Pfeilen 14 aus den Schaumstoffelementen 7 gleichsam eingespeist.Ceiling air layers are cooled accordingly by this and there is a convective air corresponding approximately to the arrows 13. Here, cooled air is fed according to the arrows 14 from the foam elements 7 as it were.
