Abstract

L'invention propose un circuit de climatisation fonctionnant selon un cycle supercritique comprenant un compresseur (14), un refroidisseur de gaz (11), un échangeur interne (9), un module de détente (12) et un évaporateur (13) parcourus dans cet ordre par un fluide réfrigérant. Le circuit de climatisation comporte en outre :-une branche de dérivation de fluide (200) dont l'entrée est reliée à un point choisi du circuit (1) où le fluide réfrigérant se trouve à l'état essentiellement gazeux, et- un dispositif de régulation d'écoulement de fluide (15) apte à ajuster la proportion de fluide à envoyer dans la branche de dérivation en fonction de la température de décharge du fluide réfrigérant à la sortie du compresseur.
