Abstract

Die Erfindung betrifft ein Atemkreislaufgerät mit einer Atemkreisleitung, einem CO2-Absorber (6) in der Atemkreisleitung und mit einer Kühleinrichtung zur Kühlung des Atemgases nach Austritt aus dem CO2-Absorber. Erfindungsgemäß ist vorgesehen, dass die Kühleinrichtung eine Wärmepumpe mit einem Kompressor (33) zur Verdichtung eines Kühlmediums, einem Kondensator (30), der das verdichtete Kühlmedium aufnimmt, kühlt und dabei Wärme an die Umgebung abgibt, und mit einem Wärmetauscherkörper (8) aufweist, der das gekühlte Kühlmedium aufnimmt und in Wärmeleitungskontakt mit einem Abschnitt der Atemkreisleitung steht.
