Description
Die Erfindung betrifft ein Kältegerät.The invention relates to a refrigerator.
Kältegeräte entziehen einem Raum mit niedrigem Temperaturniveau, dem Innenraum des Kältegeräts, Wärme, um sie in einem Raum mit höheren Temperaturniveau, in der Regel in dem das Kältegerät umgebenen Raum, abzugeben. Hierzu werden so genannte Kältemittel verwendet, welche bei niedrigen Temperaturen verdampfen. Das Kältemittel zirkuliert in einem geschlossenen Rohrsystem, dem Kältemittelkreislauf. Bei dem bei Haushaltskältegeräten üblichen Kompressionssystem umfasst der Kältemittelkreislauf einen Verdampfer, einen Verdichter (Kompressor), einen Verflüssiger (Kondensator) und ein Drosselorgan. Im Verdampfer im Innenraum des Kältegeräts verdampft das Kältemittel bei niedrigem Druck und entzieht dem Innenraum dadurch Wärme. Das entstehende gasförmige Kältemittel wird aus dem Innenraum herausgeführt und über ein so genanntes Saugrohr dem Kompressor zugeführt, der es verdichtet und das verdichtete und dadurch in seiner Temperatur erhöhte Kältemittel an den Verflüssiger weiterleitet. Im Verflüssiger gibt das Kältemittel Wärme an die Umgebungsluft ab. Das dadurch verflüssigte Kältemittel gelangt dann durch das Drosselorgan, in dem der Druck abgebaut wird, in den Verdampfer. Der Kältemittelkreislauf beginnt von neuem.Refrigeration devices extract heat from a room with a low temperature level, the interior of the refrigeration device, in order to emit it in a room with a higher temperature level, as a rule in the room surrounding the refrigeration device. So-called refrigerants are used for this, which evaporate at low temperatures. The refrigerant circulates in a closed pipe system, the refrigerant circuit. In the compression system customary in household refrigeration appliances, the refrigerant circuit comprises an evaporator, a compressor (compressor), a condenser (condenser) and a throttle element. In the evaporator in the interior of the refrigerator, the refrigerant evaporates at low pressure, thereby extracting heat from the interior. The resulting gaseous refrigerant is led out of the interior and fed to the compressor via a so-called suction pipe, which compresses it and forwards the compressed and thus increased in temperature to the condenser. The refrigerant releases heat into the ambient air in the condenser. The refrigerant liquefied by this then passes through the throttle body, in which the pressure is reduced, into the evaporator. The refrigerant cycle starts again.
Als Drosselorgan wird bei Haushaltskältegeräten in der Regel ein Rohr mit geringem Durchmesser verwendet, insbesondere ein Kupferrohr. Das zum Kompressor führende Saugrohr dagegen besteht meist aus Aluminium, da es einstückig mit dem Verdampfer ausgebildet ist.A pipe with a small diameter, in particular a copper pipe, is generally used as a throttle device in household refrigeration appliances. The suction pipe leading to the compressor, on the other hand, usually consists of aluminum, since it is made in one piece with the evaporator.
Aus kälte- und energietechnischen Gründen ist ein Wärmetausch zwischen Saugrohr und Drosselrohr von Vorteil. Die beiden Rohre sollten also möglichst zumindest über einen Teil ihrer Länge in wärmeleitendem Kontakt miteinander stehen. Dies ist jedoch problematisch, da ein direkter Kontakt zwischen Aluminium und Kupfer aus Korrosionsgründen und auf Grund von Normvorgaben nicht zulässig ist.For cooling and energy-related reasons, heat exchange between the intake manifold and throttle tube is advantageous. The two pipes should therefore be in heat-conducting contact with one another at least over part of their length. However, this is problematic since direct contact between aluminum and copper is not permitted due to corrosion reasons and due to standard specifications.

Es ist daher eine Aufgabe der Erfindung, einen sicheren und fertigungsgerechten Kontaktschutz zwischen Drosselrohr und Saugrohr herzustellen.It is therefore an object of the invention to produce a safe and production-appropriate contact protection between the throttle tube and intake manifold.
Diese Aufgabe löst die Erfindung mit einem Kältegerät gemäß Anspruch 1.The invention achieves this object with a refrigeration device according to claim 1.
Erfindungsgemäß umfasst das Drosselrohr ein Metallrohr, welches zumindest über einen Teil seiner Länge mit einer Kunststoffschicht ummantelt ist. Der Vorteil einer derartigen Kunststoffschicht besteht zum einen darin, dass die Kunststoffschicht die beiden Rohre sehr gut elektrisch voneinander isoliert. Kunststoff ist zwar nicht sehr wärmeleitend, wird die Kunststoffschicht jedoch ausreichend dünn gewählt, findet dennoch ein Wärmetausch zwischen Saugrohr und Drosselrohr statt. Darüber hinaus ist die Kunststoffschicht besser korrosionsbeständig als beispielsweise eine galvanisch aufgetragene Zinkschicht. Schließlich ist es von Vorteil, dass die Kunststoffschicht leicht von den Rohrenden entfernt werden kann, zum Beispiel durch einfaches Aufschlitzen und Abziehen, wozu kein anders Werkzeug als der Fingernagel erforderlich ist. Aus verbindungstechnischen Gründen müssen die Rohrenden des Drosselrohrs blank sein, damit das Drosselrohr einerseits an der Einspritzstelle des Verdampfers und andererseits an einer Trockenpatrone bzw. am Ausgang des Verflüssigers montiert werden kann.According to the invention, the throttle tube comprises a metal tube which is coated with a plastic layer over at least part of its length. The advantage of such a plastic layer is, on the one hand, that the plastic layer very well electrically insulates the two tubes from one another. Plastic is not very thermally conductive, but if the plastic layer is chosen to be sufficiently thin, heat is still exchanged between the intake manifold and throttle tube. In addition, the plastic layer is more resistant to corrosion than, for example, a galvanically applied zinc layer. Finally, it is advantageous that the plastic layer can be easily removed from the pipe ends, for example by simply slitting and pulling off, for which purpose no tool other than the fingernail is required. For reasons of connection technology, the tube ends of the throttle tube must be bare so that the throttle tube can be mounted on the one hand at the injection point of the evaporator and on the other hand on a dry cartridge or at the outlet of the condenser.
Bevorzugt ist das Metallrohr des Drosselrohrs aus Kupfer oder einer Kupferlegierung, da Kupferrohre leicht herzustellen und ausreichend biegsam sind. Das Drosselrohr ist vorzugsweise ca. 30 cm bis 3 m lang und weist einen Außendurchmesser von ca. 0.5-4 mm und einen Innendurchmesser von ca. 0.5-0.8 mm auf. Durch Variieren der Länge oder des Innendurchmessers des Drosselrohrs kann der zu erreichende Druckverlust eingestellt werden.The metal tube of the throttle tube is preferably made of copper or a copper alloy, since copper tubes are easy to manufacture and are sufficiently flexible. The throttle tube is preferably approximately 30 cm to 3 m long and has an outer diameter of approximately 0.5-4 mm and an inner diameter of approximately 0.5-0.8 mm. The pressure loss to be achieved can be adjusted by varying the length or the inner diameter of the throttle tube.
Die Kunststoffschicht ist so dünn wie möglich herzustellen. Sie weist eine Dicke zwischen 20 und 500 µm, vorzugsweise zwischen 50 und 300 µm, besonders bevorzugt zwischen 100 und 200 µm auf. Dadurch wird gewährleistet, dass ausreichender Wärmeaustausch zwischen Drosselrohr und dem mit diesem in Kontakt stehenden Saugrohr stattfindet.The plastic layer should be made as thin as possible. It has a thickness between 20 and 500 μm, preferably between 50 and 300 μm, particularly preferably between 100 and 200 μm. This ensures that there is sufficient heat exchange between the throttle tube and the intake manifold in contact with it.
Die Kunststoffschicht weist einen thermoplastischen oder duroplastischen Kunststoff auf oder besteht vollkommen aus einem derartigen Kunststoff, wie beispielsweise PUR (Polyurethan), PP (Polypropylen) oder PE (polyäthylen) und/ oder die Kunststoffschicht ist mit einem wärmeleitfähigen Zusatzmaterial dotiert. Besonders bevorzugt ist der Kunststoff extrudierfähig, damit die Kunststoffschicht durch Co-Extrusion auf das Drosselrohr aufgetragen werden kann. Eine derartige co-extrudierte Beschichtung kann sich einfach und ohne Verletzung des Grundmaterials entfernen lassen.The plastic layer has a thermoplastic or thermosetting plastic or consists entirely of such a plastic, such as PUR (polyurethane), PP (polypropylene) or PE (polyethylene) and / or the plastic layer is doped with a thermally conductive additional material. The plastic is particularly preferably extrudable, so that the plastic layer can be applied to the throttle tube by co-extrusion. Such a co-extruded coating can be removed easily and without damaging the base material.
Beispielsweise kann der für die Kunststoffschicht verwendeten Kunststoffmasse Graphitpulver, weniger bevorzugt auch Metallpulver beigesetzt werden. Das wärmeleitfähige Zusatzmaterial kann auch Zinkoxid, Quarz, Stärke oder Talkum sein.For example, graphite powder, less preferably metal powder, can be added to the plastic mass used for the plastic layer. The thermally conductive additional material can also be zinc oxide, quartz, starch or talc.
Das Drosselrohr steht zumindest über einen Abschnitt seiner Länge in Berührungskontakt mit einem zu einem Kompressor führenden Saugrohr. Dabei berührt eine auf der Außenseite des Drosselrohrs angeordnete Kunststoffschicht die Außenseite des Saugrohrs zumindest an einem Punkt, sodass eine Wärmebrücke hergestellt wird. Besonders bevorzugt verläuft der mit dem Saugrohr in Kontakt stehende Abschnitt des Drosselrohrs parallel zu einem Abschnitt des Saugrohrs. Es ist auch möglich, dass das Drosselrohr mehrere Abschnitte aufweist, die parallel zu einem Abschnitt des Saugrohrs verlaufen, nämlich indem das Drosselrohr zumindest eine Haarnadelkurve durchläuft und somit mit zwei Abschnitten, die Kältemittel in gegenläufige Richtungen führen, an ein und demselben Abschnitt des Saugrohrs vorbeigeführt wird. Alternativ ist es auch möglich, das Drosselrohr oder einen Abschnitt des Drosselrohrs spiralförmig um das Saugrohr zu legen, sodass das Drosselrohr in diesem spiralförmigen Bereich über seine gesamte Länge in Berührungskontakt mit dem Saugrohr steht.The throttle pipe is in contact with at least a portion of its length with a suction pipe leading to a compressor. Here, a plastic layer arranged on the outside of the throttle tube touches the outside of the intake manifold at least at one point, so that a thermal bridge is produced. The section of the throttle pipe which is in contact with the intake pipe particularly preferably runs parallel to a section of the intake pipe. It is also possible for the throttle tube to have a plurality of sections which run parallel to a section of the intake manifold, namely by the throttle tube traversing at least one hairpin curve and thus bypassing one and the same section of the intake manifold with two sections which conduct refrigerants in opposite directions becomes. Alternatively, it is also possible to place the throttle tube or a section of the throttle tube spirally around the intake manifold, so that the throttle tube is in contact with the intake manifold in its spiral region over its entire length.
