Abstract

L'invention concerne un système de climatisation, un climatiseur et un procédé de climatisation. Le système de climatisation comprend un échangeur de chaleur intérieur, un moyen d'étranglement (4) et un échangeur de chaleur extérieur (6) reliés en séquence. L'échangeur de chaleur intérieur et l'échangeur de chaleur extérieur (6) sont tous les deux reliés à un compresseur (9) au moyen d'une soupape à quatre voies (7). Un échangeur de chaleur (3) est relié entre le moyen d'étranglement (4) et l'échangeur de chaleur intérieur, et l'échangeur de chaleur extérieur (6) est relié à la soupape à quatre voies (7) au moyen de l'échangeur de chaleur (3). L'énergie thermique dans un fluide frigorigène évacué de l'échangeur de chaleur intérieur peut être recyclée au moyen d'un échange de chaleur entre le fluide frigorigène évacué de l'échangeur de chaleur intérieur et un fluide frigorigène évacué de l'échangeur de chaleur extérieur (6). À l'aide de l'augmentation de la température du fluide frigorigène évacué de l'échangeur de chaleur extérieur (6) tandis que le fluide frigorigène évacué de l'échangeur de chaleur intérieur est super-refroidi, la température de l'air de retour du compresseur (9) est augmentée, de sorte que la température d'échappement d'air du compresseur (9) soit augmentée, optimisant ainsi la capacité de chauffage globale du climatiseur.
