Abstract
Description
Die vorliegende Erfindung betrifft eine Klimatisierungsvorrichtung zum Heizen und/oder Kühlen des Innenraums eines Fahrzeugs, insbesondere eines Kraftfahrzeugs, mit einem thermoelektrischen Element, das eine erste Fläche zum Klimatisieren des Innenraums und eine zweite Fläche aufweist, wobei beim Anlegen einer elektrischen Spannung an das thermoelektrische Element eine Temperaturdifferenz zwischen den beiden Flächen auftritt.The The present invention relates to an air conditioning apparatus for Heating and / or cooling of the Interior of a vehicle, in particular a motor vehicle, with a thermoelectric element having a first surface for Air conditioning the interior and having a second surface, wherein when mooring an electrical voltage to the thermoelectric element a Temperature difference between the two surfaces occurs.
Es ist bekannt, den Fahrzeuginnenraum durch die Zufuhr von Luft zu heizen oder zu kühlen, welche wärmer bzw. kälter als die im Innenraum befindliche Luft ist. Zum Erwärmen des Innenraums wird die zugeführte Luft üblicherweise durch die Abwärme des Motors erwärmt und dann dem Fahrzeuginnenraum zugeführt. Soll dem Innenraum kühlere Luft zugeführt werden, werden üblicherweise Kompressionskälteanlagen verwendet, welche die dem Innenraum zugeführte Luft abkühlen.It is known to the vehicle interior by the supply of air to heat or cool which ones cozy or colder as the air in the interior is. For heating the Interior is the fed Air usually through the waste heat heated the engine and then supplied to the vehicle interior. Should the interior cooler air supplied become, become usually Compression refrigeration systems used, which cool the air supplied to the interior.

Es ist die Aufgabe der vorliegenden Erfindung, eine Klimatisierungsvorrichtung zum Heizen und/oder Kühlen des Innenraums eines Fahrzeugs der eingangs genannten Art so weiterzubilden, dass der Fahrzeuginnenraum mit einem möglichst hohen Wirkungsgrad klimatisiert wird.It The object of the present invention is an air conditioning device for heating and / or cooling the interior of a vehicle of the type mentioned so educate, that the vehicle interior with the highest possible efficiency is air conditioned.
Diese Aufgabe wird erfindungsgemäß durch eine Klimatisierungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den Unteransprüchen.These The object is achieved by a Air conditioning device with the features of claim 1 solved. advantageous Training and further developments emerge from the subclaims.
Die erfindungsgemäße Klimatisierungsvorrichtung ist dadurch gekennzeichnet, dass die zweite Fläche thermisch mit der Luft gekoppelt ist, die durch einen Abluftkanal aus dem Innenraum abgeführt wird. Auf diese Weise kann ein sehr hoher Systemwirkungsgrad realisiert werden. Soll nämlich der Fahrzeuginnenraum gekühlt werden, so dass die erste Fläche des thermoelektrischen Elements die kalte Fläche darstellt und die zweite Fläche die heiße Fläche, wird die heiße Fläche mit der schon abgekühlten Innenraumabluft gekühlt. Diese Anordnung hat somit einen besseren Wirkungsgrad als bei einer Anordnung, bei der die heiße Fläche thermisch mit dem warmen Motorraum oder der wärmeren Außenluft gekoppelt ist. Soll andererseits der Fahrzeuginnenraum erwärmt werden, so dass die erste Fläche des thermoelektrischen Elements die heiße Fläche ist und die zweite Fläche die kalte Fläche ist, wird die kalte Fläche, statt üblicherweise mit der kalten Außenluft, mit der bereits erwärmten Innenraumabluft thermisch gekoppelt, so dass der Systemwirkungsgrad erhöht wird.The Air conditioning device according to the invention is characterized in that the second surface thermally with the air is coupled, which is discharged through an exhaust duct from the interior. In this way, a very high system efficiency can be realized become. Namely the vehicle interior cooled be so that the first surface of the thermoelectric element represents the cold surface and the second area the hot one Area, will be the hot one area with the already cooled interior exhaust air cooled. This arrangement thus has a better efficiency than in a Arrangement in which the hot area thermally coupled with the warm engine compartment or the warmer outside air. Should On the other hand, the vehicle interior will be heated, so that the first area of the thermoelectric element is the hot surface and the second surface is the cold area is, the cold surface, instead of usual with the cold outside air, with the already warmed up Indoor exhaust air is thermally coupled, so the system efficiency elevated becomes.
Bei dem thermoelektrischen Element handelt es sich insbesondere um ein Peltierelement. Die beiden Flächen des thermoelektrischen Elements sind jeweils mit einem Wärmetauscher thermisch gekoppelt.at the thermoelectric element is in particular a Peltier element. The two surfaces of the thermoelectric element are each provided with a heat exchanger thermally coupled.
Gemäß einer bevorzugten Ausgestaltung der erfindungsgemäßen Klimatisierungsvorrichtung weist diese einen ersten Flüssigkeitskreislauf auf, der einerseits über einen ersten Wärmetauscher mit der zweiten Fläche thermisch gekoppelt ist und andererseits über einen zweiten Wärmetauscher thermisch mit der Luft gekoppelt ist, die durch einen Abluftkanal aus dem Innenraum abgeführt wird.According to a preferred embodiment of the air conditioning device according to the invention, this has a first fluid circuit, which is thermally coupled on the one hand via a first heat exchanger with the second surface and others On the other hand is thermally coupled via a second heat exchanger with the air, which is discharged through an exhaust duct from the interior.
Gemäß einer Weiterbildung dieser Ausgestaltung ist die erste Fläche mit einem Luftwärmetauscher thermisch gekoppelt. Der Luftwärmetauscher ist vorzugsweise im Innenraum des Fahrzeugs angeordnet.According to one Further development of this embodiment is the first surface with an air heat exchanger thermally coupled. The air heat exchanger is preferably arranged in the interior of the vehicle.
Gemäß einer anderen bevorzugten Ausgestaltung weist die Klimatisierungsvorrichtung einen zweiten Flüssigkeitskreislauf auf der einerseits über einen dritten Wärmetauscher mit der ersten Fläche thermisch gekoppelt ist und andererseits über einen vierten Wärmetauscher thermisch mit dem Innenraum gekoppelt ist. Diese Ausgestaltung hat den Vorteil, dass das thermoelektrische Element sehr variabel platziert werden kann. Es muss insbesondere nicht in unmittelbarer Nähe des Fahrzeuginnenraums angeordnet sein, da die thermische Kopplung des thermoelektrischen Elements mit dem Fahrzeuginnenraum über den zweiten Flüssigkeitskreislauf erfolgt.According to one Another preferred embodiment, the air conditioning device a second fluid circuit on the one hand about one third heat exchanger thermally with the first surface is coupled and on the other hand over a fourth heat exchanger thermally coupled to the interior. This embodiment has the advantage that the thermoelectric element placed very variable can be. In particular, it does not have to be arranged in the immediate vicinity of the vehicle interior be because the thermal coupling of the thermoelectric element with the vehicle interior over the second fluid circuit he follows.
Gemäß einer Weiterbildung der erfindungsgemäßen Klimatisierungsvorrichtung ist der erste Flüssigkeitskreislauf mit einem Motorkühlkreislauf thermisch gekoppelt. Diese zusätzliche Kopplung an den Motorkühlkreislauf kann über Ventile erfolgen, so dass dem System eine alternative Wärmequelle bzw. -senke zur Verfügung steht, die insbesondere wahlweise zugeschaltet werden kann.According to one Further development of the air conditioning device according to the invention is the first fluid circuit thermally with an engine cooling circuit coupled. This additional Coupling to the engine cooling circuit can over Valves are made, giving the system an alternative heat source or sink available is, in particular, can be optionally switched.
Die Erfindung wird nun anhand von Ausführungsbeispielen mit Bezug zu den Zeichnungen erläutert.The The invention will now be described with reference to exemplary embodiments explained to the drawings.
