Die Erfindung betrifft eine Klimaanlage mit Kältespeicher für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruches 1.The The invention relates to an air conditioner with cold storage for a motor vehicle according to the generic term of claim 1.
Es ist ein Ziel der Kraftfahrzeughersteller, den Kraftstoffverbrauch des Fahrzeugs zu reduzieren. Eine Maßnahme zur Reduzierung des Kraftstoffverbrauchs ist das Abschalten des Motors bei vorübergehendem Stillstand, beispielsweise beim Halten an einer Ampel. Dieses vorübergehende Abschalten des Motors wird auch Idle-stop-Betrieb genannt. Diese Maßnahme wird bei heutigen verbrauchsarmen Fahrzeugen, wie beispielsweise bei dem sogenannten Dreiliter-Fahrzeug, bereits eingesetzt. Bei Fahrzeugen, die über den Idle-stop-Betriebsmodus verfügen, ist im innerstädtischen Verkehr ca. 25–30 % der Fahrzeit der Motor ausgeschaltet.It One of the automotive manufacturers' goals is fuel economy to reduce the vehicle. A measure to reduce the Fuel consumption is the shutdown of the engine at temporary Standstill, for example when stopping at a traffic light. This temporary Shutting down the engine is also called idle-stop operation. These measure is used in today's low-consumption vehicles, such as in the so-called three-liter vehicle, already used. at Vehicles over have the idle-stop mode of operation, is in the inner city Traffic about 25-30 % of travel time the engine is off.
Dies ist ein Grund, warum derartige Fahrzeuge nicht mit einer Klimaanlage ausgerüstet sind, denn bei Motorstillstand kann auch ein für eine Klimaanlage notwendiger Kompressor nicht angetrieben werden, so dass im Idle-stop-Betrieb eine Klimaanlage die notwendige Kälteleistung nicht bereitstellen kann.This is one reason why such vehicles are not equipped with air conditioning equipped are, because at engine standstill can also be necessary for an air conditioner Compressor can not be driven, so in idle-stop operation, air conditioning the necessary cooling capacity can not provide.

Diese Aufgabe wird gelöst durch eine Klimaanlage mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.outgoing From this prior art, it is an object of the invention, a improved air conditioning available to deliver. This task is solved by an air conditioner The features of claim 1. Advantageous embodiments are the subject the dependent claims.
Erfindungsgemäß ist eine Klimaanlage mit Kältespeicher für ein Kraftfahrzeug vorgesehen mit einem Kältemittelkreislauf, der einen Verdampfer, welcher zum Abkühlen von zu konditionierender Luft für den Innenraum dient, wobei ein in einem Kältespeicher enthaltenes Kältespeichermedium vorgesehen ist, das im Bereich des Verdampfers angeordnet ist, mindestens ein Expansionsorgan und mindestens einen Sammler aufweist, wobei in mindestens einem Kältespeicherelement mindestens ein kältemittelführendes Rohr angeordnet ist. Die Anordnung des kältemittelführenden Rohres in einem Kältespeicherelement ergibt einen sehr guten Wärmeübergang, so dass das Kältespeichermedium schnell einen Phasenwechsel durchlaufen kann. Dabei kann das mit kältemittelführende Rohr in das mit dem Kältespeichermedium befüllte Kältespeicherelement eingesteckt sein oder aber direkt hierin ausgebildet sein, wobei das Kältespeichermedium bevorzugt das Kältemittel von allen Seiten umgibt, wobei insbesondere eine Rohr-in-Rohr-Anordnung vorgesehen ist.According to the invention is a Air conditioning with cold storage for a Motor vehicle provided with a refrigerant circuit, the one Evaporator, which for cooling of conditioned air for the interior is used, wherein a cold storage medium contained in a cold storage is provided, which is arranged in the region of the evaporator, at least an expansion organ and at least one collector, wherein in at least one cold storage element at least one refrigerant-carrying Tube is arranged. The arrangement of the refrigerant-carrying pipe in a cold storage element gives a very good heat transfer, so that the cold storage medium can quickly go through a phase change.

Das kältemittelführende und das Kältespeichermedium enthaltende Rohr ist bevorzugt als ein doppelwandiges Flachrohr ausgebildet, wobei sich das Kältemittel im zentralen Bereich und das Kältespeichermedium im äußeren Bereich befindet. Gemäß einer weiteren bevorzugten Ausführungsform weist das doppelwandige Flachrohr Stege auf, die das außen liegende mit dem innen liegenden Flachrohr verbinden. Dadurch, dass der Kältespeicher direkten Luftkontakt hat, ergibt sich eine sehr gute Dynamik beim Wärmeübergang, so dass im Bedarfsfall, d.h. im Idle-stop-Betrieb, die volle Kälteleistung sofort zur Verfügung steht.The refrigerant-carrying and the cold storage medium containing pipe is preferred as a double-walled flat tube formed, wherein the refrigerant in the central area and the cold storage medium in the outer area located. According to one further preferred embodiment the double-walled flat tube webs on which the outside connect with the inner flat tube. Because of the cold storage has direct air contact, results in a very good momentum Heat transfer, so that if necessary, i. in idle-stop mode, the full cooling capacity immediately available stands.
Das kältemittelführende Rohr beziehungsweise die kältemittelführenden Kanäle des Rohres endeten bevorzugt in einem Sammler. Bevorzugt sind zwei Sammler vorgesehen, wobei die Sammler und die kältemittelführenden Rohre einen verdampferartigen Aufbau aufweisen, so dass sie eine Art zweiten Verdampfer bilden, und der Zwischenraum der kältemittelführenden Rohre von dem Fahrzeuginnenraum zuzuführender Luft durchströmbar ist. Ebenfalls enden die kältespeichermediumführenden Rohre beziehungsweise Kanäle bevorzugt in einem getrennt hiervon ausgebildeten Kältespeichermedium-Sammelbehälter. Dies ermöglicht eine gemeinsame Befüllung mit dem Kältespeichermedium, so dass eine einfache und schnelle Befüllung der kältespeichermediumführenden Rohre beziehungsweise Kanäle möglich ist. Die Ausgestaltung kann derart sein, dass erster und zweiter Verdampfer ein stückig ausgebildet sind, d.h. der zweite Verdampfer mit dem Kältespeicher ist in den ersten Verdampfer integriert.The refrigerant-carrying pipe or the refrigerant-carrying channels of the tube preferably ended in a collector. Preferred are two Collector provided, with the collector and the refrigerant-carrying pipes an evaporator-like Structure so that they form a kind of second evaporator, and the space of the refrigerant-carrying Tubes can be flowed through by the vehicle interior air to be supplied. Also The cold storage medium carrying pipes end or channels preferably in a cold storage medium collecting container formed separately therefrom. This allows a common filling with the cold storage medium, so that easy and fast filling of the cold storage medium leading Pipes or channels possible is. The embodiment may be such that first and second Evaporator one piece are formed, i. the second evaporator with the cold storage is integrated in the first evaporator.
Bevorzugt fluchten Flachrohrreihen des Verdampfers und die Rohre, in welchen die Kältespeicherelemente integriert sind, miteinander, so dass der Luftströmungswiderstand möglichst gering ist, jedoch können die Flachrohrreihen auch versetzt angeordnet sein, oder die Rohre, in welchen die Kältespeicherelemente integriert sind, können gegenüber den Flachrohren des Verdampfers verdreht angeordnet sein. Eine mehrflutige Ausgestaltung der Rohre, in welchen die Kältespeicherelemente integriert sind, d.h. mehrere Reihen mit kältespeichermediumführenden Rohren, ist ebenfalls möglich, wie deren Umlenkungen in der Breite und/oder Tiefe.Preferably aligned flat tube rows of the evaporator and the tubes in which the cold storage elements are integrated with each other, so that the air flow resistance is minimized, but the flat tube rows can also be offset be ordered, or the tubes in which the cold storage elements are integrated, can be arranged rotated relative to the flat tubes of the evaporator.

Der integrierte Kältespeicher ist bevorzugt in normaler Luftströmungsrichtung gesehen nach dem Verdampfer, insbesondere direkt in Anschluss an den Verdampfer, angeordnet, aber es ist ebenfalls eine Anordnung vor dem Verdampfer oder in den Verdampfer integriert, insbesondere bei einem zweireihigen Verdampfer zwischen den beiden Flachrohrreihen, oder beabstandet vom Verdampfer möglich. Insbesondere im Falle einer beabstandeten Anordnung vom Verdampfer kann die Größe des Sammlers mit Kältespeicher entsprechend dem vorhandenen Bauraum und/oder den Erfordernissen angepasst werden. Besonders vorteilhaft ist, dass der bestehende Verdampfer nicht abgeändert werden muss, so dass eine relativ einfache Integration des Kältespeichers in bestehende Systeme möglich ist.Of the integrated cold storage is preferably seen in the normal air flow direction the evaporator, in particular directly after the evaporator, arranged, but it is also an arrangement in front of the evaporator or integrated in the evaporator, especially in a double row Evaporator between the two rows of flat tubes, or spaced possible from the evaporator. In particular, in the case of a spaced arrangement of the evaporator can be the size of the collector with cold storage according to the available space and / or the requirements be adjusted. It is particularly advantageous that the existing evaporator not changed so that a relatively simple integration of the cold storage in existing systems possible is.
Der Kältespeicher besteht bevorzugt aus Aluminium, insbesondere innen und/oder außen beschichtetem Aluminium, gegebenenfalls auch Kupfer, einer Kupfer-Zink-Legierung, Kunstharz oder Kunststoff. Ein Aluminium-Behälter hat den Vorteil, dass er sich mit den übrigen Teilen des Verdampfers problemlos verlöten lässt. Dabei handelt es sich bevorzugt um ein stranggepresstes Flachrohr, das eine Mehrzahl von Kanälen aufweist, wobei ein Teil der Kanäle das Kältespeichermedium und der andere Teil der Kanäle das Kältemittel enthalten.Of the cold storage is preferably made of aluminum, in particular coated inside and / or outside Aluminum, optionally copper, a copper-zinc alloy, Synthetic resin or plastic. An aluminum container has the advantage that it deals with the remaining parts of the evaporator solder easily leaves. This is preferably an extruded flat tube, the a plurality of channels having part of the channels the cold storage medium and the other part of the channels the refrigerant contain.
Beim Speichermedium handelt es sich bevorzugt um ein PCM-Material (phase change material), das bevorzugt kongruent schmelzende Clathrade, wie Decanol, Tetra-Penta-Hexadecan, LiC-IO33H2O, wässrige Salzlösungen oder organische Hydrate enthält oder hieraus gebildet ist. Das Speichermedium wird insbesondere bevorzugt durch Trimethylethan mit Wasser und Harnstoff-Zusätzen gebildet. Im Speichermedium können auch Keimbildner vorgesehen sein, welche die Kristallbildung beschleunigen.The storage medium is preferably a PCM material (phase change material), which preferably contains congruent melting clathrades, such as decanol, tetra-penta-hexadecane, LiC-IO 3 3H 2 O, aqueous salt solutions or organic hydrates or is formed therefrom , The storage medium is particularly preferably formed by trimethylethane with water and urea additives. Nucleating agents which accelerate crystal formation can also be provided in the storage medium.
Die Phasenumwandlungstemperatur des Speichermediums liegt vorzugsweise in einem Bereich von 0°C bis 30°C, insbesondere von 2°C bis 15°C, insbesondere bevorzugt von 4°C bis 12°C.The Phase change temperature of the storage medium is preferably in a range of 0 ° C up to 30 ° C, in particular of 2 ° C up to 15 ° C, especially preferably from 4 ° C up to 12 ° C.
Im Inneren des Kältespeicherelements können Einlagen, wie Rippenbleche, vorzugsweise aus Aluminium, jedoch sind auch andere Metalle oder Kunststoffe geeignet, oder andere Turbulenzeinlagen, wie Vliese oder Gestricke, bspw. aus Kunststoff oder Metall, oder Schäume, bspw. Metallschäume oder Kunststoffschäume, vorgesehen sein. Die Einlagen dienen einer Be- oder Verhinderung einer Strömungsausbildung des Kältespeichermediums.in the Interior of the cold storage element can Inserts such as ribbed plates, preferably of aluminum, however, are other metals or plastics, or other turbulence inserts, such as nonwovens or knits, for example. Of plastic or metal, or mousses, For example. Metal foams or Plastic foams, be provided. The deposits serve to prevent or prevent a flow training the cold storage medium.
Bevorzugt sind im Kältemittel-Kreislauf zwei Expansionsorgane, insbesondere bevorzugt thermostatische Expansionsventile, vorgesehen. Hierbei ist eines der Expansionsorgane dem Verdampfer und das andere Expansionsorgan dem Kältemittelstrom zugeordnet, welcher mit dem Kältespeicher in Verbindung steht, so dass im Normalebetrieb fast der gesamte Kältemittelmassenstrom dem Verdampfer zur Verfügung steht und der Kältemittelmassenstrom entlang dem Kältespeicher minimal ist. Im Idle-stop-Betrieb ist jedoch eine ausreichende Kältemittelversorgung des Kältespeichers gewährleistet.Prefers are in the refrigerant circuit two expansion organs, in particular preferably thermostatic expansion valves, intended. Here is one of the expansion organs the evaporator and the other expansion element associated with the refrigerant flow, which with the cold storage is connected, so that in normal operation almost the entire Refrigerant mass flow available to the evaporator stands and the refrigerant mass flow along the cold storage is minimal. In idle-stop operation, however, is a sufficient refrigerant supply the cold storage guaranteed.
Andere Regelungen sind ebenfalls möglich, insbesondere kann auch eine durchgehende Ausgestaltung des Verdampfers mit integriertem Kältespeicher vorgesehen sein, so dass nur ein Kältemitteleintritt und -austritt und somit ein Expansionsorgan vorgesehen ist. Hierbei ist der Kältemittelaustritt bevorzugt am Sammler des Verdampferbereichs, in welchem der Kältespeicher angeordnet ist, vorgesehen.Other Regulations are also possible, in particular can also be a continuous configuration of the evaporator with integrated cold storage be provided so that only a refrigerant inlet and outlet and thus an expansion organ is provided. Here is the refrigerant outlet preferably at the collector of the evaporator region, in which the cold storage is arranged provided.
