Definitions
- the present invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, according to the preamble of claim 1.
- Such a refrigerator is from the utility model DE 20 2004 021 113 U1 known.
- This known refrigeration device has a compressor, a connected to an output of the compressor high pressure area and connected to an input of the compressor low pressure area and a collecting container for emerging from an interior condensate, wherein in the high pressure area a thermally coupled to the receptacle heat exchanger is incorporated.
- the heat exchanger comprises a pipe through which a refrigerant flows, which pipe is either immersed in the collecting container or integrated into a side wall of the collecting container.
- the object of the invention is therefore to provide a refrigeration device with condensation water tank, in which the evaporation of the condensation water is ensured even more efficient.
- the object is achieved with a refrigerator with the features of claim 1.
- the invention is based on the insight that the evaporation coldness of the defrosting water in the condensation water tank lowers the condenser temperature.
- the invention has the surprising effect of not only supplying no additional energy must be to evaporate condensate, but even the energy consumption of the refrigerator is reduced.
- the collecting container ie condensation water tank
- the collecting container ie condensation water tank
- the collecting container surprisingly also reduces the energy consumption when the condensation water tank is empty, because, for example, the condensation or condensed water has already completely evaporated. This is ensured by the fact that the good thermal conductivity of the collecting container causes heat to be radiated from the dry collecting container.
- a good thermal conductivity of the collecting container is understood as meaning a thermal conductivity of from 1 to 200 W / mK, in particular from 10 to 100 W / mK .
- the guidance of the pipe section of the condenser tube within at least one wall of the condensation water container protects the pipe section from corrosion.
- the heat-conducting material of the condensation water tank which can also be referred to as an evaporation tank, selected from the group consisting of aluminum, Al-Mg alloy, graphite and highly thermally conductive plastics.
- an evaporation tank selected from the group consisting of aluminum, Al-Mg alloy, graphite and highly thermally conductive plastics.
- all other materials high heat conduction suitable for the formation of the walls of the condensation water which also ensure a long life of the condensation water with regard to corrosion and thermal expansion coefficient.
- highly heat-conductive plastic this is preferably from the group of plastics provided with fillers, such as graphite powder, metal powder, in particular aluminum and copper or oriented carbon fibers, such as polypropylene, polystyrene or polyethylene.
- fillers such as graphite powder, metal powder, in particular aluminum and copper or oriented carbon fibers, such as polypropylene, polystyrene or polyethylene.
- Such highly heat-conducting plastics are known, for example, under the trade name CooIPoly from Intratron or under the trade name "Omegabond ( www.omega.de )."
- CooIPoly from Intratron
- Omegabond www.omega.de
- the pipe section is guided through at least one side wall and / or a bottom wall of the evaporation tank.
- This further increases the efficiency with which the evaporative cooling of the condensation water cools a refrigerant in the condenser tube.
- the arrangement of the pipe section in the bottom wall ensures a high heat transfer rate from the pipe section to the condensation, since the condensation is located directly above the bottom wall.
- the pipe section is guided in a meandering manner in the at least one wall. This increases the total distance that covers the pipe section in the condensation water tank and thus the heat transfer. The reduction of energy consumption is so high.
- the wall thickness of the container is at least in places larger than 0.3 mm, in particular greater than 0.5 mm, preferably between 0.3 and 5 mm, particularly preferably between 2 and 3 mm.
- This large thickness causes a high heat capacity of the walls, whereby the refrigerant can be withdrawn a lot of heat. This is especially the case when the condensation water tank is dry after evaporation of the condensation water.
- the pipe section is poured into the walls, sprayed, pressed or glued.
- a particularly intimate connection of the pipe section is achieved with the walls. This results in a particularly good heat transfer.
- a forced ventilation such as by a fan, is provided in the vicinity of the condensation water container, which causes an air flow to be moved via the condensation water container.
- This increases the evaporation rate of the dew water and thus increases the evaporation cold through the evaporating condensate.
- a particularly efficient cooling of the refrigerant in the condenser tube is achieved by removing warm air in the immediate vicinity of the condensation water tank. This is especially because of the combination with the good Thermal conductivity of the material of the walls of the case.
- the use of forced ventilation is particularly advantageous when the refrigerator already has an outdoor fan, so that no additional energy consumption is incurred to operate the forced ventilation.
- Fig. 1 shows a schematic section through a section of a refrigerator according to the invention with evaporation tank.
- the inventive refrigeration device 1 according to a in Fig. 1 shown embodiment includes cooled interior 2, which is surrounded by a heat-insulating housing 3.
- a collecting groove 5 is formed, from which a at the lowest point of the collecting groove 5 connected Abtauwassertechnisch 6 from the interior 2 through a housing bottom wall 7 of the housing 3 leads to the outside.
- the guided through the Abtauwassertechnisch 6 condensation water is passed into a condensation water container 8 according to the invention.
- the condensation water container 8 is in this embodiment in a base region 9 below the housing 3, but may be arranged at any other suitable location outside the interior 2 depending on the design of the refrigerator 1.
- the condensation water container 8 is constructed of good heat-conducting aluminum and has a bottom wall 10 and side walls 11, which have a wall thickness of 3 mm.
- aluminum instead of aluminum, other highly thermally conductive metals or alloys, such as Al-Mg alloys are conceivable as a good heat conducting material for the condensation water tank.
- thermally conductive plastics such as carbon fiber reinforced plastics, or graphite are preferred materials for the condensation water 8.
- the refrigerator 1 has condenser tubes 12, which are arranged in this embodiment in a machine room 13 below the interior 2. However, they can also conventionally be arranged running on a rear side of the refrigeration device 1.
- a pipe section 14 as a section of the condenser tubes 12 extends through walls of the condensation water tank 8. As indicated schematically, the pipe section 14 is at least partially guided in the side walls 11 and the bottom wall 10 of the condensation water 8. The pipe section 14 does not pass through the condensation water, but is guided by the remaining condenser tubes 12 in a side wall 11 and led out after feldanderartigem course through the bottom wall 10 of another side wall 11 and passes back to the remaining condenser 12th
- the condenser tubes 12 are arranged to save space in the machine room 13 and therefore have only a small overall length. Therefore, a forced ventilation 15 is disposed in the immediate vicinity of the condenser 12, which leads to an increased air movement and thus to a discharge of air heated by the condenser tubes 12 with their warm refrigerant.
- the air is sucked through a cooling air channel in the base region 9 of an area in front of the refrigeration device 1 through ventilation slots 16 and led out through an exhaust duct 17 from the base area.
- the led out heated exhaust air is illustrated by arrows 18.
- Cooling air duct and exhaust duct 17 are parallel to each other, so that in the Fig. 1 only the exhaust duct 17 is shown. Since a fan is already provided in this embodiment, its use for increased evaporation of condensate in the condensation water does not lead to increased energy consumption. On the contrary, a stronger evaporative cooling is achieved by the increased evaporation of the condensation water, whereby the refrigerant is cooled more strongly in the condenser tubes 12 and thus a lower energy consumption is achieved.
Abstract
Description
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere Haushaltskältegerät, nach dem Oberbegriff von Anspruch 1.The present invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, according to the preamble of
Ein solches Kältegerät ist aus der Gebrauchsmusterschrift
Mit dieser Anordnung soll erreicht werden, dass bei modernen Kältegeräten mit hochwertiger Isolation trotz der geringen Abwärme des Verdichters das Tauwasser mit einer Rate verdunstet, mit der es aus dem Innenraum des Kältegeräts nachfließt. Damit soll verhindert werden, dass eine zusätzliche Heizung am Auffangbehälter zum Verdunsten benötigt wird, was den Energiebedarfs des Geräts erhöhen würde.With this arrangement is to be achieved that in modern refrigeration appliances with high-quality insulation despite the low heat loss of the compressor, the condensate evaporates at a rate with which it flows from the interior of the refrigerator. This is to prevent that an additional heater is required for evaporation on the collecting container, which would increase the energy consumption of the device.
Bei diesem bekannten Kältegerät besteht jedoch der Nachteil, dass die Verdunstungsrate immer noch zu niedrig ist.In this known refrigeration device, however, has the disadvantage that the evaporation rate is still too low.
Aufgabe der Erfindung ist daher, ein Kältegerät mit Tauwasserbehälter zu schaffen, bei dem die Verdampfung des Tauwassers noch effizienter gewährleistet ist.The object of the invention is therefore to provide a refrigeration device with condensation water tank, in which the evaporation of the condensation water is ensured even more efficient.
Die Aufgabe wird mit einem Kältegerät mit den Merkmalen des Anspruchs 1 gelöst. Die Erfindung basiert auf der Einsicht, dass die Verdunstungskälte des Abtauwassers im Tauwasserbehälter die Verflüssigertemperatur absenkt. Die Erfindung hat den überraschenden Effekt, dass dadurch nicht nur keine zusätzliche Energie zugeführt werden muss, um Tauwasser zu verdampfen, sondern sogar der Energieverbrauch des Kältegeräts reduziert wird.The object is achieved with a refrigerator with the features of
Zusätzlich reduziert der Auffangbehälter, d.h. Tauwasserbehälter, überraschend auch dann den Energieverbrauch, wenn der Tauwasserbehälter leer ist, weil beispielsweise das Tauwasser bzw. Kondenswasser bereits ganz verdampft wurde. Dies ist dadurch gewährleistet, dass die gute Wärmeleitfähigkeit des Auffangbehälters dazu führt, dass vom trockenen Auffangbehälter Wärme abgestrahlt wird. Unter einer guten Wärmeleitfähigkeit des Auffangbehälters wird im Rahmen dieser Erfindung eine Wärmeleitfähigkeit von 1 bis 200 W/mK, insbesondere von 10 bis 100 W/mK verstanden.In addition, the collecting container, ie condensation water tank, surprisingly also reduces the energy consumption when the condensation water tank is empty, because, for example, the condensation or condensed water has already completely evaporated. This is ensured by the fact that the good thermal conductivity of the collecting container causes heat to be radiated from the dry collecting container. In the context of this invention, a good thermal conductivity of the collecting container is understood as meaning a thermal conductivity of from 1 to 200 W / mK, in particular from 10 to 100 W / mK .
Die Führung des Rohrabschnitts der Verflüssigerrohrs innerhalb mindestens einer Wandung des Tauwasserbehälters schützt den Rohrabschnitt vor Korrosion.The guidance of the pipe section of the condenser tube within at least one wall of the condensation water container protects the pipe section from corrosion.
Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der Unteransprüche.Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
Zweckmäßigerweise ist das wärmeleitende Material des Tauwasserbehälters, der auch als Verdunstungsbehälter bezeichnet werden kann, aus der Gruppe bestehend aus Aluminium, Al-Mg-Legierung, Graphit und hoch wärmeleitenden Kunststoffen ausgewählt. Selbstverständlich sind aber auch alle anderen Materialen hoher Wärmeleitung für die Ausbildung der Wandungen des Tauwasserbehälters geeignet, die auch hinsichtlich Korrosion und Wärmeausdehnungskoeffizient eine lange Lebensdauer des Tauwasserbehälters gewährleisten.Conveniently, the heat-conducting material of the condensation water tank, which can also be referred to as an evaporation tank, selected from the group consisting of aluminum, Al-Mg alloy, graphite and highly thermally conductive plastics. Of course, however, all other materials high heat conduction suitable for the formation of the walls of the condensation water, which also ensure a long life of the condensation water with regard to corrosion and thermal expansion coefficient.
Bei Einsatz von hoch wärmeleitendem Kunststoff ist dieser vorzugsweise aus der Gruppe der mit Füllstoffen, wie z.B. Graphitpulver, Metallpulver, insbesondere hier Aluminium und Kupfer oder ausgerichteten Kohlefasern versehenen Kunststoffen, wie z.B. Polypropylen, Polystyrol oder Polyäthylen. Derart hochwärmeleitende Kunststoffe sind z.B. unter dem Handelsnamen CooIPoly der Fa. Intratron oder unter dem Handelsnamen "Omegabond (www.omega.de) bekannt. Bei kohlefaserverstärktem Kunststoff übernehmen hauptsächlich die in Kunststoff eingebetteten Kohlefasern die Wärmeleitung.When using highly heat-conductive plastic, this is preferably from the group of plastics provided with fillers, such as graphite powder, metal powder, in particular aluminum and copper or oriented carbon fibers, such as polypropylene, polystyrene or polyethylene. Such highly heat-conducting plastics are known, for example, under the trade name CooIPoly from Intratron or under the trade name "Omegabond ( www.omega.de )." In the case of carbon-fiber reinforced plastic, the carbon fibers embedded in plastic take over the heat conduction.
Vorteilhafterweise ist der Rohrabschnitt durch zumindest eine Seitenwandung und/oder eine Bodenwandung des Verdunstungsbehälters geführt. Dies erhöht noch die Effizienz, mit der die Verdunstungskälte des Tauwassers ein Kältemittel im Verflüssigerrohr abkühlt. Durch die Anordnung des Rohrabschnitts in der Bodenwandung wird selbst dann, wenn nur noch sehr wenig Tauwasser im Tauwasserbehälter vorhanden ist, eine hohe Wärmeübertragungsrate vom Rohrabschnitt zum Tauwasser gewährleistet, da sich das Tauwasser unmittelbar über der Bodenwandung befindet. Durch eine Kombination mit einer Führung des Rohrabschnitts in Seitenwandungen des Tauwasserbehälters ist die Wärmeübertragung noch zusätzlich erhöht.Advantageously, the pipe section is guided through at least one side wall and / or a bottom wall of the evaporation tank. This further increases the efficiency with which the evaporative cooling of the condensation water cools a refrigerant in the condenser tube. The arrangement of the pipe section in the bottom wall, even if only very little condensation water is present in the condensate tank, ensures a high heat transfer rate from the pipe section to the condensation, since the condensation is located directly above the bottom wall. By a combination with a guide of the pipe section in side walls of the condensation water heat transfer is further increased.
Bevorzugt ist der Rohrabschnitt in der zumindest einen Wandung mäanderartig geführt. Dies erhöht die Gesamtstrecke, die der Rohrabschnitt in dem Tauwasserbehälter zurücklegt und somit auch die Wärmeübertragung. Die Reduzierung des Energieverbrauchs ist so besonders hoch.Preferably, the pipe section is guided in a meandering manner in the at least one wall. This increases the total distance that covers the pipe section in the condensation water tank and thus the heat transfer. The reduction of energy consumption is so high.
Vorzugsweise ist die Wandungsdicke des Behälters zumindest stellenweise größer als 0,3 mm, insbesondere größer als 0,5 mm, bevorzugt zwischen 0,3 und 5 mm, besonders bevorzugt zwischen 2 und 3 mm. Diese große Dicke bewirkt eine hohe Wärmekapazität der Wandungen, wodurch dem Kältemittel besonders viel Wärme entzogen werden kann. Dies ist insbesondere auch dann der Fall, wenn der Tauwasserbehälter nach dem Verdampfen des Tauwassers trocken ist.Preferably, the wall thickness of the container is at least in places larger than 0.3 mm, in particular greater than 0.5 mm, preferably between 0.3 and 5 mm, particularly preferably between 2 and 3 mm. This large thickness causes a high heat capacity of the walls, whereby the refrigerant can be withdrawn a lot of heat. This is especially the case when the condensation water tank is dry after evaporation of the condensation water.
Zweckmäßigerweise ist der Rohrabschnitt in den Wandungen eingegossen, umspritzt, eingepresst oder eingeklebt. Somit wird eine besonders innige Verbindung des Rohrabschnitts mit den Wandungen erzielt. Dies hat eine besonders gute Wärmeübertragung zur Folge.Conveniently, the pipe section is poured into the walls, sprayed, pressed or glued. Thus, a particularly intimate connection of the pipe section is achieved with the walls. This results in a particularly good heat transfer.
Vorteilhafterweise ist in der Nähe des Tauwasserbehälters eine Zwangsbelüftung, wie beispielsweise durch einen Ventilator, vorgesehen, die bewirkt, dass ein Luftstrom über den Tauwasserbehälter bewegt wird. Dies steigert die Verdunstungsrate des Tauwassers und erhöht somit die Verdunstungskälte durch das verdunstende Tauwasser. Auch bei trockenem Tauwasserbehälter wird durch Entfernen von warmer Luft in unmittelbarer Umgebung des Tauwasserbehälters ein besonders effizientes Abkühlen des Kältemittels im Verflüssigerrohr erzielt. Dies ist insbesondere aufgrund der Kombination mit der guten Wärmeleitfähigkeit des Materials der Wandungen der Fall. Der Einsatz einer Zwangsbelüftung ist insbesondere dann vorteilhaft, wenn das Kältegerät ohnehin über einen Außenventilator verfügt, so dass zum Betreiben der Zwangsbelüftung kein zusätzlicher Energieverbrauch anfällt.Advantageously, a forced ventilation, such as by a fan, is provided in the vicinity of the condensation water container, which causes an air flow to be moved via the condensation water container. This increases the evaporation rate of the dew water and thus increases the evaporation cold through the evaporating condensate. Even with a dry condensation water tank, a particularly efficient cooling of the refrigerant in the condenser tube is achieved by removing warm air in the immediate vicinity of the condensation water tank. This is especially because of the combination with the good Thermal conductivity of the material of the walls of the case. The use of forced ventilation is particularly advantageous when the refrigerator already has an outdoor fan, so that no additional energy consumption is incurred to operate the forced ventilation.
Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung und der beigefügten Zeichnung, in der eine bevorzugte Ausführungsform der Erfindung veranschaulicht ist.Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which a preferred embodiment of the invention is illustrated.
Das erfindungsgemäße Kältegerät 1 gemäß einem in
Das Kältegerät 1 besitzt Verflüssigerrohre 12, die in diesem Ausführungsbeispiel in einem Maschinenraum 13 unterhalb des Innenraums 2 angeordnet sind. Sie können jedoch auch herkömmlich an einer Rückseite des Kältegeräts 1 verlaufend angeordnet sein. Ein Rohrabschnitt 14 als Teilabschnitt der Verflüssigerrohre 12 verläuft durch Wandungen des Tauwasserbehälter 8. Wie schematisch angedeutet, ist der Rohrabschnitt 14 zumindest teilweise in den Seitenwandungen 11 und der Bodenwandung 10 des Tauwasserbehälters 8 geführt. Der Rohrabschnitt 14 verläuft nicht durch das Tauwasser, sondern ist von den restlichen Verflüssigerrohren 12 kommend in eine Seitenwandung 11 geführt und nach mäanderartigem Verlaufen durch die Bodenwandung 10 aus einer weiteren Seitenwandung 11 herausgeführt und gelangt wieder zu den restlichen Verflüssigerrohren 12.The
In diesem Ausführungsbeispiel sind die Verflüssigerrohre 12 platzsparend im Maschinenraum 13 angeordnet und besitzen daher nur eine geringe Gesamtlänge. Daher ist eine Zwangsbelüftung 15 in unmittelbarerer Nähe der Verflüssigerrohe 12 angeordnet, die für eine verstärkte Luftbewegung und somit zu einem Abführen von durch die Verflüssigerrohre 12 mit ihrem warmen Kältemittel erwärmter Luft führt. Die Luft wird durch einen Kühlluftkanal im Sockelbereich 9 von einem Bereich vor dem Kältegerät 1 durch Lüftungsschlitze 16 angesaugt und durch einen Abluftkanal 17 aus dem Sockelbereich herausgeführt. Die herausgeführte erwärmte Abluft ist mit Pfeilen 18 verdeutlicht.In this embodiment, the
