Abstract

L'invention concerne une pompe à chaleur à absorption du premier type ayant une alimentation de chaleur à plusieurs extrémités, comportant un générateur (1), un premier absorbeur (2), un second absorbeur (3), un évaporateur à absorption (4), un condensateur (5), un évaporateur (6), une soupape d'étranglement (7), une pompe à fluide frigorigène liquide (8), une première pompe à solution (9), une seconde pompe à solution (10), un premier échangeur de chaleur de solution (11) et un second échangeur de chaleur de solution (12). Le second absorbeur (3) fournit une solution au générateur (1) et le générateur (1) fournit la solution au premier absorbeur (2). Le premier absorbeur (2) fournit la solution à l'évaporateur à absorption (4) et l'évaporateur à absorption (4) fournit la solution au second absorbeur (3). Le générateur (1) fournit de la vapeur de fluide frigorigène au condensateur (5) et le condensateur (5) fournit du fluide frigorigène liquide à l'évaporateur (6). L'évaporateur (6) fournit la vapeur de fluide frigorigène au premier absorbeur (2) et à l'évaporateur à absorption (4) respectivement, et l'évaporateur (6) fournit le fluide frigorigène liquide à l'évaporateur à absorption (4) et après absorption de la chaleur dans la vapeur de fluide frigorigène, fournit celle-ci au second absorbeur (3). Le premier absorbeur (2), le condensateur (5) et le second absorbeur (3) forment une alimentation de chaleur à plusieurs extrémités.
