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.The invention relates to an air conditioning circuit through which a refrigerant fluid operates in supercritical mode, in particular of the CO2 type, in which at least one of the connecting ducts (24, 26, 28) extending in part of the circuit between the gas cooler (12) and the evaporator (18) has an internal diameter which is between 3 and 5 mm. The invention applies in particular to air conditioning circuits for motor vehicles.
