Abstract

Die vorliegende Erfindung bezieht sich auf eine Kälteanlage mit folgenden zu einem Kreisprozess für ein Kältemittel verbundenen Komponenten: einem Verdampfer (2), einem diesem in Strömungsrichtung des gasförmigen Kältemittels nachgeordneten inneren Wärmeaustauscher (3), einem Verdichter (4), einem Verflüssiger (5), welchem in Strömungsrichtung des nunmehr flüssigen Kältemittels der innere Wärmeaustauscher (3) nachgeschaltet ist, und einem dem inneren Wärmeaustauscher (3) in Strömungsrichtung des flüssigen Kältemittels nachgeordneten und dem Verdampfer (2) vorgeschalteten Expansionsventil (6), welches einen Überhitzungsfühler (11) aufweist. Die Erfindung ist dadurch gekennzeichnet dass das Expansionsventil (6) ein solches mit einer statischen Überhitzung ≤ 2 K ist und der Überhitzungsfühler (11) in Strömungsrichtung des Kältemittels hinter dem Verdampfer (2) und vor dem inneren Wärmeaustauscher (3) angeordnet ist.
