Abstract

L'invention concerne un circuit de climatisation parcouru par un fluide réfrigérant fonctionnant en mode supercritique, en particulier du type CO2, dans lequel l'un au moins des conduits de liaison (24, 26, 28) s'étendant dans une partie du circuit comprise entre le refroidisseur de gaz (12) et l'évaporateur (18) a un diaimètre interne qui est compris entre 3 et 5 mm. L'invention s'applique notamment aux circuits de climatisation pour véhicules automobiles.
