Claims (6)

  1. Scrollverdichter (3, 103, 303, 403), der eine ortsfeste Spiralschnecke (23, 323, 423) und eine sich drehende Spiralschnecke (25, 125) umfasst, die jeweils ein Endpaneel (23a, 25a) aufweisen, das mit einem gewundenen Wandkörper (23b, 25b) ausgebildet ist, der sich von einer Seitenfläche davon aufrecht erstreckt, und mehrere Verdichtungskammern (C, C1, C2) zum Verdichten von Kältemittel bildet, indem sie miteinander in Eingriff gebracht werden,
    wobei mindestens eine der ortsfesten Spiralschnecke und der sich drehenden Spiralschnecke an der einen Seitenfläche ihres Endpaneels mit einer Schulter (42, 43) ausgebildet ist, die auf der Seite eines Mittelabschnitt davon hoch ist und auf der Außenendseite entlang der Windung des Wandkörpers niedrig ist, und
    wobei die andere der ortsfesten Spiralschnecke und der sich drehenden Spiralschnecke an einer Oberkante ihres Wandkörpers mit einem fehlausgerichteten Abschnitt (44, 45) ausgebildet ist, welcher der Schulter (42) an dem Endpaneel entspricht, wobei der fehlausgerichtete Abschnitt in mehrere Abschnitte unterteilt ist und auf der Seite einer Mitte der Windung niedrig ist und auf seiner Außenendseite hoch ist,
    wobei der Scrollverdichter dadurch gekennzeichnet ist,
    dass er eine in den mehreren Verdichtungskammern ausgebildete Zuführeinheit (17, 117, 517) umfasst, um das Kältemittel, das von außerhalb des Scrollverdichters (3, 103, 303, 403) zugeführt wird, zuzuführen und das Kältemittel dabei zu verdichten, und dadurch,
    dass das Kältemittel aus der Zuführeinheit zugeführt wird, während die mehreren Verdichtungskammern (C, C1, C2) miteinander über einen Freiraum zwischen der Schulter (42) und dem fehlausgerichteten Abschnitt (45) in Strömungsverbindung stehen, während die Schulter (42) und der fehlausgerichtete Abschnitt (45) in einem Abstand voneinander angeordnet sind.
  2. Scrollverdichter nach Anspruch 1, wobei die Zuführeinheit (17, 117, 517) eine Durchgangsöffnung ist, die in dem Endpaneel von mindestens einer der ortsfesten Spiralschnecke (23) und der sich drehenden Spiralschnecke (25) ausgebildet ist, und die Durchgangsöffnung an einer Position angeordnet ist, die mit den mehreren Verdichtungskammern (C, C1, C2) in Strömungsverbindung steht, während sie über einen Freiraum zwischen den mehreren Verdichtungskammern (C, C1, C2) miteinander in Strömungsverbindung stehen, während die Schulter (42) und der fehlausgerichtete Abschnitt (45) in einem Abstand voneinander angeordnet sind.
  3. Scrollverdichter nach Anspruch 1, wobei die Zuführeinheit (17, 117, 517) an einem Kontaktabschnitt der Schulter (42) mit Bezug zu dem fehlausgerichteten Abschnitt (45) angeordnet ist.
  4. Scrollverdichter nach Anspruch 1, wobei Dichtungselemente, die in Kontakt mit dem Endpaneel (23a) kommen, in einem Bereich an der Oberkante des Wandkörpers von dem fehlausgerichteten Abschnitt (45) in Richtung des Mittelabschnitts der Windung und einem Bereich von dem fehlausgerichteten Abschnitt in Richtung des äußeren Endes angeordnet sind, und die Zuführeinheit in einem Bereich des Endpaneels angeordnet ist, wo die Dichtungselemente nicht gleiten.
  5. Scrollverdichter nach einem der Ansprüche 1 bis 4, wobei eine Steuereinheit (119), welche die Zufuhr des Kältemittels von der Zuführeinheit zu den mehreren Verdichtungskammern (C, C1, C2) steuert, bereitgestellt ist und die Steuereinheit (119) veranlasst, dass das Kältemittel aus der Zuführeinheit zugeführt wird, während die Schulter und der fehlausgerichtete Abschnitt in einem Abstand voneinander angeordnet sind.
  6. Klimaanlage (1, 101, 301, 401, 501), umfassend:
    einen Scrollverdichter (3, 103, 303, 403) nach einem der Ansprüche 1 bis 5;
    eine Ölabscheidungseinheit (503) zum Trennen von Schmiermittel von durch den Scrollverdichter verdichtetem Kältemittel;
    einen Radiator (5) zum Abstrahlen von Wärme des durch den Scrollverdichter verdichteten Kältemittels;
    eine hochdruckseitige Dekompressionseinheit (7) zum Dekomprimieren des Drucks des abgestrahlten Kältemittels;
    eine niederdruckseitige Dekompressionseinheit (11) zum weiteren Dekomprimieren des dekomprimierten Kältemittels; und
    eine Wärmesenke (13), die bewirkt, dass das durch die niederdruckseitige Dekompressionseinheit dekomprimierte Kältemittel die Wärme absorbiert, wobei das durch die hochdruckseitige Dekompressionseinheit dekomprimierte Kältemittel und das durch die Ölabscheidungseinheit abgeschiedene Schmiermittel zu der Zuführeinheit des Scrollverdichters geleitet werden.
