Abstract (en)

The refrigeration installation has separate refrigerator and freezer circuits each containing a compressor (C1/C2,C3/C4/C5/C with the pressure lines (8,16) leading from the latter combined before a condenser (V) and coupled via a selectively blocked def line (30) with the suction line (10) of the compressor (C3/C4/C5/C6) for the freezer circuit.

Abstract (de)

Kälteanlage zur Kühlung von wenigstens einem Kälteverbraucher mittels eines Normalkühlkreislaufes und zur Kühlung von wenigstens einem Kälteverbraucher mittels eines Tiefkühlkreislaufes, wobei jeder der Kreisläufe eine Verdichtereinheit aufweist, lediglich ein Verflüssiger vorgesehen ist und die Druckleitungen von den Verdichtereinheiten vor dem Verflüssiger zusammengeführt sind. Erfindungsgemäß sind die Druckleitungen (8, 16) von den Verdichtereinheiten (C1/C2, C3/C4/C5/C6) über eine Abtauleitung (30), die vorzugsweise absperrbar (e) ausgebildet ist, mit der Saugleitung (10) der Verdichtereinheit (C3/C4/C5/C6) des Tiefkühlkreislaufes verbunden. Dadurch wird ein neuartiges Abtauverfahren ermöglicht, bei dem der NormalkühlVerbundsatz bzw. die Verdichtereinheit C1/C2 im Wärmepumpenbetrieb arbeitet. Für den gesamten Tiefkühlbereich kann durch die Realisierung der Erfindung eine deutlich geringere Abtauzeit gegenüber der elektrischen Abtauung erreicht werden. <IMAGE>
