L'invention concerne un condenseur (7) qui communique avec un évaporateur (8) par l'intermédiaire d'un tuyau de condensat à travers une pompe de circulation (4). L'évaporateur (8) communique ensuite avec un second détendeur (2) par l'intermédiaire d'un canal de vapeur. Le second détendeur (2) communique également avec un échangeur de chaleur haute température (5) par l'intermédiaire du canal de vapeur à travers un second échangeur de chaleur haute température (6). Un compresseur (3) communique avec l'échangeur de chaleur haute température (5) par l'intermédiaire du canal de vapeur. L'échangeur de chaleur haute température (5) communique également avec un détendeur (1) par l'intermédiaire du canal de vapeur. Le détendeur (1) communique également avec l'évaporateur (8) par l'intermédiaire d'un canal de vapeur basse pression, et l'évaporateur (8) communique ensuite respectivement avec le compresseur (3) et le condenseur (7) par l'intermédiaire du canal de vapeur basse pression. L'échangeur de chaleur haute température (5) et le second échangeur de chaleur haute température (6) communiquent respectivement avec l'environnement externe par l'intermédiaire d'un canal de milieu de source de chaleur. Le condenseur (7) communique également avec l'environnement externe par l'intermédiaire d'un canal de milieu de refroidissement. Le détendeur (1) et le second détendeur (2) sont reliés au compresseur (3) et transmettent de l'énergie.
