Abstract

Es wird ein Verfahren zur Umwandlung von thermischer in mechanische Energie mittels eines Rankine-Kreislaufs beschrieben, wobei
- das in dem Rankine-Kreislauf zirkulierende Arbeitsmittel vor dem Wärmetausch mit einem externen Medium auf einen Druck oberhalb seines kritischen Drucks gepumpt,
- im Wärmetausch mit dem externen Medium auf eine Temperatur oberhalb seiner kritischen Temperatur angewärmt wird, wobei die Temperatur wenigstens so hoch ist, dass das Arbeitsmittel ohne teilzukondensieren entspannt werden kann,
- das Arbeitsmittel entspannt und das entspannte Arbeitsmittel kondensiert wird.A method of converting thermal energy into mechanical energy by means of a Rankine cycle is described, wherein
the working fluid circulating in the Rankine cycle is pumped with an external medium to a pressure above its critical pressure before the heat exchange,
is heated in heat exchange with the external medium to a temperature above its critical temperature, wherein the temperature is at least so high that the working fluid can be relaxed without teilzukondensieren,
- The working fluid relaxed and the relaxed working fluid is condensed.

Erfindungsgemäß erfolgt die Regelung des maximalen Drucks des Arbeitsmittels mittels eines bzgl. des Mengenstromes des Arbeitsmittels (5) regelbaren Expanders (X1) und/oder einer bzgl. des Mengenstromes des Arbeitsmittels (1) regelbaren Pumpe (P1).
