Abstract

Une pompe à chaleur à absorption du premier type dotée d'une alimentation en chaleur à extrémités multiples comprend un premier générateur (1), un second générateur (2), un premier absorbeur (3), un second absorbeur (4), un premier condensateur (5), un second condensateur (6), un évaporateur (7), une première soupape d'étranglement (8), une seconde soupape d'étranglement (9), une première pompe à solution (10), une seconde pompe à solution (11), un premier échangeur de chaleur de solution (12) et un second échangeur de chaleur de solution (13). Le premier absorbeur (3) fournit une solution au second absorbeur (4), le second absorbeur (4) fournit une solution au premier générateur (1), le premier générateur (1) fournit une solution au second générateur (2), le second générateur (2) fournit une solution au premier absorbeur (3), le premier générateur (1) fournit de la vapeur cryogénique au premier condensateur (5), le second générateur (2) fournit de la vapeur cryogénique au second absorbeur (4) et au second condensateur (6), le premier condensateur (5) et le second condensateur (6) fournissent une solution cryogénique à l'évaporateur (7) et l'évaporateur (7) fournit de la vapeur cryogénique au premier absorbeur (3), ce qui permet de former la pompe à chaleur à absorption du premier type dotée d'une alimentation en chaleur à extrémités multiples. La pompe à chaleur a un effet bénéfique sur l'amélioration de l'indice de performance et sur l'utilisation intensive de la charge thermique d'entraînement.
