Description

Die Erfindung bezieht sich auf eine Klimaanlage, insbesondere für ein Kraftfahrzeug, mit mehreren Komponenten, wie unter anderem einem Kompressor, einem Gaskühler und einem Druckbehälter, die mit einer Berstscheibe abzusichern sind.The The invention relates to an air conditioning system, in particular for a motor vehicle, with several components, such as a compressor, a gas cooler and a pressure vessel, the are to be secured with a rupture disc.

Klimaanlagen zur Klimatisierung eines beliebigen Innenraums sind im Stand der Technik in verschiedenen Ausführungsformen bekannt. Sie umfassen verschiedene Komponenten, die über rohrartige Verbindungsleitungen miteinander in Verbindung stehen, wobei die Komponenten bzw. Rohrleitungen beispielsweise mit Hilfe von Fittings, d.h. Verschraubungen, miteinander gekoppelt sind.air conditioning for the air conditioning of any interior are in the state of Technology in different embodiments known. They include various components that connect via tubular connecting pipes communicate with each other, wherein the components or pipes, for example with the help of fittings, i. Fittings, coupled together are.

Zur Steigerung der Kälteleistung einer Klimaanlage ist es bekannt, dass das verwendete Kältemittel, beispielsweise Kohlendioxyd, unter hohem Druck steht, wobei in einem Hochdruckteil der Klimaanlage Drücke von bis zu 160000 hPa herrschen können. In einem Expansionsorgan der Klimaanlage, in dem die eigentliche Kälteleistung erzeugt wird, wird das Kältemittel auf einen Druck von beispielsweise 30000 hPa entspannt. Mit einem Kompressor wird das Kältemittel wiederum verdichtet und gegebenenfalls in einem Druckbehälter gespeichert. In einem Gaskühler wird das beim Komprimieren erhitzte Gas abgekühlt.to Increase in cooling capacity an air conditioning unit it is known that the refrigerant used, For example, carbon dioxide, is under high pressure, in one High pressure part of the air conditioning Pressures of up to 160000 hPa. In an expansion organ the air conditioning system, in which the actual cooling capacity is generated, is the refrigerant relaxed to a pressure of, for example, 30,000 hPa. With a Compressor becomes the refrigerant in turn compacted and optionally stored in a pressure vessel. In a gas cooler the gas heated during compression is cooled down.

Weiterhin ist es üblich, derartige Klimaanlagen mit einer Sicherheitseinrichtung, unter anderem in Form eines Überdruck- oder eines Ablassventils, zu versehen, um das Kältemittel bei einem Defekt der Klimaanlage kontrolliert ablassen zu können, wodurch das Bersten von Komponenten, insbesondere im Fahrzeuginnenraum, vermieden ist.Farther it is usual, Such air conditioning systems with a safety device, including in Form of overpressure or a drain valve, to provide the refrigerant in the event of a defect the air conditioning controlled to be able to drain, causing the bursting of Components, especially in the vehicle interior, is avoided.

In einfacher Weise ist eine derartige Sicherheitseinrichtung in Form einer Berstscheibe ausgeführt, d.h. einem dünnen Metallplättchen, das in eine entsprechend ausgebildete Passung im Rohrleitungssystem eingesetzt ist. Dieses Metallplättchen bildet eine Sollbruchstelle, da es bei Überschreiten eines definierten Drucks im Rohrleitungssystem der Klimaanlage birst und zwar infolge der auf das Metallplättchen einwirkenden zu großen Druckkräfte.In simple way is such a safety device in the form a rupture disc running, i.e. a thin one Metal plates, in a suitably trained fit in the piping system is used. This metal plate forms a predetermined breaking point, as it exceeds a defined pressure in the piping system of the air conditioning bursts and although due to the pressure acting on the metal plate too large pressure forces.

Die WO 2004/002764 A1 offenbart eine Klimaanlage mit einer Berstscheibeneinrichtung, die nicht nur unter einem zu großen Druck in der Klimaanlage birst, sondern auch ferngesteuert zum Bersten gebracht werden kann. Beispielsweise kann die Berstscheibe über einen Heizdraht aufgeschmolzen werden, um das Kältemittel, wenn es gewünscht ist, aus der Klimaanlage entweichen zu lassen. Als nachteilig hierbei hat sich erwiesen, dass eine derartige Klimaanlage technisch relativ aufwändig ist und bei der Produktion erhebliche Kosten anfallen.The WO 2004/002764 A1 discloses an air conditioning system with a rupture disk device, not just under too much pressure in the air conditioning burst, but can also be ruptured remotely controlled. For example, the rupture disk can be melted over a heating wire, to the refrigerant, if desired is to let escape from the air conditioner. As a disadvantage here It has been proven that such an air conditioner is technically relatively costly is and costs incurred in production considerable.

Ausgehend von diesem Stand der Technik ist der Fachmann vor die Aufgabe gestellt, eine Klimaanlage der eingangs genannten Art zu schaffen, die einen einfachen konstruktiven Aufbau aufweist und günstig herstellbar ist.outgoing From this state of the art, the skilled person is faced with the task, to provide an air conditioning of the type mentioned, the one has simple structural design and is inexpensive to produce.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Berstscheibe in eine der Komponenten integriert ist.According to the invention Task solved by that the rupture disk is integrated in one of the components.

Der Kerngedanke der Erfindung besteht darin, eine an sich bekannte Berstscheibe zur Verhinderung des Entstehens eines Überdrucks in einer Klimaanlage nicht als separates Bauteil auszuführen, sondern in eine der bereits in der Klimaanlage vorhanden Komponenten zu integrieren. Somit entfällt insbesondere bei der Montage der Aufwand zum Einsetzen der Berstscheibe in eine separate Passung, beispielsweise an einer Rohrleitung, der Klimaanlage. Im Rahmen der Erfindung kann die Berstscheibe in eine beliebige Komponente der Klimaanlage, bevorzugt jedoch in eine der im Folgenden beschriebenen Komponenten, integriert sein.Of the The core idea of the invention is a rupture disk known per se for preventing the occurrence of overpressure in an air conditioner not as a separate component, but in one of the already in the air conditioning system to integrate components. This eliminates in particular during assembly of the effort to insert the rupture disc in a separate fit, for example on a pipeline, the air conditioning. In the context of the invention, the rupture disk in any Component of the air conditioning, but preferably in one of the following be described components, integrated.

Zweckmäßigerweise ist die Berstscheibe in eine Sicherheitseinrichtung, wie ein Überdruck- oder Ablassventil, der Klimaanlage integriert. Derartige Sicherheitseinrichtungen sind zur Betriebssicherheit der Klimaanlage unerlässlich, so dass durch das Integrieren der Berstscheibe in diese Sicherheitseinrichtungen die Zahl der benötigten Bauteile zur Herstellung der Klimaanlage minimiert ist.Conveniently, is the rupture disc in a safety device, such as an overpressure or drain valve, the air conditioning integrated. Such safety devices are essential for operational safety of the air conditioning system, so by integrating the rupture disk into these safety devices the number of needed Components for the production of the air conditioning is minimized.

Alternativ ist die Berstscheibe in ein Expansionsorgan der Klimaanlage integriert, beispielsweise in eine Drossel, in der das unter hohem Druck stehende Kältemittel auf einen niedrigeren Druck entspannt wird.alternative the rupture disk is integrated into an expansion element of the air conditioning system, For example, in a throttle in which the high pressure refrigerant is relaxed to a lower pressure.

Weiterhin ist die Berstscheibe alternativ in einem Kompressor der Klimaanlage integriert, in dem das Kältemittel wiederum unter hohen Druck gesetzt wird.Farther the rupture disc is alternatively in a compressor of the air conditioner integrated, in which the refrigerant again put under high pressure.

Ferner ist die Berstscheibe alternativ in einem Fitting zwischen zwei Komponenten oder Bauteilen bzw. Rohrleitungen der Klimaanlage integriert. Beispielsweise kann eine derartige Berstscheibe in eine Verschraubung an einer Rohrleitung integriert werden.Furthermore, the rupture disk is alternatively integrated in a fitting between two components or components or piping of the air conditioning system. For example, such a rupture disk can be integrated into a screwed connection to a pipeline become.
