Abstract

L'invention a pour objet une méthode de commande d'un organe de détente (6) constitutif d'une boucle de climatisation (1). Cette dernière (1) comprend en outre au moins un compresseur (3), un refroidisseur de gaz (4) et un évaporateur (7) destiné à refroidir un flux d'air (2). L'organe de détente (6) comporte une section de passage X variable pour permettre une détente contrôlée d'un fluide réfrigérant supercritique circulant à l'intérieur de ladite boucle (1). L'organe de détente (6) est contrôlé par des moyens électroniques (11) aptes à prendre en compte au moins une première information Tsr relative à une température du fluide réfrigérant en sortie du refroidisseur de gaz (4) pour calculer une valeur de ladite section de passage X. La méthode consiste à prendre aussi en compte une deuxième information S relative à une surchauffe en sortie de l'évaporateur (7), pour calculer la valeur de ladite section de passage X.
