Abstract

L'invention concerne un système d'absorption-génération récupérateur et une pompe à chaleur à absorption de second type récupératrice. Le système d'absorption-génération récupérateur comprend un générateur (1), un premier absorbeur (2), un deuxième absorbeur (3), un premier échangeur de chaleur de solution (4), un deuxième échangeur de chaleur de solution (5), une chambre de séparation de vapeur (6), une première pompe de solution (7) et une deuxième pompe de solution (8). Le générateur (1) communique, par l'intermédiaire de pipelines de solution concentrée, avec la première pompe de solution (7), le premier échangeur de chaleur de solution (4), le premier absorbeur (2) et la chambre de séparation de vapeur (6), tour à tour, et la chambre de séparation de vapeur (6) communique avec la deuxième pompe de solution (8), le deuxième échangeur de chaleur de solution (5) et le deuxième absorbeur (3), de la même manière, de même que par l'intermédiaire de pipelines de solution diluée, le deuxième absorbeur (3) communique avec le deuxième échangeur de chaleur de solution (5) et le premier absorbeur (2), tour à tour, et le premier absorbeur (2) communique avec le premier échangeur de chaleur de solution (4) et le générateur (1), de la même manière. En variante, le générateur (1) communique avec tour à tour, et le deuxième absorbeur communique, par l'intermédiaire de pipelines de solution concentrée, avec la première pompe de solution (7), le premier échangeur de chaleur de solution (4) et le premier absorbeur (2), tour à tour, et par l'intermédiaire de pipelines de solution diluée, le premier absorbeur (2) communique avec le premier échangeur de chaleur de solution (4) et le générateur (1), tour à tour, et le deuxième absorbeur (3) communique avec le deuxième échangeur de chaleur de solution (5), le premier absorbeur (2) et la chambre de séparation de vapeur (6) de la même manière, de même que par l'intermédiaire de pipelines de solution concentrée, la chambre de séparation de vapeur (6) communique avec la deuxième pompe de solution (8), le deuxième échangeur de chaleur de solution (5), le deuxième absorbeur (3), tour à tour. Le premier absorbeur (2) communique avec l'extérieur, respectivement, par l'intermédiaire de passages de vapeur réfrigérants et des pipelines à milieu chauffé. La chambre de séparation de vapeur (6) communique avec l'extérieur par l'intermédiaire de passages de vapeur réfrigérants.
