Definitions
- the invention relates to a refrigerated cabinet, in particular refrigerated shelves, freezer, cooling island or refrigerated display, for storage and / or presentation of refrigerated goods, with a cooling space for the refrigerated goods and a channel assigned to the cooling chamber for supplying air, wherein two air flows at different flow rates from an outlet can flow out of the channel, which form a double protective air curtain in front of an access to the refrigerator.
- a refrigerator with a cooling space for the refrigerated goods and a channel associated with the cooling chamber for the supply of air is for example from the DE 34 14 033 A1 known.
- the refrigeration unit shown here is a refrigerated shelf in which cooling air in a channel on the rear wall of the cabinet is directed upwardly into a front portion of the refrigerator shelf and is discharged from an outlet in front of the refrigerator compartment to form a protective air curtain.
- the duct for supplying air is formed with two separate air ducts, each supplying air flows at different flow velocities.
- the air streams emerging from the duct tend to flow into the cold room rather than forming a protective air curtain in front of the cold room.
- This tendency is counteracted by the creation of additional support air curtains formed by airflows flowing out of the rear wall of the cold room into the cold room, which are intended to prevent the airstreams forming the protective air curtain from entering the cold room.
- Care is taken to ensure that these supporting air veils are generated from as laminar flows as possible in order to keep the air flows of the protective air curtain as safe as possible out of the cold room.
- the disadvantage of these laminar flows is that their cooling effect, which is also desired and likewise desired, is not very good, since these laminar streams of support air show only a short interaction time with the material to be cooled.
- the supporting air curtain flows past the refrigerated goods too quickly and in a straight line, in order to exert an effective cooling effect on the refrigerated goods.
- JP H03-271683 A is a cooling furniture removable, in which a cooling chamber 5 associated channel 16, 17 is implemented for supplying air, wherein two air flows at different flow velocities from an outlet 18 of the channel 16,17 can be flowed out, a protective air curtain in front of an access 3 to the Make refrigerator 5.

- the channel on such an applied to the supplied cooling air element that on the one hand by this element a division of the supplied air into two air flows and beyond also the different flow velocities of the two air flows are generated. It is in a structurally simple way on the one hand no longer necessary to realize a channel with two separate air ducts to perform the two required for a double protective air curtain air flows. It suffices in a structurally simple way a channel with a single air duct and a placed at a suitable location element.
- This design of the channel with only one air duct also has advantages in terms of hygienic requirements, since an easier cleaning of the channel is made possible with only one air duct. Furthermore, it has been found that this design of the channel with a division into the two air flows only at the element leads to a safer and quieter air flow. Finally, it has been shown that the inventive design of the channel with the element acting on the supplied air leads to a laminar over a relatively long distance flow of the protective air curtain, so that in previous cooling furniture required supporting air curtain to a much lesser extent or almost no longer required to maintain the protective air curtain as required. In other words, supporting air curtains no longer have to be conducted as tightly laminar as is required with conventional refrigerated cabinets. This allows the use of a more turbulent support air flow than before, so that an improved cooling effect can be exerted on the refrigerated goods. This results in significant energy savings in the required refrigeration.

- At least one of the guide elements arranged in front of the element has a plurality of planar guide elements arranged parallel to one another.
- Such planar guide elements offer a particularly simple and secure parallel guidance of the air flowing past them.
- At least one of the two guide devices arranged in front of and / or behind the element can be constructed from a plurality of individual sections. In that regard, a modular structure of the guide devices can be realized to accommodate a wide variety of requirements and application situations.

- the flow direction is indicated by an arrow 5.
- the protective air curtain extends in front of an access 6 to the cooling chamber 1 in order to suppress heat exchange with the warmer surroundings of the cooling cabinet.

Description
Die Erfindung betrifft ein Kühlmöbel, insbesondere Kühlregal, Kühltruhe, Kühlinsel oder Kühltheke, zur Aufbewahrung und/oder Präsentation von Kühlgut, mit einem Kühlraum für das Kühlgut und einem dem Kühlraum zugeordneten Kanal zur Zuführung von Luft, wobei zwei Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten aus einem Auslass des Kanals ausströmbar sind, die einen doppelten Schutzluftschleier vor einem Zugang zu dem Kühlraum bilden.The invention relates to a refrigerated cabinet, in particular refrigerated shelves, freezer, cooling island or refrigerated display, for storage and / or presentation of refrigerated goods, with a cooling space for the refrigerated goods and a channel assigned to the cooling chamber for supplying air, wherein two air flows at different flow rates from an outlet can flow out of the channel, which form a double protective air curtain in front of an access to the refrigerator.
Ein Kühlmöbel mit einem Kühlraum für das Kühlgut und einem dem Kühlraum zugeordneten Kanal zur Zuführung von Luft ist beispielsweise aus der
Des Weiteren ist es bekannt, einen derartigen Schutzluftschleier aus zwei geeigneten Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten zu bilden. Hierdurch wird eine besonders wirksame Isolation des Kühlraums von der üblicherweise wärmeren Umgebung realisiert. Zur Erzeugung eines derartigen doppelten Schutzluftschleiers ist der Kanal zur Zuführung von Luft mit zwei getrennten Luftkanälen ausgebildet, die jeweils Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten zuführen.Furthermore, it is known to form such a protective air curtain of two suitable air flows with different flow velocities. As a result, a particularly effective insulation of the cooling space is realized by the usually warmer environment. To produce such a double protective air curtain, the duct for supplying air is formed with two separate air ducts, each supplying air flows at different flow velocities.
Bei derartigen Kühlmöbeln ist es problematisch, dass die aus dem Auslass des Kanals ausströmenden Luftströmungen meist nur eine kurze Strecke und keinesfalls entlang des gesamten Kühlraums in der erforderlichen Weise laminar strömen. Dies hat zur Folge, dass der gewünschte Schutzluftschleier nicht sicher entlang dem gesamten Kühlraum ausgebildet werden kann.In the case of such cooling furniture, it is problematic that the air flows flowing out of the outlet of the channel usually flow in a laminar manner only a short distance and in no way along the entire cooling space in the required manner. This has the consequence that the desired protective air curtain can not be formed safely along the entire refrigerator.
Im Konkreten neigen die aus dem Kanal austretenden Luftströmungen meist dazu, in den Kühlraum hinein zu strömen anstatt einen Schutzluftschleier vor dem Kühlraum zu bilden. Dieser Tendenz wird durch die Erzeugung zusätzlicher Stützluftschleier entgegengewirkt, die durch aus der Rückwand des Kühlraums in den Kühlraum ausströmende Luftströmungen gebildet werden, die die den Schutzluftschleier bildenden Luftströmungen davon abhalten sollen, in den Kühlraum einzudringen. Dabei wird darauf geachtet, dass diese Stützluftschleier aus möglichst laminaren Strömungen erzeugt werden, um die Luftströmungen des Schutzluftschleiers möglichst sicher aus dem Kühlraum herauszuhalten. Der Nachteil dieser laminaren Strömungen besteht allerdings darin, dass deren auf das Kühlgut erzeugte und ebenfalls gewünschte Kühlwirkung nicht sehr gut ist, da diese laminaren Stützluftströmungen eine nur kurze Wechselwirkungsdauer mit dem Kühlgut zeigen. Mit anderen Worten strömt der Stützluftschleier zu schnell und zu geradlinig am Kühlgut vorbei, um eine wirksame Kühlwirkung auf das Kühlgut auszuüben.Concretely, the air streams emerging from the duct tend to flow into the cold room rather than forming a protective air curtain in front of the cold room. This tendency is counteracted by the creation of additional support air curtains formed by airflows flowing out of the rear wall of the cold room into the cold room, which are intended to prevent the airstreams forming the protective air curtain from entering the cold room. Care is taken to ensure that these supporting air veils are generated from as laminar flows as possible in order to keep the air flows of the protective air curtain as safe as possible out of the cold room. However, the disadvantage of these laminar flows is that their cooling effect, which is also desired and likewise desired, is not very good, since these laminar streams of support air show only a short interaction time with the material to be cooled. In other words, the supporting air curtain flows past the refrigerated goods too quickly and in a straight line, in order to exert an effective cooling effect on the refrigerated goods.
Das bekannte Kühlmöbel ist daher in energetischer Hinsicht nachteilig, da nämlich für die Erzeugung eines sicheren und entlang des gesamten Kühlraums zuverlässig strömenden Schutzluftschleiers zusätzliche möglichst laminar strömende Stützluftschleier durch den Kühlraum und aus dem Kühlraum heraus erzeugt werden müssen, die jedoch aufgrund ihrer angestrebten Laminarität keine besonders wirkungsvolle Kühlung des Kühlguts bewirken. Im Ergebnis muss sehr viel Energie zur sicheren Kühlung des Kühlguts aufgebracht werden.The well-known refrigerated cabinets is therefore disadvantageous in terms of energy, since additional as laminar flowing Stützluftschleier must be generated by the refrigerator and out of the refrigerator for the production of safe and reliable along the entire cold storage protective air curtain, but due to their desired laminarity no special effect effective cooling of the refrigerated goods. As a result, a great deal of energy has to be applied for the safe cooling of the refrigerated goods.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Kühlmöbel der eingangs genannten Art derart auszugestalten und weiterzubilden, dass eine wirkungsvolle und energiesparende Kühlung des Kühlguts mit konstruktiv einfachen Mitteln ermöglicht ist.The present invention has for its object to provide a cooling cabinet of the type mentioned in such a way and further that an effective and energy-saving cooling of the refrigerated goods with structurally simple means is possible.
Die voranstehende Aufgabe wird durch ein Kühlmöbel mit den Merkmalen des Anspruchs 1 gelöst. Danach ist das Kühlmöbel derart ausgestaltet und weitergebildet, dass der Kanal ein derart auf die zugeführte Luft einwirkendes Element aufweist, dass eine Aufteilung der zugeführten Luft in die zwei Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten durch das Element realisiert ist.The above object is achieved by a refrigerated cabinet with the features of
In erfindungsgemäßer Weise ist zunächst erkannt worden, dass durch geschickte Erzeugung und Führung zweier kühlender Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten, die den Schutzluftschleier bilden, die voranstehende Aufgabe auf überraschend einfache Weise gelöst wird. Hierzu weist in weiter erfindungsgemäßer Weise der Kanal ein derart auf die zugeführte kühlende Luft einwirkendes Element auf, dass durch dieses Element einerseits eine Aufteilung der zugeführten Luft in zwei Luftströmungen und darüber hinaus auch noch die unterschiedlichen Strömungsgeschwindigkeiten der beiden Luftströmungen erzeugt werden. Dabei ist es in konstruktiv einfacher Weise einerseits nicht mehr erforderlich, einen Kanal mit zwei separaten Luftkanälen zu realisieren, um die beiden für einen doppelten Schutzluftschleier erforderlichen Luftströmungen zu führen. Es genügt in konstruktiv einfacher Weise ein Kanal mit einem einzigen Luftkanal und einem an geeigneter Stelle platzierten Element. Diese Ausbildung des Kanals mit lediglich einem Luftkanal hat auch hinsichtlich hygienischer Anforderungen Vorteile, da eine leichtere Reinigung des Kanals mit nur einem Luftkanal ermöglicht ist. Des Weiteren hat sich gezeigt, dass diese Ausgestaltung des Kanals mit einer Aufteilung in die beiden Luftströmungen erst am Element zu einer sichereren und leiseren Luftführung führt. Schließlich hat sich gezeigt, dass die erfindungsgemäße Ausgestaltung des Kanals mit dem auf die zugeführte Luft einwirkenden Element zu einer über eine relativ lange Wegstrecke laminaren Strömung des Schutzluftschleiers führt, so dass bei bisherigen Kühlmöbeln erforderliche Stützluftschleier in weitaus geringerem Ausmaß oder fast gar nicht mehr erforderlich sind, um den Schutzluftschleier in der erforderlichen Weise aufrechtzuerhalten. Mit anderen Worten müssen Stützluftschleier nicht mehr so streng laminar geführt werden, wie dies bei herkömmlichen Kühlmöbeln erforderlich ist. Dies ermöglicht den Einsatz einer turbulenteren Stützluftströmung als bisher, so dass eine verbesserte Kühlwirkung auf das Kühlgut ausgeübt werden kann. Hierdurch ergeben sich deutliche Energieeinsparungen bei der erforderlichen Kälteerzeugung.In accordance with the invention, it has first been recognized that the above object is achieved in a surprisingly simple manner by skillfully producing and guiding two cooling air flows at different flow velocities, which form the protective air curtain. For this purpose, in a further inventive manner, the channel on such an applied to the supplied cooling air element that on the one hand by this element a division of the supplied air into two air flows and beyond also the different flow velocities of the two air flows are generated. It is in a structurally simple way on the one hand no longer necessary to realize a channel with two separate air ducts to perform the two required for a double protective air curtain air flows. It suffices in a structurally simple way a channel with a single air duct and a placed at a suitable location element. This design of the channel with only one air duct also has advantages in terms of hygienic requirements, since an easier cleaning of the channel is made possible with only one air duct. Furthermore, it has been found that this design of the channel with a division into the two air flows only at the element leads to a safer and quieter air flow. Finally, it has been shown that the inventive design of the channel with the element acting on the supplied air leads to a laminar over a relatively long distance flow of the protective air curtain, so that in previous cooling furniture required supporting air curtain to a much lesser extent or almost no longer required to maintain the protective air curtain as required. In other words, supporting air curtains no longer have to be conducted as tightly laminar as is required with conventional refrigerated cabinets. This allows the use of a more turbulent support air flow than before, so that an improved cooling effect can be exerted on the refrigerated goods. This results in significant energy savings in the required refrigeration.
Folglich ist mit dem erfindungsgemäßen Kühlmöbel ein Kühlmöbel realisiert, bei dem eine wirkungsvolle und energiesparende Kühlung des Kühlguts mit konstruktiv einfachen Mitteln ermöglicht ist.Consequently, a cooling furniture is realized with the cooling furniture according to the invention, in which an effective and energy-saving cooling of the cooling material is made possible with structurally simple means.
In für die sichere Erzeugung der Luftströmungen mit unterschiedlichen Strömungsgeschwindigkeiten sicherer und konstruktiv einfacher Weise kann das Element in dem Kanal oder im Bereich des Auslasses des Kanals angeordnet sein. Die Anordnung in dem Kanal bietet eine vor äußerlichen Einwirkungen geschützte und wirkungsvolle Anordnung des Elements. Je nach Erfordernis kann diese Anordnung im Bereich des Auslasses vorgenommen sein. Es ist auch denkbar, das Element im Wesentlichen vor dem Auslass des Kanals zu positionieren, um eine gute Zugänglichkeit zu dem Element im Hinblick auf Reinigung und/oder Wartung zu gewährleisten.In the safe generation of air currents with different flow velocities safe and constructively simple way, the element in be arranged in the channel or in the region of the outlet of the channel. The arrangement in the channel provides an externally protected and effective arrangement of the element. Depending on requirements, this arrangement may be made in the area of the outlet. It is also conceivable to position the element substantially in front of the outlet of the channel in order to ensure good accessibility to the element with regard to cleaning and / or maintenance.
In besonders wirkungsvoller und eleganter Weise wird das Element unter Ausnutzung des Bernoulli-Effekts flügelartig ausgebildet. Eine derartige flügelartige Ausbildung des Elements gewährleistet einerseits eine sichere Aufteilung der am Element vorbeiströmenden zugeführten Luft in zwei Luftströmungen und andererseits eine sichere Erzeugung unterschiedlicher Strömungsgeschwindigkeiten der Luftströmungen auf den beiden Seiten des flügelartigen Elements. Aufgrund von durch das flügelartige Element erzeugten Luftdruck-Unterschieden auf den unterschiedlichen Seiten des flügelartigen Elements ergeben sich durch die individuelle Ausgestaltung des Elements bedingte Unterschiede in den Strömungsgeschwindigkeiten der beiden Luftströmungen. Je nach Ausgestaltung des flügelartigen Elements sind somit unterschiedliche Strömungsgeschwindigkeiten der beiden Luftströmungen -je nach gewünschtem Anwendungsfall - realisierbar.
Im Hinblick auf einen besonders vielseitigen Einsatz und im Hinblick auf individuelle Anpassungsmöglichkeiten der erzeugten Luftströmungen an individuell vorliegende Erfordernisse kann das Element relativ zu dem Kanal verstellbar und/oder relativ zu dem Kanal um eine Achse verschwenkbar und/oder relativ zu dem Kanal verschiebbar angeordnet sein. Je nach Verstell-, Verschwenk- oder Verschiebeposition können unterschiedliche Strömungsgeschwindigkeiten und ein unterschiedliches Strömungsverhalten der beiden Luftströmungen realisiert werden. Die Achse, um die das Element verschwenkt werden kann, kann im Wesentlichen senkrecht zu den Strömungsrichtungen der Luftströmungen angeordnet sein.
Im Hinblick auf eine alternative oder zusätzliche individuelle Erzeugung der Luftströmungen und der jeweiligen Strömungsgeschwindigkeiten kann das Element mehrere relativ zueinander vestellbare und/oder verschwenkbare Abschnitte aufweisen. Bei dieser Ausgestaltung lässt sich das Element in vorteilhafter Weise im Umfang der Verstellbarkeit der Abschnitte - individuell - ausgestalten oder formen. Eine Anpassung an unterschiedlichste Anwendungsfälle ist hierdurch ermöglicht.
Zur Erzeugung eines Schutzluftschleiers, der über eine möglichst weite Strecke eine laminare Strömung aufweist, kann - in Strömungsrichtung gesehen vor dem Element - in dem Kanal eine Führungseinrichtung zur Parallelführung der zugeführten Luft angeordnet sein. Durch diese vorausgehende Parallelführung der zugeführten Luft wird eine laminare Strömung mit möglichst langer Reichweite im Bereich des Schutzluftschleiers erzeugt. Dabei erfolgt quasi eine Vorausrichtung der zugeführten Luft, so dass nach der Aufteilung der zugeführten Luft in die beiden Luftströmungen eine besonders weitreichende laminare Strömung erzeugt wird.In a particularly effective and elegant manner, the element is formed wing-like using the Bernoulli effect. Such a wing-like design of the element ensures, on the one hand, a reliable division of the air flowing past the element into two air flows and, on the other hand, a reliable generation of different flow velocities of the air flows on the two sides of the wing-like element. Due to the air pressure differences generated by the wing-like element on the different sides of the wing-like element resulting from the individual design of the element conditional differences in the flow velocities of the two air currents. Depending on the design of the wing-like element thus different flow velocities of the two air currents - depending on the desired application - can be realized.
With regard to a particularly versatile use and with regard to individual adaptation possibilities of the generated air flows to individually present requirements, the element can be arranged relative to the channel adjustable and / or relative to the channel pivotable about an axis and / or displaceable relative to the channel. Depending on the adjustment, pivoting or displacement position different flow velocities and a different flow behavior of the two air flows can be realized. The axis about which the element can be pivoted can be arranged substantially perpendicular to the flow directions of the air flows.
With regard to an alternative or additional individual generation of the air flows and the respective flow velocities, the element can have a plurality of sections which can be set and / or pivoted relative to one another. In this embodiment, the element can be advantageously in Scope of adjustability of sections - individually - designed or shaped. An adaptation to a wide variety of applications is possible.
To produce a protective air curtain, which has a laminar flow over the greatest possible distance, a guide device for parallel guidance of the supplied air can be arranged in the channel in the direction of flow in front of the element. By means of this preliminary parallel guidance of the supplied air, a laminar flow with the longest possible range in the area of the protective air curtain is generated. In this case, there is virtually a pre-alignment of the supplied air, so that after the division of the supplied air into the two air flows, a particularly far-reaching laminar flow is generated.
Zur Parallelführung der zwei Luftströmungen wird - in Strömungsrichtung gesehen nach dem Element eine Führungseinrichtung in dem Kanal angeordnet. Hierdurch wird die bereits in zwei Luftströmungen aufgeteilte Luft nach ihrer Aufteilung parallel geführt, so dass auch hierdurch eine Verlängerung der laminaren Strömung im Schutzluftschleier erreicht wird.For parallel guidance of the two air flows is - seen in the flow direction after the element a guide device in the channel. As a result, the already divided into two air currents air is guided in parallel after their division, so that also an extension of the laminar flow is achieved in the protective air curtain.
Mindestens eine der vor dem Element angeordneten Führungseinrichtungen weist mehrere parallel zueinander angeordnete flächige Leitelemente auf. Derartige flächige Leitelemente bieten eine besonders einfache und sichere Parallelführung der an ihnen vorbei strömenden Luft.
Zumindest eine der beiden vor und/oder nach dem Element angeordneten Führungseinrichtungen kann aus mehreren Einzelabschnitten aufgebaut sein. Insoweit ist ein modularer Aufbau der Führungseinrichtungen realisierbar, um unterschiedlichsten Erfordernissen und Anwendungssituationen Rechnung zu tragen.At least one of the guide elements arranged in front of the element has a plurality of planar guide elements arranged parallel to one another. Such planar guide elements offer a particularly simple and secure parallel guidance of the air flowing past them.
At least one of the two guide devices arranged in front of and / or behind the element can be constructed from a plurality of individual sections. In that regard, a modular structure of the guide devices can be realized to accommodate a wide variety of requirements and application situations.
Der Kanal weist einen weiteren sich in den Kühlraum öffnenden Auslass für die zugeführte Luft auf, wobei der mindestens eine weitere Auslass derart ausgebildet ist, dass in den Kühlraum einströmende Luft im Wesentlichen turbulent ist und vorzugsweise einen Stützluftschleier für den Schutzluftschleier bildet. Dabei kann - dank dem erfindungsgemäßen Vorteil einer besonders weitreichenden laminaren Strömung im Schutzluftschleier durch die Verwendung des Elements - mit der turbulenten Strömung im Stützluftschleier eine besonders wirkungsvolle Kühlung des Kühlguts erreicht werden. Durch die turbulente Strömung ist eine länger andauernde und damit sicherere Wechselwirkung zwischen der Luft und dem Kühlgut zur Kühlung des Kühlguts erreicht. Hierdurch lassen sich erhebliche Mengen an Energie für die Kühlung des Kühlguts einsparen.The channel has a further outlet opening into the cooling chamber for the supplied air, wherein the at least one further outlet is designed such that air flowing into the cooling chamber is substantially turbulent and preferably forms a supporting air curtain for the protective air curtain. It can - thanks to the inventive advantage of a particularly far-reaching laminar flow in the protective air curtain through the Use of the element - with the turbulent flow in the supporting air curtain, a particularly effective cooling of the refrigerated goods can be achieved. Due to the turbulent flow, a longer-lasting and therefore safer interaction between the air and the refrigerated goods for cooling the refrigerated goods is achieved. This can save considerable amounts of energy for cooling the chilled goods.
Mit dem erfindungsgemäßen Kühlmöbel ist eine Kombination aus turbulenter Strömung im Kühlraum und laminarer Strömung im Schutzluftschleier in energetisch besonders günstiger Weise realisierbar. Diese Kombination erzeugt neben einem sehr wirkungsvollen Wärmetausch im Kühlraum einen Schutzluftschleier mit unterschiedlichen Strömungsgeschwindigkeiten, der außerordentlich stabil gegen äußere Störeinflüsse wie beispielsweise Wärmeströmungen zum Kühlmöbel wirkt. Hierdurch ergibt sich eine besonders hohe Energieeffizienz bei dem erfindungsgemäßen Kühlmöbel.With the cooling furniture according to the invention, a combination of turbulent flow in the cooling space and laminar flow in the protective air curtain in energetically particularly favorable manner can be realized. This combination, in addition to a very effective heat exchange in the refrigerator a protective air curtain with different flow rates, which acts extremely stable against external disturbances such as heat flow to the refrigerator. This results in a particularly high energy efficiency in the cooling furniture according to the invention.
Das erfindungsgemäße Kühlmöbel kann sowohl ein Kühlmöbel mit eigenem Verflüssigungsaggregat sein - ein sogenanntes steckerfertiges Kühlmöbel - als auch ein Kühlmöbel mit einem Anschluss an ein zentrales Kälteaggregat mit beispielsweise einem Rohrverbundnetz.The refrigerator according to the invention can be both a refrigerated cabinet with its own condensing unit - a so-called plug-in refrigerated cabinets - as well as a refrigerated cabinet with a connection to a central refrigeration unit with, for example, a composite pipe network.
