Abstract

La présente invention a trait à un système de génération-absorption de troisième type et à une pompe à chaleur à absorption régénératrice de troisième type. Le système de génération-absorption de troisième type est constitué d'un premier générateur (1), d'un deuxième générateur (2), d'un troisième générateur (3), d'un premier absorbeur (4), d'un deuxième absorbeur (5), d'un troisième absorbeur (6), d'une première pompe de solution (7), d'une deuxième pompe de solution (8), d'une troisième pompe de solution (9), d'un premier échangeur de chaleur de solution (10), d'un deuxième échangeur de chaleur de solution (11) et d'un troisième échangeur de chaleur de solution (12). Le premier générateur (1), le deuxième générateur (2) et le troisième absorbeur (6) sont utilisés de manière à réaliser un processus de génération de solution d'excitation à faible température doté d'une procédure de récupération. Le troisième générateur (3) et le deuxième absorbeur (5) sont utilisés de manière à réaliser un processus de génération de solution d'excitation à température élevée. Le premier absorbeur (4) et le deuxième absorbeur (5) sont utilisés de manière à dissiper la puissance calorifique vers l'extérieur. Sur la base du système, la pompe à chaleur à absorption régénératrice de troisième type est formée en ajoutant des condensateurs (13), des évaporateurs (14), des pompes hydrauliques de fluide frigorigène (15) et ainsi de suite.
