Abstract
Description
Die vorliegende Erfindung betrifft ein Fahrzeug mit einem Fahrgastraum und einem Kältemittelkreislauf gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to a vehicle having a passenger compartment and a refrigerant circuit according to the generic term of claim 1.
Aufgabe der Erfindung ist es, ein Fahrzeug mit einem Kältemittelkreislauf zu schaffen, bei dem sichergestellt ist, dass bei eventuellen Undichtigkeiten an Kopplungsstellen des Kältemittelkreislaufs dennoch kein Kältemittel in die Fahrgastraumatmosphäre gelangen kann.task the invention is to provide a vehicle with a refrigerant circuit, which ensures that any leaks Nevertheless, at coupling points of the refrigerant circuit no refrigerant into the passenger compartment atmosphere can get.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Fahrzeug mit einem Fahrgastraum und einem Kältemittelkreislauf, der eine Kopplungsstelle aufweist, an der zwei kältemittelführende Komponenten miteinander verbunden sind.starting point The invention relates to a vehicle with a passenger compartment and a Refrigerant circulation, having a coupling point, connected to the two refrigerant-carrying components together are.
Der Kern der Erfindung besteht darin, dass im Bereich innerhalb des Fahrgastraums eine Kopplungsstelle angeordnet ist, wobei die Kopplungsstelle von einer Schutzeinrichtung umschlossen ist, deren Inneres gegenüber der Fahrgastraumatmosphäre gasdicht abgedichtet ist und über eine Entlüftung mit der Atmosphäre außerhalb des Fahrgastraums in Fluidverbindung steht.Of the Core of the invention is that in the area within the Passenger compartment is arranged a coupling point, wherein the coupling point of a protective device is enclosed, the interior of the Passenger compartment atmosphere gas-tight is sealed and over a vent with the atmosphere outside the passenger compartment is in fluid communication.
Durch Verwendung einer derartigen Schutzeinrichtung können Kopplungsstellen von Kältemittelleitungen unabhängig von der Art des Kältemittels im Fahrgasraumbereich angeordnet werden. Bei einer eventuellen Undichtigkeit einer Kopplungsstelle kann das Kältemittel lediglich in den ”Raum”, der durch die Schutzeinrichtung begrenzt ist, entweichen, nicht aber in die Fahrgastraumatmosphäre. Aus dem Innenraum der Schutzeinrichtung kann das Kältemittel dann an die Umgebung entweichen, wodurch ein Eintrag von Kältemittel in den Fahrgastraum ausgeschlossen wird.By Use of such a protective device can coupling points of refrigerant pipes independently on the type of refrigerant be arranged in the passenger compartment area. In case of a possible leak a coupling point can be the refrigerant only in the "space" that through the protective device is limited, escape, but not in the Cabin atmosphere. From the interior of the protective device, the refrigerant can then escape to the environment, creating an entry of refrigerant is excluded in the passenger compartment.
Nach einer Weiterbildung der Erfindung weist die Entlüftung eine Entlüftungsleitung auf, die vom Innern der Schutzeinrichtung aus gesehen in Bezug auf die Schwerkraft fallend angeordnet ist. Dadurch ist sichergestellt, dass Kältemittel, welches ein höheres spezifisches Gewicht als Luft hat, selbsttätig aus dem Inneren der Schutzeinrichtung ”abfließen” kann.To a development of the invention, the vent has a vent line in relation to the inside of the protective device Gravity is arranged falling. This ensures that refrigerant, which is a higher one has specific weight as air, can automatically "flow" out of the interior of the protective device can.
Vorzugsweise ist die Entlüftungsleitung über ihre gesamte Länge fallend angeordnet. Dadurch wird vermieden, dass sich Kältemittel in einzelnen Abschnitten der Entlüftungsleitung ansammeln kann.Preferably is the vent line over her whole length arranged falling. This will avoid getting refrigerant can accumulate in individual sections of the vent line.
Als Entlüftungsleitung kann beispielsweise ein Schlauch, ein Rohr oder ein Kanal verwendet werden. Die Entlüftungsleitung kann flexibel oder im Wesentlichen starr ausgeführt sein.When vent line For example, a hose, a pipe or a duct can be used. The vent line may be flexible or substantially rigid.
