Abstract

Cette invention concerne un système de pompe de réfrigération ou de chauffage comprenant un évaporateur (23), un compresseur (20), un échangeur thermique (21) refroidi par air et rejetant de la chaleur, ainsi qu'un dispositif d'expansion (22) connecté en circuit fermé et fonctionnant selon un cycle à compression de vapeur transcritique. L'échangeur thermique à rejet de chaleur (21) est refroidi par la circulation/convection ascendante naturelle de l'air. Selon un mode de réalisation préféré, l'échangeur thermique (21) est construit dans une conduite ou un manchon d'air (11), ce qui favorise la circulation naturelle de l'air par effet de cheminée.
