Abstract

La présente demande se rapporte au domaine technique des appareils ménagers intelligents et divulgue un procédé de commande d'un climatiseur. Le procédé comprend les étapes consistant à : lorsqu'un climatiseur est démarré, commander l'ouverture d'une vanne de détente électronique jusqu'au degré d'ouverture maximal ; et lorsque la vanne de détente électronique est ouverte au degré d'ouverture maximal, commander le climatiseur pour qu'il fonctionne pendant une durée prédéfinie, de façon à régler une différence de pression entrée-sortie d'un clapet de non-retour. La vanne de détente électronique est commandée pour être ouverte au degré d'ouverture maximal, de façon à augmenter la vitesse de circulation d'un fluide frigorigène, et lorsque la vanne de détente électronique est ouverte au degré d'ouverture maximal, le climatiseur est commandé pour qu'il fonctionne pendant une durée prédéfinie, de telle sorte que la différence de pression entrée-sortie du clapet de non-retour répond aux exigences d'ouverture et de fermeture du clapet de non-retour, ce qui permet de réduire la probabilité de défaillances d'ouverture et de fermeture du clapet de non-retour. La présente demande divulgue en outre un dispositif de commande d'un climatiseur, un climatiseur et un support de stockage.
