L'invention concerne un procédé d'amélioration de rendement par étalement de température, ledit procédé étant caractérisé en ce qu'un fluide de travail absorbe de la chaleur dans un échangeur de chaleur (1) et entraîne, en tant que gaz propulsif ou vapeur propulsive dans une pompe à jet (2), un gaz ou une vapeur d'aspiration dans un tube à tourbillonnement (3) monté en aval, le gaz ou la vapeur mixte dans le tube à tourbillonnement (3) étant décomposé en deux fractions de chaleur. La fraction de chaleur présentant la température la plus élevée est acheminée à l'évaporateur/au réchauffeur (4) d'un circuit de turbine (6) puis est réacheminée à l'échangeur de chaleur (1). La fraction de chaleur présentant la température la plus basse est acheminée au condenseur/dispositif de refroidissement (15) du circuit de turbine séparé et/ou à l'échangeur de chaleur (10) pour former un circuit de refroidissement, d'où elle est remise à disposition de la pompe à jet (2) en tant que gaz d'aspiration.
