Abstract
L'invention propose une installation de climatisation, notamment pour véhicule à moteur, munie d'un régulateur de climatisation et d'un circuit de fluide frigorigène fonctionnant selon un cycle supercritique. Le circuit comportant un compresseur, un organe de refroidissement, un orifice de détente dont le degré d'ouverture varie en fonction de l'intensité d'un signal de commande, un évaporateur. Le régulateur de climatisation est apte à commander le degré d'ouverture initial de l'orifice de détente au démarrage de la climatisation à partir d'une valeur initiale prédéfinie du signal de commande. Le dispositif électronique de commande est propre à calculer la valeur initiale du signal de commande (PWM_init) à partir:- d'une estimation de la valeur initiale de la température du fluide à l'entrée de l'organe de détente (Tin_init), de la valeur initiale de la pression du fluide à la sortie de l'organe de détente (Pout_init) et de la valeur initiale du débit de fluide frigorigène dans l'orifice de détente (mCO2_OD_init), et- d'une estimation de la valeur de la pression du fluide en entrée de l'orifice de détente (Pin_visée) qui maximise le coefficient de performance, dite valeur visée de la haute pression.
