Abstract

Die Erfindung betrifft eine Kälteanlage mit wenigstens einem Normalkühlkreislauf und wenigstens einem Tiefkühlkreislauf, wobei die Kreisläufe miteinander verschaltet und lediglich ein Verflüssiger vorgesehen ist und der Tiefkühlkreislauf eine wenigstens zweistufige Verdichtereinheit aufweist, sowie ein Verfahren zum Betreiben einer derartigen Kälteanlage.
Erfindungsgemäß steht die Saugseite des Normalkühlkreislaufes mit der oder einer der Zwischendruckseiten des Tiefkühlkreislaufes in Wirkverbindung; dies wird vorzugsweise mittels wenigstens einer Verbindungsleitung (20) realisiert.
Sofern zumindest einer Verdichterstufe des Normalkühlkreislaufes und einer Verdichterstufe des Tiefkühlkreislaufes, wobei es sich nicht um die erste Verdichterstufe handelt, Saugsammelbehälter (S2, S4) vorgeschaltet sind, stehen diese miteinander in Wirkverbindung.
