Definitions
- a refrigerated cabinet having at least one cold room with a bottom tray for receiving and storing refrigerated goods and a heat exchanger.
- Refrigerated counters are used, for example, in the food retail trade to offer sausage and meat products, fruits and vegetables and dairy products.
- the cold room which can also be referred to as a goods room, open at the top.
- refrigerated counters with a closable goods room which are stored in such refrigerated counters usually frozen products.
- Foods stored in refrigerated counters are subject to the legally prescribed food temperatures. In order to bring the food to the desired temperatures, air is passed through heat exchangers and the cooled air is passed over the food.
- Conventional refrigerated counters from the State of the art have a heat exchanger, which is arranged in the rear wall of the refrigerated display case or below a goods display floor.
- the heat exchanger is designed as a ribbed tube bundle heat exchanger.
- the cooling fins of the tube bundle heat exchanger are arranged directly on the tubes and are cooled by a guided through the tubes coolant. Air is passed over the cooling fins and thereby cooled.
- For air circulation fans are provided, which are usually arranged in the immediate vicinity of the cooling fins.
- the refrigerated counter and its components must be cleaned at regular intervals.
- the cleaning involves washing out the bottom pan of a refrigerated counter and the merchandising shelves that are hung above the floor pan in a cold room of the refrigerated counter.
- the heat exchanger must be cleaned at certain intervals. Since the heat exchanger is usually located in the rear wall of the refrigerated counter or below the goods shelves, this is difficult to reach and clean. To get to the heat exchanger and to clean it is therefore often necessary to dismantle parts of the refrigerated display.
- fans for circulating air in a refrigerated counter often obstruct thorough and rapid cleaning of the interior of the refrigerated counter.
- the fans must be folded up or even disassembled for cleaning.
- the object is to provide a refrigerator, which overcomes the problems of the prior art and allows easy and quick cleaning of a cabinet.
- the heat transfer unit is arranged separately from the fluid line arrangement and easily removed from the refrigerated cabinets. As a result, the cleaning of the cabinet is significantly improved. It is not necessary to disassemble parts or, for example, to fold up fans. Depending on the size of the at least one heat transfer unit, this can, for example, be made for cleaning in a dishwasher.
- the heat exchangers are arranged either in a rear wall or under or on a floor pan.
- the cleaning is therefore very expensive.

- the air ducts are formed both via the hollow profile body itself and between adjacently arranged hollow profile bodies, the element connecting the hollow profile body and the floor pan on which the at least one heat transfer unit, ie the hollow profile bodies, rest.
- the hollow profile body may have different profile shapes. For example. have the hollow profile body round or square profiles. Square, particularly rectangular (e.g., square) profile shapes are advantageous because there is a relatively large contact area for contact with the floor pan. Via the contact surface, the heat transfer or the cooling takes place through the fluid or coolant guided in the fluid lines of the fluid line arrangement.
- the fluid conduits may also have different cross-sectional shapes. The fluid conduits may be in direct contact with the tray or spaced from the tray, with a thermally conductive material (solid or gas) interposed therebetween.
- the element connecting the heat transfer elements may be a plate, the plate being a merchandising shelf can, which connects the heat transfer elements together.
- the at least one heat transfer unit can have a high thermal conductivity, so that an efficient cooling of the heat transfer elements and the air guided over it is achieved.
- the at least one heat transfer unit may consist of a metal or a metal alloy.
- the heat transfer unit is made of aluminum or an aluminum alloy, it has a high thermal conductivity.
- aluminum and aluminum alloys are advantageous for use in refrigerated food because of their antibacterial effect. In addition to aluminum but also other metals own.
- the at least one heat transfer unit can have a goods display surface or the element connecting the heat transfer elements can be designed as a goods display surface.
- the goods display shelves for the food are formed by the at least one heat transfer unit or are part of the at least one heat transfer unit.
- a contact cooling for the food can be done. As a rule, the food is cooled by the cooled air.
- the floor pan may have support areas for the at least one heat transfer unit and, on the other hand, lower drainage areas for liquids. This facilitates drainage of liquids. For example, a cleaning fluid just drain. Likewise, liquids derived from food can easily drain off.
- the cooling furniture may have at least one fan for circulating the air via the at least one heat transfer unit, a conveying device for circulating a fluid guided in the fluid line arrangement and / or a cooling unit.
- the fluid for example.
- a coolant can be cooled.
- the refrigerator can be operated alone in such versions.
- the cooling furniture is connected via corresponding connections to a fluid system, via which, for example, a coolant is supplied, which is brought from a central cooling device to a determinable coolant temperature.
- the conveyor may be, for example, a variable speed pump or a compressor and an expansion valve.
- the pump controls the amount of coolant or fluid which is passed through the fluid line arrangement.
- the cooling capacity of the cabinet can be controlled depending on the delivered amount of fluid or coolant.
- the at least one fan may be arranged in further embodiments in a rear wall of the cooling cabinet and extend the bottom tray and the at least one heat transfer element at least partially up to the rear wall.
- the speed of the fan may be controllable, so that the amount of circulated air can be changed.
- the speed of fans and the speed of the pump can be increased or the expansion valve can be opened, so that a fast Cooling is achieved.
- the information about this can be derived, for example, via sensors or other detection devices and determined by a controller.
- the controller determines a cooling demand and, if necessary, causes a change in the speed of the at least one fan and the speed-controlled pump.

- the heat transfer unit 32 can be placed in a dishwasher, depending on its size, for example, and thereby cleaned. In contrast to prior art refrigeration units, no parts need to be removed for cleaning the refrigerated cabinet 10. Also, the heat exchanger, in this case the heat transfer unit 32, can be easily cleaned. This is not possible in the prior art, since the heat exchanger is usually installed directly with the coolant lines 18. Cleaning is therefore very expensive in the prior art.
- a refrigeration cabinet 10 may include other components suitable for the in Fig. 1 embodiment shown and for in Fig. 2 embodiment shown are not shown. These include not exhaustive temperature detection devices, detection devices for the flow rate and amount of circulating air and the refrigerant or a refrigerant, power supply units, sealing elements, drainage systems for water, pipe systems for liquids (eg cooling or refrigerant), valves, and further Connections and insulation materials.
- a refrigeration unit 10 may also have closure elements for closing the goods compartment 12. These can be designed as a sliding cover. It is also possible to arrange glass attachments on a customer side of the refrigerated cabinet 10, which both serve as merchandise protection and also influence the airflow in the goods compartment 12.
- Fig. 2 shows a schematic side view of a cooling counter designed as a refrigerated cabinet 10 in a second embodiment.
- the second embodiment of a refrigerated cabinet 10 differs from the first embodiment in that the bottom pan 16 extends below the rear wall 50. Accordingly, the coolant lines 18 also extend below the rear wall 50.
- the heat transfer unit 32 has a size such that it likewise protrudes into the rear wall 50. The guided over the air channels 48 air can thereby rise directly into the section 40 upwards and is circulated through the at least one fan 34. In this embodiment, the section 40 can be cleaned more easily.

Description
Es wird ein Kühlmöbel beschrieben, das mindestens einen Kühlraum mit einer Bodenwanne zur Aufnahme und Lagerung von Kühlgut und einen Wärmeübertrager aufweist.It is described a refrigerated cabinet having at least one cold room with a bottom tray for receiving and storing refrigerated goods and a heat exchanger.
Derartige Kühlmöbel sind bspw. als Kühltheken bekannt. Kühltheken werden zum Beispiel im Lebensmitteleinzelhandel verwendet, um Wurst- und Fleischwaren, Obst und Gemüse sowie Milchprodukte anzubieten. Bei solchen Kühltheken ist der Kühlraum, der auch als Warenraum bezeichnet werden kann, oben hin offen. Es gibt auch Kühltheken mit einem schließbaren Warenraum, wobei in solchen Kühltheken in der Regel tiefgefrorene Produkte gelagert werden.Such refrigeration units are known, for example, as refrigerated counters. Refrigerated counters are used, for example, in the food retail trade to offer sausage and meat products, fruits and vegetables and dairy products. In such refrigerated counters, the cold room, which can also be referred to as a goods room, open at the top. There are also refrigerated counters with a closable goods room, which are stored in such refrigerated counters usually frozen products.
Für die in Kühltheken aufgenommenen Lebensmittel gelten gesetzlich vorgeschriebene Lebensmitteltemperaturen. Um die Lebensmittel auf die gewünschte Temperaturen zu bringen wird Luft über Wärmeübertrager geleitet und die gekühlte Luft über die Lebensmittel geführt. Konventionelle Kühltheken aus dem Stand der Technik weisen einen Wärmeübertrager auf, der in der Rückwand der Kühltheke oder unterhalb eines Warenauslagebodens angeordnet ist. Beispielsweise ist der Wärmeübertrager als berippter Rohrbündelwärmeübertrager ausgebildet. Die Kühlrippen des Rohrbündelwärmeübertragers sind direkt an den Rohren angeordnet und werden über ein durch die Rohre geführtes Kühlmittel gekühlt. Luft wird über die Kühlrippen geleitet und dadurch gekühlt. Zur Luftumwälzung sind Ventilatoren vorgesehen, die in der Regel in unmittelbarer Nähe der Kühlrippen angeordnet sind.Foods stored in refrigerated counters are subject to the legally prescribed food temperatures. In order to bring the food to the desired temperatures, air is passed through heat exchangers and the cooled air is passed over the food. Conventional refrigerated counters from the State of the art have a heat exchanger, which is arranged in the rear wall of the refrigerated display case or below a goods display floor. For example, the heat exchanger is designed as a ribbed tube bundle heat exchanger. The cooling fins of the tube bundle heat exchanger are arranged directly on the tubes and are cooled by a guided through the tubes coolant. Air is passed over the cooling fins and thereby cooled. For air circulation fans are provided, which are usually arranged in the immediate vicinity of the cooling fins.
Zur Einhaltung von Hygienevorschriften müssen die Kühltheke und deren Komponenten in regelmäßigen Abständen gereinigt werden. Die Reinigung beinhaltet ein Auswaschen der Bodenwanne einer Kühltheke und der Warenauslegeböden, die über der Bodenwanne in einem Kühlraum der Kühltheke eingehängt sind. In bestimmten Abständen muss zusätzlich der Wärmeübertrager gereinigt werden. Da der Wärmeübertrager in der Regel in der Rückwand der Kühltheke oder unterhalb den Warenauslegeböden angeordnet ist, ist dieser nur schwer erreichbar und zu reinigen. Um an den Wärmeübertrager zu gelangen und ihn zu reinigen ist es deshalb häufig notwendig, Teile der Kühltheke zu demontieren.To comply with hygiene regulations, the refrigerated counter and its components must be cleaned at regular intervals. The cleaning involves washing out the bottom pan of a refrigerated counter and the merchandising shelves that are hung above the floor pan in a cold room of the refrigerated counter. In addition, the heat exchanger must be cleaned at certain intervals. Since the heat exchanger is usually located in the rear wall of the refrigerated counter or below the goods shelves, this is difficult to reach and clean. To get to the heat exchanger and to clean it is therefore often necessary to dismantle parts of the refrigerated display.
Darüber hinaus behindern oftmals Ventilatoren zur Umwälzung der Luft in einer Kühltheke eine gründliche und schnelle Reinigung des Innenraums der Kühltheke. Die Ventilatoren müssen hochgeklappt oder sogar demontiert werden, um eine Reinigung durchführen zu können.In addition, fans for circulating air in a refrigerated counter often obstruct thorough and rapid cleaning of the interior of the refrigerated counter. The fans must be folded up or even disassembled for cleaning.
Demgegenüber besteht die Aufgabe ein Kühlmöbel anzugeben, welches die Probleme des Stands der Technik behebt und eine einfache und schnelle Reinigung eines Kühlmöbels erlaubt.In contrast, the object is to provide a refrigerator, which overcomes the problems of the prior art and allows easy and quick cleaning of a cabinet.
Die Aufgabe wird durch ein Kühlmöbel mit den in Anspruch 1 angegebenen technischen Merkmalen gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen im Detail angegeben.The object is achieved by a refrigerated cabinet with the technical features specified in claim 1. Advantageous developments are specified in the dependent claims in detail.
Ein Kühlmöbel, das die vorstehend genannte Aufgabe löst, weist mindestens einen Kühlraum zur Aufnahme und Lagerung von Kühlgut und einen Wärmeübertrager auf, wobei der Kühlraum eine Bodenwanne aufweist, und wobei
- unter der Bodenwanne eine Fluidleitungsanordnung angeordnet ist,
- auf der Bodenwanne mindestens eine Wärmeübertragungseinheit aufliegt,
- die mindestens eine Wärmeübertragungseinheit eine Vielzahl von Wärmeübertragungselementen aufweist, die mit der Bodenwanne in Kontakt stehen und Luftkanäle ausbilden, und
- die mindestens eine Wärmeübertragungseinheit entnehmbar ist.
- a fluid line arrangement is arranged below the floor pan,
- at least one heat transfer unit rests on the floor pan,
- the at least one heat transfer unit has a plurality of heat transfer elements in contact with the floor pan and forming air passages, and
- the at least one heat transfer unit can be removed.
Bei dem Kühlmöbel ist die Wärmeübertragungseinheit getrennt von der Fluidleitungsanordnung angeordnet und aus dem Kühlmöbel einfach entnehmbar. Dadurch wird die Reinigung des Kühlmöbels wesentlich verbessert. Es ist nicht notwendig Teile zu demontieren oder bspw. Ventilatoren hochzuklappen. Je nach Größe der mindestens einen Wärmeübertragungseinheit kann diese bspw. zur Reinigung in eine Spülmaschine gestellt werden.In the refrigerator, the heat transfer unit is arranged separately from the fluid line arrangement and easily removed from the refrigerated cabinets. As a result, the cleaning of the cabinet is significantly improved. It is not necessary to disassemble parts or, for example, to fold up fans. Depending on the size of the at least one heat transfer unit, this can, for example, be made for cleaning in a dishwasher.
Bei herkömmlichen Kühlmöbeln aus dem Stand der Technik sind die Wärmeübertrager entweder in einer Rückwand oder unter bzw. an einer Bodenwanne angeordnet. Die Reinigung ist deswegen sehr aufwendig. Bei dem hierin beschriebenen Kühlmöbel wird zur Reinigung die mindestens eine Wärmeübertragungseinheit entnommen, wodurch die Bodenwanne frei zugänglich ist und zusätzlich die mindestens eine Wärmeübertragungseinheit selbst gereinigt werden kann. Bei dem hierin beschriebenen Kühlmöbel wird die "kalte Oberfläche" (Bodenwanne, Fluidleitungsanordnung) von der "Berippung" (Luftkanäle, Wärmeübertragungselemente) getrennt.In conventional refrigeration units of the prior art, the heat exchangers are arranged either in a rear wall or under or on a floor pan. The cleaning is therefore very expensive. In the cooling furniture described herein, the at least one heat transfer unit is removed for cleaning, whereby the floor pan is freely accessible and in addition the at least one heat transfer unit itself can be cleaned. In the refrigeration furniture described herein, the "cold surface" (bottom pan, fluid conduit assembly) is separated from the "ribbing" (air channels, heat transfer elements).
Die Wärmeübertragungseinheit kann zugleich als Warenauslageboden dienen, auf den das zu kühlende Kühlgut aufgelegt wird. Hierzu kann die Wärmeübertragungseinheit eine entsprechend ausgebildete Oberfläche aufweisen.The heat transfer unit can also serve as a merchandise display shelf on which the refrigerated goods to be cooled is placed. For this purpose, the heat transfer unit may have a correspondingly formed surface.
Bei dem hierin beschriebenen Kühlmöbel wird Luft bspw. über einen Lüfter (z.B. Ventilator) umgewälzt, wobei die Luft entlang der Luftkanäle der Wärmeübertragungselemente der mindestens einen Wärmeübertragungseinheit bzw. durch Warenauslegeböden geleitet wird. Die Wärmeübertragungselemente der mindestens einen Wärmeübertragungseinheit stehen mit der Bodenwanne zumindest abschnittsweise in thermisch leitenden Kontakt. Über die Fluidleitungsanordnung wird ein Kühlmittel geführt, was zu einer Kühlung der Bodenwanne und damit auch zu einer Kühlung der mindestens einen Wärmeübertragungseinheit führt.For example, in the refrigeration furniture described herein, air is circulated through a fan (e.g., fan), the air being directed along the air passages of the heat transfer elements of the at least one heat transfer unit or through merchandise shelves. The heat transfer elements of the at least one heat transfer unit are at least partially in thermally conductive contact with the bottom trough. A coolant is guided via the fluid line arrangement, which leads to cooling of the base trough and thus also to cooling of the at least one heat transfer unit.
Die Ausbildung der Wärmeübertragungselemente zur Bildung von Luftkanälen kann unterschiedlich sein. Beispielsweise können die Wärmeübertragungselemente Hohlprofilkörper und/oder Kühlrippen sein.The formation of the heat transfer elements to form air channels may be different. For example, you can the heat transfer elements be hollow profile body and / or cooling fins.
Die mindestens eine Wärmeübertragungseinheit kann ferner ein die Wärmeübertragungselemente verbindendes Element aufweisen. Bspw. werden dabei zwischen den Kühlrippen, dem die Kühlrippen verbindenden Element und der Bodenwanne, auf der die mindestens eine Wärmeübertragungseinheit, also die Kühlrippen, aufliegen, die Luftkanäle gebildet. Bei Ausführungen in welchen die Wärmeübertragungselemente Hohlprofilkörper sind, werden sowohl über die Hohlprofilkörper selbst als auch zwischen benachbart angeordneten Hohlprofilköpern, dem die Hohlprofilkörper verbindenden Element und der Bodenwanne, auf der die mindestens eine Wärmeübertragungseinheit, also die Hohlprofilköper, aufliegen, die Luftkanäle gebildet.The at least one heat transfer unit may further comprise an element connecting the heat transfer elements. For example. In this case, the air ducts are formed between the cooling fins, the element connecting the cooling fins and the base trough, on which the at least one heat transfer unit, ie the cooling fins, rest. In embodiments in which the heat transfer elements are hollow profile bodies, the air ducts are formed both via the hollow profile body itself and between adjacently arranged hollow profile bodies, the element connecting the hollow profile body and the floor pan on which the at least one heat transfer unit, ie the hollow profile bodies, rest.
Die Hohlprofilkörper können verschiedene Profilformen aufweisen. Bspw. weisen die Hohlprofilkörper runde oder eckige Profile auf. Eckige, insbesondere rechteckige (z.B. quadratische) Profilformen sind vorteilhaft, da eine relativ große Kontaktfläche für den Kontakt mit der Bodenwanne besteht. Über die Kontaktfläche erfolgt der Wärmeübergang bzw. die Kühlung durch das in den Fluidleitungen der Fluidleitungsanordnung geführte Fluid bzw. Kühlmittel. Die Fluidleitungen können ebenfalls verschiedenen Querschnittsformen aufweisen. Die Fluidleitungen können direkt mit der Bodenwanne in Kontakt stehen oder beabstandet zu der Bodenwanne angeordnet sein, wobei dazwischen ein wärmeleitfähiges Material (Festkörper oder Gas) vorgesehen sein kann.The hollow profile body may have different profile shapes. For example. have the hollow profile body round or square profiles. Square, particularly rectangular (e.g., square) profile shapes are advantageous because there is a relatively large contact area for contact with the floor pan. Via the contact surface, the heat transfer or the cooling takes place through the fluid or coolant guided in the fluid lines of the fluid line arrangement. The fluid conduits may also have different cross-sectional shapes. The fluid conduits may be in direct contact with the tray or spaced from the tray, with a thermally conductive material (solid or gas) interposed therebetween.
Das die Wärmeübertragungselemente verbindende Element kann eine Platte sein, wobei die Platte ein Warenauslageboden sein kann, der die Wärmeübertragungselemente miteinander verbindet.The element connecting the heat transfer elements may be a plate, the plate being a merchandising shelf can, which connects the heat transfer elements together.
Die mindestens eine Wärmeübertragungseinheit kann eine hohe thermische Leitfähigkeit aufweisen, damit eine effiziente Kühlung der Wärmeübertragungselemente und der darüber geführten Luft erreicht wird.The at least one heat transfer unit can have a high thermal conductivity, so that an efficient cooling of the heat transfer elements and the air guided over it is achieved.
In weiteren Ausführungen kann die mindestens eine Wärmeübertragungseinheit aus einem Metall oder einer Metalllegierung bestehen. Bspw. besteht die Wärmeübertragungseinheit aus Aluminium oder einer Aluminiumlegierung und weist dadurch eine hohe Wärmeleitfähigkeit auf. Darüber hinaus sind Aluminium und Aluminiumlegierungen für den Einsatz in Kühlmöbeln für Lebensmittel aufgrund ihrer antibakteriellen Wirkung vorteilhaft. Neben Aluminium eigenen sich aber auch andere Metalle.In further embodiments, the at least one heat transfer unit may consist of a metal or a metal alloy. For example. If the heat transfer unit is made of aluminum or an aluminum alloy, it has a high thermal conductivity. In addition, aluminum and aluminum alloys are advantageous for use in refrigerated food because of their antibacterial effect. In addition to aluminum but also other metals own.
Die mindestens eine Wärmeübertragungseinheit kann eine Warenauslagefläche aufweisen oder das die Wärmeübertragungselemente verbindende Element kann als Warenauslagefläche ausgebildet sein. In diesen Ausführungen werden die Warenauslageböden für die Lebensmittel durch die mindestens eine Wärmeübertragungseinheit gebildet oder sind Bestandteil der mindestens einen Wärmeübertragungseinheit. In solchen Ausführungen kann eine Kontaktkühlung für die Lebensmittel erfolgen. In der Regel werden die Lebensmittel über die gekühlte Luft gekühlt.The at least one heat transfer unit can have a goods display surface or the element connecting the heat transfer elements can be designed as a goods display surface. In these embodiments, the goods display shelves for the food are formed by the at least one heat transfer unit or are part of the at least one heat transfer unit. In such embodiments, a contact cooling for the food can be done. As a rule, the food is cooled by the cooled air.
Die Bodenwanne kann Auflagebereiche für die mindestens eine Wärmeübertragungseinheit und demgegenüber tieferliegende Ablaufbereiche für Flüssigkeiten aufweisen. Dadurch wird ein Ablaufen von Flüssigkeiten erleichtert. Z.B. kann eine Reinigungsflüssigkeit einfach abfließen. Ebenso können auch Flüssigkeiten, die von Lebensmitteln stammen, einfach abfließen.The floor pan may have support areas for the at least one heat transfer unit and, on the other hand, lower drainage areas for liquids. This facilitates drainage of liquids. For example, a cleaning fluid just drain. Likewise, liquids derived from food can easily drain off.
Das Kühlmöbel kann mindestens einen Ventilator zur Umwälzung der Luft über die mindestens eine Wärmeübertragungseinheit, eine Fördereinrichtung zur Umwälzung eines in der Fluidleitungsanordnung geführten Fluids und/oder ein Kälteaggregat aufweisen. Über das Kälteaggregat kann das Fluid, bspw. ein Kühlmittel, gekühlt werden. Das Kühlmöbel kann in solchen Ausführungen alleine betrieben werden. In weiteren Ausführungen ist das Kühlmöbel über entsprechende Anschlüsse an ein Fluidsystem angeschlossen, über welches bspw. ein Kühlmittel zugeführt wird, welches von einer zentralen Kühleinrichtung auf eine bestimmbare Kühlmitteltemperatur gebracht wird.The cooling furniture may have at least one fan for circulating the air via the at least one heat transfer unit, a conveying device for circulating a fluid guided in the fluid line arrangement and / or a cooling unit. About the refrigeration unit, the fluid, for example. A coolant can be cooled. The refrigerator can be operated alone in such versions. In further embodiments, the cooling furniture is connected via corresponding connections to a fluid system, via which, for example, a coolant is supplied, which is brought from a central cooling device to a determinable coolant temperature.
Die Fördereinrichtung kann bspw. eine drehzahlgeregelte Pumpe oder ein Kompressor und ein Expansionsventil sein. Die Pumpe regelt die Menge an Kühlmittel bzw. Fluid, welches durch die Fluidleitungsanordnung geführt wird. Über die drehzahlgeregelte Pumpe kann in Abhängigkeit der geförderten Menge an Fluid bzw. Kühlmittel die Kühlleistung des Kühlmöbels geregelt werden.The conveyor may be, for example, a variable speed pump or a compressor and an expansion valve. The pump controls the amount of coolant or fluid which is passed through the fluid line arrangement. About the speed-controlled pump, the cooling capacity of the cabinet can be controlled depending on the delivered amount of fluid or coolant.
Der mindestens eine Ventilator kann in weiteren Ausführungsformen in einer Rückwand des Kühlmöbels angeordnet sein und sich die Bodenwanne und das mindestens eine Wärmeübertragungselement mindestens abschnittsweise bis in die Rückwand erstrecken. Die Drehzahl des Ventilators kann regelbar sein, so dass die Menge an umgewälzter Luft verändert werden kann. Bei einem Einbringen von neuen Waren können bspw. die Drehzahl von Ventilatoren und die Drehzahl der Pumpe erhöht bzw. das Expansionsventil geöffnet werden, damit eine schnelle Kühlung erreicht wird. Die Informationen hierüber können bspw. über Sensoren oder andere Erfassungseinrichtungen abgeleitet und durch eine Steuerung ermittelt werden. Die Steuerung ermittelt einen Kühlbedarf und veranlasst gegebenenfalls eine Änderung der Drehzahl des mindestens einen Ventilators und der drehzahlgeregelten Pumpe.The at least one fan may be arranged in further embodiments in a rear wall of the cooling cabinet and extend the bottom tray and the at least one heat transfer element at least partially up to the rear wall. The speed of the fan may be controllable, so that the amount of circulated air can be changed. When introducing new goods, for example, the speed of fans and the speed of the pump can be increased or the expansion valve can be opened, so that a fast Cooling is achieved. The information about this can be derived, for example, via sensors or other detection devices and determined by a controller. The controller determines a cooling demand and, if necessary, causes a change in the speed of the at least one fan and the speed-controlled pump.

Das Kühlmöbel 10 weist eine Rückwand 50 auf, in der mindestens ein Ventilator 34 angeordnet ist. Ferner weist das Kühlmöbel 10 Anschlüsse 26 auf, von denen aus sich Versorgungsleitungen 28 zu Kühlmittelleitungen 18 erstrecken. Die Versorgungsleitungen 28 dienen zur Zufuhr eines Kühlmittels. Hierzu ist das Kühlmöbel 10 über die Anschlüsse 26 mit einem zentralen Versorgungsnetz für das Kühlmittel verbunden. An das Versorgungsnetz können eine Vielzahl von Kühlmöbel 10 und weitere Einrichtungen angeschlossen sein. Beispielsweise wird die Kühlung des Kühlmittels über eine Wärmepumpenanordnung bereitgestellt.The
Die Anschlüsse 26 können auch Mittel für eine Energieversorgung aufweisen, über welche beispielsweise das Kühlmöbel 10 mit Strom versorgt wird. Das Kühlmöbel 10 weist eine Steuereinheit 22 auf, die den Betrieb des Kühlmöbels 10 steuert bzw. regelt. Über die Steuereinheit 22 wird die Kühlung des Warenraums 12 in Abhängigkeit von einstellbaren Werten, gemessenen Informationen und weiteren Parametern geregelt.The
In alternativen Ausführungsformen kann das Kühlmöbel 10 ein Kälteaggregat 24 aufweisen, über welches das in Kühlmittelleitungen 18 geführte Kühlmittel gekühlt wird. In einer solchen Ausführungsform ist das Kühlmöbel 10 nicht an ein Kühlmittelversorgungsnetz angeschlossen.In alternative embodiments, the
In einem Vorlauf der Versorgungsleitungen 18 ist eine drehzahlgeregelte Pumpe 20 angeordnet, die zur Zufuhr von Kühlmittel zu den Kühlmittelleitungen 18 vorgesehen ist. Die Kühlmittelleitungen 18 strecken sich unterhalb einer Bodenwanne 16. Die Kühlmittelleitungen 18 verlaufen insbesondere so, dass die gesamte Bodenwanne 16 gekühlt wird. Die Fläche der Bodenwanne 16 und die Fläche, welche von den Kühlmittelleitungen 18 abgedeckt wird, können gleich groß sein.In a flow of the

Zum Reinigen des Kühlmöbels 10 muss lediglich die mindestens eine Wärmeübertragungseinheit 32 entnommen werden. Anschließend können die Wärmeübertragungseinheit 32 und die Bodenwanne 16 einfach gereinigt werden. Die Bodenwanne 16 weist gegenüber bekannten Kühlmöbeln keine Kühlstruktur (z.B. an der Bodenwanne 16 angeordnete Kühlrippen) auf, so dass ein einfaches Reinigen möglich ist. Es können lediglich Ablaufstrukturen zum Abfließen von Wasser oder der Reinigungsflüssigkeit, sowie ein Abfluss vorgesehen sein. Kühlrippen oder ähnliches sind in oder an der Bodenwanne 16 nicht vorgesehen. Die Wärmeübertragungseinheit 32 kann in Abhängigkeit ihrer Größe beispielsweise in eine Spülmaschine gestellt und dabei gereinigt werden. Im Gegensatz zu Kühlmöbeln aus dem Stand der Technik müssen zum Reinigen des Kühlmöbels 10 keine Teile abmontiert werden. Auch der Wärmeübertrager, in diesem Fall die Wärmeübertragungseinheit 32, können einfach gereinigt werden. Dies ist im Stand der Technik nicht möglich, da in der Regel der Wärmeübertrager direkt mit den Kühlmittelleitungen 18 verbaut ist. Eine Reinigung ist daher im Stand der Technik sehr aufwendig.For cleaning the cooling
