La présente invention concerne un système de pompe à chaleur et, plus spécifiquement, la production d'eau chaude d'un système de pompe à chaleur de type air-air ainsi qu'une structure de dégivrage et refroidissement pour un échangeur thermique extérieur, permettant de simplifier la structure de ce dernier, d'augmenter l'efficacité d'utilisation d'une source de chaleur gratuite, d'augmenter le coefficient de performance à un niveau satisfaisant et de générer de l'eau chaude à tout moment. Le système selon l'invention comprend: un cycle de congélation de base (10) pour relier les composants principaux avec une conduite pour fluide frigorigène; un circuit de chauffage à eau chaude (20) monté entre un compresseur (11) et un robinet à quatre voies (12) de la conduite pour fluide frigorigène, un moyen de dégivrage (30) pour former un condenseur (32) entre un détendeur assurant le refroidissement (14) et un détendeur assurant le chauffage (15) de la conduite pour fluide frigorigène, entourant le condenseur (32) avec un réservoir de stockage de chaleur (33) dans lequel est introduit un milieu de stockage thermique, monter un échangeur thermique auxiliaire (34) sur l'échangeur thermique extérieur (16) de sorte que le réservoir de stockage de chaleur (33) et l'échangeur thermique auxiliaire (34) soient connectés pour former un circuit fermé de milieu de stockage de chaleur; un moyen de dégivrage et de refroidissement (40) pourvu d'un échangeur thermique (41) formé sur une conduite de milieu chauffant (43) à l'arrière d'une pompe de circulation (36) pour milieu de stockage de chaleur d'une conduite d'alimentation (35a) en milieu de stockage de chaleur, et présentant un réservoir de stockage (42) de source de chaleur gratuite formé sur l'échangeur thermique (41) et formant également un circuit fermé de milieu de stockage de chaleur par raccordement dudit réservoir (42) avec un circuit fermé de milieu de stockage de chaleur formé sur le moyen de dégivrage (30), ce qui permet de faire circuler le milieu de chauffage vers l'échangeur thermique auxiliaire (34); et un moyen d'augmentation des performances (50) monté sur le côté sortie de l'échangeur thermique (41) de la conduite (43) et entre l'échangeur thermique extérieur (16) et le robinet à quatre voies (12) de la conduite pour fluide frigorigène (17).
