Abstract

L’invention concerne une méthode de détermination du niveau de charge en fluide réfrigérant dans un circuit de refroidissement (1) pour système de climatisation embarqué dans laquelle la quantité totale de fluide réfrigérant sous forme gazeuse et liquide contenue dans les différents composants (2, 3, 4, 5 et 10) du système de climatisation est calculée seulement sur la base de données internes au circuit de refroidissement. Cette méthode est mise en œuvre par un module de détection de fuite sur un circuit de refroidissement d’un système de climatisation embarqué comprenant des capteurs (9, 11, 12, 13 et 14) pour mesurer des caractéristiques physiques du réfrigérant en différentes parties du circuit 1, et un contrôleur 8 apte à calculer le niveau de charge en réfrigérant contenu dans les différents composants (2, 3, 4, 5 et 10) du système de climatisation sur la base de données correspondant aux paramètres géométriques et techniques des différents composants du circuit de refroidissement, du type de réfrigérant utilisé et des caractéristiques physiques mesurées du réfrigérant.
