Description

Die Erfindung betrifft ein Warenpräsentationsmöbel, insbesondere eine Kühltheke, mit wenigstens einem Verdampfer und/oder Wärmetauscher, in dem ein gekühlter Luftstrom erzeugt wirdThe invention relates to a product display cabinet, in particular a refrigerated counter, with at least one evaporator and / or heat exchanger, in which a cooled Airflow is generated

Unter dem Begriff "Warenpräsentationsmöbel" seien Möbel jeglicher Art, die der Präsentation und/oder Lagerung von Waren dienen, insbesondere (Tiefkühl- bzw. Kühl)Regale bzw. -Schränke, (Tiefkühl- bzw. Kühl)Truhen, (Tiefkühl- bzw. Kühl)Inseln, (Kühl)Theken, etc., zu verstehen.Under the term "goods presentation furniture" furniture of any kind that the Serve presentation and / or storage of goods, in particular (frozen or Cooling) shelves or cupboards, (freezer or cooling) chests, (freezer or cooling) islands, (Refrigerated) counters, etc. to understand.

Bei gattungsgemäßen Warenpräsentationsmöbeln, insbesondere bei Kühltheken, stellt sich das Problem, dass die in diesen Möbeln angebotenen Waren - insbesondere Fleisch-, Wurst- oder Fischwaren - über einen längeren Zeitraum einen möglichst frischen Eindruck auf den Kunden machen sollen, um dessen Kaufverhalten positiv zu beeinflussen. Um dies zu erreichen, ist die Aufrechterhaltung einer bestimmten relativen Feuchte in dem Möbel bzw. dessen Warenraum erforderlich.With generic goods presentation furniture, especially with refrigerated counters, provides the problem that the goods offered in this furniture - in particular Meat, sausage or fish products - if possible over a longer period of time should make a fresh impression on the customer in order to positively influence their buying behavior influence. To accomplish this is maintaining a certain one relative humidity in the furniture or its goods room required.

Die Kühlung des oder der Warenräume bzw. Warenauslagen gattungsgemäßer Warenpräsentationsmöbel wird im Regefall dadurch erreicht, dass in dem Möbel ein gekühlter Luftstrom erzeugt wird und dieser Kühlluftstrom im Möbel derart zirkuliert, dass er die in dem Möbel angebotenen Waren überstreicht und dabei kühlt. Bei dieser Art der Kühlung tritt jedoch das Problem auf, dass die Luftfeuchtigkeit in dem Kühlluftstrom vergleichsweise niedrig ist, da dieser bei dem Durchgang durch den Verdampfer bzw. Wärmetauscher entfeuchtet wird. Die Feuchtigkeit schlägt sich an dem Verdampfer bzw. Wärmetauscher in Form von Schnee und Eis nieder. Diese Entfeuchtung der Kühlluft hat zur Folge, dass die angebotenen Waren ebenfalls entfeuchtet werden, wodurch Ihre optische Präsentation beeinträchtigt wird.The cooling of the goods room or goods displays of the generic type Merchandise display furniture is usually achieved in that one in the furniture cooled air flow is generated and this cooling air flow circulates in the furniture in such a way that he sweeps over the goods offered in the furniture and cools it. At this The type of cooling, however, causes the problem that the humidity in the Cooling air flow is comparatively low, since it passes through the Evaporator or heat exchanger is dehumidified. The moisture sets in the evaporator or heat exchanger in the form of snow and ice. This Dehumidification of the cooling air has the consequence that the goods offered as well be dehumidified, which affects your visual presentation.

Prinzipiell können derartige Warenpräsentationsmöbel, die wenigstens einen Verdampfer aufweisen, bzw. deren Verdampfer auf zwei unterschiedliche Arten - nämlich kontinuierlich oder zyklisch - betrieben werden. In principle, such goods display furniture, the at least one Have evaporators, or their evaporators in two different ways - namely continuously or cyclically - operated.

Wird der Verdampfer kontinuierlich betrieben, so wird der in dem Möbel zirkulierende (Kühl)Luftstrom relativ stark entfeuchtet, wobei der Grad der Entfeuchtung um so größer ist, je niedriger die an dem Verdampfer realisierte Temperatur ist. Aufgrund der vorgenannten Tatsache kommt es zu einer Eis- bzw. Schneebildung an dem Verdampfer bzw. den Verdampferlamellen. Der Vorteil dieser Verfahrensweise liegt darin, dass die relative Luftfeuchtigkeit über die Zeit im Wesentlichen konstant bleibt, jedoch einen nur vergleichsweise geringen Wert erreicht. Wird der Verdampfer hingegen zyklisch betrieben, so variiert die relative Luftfeuchtigkeit relativ stark, da die Kühlluft lediglich bei eingeschaltetem Verdampfer entfeuchtet wird. Bei dieser Verfahrensweise schwanken die Werte der relativen Feuchtigkeit im Auslassbereich des Zuluftkanales üblicherweise zwischen 60 und 85 %.If the evaporator is operated continuously, the circulating in the furniture (Cool) airflow dehumidified relatively strongly, the degree of dehumidification all the more is greater, the lower the temperature realized on the evaporator. Due to the the aforementioned fact results in ice or snow formation on the Evaporator or the evaporator fins. The advantage of this procedure is in that the relative humidity remains essentially constant over time, however reached a comparatively low value. Will the evaporator on the other hand, operated cyclically, the relative air humidity varies relatively strongly, since the Cooling air is dehumidified only when the evaporator is switched on. At this The relative humidity values in the outlet area fluctuate of the supply air duct usually between 60 and 85%.

Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Warenpräsentationsmöbel anzugeben, in dem eine Erhöhung der durchschnittlichen relativen Luftfeuchtigkeit in dem Möbel bzw. dessen Warenraum und/oder Warenauslageböden realisiert werden kann.The object of the present invention is a generic Goods display furniture indicate an increase in the average relative humidity in the furniture or its goods room and / or Goods display shelves can be realized.

Dieser zusätzliche Kältemittel(gemisch)kreislauf weist nun wenigstens einen Wärmetauscher auf, der derart angeordnet ist, dass der in dem Verdampfer oder dem Wärmetauscher des Warenpräsentationsmöbels erzeugte Kühlluftstrom zumindest teilweise durch diesen Wärmetauscher des separaten Kältemittel(gemisch)kreislaufes geführt wird. Dadurch wird erreicht, dass das in dem separaten Kältemittel(gemisch)kreislauf zirkulierende Kältemittel oder Kältemittelgemisch abgekühlt wird. Unter dem Begriff "Kältemittel" sei nachfolgend auch immer ein Kältemittelgemisch zu verstehen.According to the invention, at least one additional separate, closed one is now Refrigerant (mixture) circuit provided with which contact cooling of the or Goods display shelves and / or goods rooms is realized. This additional Refrigerant (mixed) circuit now has at least one heat exchanger, the is arranged such that the in the evaporator or the heat exchanger Goods display furniture generated cooling air flow at least partially through this Heat exchanger of the separate refrigerant (mixed) circuit is performed. Thereby it is achieved that the circulating in the separate refrigerant (mixture) circuit Refrigerant or refrigerant mixture is cooled. Under the term "refrigerant" always to understand a refrigerant mixture below.

Als Kältemittel kommt vorzugsweise ein Gemisch bestehend aus Wasser und Glykol zur Anwendung. Die Zirkulation des Kältemittels in diesem Kältemittel(gemisch)kreislauf wird durch die in ihm herrschende Temperaturdifferenz erreicht, so dass weder Pumpen noch Verdichter erforderlich sind. Aufgrund der Kontaktkühlung wird eine ausreichende Kühlung der präsentierten Waren erzielt, ohne dass diese jedoch - wie dies bei einem zirkulierenden Kühlluftstrom der Fall ist - entfeuchtet werden. Die angebotenen Waren können somit über einen längeren Zeitraum in einem optisch ansprechenden Zustand präsentiert werden, woraus eine Erhöhung des Warenabsatzes resultiert.A mixture consisting of water and glycol is preferably used as the refrigerant to use. The circulation of the refrigerant in this The refrigerant (mixed) circuit is characterized by the temperature difference in it reached so that neither pumps nor compressors are required. Due to the Adequate cooling of the presented goods is achieved without contact cooling but that - as is the case with a circulating cooling air flow - be dehumidified. The goods offered can therefore last longer Period are presented in a visually appealing state, from which a This increases the sales of goods.

Diese Ausgestaltung des erfindungsgemäßen Warenpräsentationsmöbel stellt einen Kompromiss zwischen dem vorbeschriebenen Stand der Technik und der vorliegenden Erfindung dar. Nachdem sich das in dem zusätzlichen Kältemittel(gemisch)kreislauf zirkulierende Kältemittel auf seinem Weg durch den Kältemittel(gemisch)kreislauf abkühlt, gibt es zwangsläufig Bereiche auf dem Warenauslageboden bzw. in dem Warenraum, die weniger stark und u. U. nicht ausreichend gekühlt werden. Um auch in diesen Bereichen die erforderliche Kühlung der angebotenen Waren realisieren zu können, ist es daher ggf. erforderlich, diesen Bereichen Kühlluft zuzuführen. This embodiment of the product presentation furniture according to the invention represents one Compromise between the state of the art described above and the present one Invention represents. After that in the additional refrigerant (mixture) circuit circulating refrigerant on its way through the refrigerant (mixed) cycle cools down, there are inevitably areas on the goods display floor or in the Goods room that is less strong and u. May not be adequately cooled. To also in realize the necessary cooling of the goods offered in these areas , it may be necessary to supply cooling air to these areas.
