Abstract

Die Erfindung betrifft eine Vorrichtung zur sicheren Durchführung eines linksdrehenden thermodynamischen Clausius-Rankine-Kreisprozesses mittels eines entzündlichen Arbeitsfluids, welches im gasförmigen Zustand unter Atmosphärenbedingungen schwerer als Luft ist und in einem geschlossenen, hermetisch dichten Arbeitsfluidumlauf geführt wird, aufweisend mindestens einen Verdichter für Arbeitsfluid, mindestens eine Enspannungseinrichtung für Arbeitsfluid, mindestens zwei Wärmeübertrager für Arbeitsfluid mit jeweils mindestens zwei Anschlüssen für Wärmeüberträgerfluide, ein geschlossenes Gehäuse, welches alle am geschlossenen Arbeitsfluidumlauf angeschlossenen Einrichtungen umfasst, weitere Einrichtungen umfassen kann, und mit einem Adsorbens ausgekleidet ist, welches in der Lage ist, Arbeitsfluid zu adsorbieren, und mindestens eine weitere Sorptionseinrichtung vorgesehen wird, mit der das gesamte Arbeitsfluid bei Normalbedingungen adsorbiert werden kann, und mindestens eine Sicherheits-Kältemittelablass-Einrichtung vorgesehen wird.The invention relates to a device for safely performing a left-turning thermodynamic Rankine cycle using an inflammable working fluid, which is heavier than air in the gaseous state under atmospheric conditions and is conducted in a closed, hermetically sealed working fluid circuit, comprising at least one compressor for working fluid, at least a relaxation device for working fluid, at least two heat exchangers for working fluid, each with at least two connections for heat transfer fluids, a closed housing which comprises all devices connected to the closed working fluid circulation, further devices, and is lined with an adsorbent which is capable of working fluid to adsorb, and at least one further sorption device is provided with which the entire working fluid can be adsorbed under normal conditions, and at least one Safety refrigerant drain device is provided.
