Abstract
Description
Die Erfindung betrifft die Anordnung einer Klimaanlage mit einem CO2-Kältemittelkreislauf im Vorderwagen eines Fahrzeugs mit einem integrierten Akkumulator und einem inneren Wärmetauscher.The invention relates to the arrangement of an air conditioning system with a CO 2 -Kältemittelkreislauf in the front of a vehicle with an integrated accumulator and an inner heat exchanger.
Eine
mit CO2 (R744) betriebene Klimaanlage in
einem Fahrzeug weist in dem dieser zu Grunde liegenden Kältemittelkreislauf
einen regelbaren Kompressor und in Strömungsrichtung nacheinander
einen Gaskühler,
den ersten Strömungszweig
eines inneren Wärmetauschers
und ein den Kältemittelfluss regelndes
Expansionsorgan zur Entspannung des Kältemittels als Hochdruckabschnitt
sowie einen Verdampfer, einen Akkumulator und den zweiten Strömungszweig
des inneren Wärmetauschers,
der in die Saugseite des Kompressors eingebunden ist, als Niederdruckabschnitt
auf. Dabei sind die genannten Komponenten jeweils durch Kältemittelleitungen
miteinander verbunden. Der CO2-Kältemittelkreislauf wird
mittels einer elektronischen Steuereinheit geregelt, in die die
von einem Temperatursensor am Ausgang des Verdampfers gemessene
Temperatur der durch diesen geströmten Luft eingegeben wird,
wie es beispielsweise in der
Der
im Kältemittelkreislauf
in Strömungsrichtung
nach dem Verdampfer angeordnete Akkumulator (Flüssigkeits-Auffangbehälter) dient
der Abscheidung und Zwischenspeicherung von Resten flüssigen Kältemittels
sowie deren Abgabe in kleinen Mengen, um den Kompressor vor Flüssigkeitsschäden zu schützen. Zudem übernimmt
der Akkumulator gleichzeitig eine Reinigung und vermittels eines
Trocknereinsatzes mit einem Trocknergranulat die Kältemitteltrocknung.
Der Aufbau eines solchen Akkumulators ist beispielsweise in der
Es ist Aufgabe der Erfindung, die Anordnung einer Klimaanlage mit einem CO2-Kältemittelkreislauf im Vorderwagen eines Fahrzeugs nach dem Oberbegriff des Anspruchs 1 so vorzunehmen, dass diese auch in kompakten Kleinfahrzeugen und Fahrzeugen mit einem querliegenden Motor anordbar ist.It is an object of the invention to make the arrangement of an air conditioner with a CO 2 -Kältemittelkreislauf in the front of a vehicle according to the preamble of claim 1 so that it can be arranged in compact small vehicles and vehicles with a transverse engine.
Diese Aufgabe wird bei der Anordnung einer Klimaanlage nach Anspruch 1 durch dessen kennzeichnendes Merkmal gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These The object is in the arrangement of an air conditioner according to claim 1 solved by its characterizing feature. Advantageous embodiments are in the subclaims listed.
Die Erfindung besteht darin, den im CO2-Kältemittelkreislauf im Niederdruckabschnitt zwischen dem Verdampfer und dem inneren Wärmetauscher erforderlichen Akkumulator im Bereich der Stirnwand des jeweiligen Fahrzeugs verdampfernah anzuordnen, an der freier Bauraum vorhanden ist oder geschaffen werden kann. Damit können Fahrzeuge mit einer CO2-betriebenen Klimaanlage ausgerüstet werden, die bislang nicht mit einer solchen ausrüstbar waren. Zudem kann als innerer Wärmetauscher ein Koaxialwärmetauscher eingesetzt werden, der im Kreislaufabschnitt zwischen dem an der Stirnwand angeordneten Akkumulator und dem am Frontend angeordneten Gaskühler erstreckt ist, wodurch die sonst zwischen dem Gaskühler und dem Expansionsventil erforderliche separate Hochdruckleitung, die auch den erster Strömungszweig im inneren Wärmetauscher bildet, ersetzt. Damit verbunden sind montagetechnische Vorteile, die den Aufwand für die Klimaanlage reduzieren. Der Akkumulator kann jedoch auch mit dem inneren Wärmetauscher kombiniert und als Baueinheit in den Kältemittelkreislauf integriert sein.The invention consists in disposing the accumulator required in the CO 2 refrigerant circuit in the low-pressure section between the evaporator and the inner heat exchanger in the region of the end wall of the respective vehicle, at which free space is available or can be created. This vehicle can be equipped with a CO 2- powered air conditioning, which were previously not equipped with such a system. In addition, a coaxial heat exchanger can be used as the inner heat exchanger, which is arranged in the circuit section between the arranged on the end wall accumulator and the front end gas cooler, whereby the otherwise required between the gas cooler and the expansion valve separate high-pressure line, which also the first flow branch in the inner heat exchanger forms, replaced. Connected with this are mounting advantages that reduce the cost of the air conditioning. However, the accumulator can also be combined with the inner heat exchanger and integrated as a unit in the refrigerant circuit.
