Abstract

L'invention concerne un procédé de commande d'une vanne de détente électronique (EEV) dans un conditionneur d'air à l'aide d'un compresseur, ledit procédé comprenant les étapes consistant: (a) à ouvrir l'EEV complètement lorsqu'une énergie est appliquée sur le conditionneur d'air en mode d'attente; (b) à fermer l'EEV complètement lorsque le conditionneur d'air démarre une opération de refroidissement ou de chauffage; (c) à calculer une charge de chaleur intérieure; (d) à calculer une fréquence d'impulsion d'ouverture de référence de l'EEV; et (e) à commander de manière progressive une fréquence d'impulsion d'ouverture de l'EEV en fonction de la fréquence d'impulsion d'ouverture de référence de l'EEV. La fréquence d'impulsion de référence de l'EEV est commandée de manière progressive jusqu'à ce qu'elle atteigne la fréquence d'impulsion d'ouverture de référence de l'EEV.
