Abstract

L'invention propose un dispositif de détente, destiné à être installé dans un circuit de climatisation fonctionnant avec un fluide réfrigérant (FR) de type supercritique. Le dispositif de détente (12) comprend un corps (120) propre à être traversé par le fluide réfrigérant, ayant un compartiment d'entrée (1210) dans lequel arrive le fluide réfrigérant et un compartiment de sortie (1230) par lequel sort le fluide réfrigérant. Le dispositif de détente comporte en outre un ensemble de moyens de détente propres à faire passer le fluide réfrigérant du compartiment d'entrée (1210) au compartiment de sortie (1230). Ces moyens de détente comprennent :- des moyens de détente variable (1212) comprenant un premier orifice (34) et un pointeau (134) propre à faire varier la section de passage du premier orifice (34), et- des moyens de détente fixe comprenant un deuxième orifice (35) ayant une section de passage fixe.
