Abstract

Die Erfindung betrifft einen Kältemittelkreislauf (10), umfassend mindestens einen Kältemittelverdichter (12), welcher an einem Sauganschluss zugeführtes Kältemittel auf Hochdruck verdichtet, so dass an einem Druckanschluss ein auf Hochdruck verdichteter Verdichtermassenstrom des Kältemittels austritt, mindestens einen hochdruckseitigen wärmeabgebenden Wärmeübertrager (22) mit einem Eingang, welchem der Kältemittelkreislauf den Verdichtermassenstrom zuführt, und mit einem Ausgang, aus welchem ein gekühlter Gesamtmassenstrom von Kältemittel austritt, mindestens eine Expansionseinheit (32), und mindestens eine Kühlstufe (62) mit mindestens einem wärmeaufnehmenden Wärmeübertrager, welchem der Kältemittelkreislauf einen von dem von der Expansionseinheit expandierten Expansionsdruckmassenstrom umfassen Hauptmassenstrom zuführt, sowie eine dem Kältemittelkreislauf zugeordnete eine Betriebsanpassungseinheit (230).
