Abstract

Die vorliegende Erfindung betrifft eine Laborzentrifuge mit einem Kompressorkühlkreislauf (5) und ein Verfahren zu m Betrieb einer Laborzentrifuge mit einem Kompressorkühlkreislauf (5). Die erfindungsgemäße Laborzentrifuge weist hinsichtlich der Kühlleistung einen höheren Wirkungsgrad auf als vergleich bare Zentrifugen. Dies ist mit nahezu keiner bzw. einer nur unwesentlich höheren Leistungsaufnahme verbunden. Außerdem ist der Bauraum der erfindungsgemäßen Laborzentrifuge gegen über vergleichbaren Laborzentrifuge nicht vergrößert.
