Abstract

Bei der Umwandlung thermischer Energie in mechanische Energie unter Nutzung eines Arbeitsmittels, das aus einem Stoffgemisch mit zumindest zwei Stoffen besteht, die unterschiedliche Siede- und Kondensationstemperaturen aufweisen, und das einem Kondensator (8) zugeführt und darin kondensiert wird, besteht das Problem, dass durch eine Entmischung des Stoffgemisches vor dem Kondensator in eine flüssige Phase und eine dampfförmige Phase der Kondensationsdruck im Kondensator steigt und somit der Wirkungsgrad für die Erzeugung der mechanischen Energie sinkt. Dies wird erfindungsgemäss dadurch verhindert, dass vor oder bei der Kondensation des Arbeitsmittels in dem Kondensator (8) die flüssige Phase des Arbeitsmittels mit der dampfförmigen Phase des Arbeitsmittels vermischt wird. Hierdurch kann wieder ein homogenes Stoffgemisch erzeugt werden, das bei einem niedrigeren Druck kondensiert als das entmischte Arbeitsmittel, womit Wirkungsgradeinbussen verhindert werden. Bevorzugte Anwendungen liegen in der Nutzung der Wärmeenergie von Niedertemperaturquellen wie z.B. geothermischer Fluide, industrieller Abwärme oder Abwärme von Verbrennungskraftmaschinen.
