Abstract

Um eine Kälteanlage umfassend einen Kältemittelkreislauf, mit einem hochdruckseitigen kältemittelkühlenden Wärmetauscher, mit einer Expansionskühleinrichtung, mit einem Reservoir für den Hauptmassenstrom, mit mindestens einer Normalkühlstufe, mit einer einen Tiefkühlgesamtmassenstrom aus dem Reservoir entnehmenden Tiefkühlstufe und mit mindestens einer in dem Kältemittelkreislauf angeordneten Kältemittelverdichtereinheit, derart zu verbessern, dass diese einen besseren Wirkungsgrad aufweist, wird vorgeschlagen, dass die Tiefkühlstufe zur weiteren Abkühlung des Tiefkühlgesamtmassenstroms eine Tiefkühlexpansionskühleinrichtung aufweist, die im aktiven Zustand den Tiefkühlgesamtmassenstrom abkühlt und dabei einen dem Tiefkühlexpansionsorgan zugeführten Tiefkühlhauptmassenstrom sowie einen Tiefkühlzusatzmassenstrom erzeugt.
