Abstract

L'invention porte sur une pompe à chaleur et un circuit de chauffage d'eau intégrés pour le chauffage et le refroidissement des locaux et pour le chauffage de l'eau domestique. Le circuit comprend un premier échangeur de chaleur (20) pour l'eau domestique, un deuxième échangeur de chaleur (22) pour la source (source/puits de chaleur) qui possède un premier détendeur (24) dédié, et un troisième échangeur (30) pour le local avec un second détendeur (34) dédié. Le circuit a quatre modes de fonctionnement. Dans le premier mode, le local est refroidi et de la chaleur est renvoyée à la source. Dans le second mode, le local est chauffé tandis que la chaleur est absorbée par la source. Dans le troisième mode, le circuit absorbe de la chaleur de la source et chauffe la source d'eau. Dans un quatrième mode, la source d'eau est chauffée et le local est refroidi en même temps. Dans chaque mode, un échangeur de chaleur est inactif et la charge issue de l'échangeur de chaleur inactif est récupérée dans le côté aspiration du compresseur.
