Kältemittels
Anwendung, die das komprimierte gasförmige Kältemittel einem Kältemittelverflüssiger zuführen. Bei
diesen Kompressoren wird die Drehbewegung einer in einem Kurbelgehäuse angeordneten
Taumelscheibe über
Verbindungselemente oder Kupplungsglieder in eine hin- und hergehende
Bewegung von in Zylindern bewegbar angeordneten Kolben umgesetzt.
In den Zylindern wird das aus einer Ansaugkammer angesaugte gasförmige Kältemittel
komprimiert und durch eine Ausstoßkammer ausgefördert. Dabei

Es ist Aufgabe der Erfindung, einen alternativen Kompressor für eine Fahrzeugklimaanlage nach dem Oberbegriff des Anspruchs 1 zu schaffen, der in seinem Aufbau einfach, platzsparend und geräuschreduziert ist.It The object of the invention is an alternative compressor for a vehicle air conditioning system to create according to the preamble of claim 1, in his Construction is simple, space-saving and noise-reduced.
Diese Aufgabe wird bei einem Kompressor nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.This Task is in a compressor according to the preamble of the claim 1 solved by its characteristic features. Advantageous configurations are in the subclaims listed.
Die Erfindung besteht darin, dass der Antrieb des Kompressors ein im Kompressorgehäuse angeordneter piezoelektrischer Stapelaktor ist, der sich bei einer anliegenden elektrischen Spannung in der Stapelrichtung ausdehnt und beim Ausschalten der Spannung wieder kontrahiert und der mit dem einen freien Ende am Kompressorgehäuse und mit dem anderen an einem Hubkolben abgestützt ist, der in einem Kompressionsraum mit wenigstens einem Ansaug- und einem Hochdruck-Auslassventil beweglich und dichtend angeordnet ist. Um eine ungehinderte oszillierende Bewegung des Stapelaktors sicherzustellen, ist zwischen diesem und dem Kompressorgehäuse ein Ringspalt ausgebildet. Mit diesem Kompressor ist ein Linearkompressor geschaffen, der keine rotierenden Teile und aufwendige Kupplungsteile aufweist und bei dem der Kältemittelmassenstrom zur Anpassung an eine momentan geforderte Kälteleistung über eine Steuerung der Versorgungsspannung und/oder der Ansteuerfrequenz und damit der Hubgröße und der Hubzahl des Stapelaktors je Zeiteinheit mit einem elektronischen Steuergerät, beispielsweise in Abhängigkeit vom Kältemitteldruck auf der Saugseite des Kompressors, elektronisch schnell und genau stufenlos geregelt wird. Ein derartiger Kompressor ist einfach aufgebaut, besteht aus nur wenigen Bauteilen und ist kleinbauend.The Invention is that the drive of the compressor compressor housing arranged piezoelectric stack actuator, which is at a applied electrical voltage extends in the stacking direction and contracted when the voltage was switched off and the one with one free end on the compressor housing and the other supported by a reciprocating piston is in a compression space with at least one intake and a high pressure exhaust valve is arranged movably and sealingly. To oscillate freely Ensuring movement of the stack actuator is between this and the compressor housing an annular gap is formed. With this compressor is a linear compressor created that has no rotating parts and expensive coupling parts and in which the refrigerant mass flow for Adaptation to a cooling capacity currently required via a Control of the supply voltage and / or the control frequency and thus the stroke size and the Number of strokes of the stack actuator per time unit with an electronic one Controller, for example depending from the refrigerant pressure on the suction side of the compressor, electronically fast and accurate is regulated continuously. Such a compressor is simply constructed, consists of only a few components and is small in size.
Durch eine sog. Doppelhubbauweise, bei der beidseits des Hubkolbens ein Kompressionsraum mit jeweils wenigstens einem Ansaug- und einem Hochdruck-Auslassventil ausgebildet ist, kann eine Leistungssteigerung (-verdoppelung) erreicht oder der Stapelaktor kann mit verminderter Ansteuerfrequenz betrieben werden, indem ein Arbeitshub bei gleicher Hubzahl je Zeiteinheit eingespart wird, ohne dass der Massenstrom verringert wird. Dieser wird sowohl beim Hin- als auch beim Herbewegen des Hubkolbens gefördert. Die damit verbundene Erhöhung der Pulsfrequenz ist insofern von Vorteil, dass Druckspitzen vermieden werden und die Druckunterschiede in den Kältemittelleitungen geringer sind.By a so-called double-stroke design, with one on both sides of the piston Compression room with at least one intake and one High pressure outlet valve trained, an increase in performance (doubling) can be achieved or the stack actuator can be operated with a reduced control frequency by one working stroke with the same number of strokes per unit of time is saved without reducing the mass flow. This is promoted both when the reciprocating piston is moved back and forth. The associated increase the pulse frequency is advantageous in that pressure peaks are avoided and the pressure differences in the refrigerant lines are smaller are.
Der Stapelaktor kann in einem im Kompressorgehäuse ausgebildeten Antriebsraum untergebracht sein, der durch eine Zwischenwand vom Kompressionsraum getrennt ist, wobei der Stapelaktor in Stapel- bzw. in axialer Richtung zwischen zwei Abschlusselementen, beispielsweise Platten, angeordnet ist, von denen das eine über ein Bewegungsübertragungsglied fest mit dem Hubkolben verbunden und über Federmittel an der Zwischenwand abgestützt ist und das andere an der Stirnwandung des Kompressorgehäuses anliegt. Dabei ist das Bewegungsübertragungsglied vorzugsweise ein als Kolbenstange dienender Stempel, der in der Zwischenwand bewegbar geführt und gegenüber dieser mit einem Dichtmittel abgedichtet ist.The stack actuator can be accommodated in a drive chamber formed in the compressor housing, which is separated from the compression chamber by an intermediate wall, the stack actuator being arranged in the stack or in the axial direction between two end elements, for example plates, one of which has a movement support member is fixedly connected to the reciprocating piston and is supported on the intermediate wall by spring means and the other abuts the end wall of the compressor housing. The movement transmission member is preferably a plunger serving as a piston rod, which is movably guided in the intermediate wall and is sealed off from it with a sealant.
Zur Abführung von im Stapelaktor entstehender Wärme kann das Kompressorgehäuse im Bereich des Antriebsraumes hohl ausgebildet sein, um den Durchfluss eines Kühlmediums zu ermöglichen. Vorteilhaft ist dieses das Kältemittel selbst. Dazu ist das Kompressorgehäuse mit wenigstens einer Eingangsöffnung und einer Ausgangsöffnung in die Saugleitung des Kompressors integriert und über das Ansaugventil und dem Kompressionsraum verbunden.to removal The compressor housing in the area can absorb heat generated in the stack actuator of the drive chamber to be hollow to the flow of a cooling medium to enable. Advantageous this is the refrigerant itself. For this purpose, the compressor housing with at least one inlet opening and an exit opening integrated in the suction line of the compressor and via the suction valve and the compression space connected.
Eine weitere vorteilhafte Ausführung wird darin gesehen, dass in einem Kompressor mehrere parallelgeschaltete Stapelaktoren in mehreren Antriebsräumen und diesen zugeordnete Kompressionsräume mit jeweils einem Hubkolben angeordnet sind. Mit einem derartigen Kompressor kann jegliche Anforderung an die Kälte- bzw. Wärmeleistung einer Klimaanlage erfüllt werden, so dass eine solche Ausführung insbesondere bei Fahrzeugen mit großem Kälte- bzw. Wärmebedarf verwendet werden kann. Hierbei ist es von besonderem Vorteil, wenn ein Kompressorgehäuse mit einem Stapelaktor, einem Kompressionsraum und einem diesem zugeordneten Hubkolben ein Modul bildet und mehrere Module baukastenartig zu einer Kompressoreinheit zusammengefügt bzw. -fügbar ausgebildet sind. Dabei sind die mit den Ansaug- und Hochdruck-Auslassventilen verbundenen Kältemittelleitungen jeweils außerhalb der Kompressoreinheit zusammengeführt.A further advantageous embodiment is seen in the fact that several compressors connected in parallel in one compressor Stack actuators in several drive rooms and assigned to them compression spaces are each arranged with a reciprocating piston. With such a Compressor can meet any cooling or heating performance requirements of an air conditioning system Fulfills be such an execution can be used especially in vehicles with high cooling or heating requirements can. It is particularly advantageous here if a compressor housing with a stack actuator, a compression chamber and a piston associated therewith forms one module and several modules in modular form to form a compressor unit together or -available are trained. The are connected to the intake and high pressure exhaust valves Refrigerant lines each outside the Compressor unit merged.
