Abstract

L'invention concerne une boucle de climatisation (B) pour un dispositif de climatisation d'air dans laquelle circule un fluide supercritique et comprenant au moins un compresseur (1), un refroidisseur de gaz (4), un dispositif de détente (5) et un évaporateur (2), caractérisé en ce qu'une vanne (8) est installée à l'entrée du compresseur (1), ladite vanne (8) interdisant le passage du fluide supercritique à l'intérieur du compresseur (1) lorsque la pression de la boucle de climatisation est supérieure à une pression dite plafond (PPD).The invention relates to an air conditioning loop (B) for an air conditioning device in which a supercritical fluid circulates and comprising at least one compressor (1), a gas cooler (4), an expansion device (5) and an evaporator (2), characterized in that a valve (8) is installed at the inlet of the compressor (1), said valve (8) preventing the passage of the supercritical fluid inside the compressor (1) when the pressure of the air conditioning loop is higher than a so-called ceiling pressure (PPD).
