Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Behandlung des Kältemittels, das in einem transkritischen Klimakreislauf zirkuliert, enthaltend: Kompressor (1), Gaskühler (3), Verdampfer, (Wärmetauscher) und Expansionsorgan und dabei eine Hochdruckseite und Niederdruckseite durchläuft, in denen das Kältemittel unterschiedliche Temperatur aufweist, wobei die Vorrichtung ein flaches Mehrkammerrohr (10) umfasst, durch das die eine Seite strömt und das in einem Behälter (20) angeordnet ist, durch den die andere Seite strömt, um als Zwischenwärmetauscher zu dienen, wobei in dem Behälter (20) eine Akkumulatorkammer (21) und eine Wärmetauscherkammer (22) ausgebildet ist. Eine besonders kompakte und wirksame Vorrichtung wird erfindungsgemäß dadurch erreicht, dass der das Mehrkammerrohr (10) enthaltende Behälter (20) mit einem Sammelrohr (4) eines Wärmetauschers (3) verbunden ist, wobei in der Akkumulatorkammer (21) ein Trockner (24) angeordnet ist und wobei sich die Akkumulatorkammer (21) und die Wärmetauscherkammer (22) etwa über die Länge des schlanken Behälters (20) erstrecken.The invention relates to a device for the treatment of the refrigerant, which circulates in a transcritical air conditioning circuit comprising: compressor (1), gas cooler (3), evaporator, (heat exchanger) and expansion element and thereby passes through a high pressure side and low pressure side, in which the refrigerant different temperature, the apparatus comprising a flat multi-chamber tube (10) through which one side flows and which is arranged in a container (20) through which the other side flows to serve as an intermediate heat exchanger, wherein in the container ( 20) an accumulator chamber (21) and a heat exchanger chamber (22) is formed. A particularly compact and effective device is inventively achieved in that the container (20) containing the multi-chamber tube (10) is connected to a collecting tube (4) of a heat exchanger (3), wherein a dryer (24) is arranged in the accumulator chamber (21) and wherein the accumulator chamber (21) and the heat exchange chamber (22) extend approximately the length of the slender container (20).

Eine besonders herstellungsfreundliche Vorrichtung ergibt sich erfindungsgemäß dadurch, dass der Behälter (20) als schlanker Hohlkörper mit wenigstens einer Längswand (26) oder mit Halterungen (27) zum Halten wenigstens einer eingesetzten Längswand ausgebildet ist, wobei die wenigstens eine Längswand (26) wenigstens eine Öffnung (31) aufweist, damit das Kältemittel die Kammern (21, 22) durchströmen kann und wobei sich die Akkumulatorkammer (21) und die Wärmetauscherkammer (22) etwa über die Länge des schlanken Behälters (20) erstrecken.

Figure imgaf001
A particularly production-friendly device results according to the invention in that the container (20) as a slender hollow body with at least one longitudinal wall (26) or with holders (27) for holding at least one inserted longitudinal wall is formed, wherein the at least one longitudinal wall (26) at least one Opening (31), so that the refrigerant can flow through the chambers (21, 22) and wherein the accumulator chamber (21) and the heat exchanger chamber (22) extend approximately the length of the slender container (20).
