Abstract

Kältemittelverdichteranlage umfassend mindestens drei parallel zwischen einer Ansaugleitung und einer Druckleitung angeordnete Verdichter, von denen jeder eine Schmiermittelsumpfeinheit aufweist, wobei die Verdichter im Betrieb so arbeiten, dass die jeweiligen Drücke in den jeweiligen Schmiermittelsumpfeinheiten der jeweiligen Verdichter eine Druckkaskade ergeben, gemäß welcher die Verdichter in einer definierten Kaskadenreihenfolge einen schrittweise geringfügig niedriger werdenden Druck in der jeweiligen Schmiermittelsumpfeinheit aufweisen, wobei die Schmiermittelsumpfeinheiten miteinander entsprechend der Kaskadenreihenfolge zum Schmiermitteltransport mit einem Schmiermittelleitungssystem verbunden sind und wobei jede Schmiermittelsumpfeinheit einen Anschluss aufweist, mit welchem ein Einsatzelement verbunden ist, welches einerseits eine Verbindung zu dem Schmiermittelleitungssystem herstellt und andererseits so ausgebildet ist, dass es der jeweiligen Schmiermittelsumpfeinheit ein Schmiermittelstandsniveau vorgibt, ab welchem ein Schmiermitteltransport zu der in der Kaskadenreihenfolge nächstfolgenden Schmiermittelsumpfeinheit erfolgt.
