Abstract

L'invention appartient au domaine de la production d'énergie et peut notamment s'utiliser dans des moteurs fonctionnant selon un processus circulaire. Dans cette invention, on utilise en tant que fluide actif un mélange de substances ayant la forme d'une solution gaz / liquide, constituée de plusieurs composants qui se trouvent en équilibre en phases liquide et gazeuse. Dans la première phase de travail à une température initiale et une pression initiale, le fluide actif se dilate en effectuant un travail, et la chaleur est ensuite évacuée. La dilatation du fluide actif et l'évacuation subséquente de la chaleur sont effectuées jusqu'à une température à laquelle le fluide actif est séparé en phase gazeuse et en phase liquide. La phase liquide du fluide actif est séparée de la phase gazeuse et comprimée séparément. Après la compression, la phase liquide est réchauffée par l'amenée de chaleur et mélangée à la phase gazeuse jusqu'à ce qu'un fluide actif soit formé à une température initiale. Le cycle permet d'utiliser la chaleur basse température dans le fonctionnement d'une machine thermique.
