Abstract

L'invention concerne un système de climatiseur qui peut mettre à jour, à des intervalles de temps appropriés, des informations de température extérieure affichées sur un terminal mobile qui gère un climatiseur, en informations détectées par un capteur de température extérieure. Lorsqu'ils sont arrêtés, des climatiseurs (10a, 10b) placent des unités extérieures (12a, 12b) dans un état de non-alimentation en électricité mais maintiennent la fourniture d'électricité à des unités intérieures (11a, 11b). Les climatiseurs (10a, 10b) peuvent amener les unités intérieures (11a, 11b) à restaurer temporairement l'alimentation en électricité à des unités extérieures (12a, 12b) à des intervalles de temps prescrits lorsqu'ils sont arrêtés ; et obtiennent des informations de température extérieure pouvant être obtenues à partir de capteurs de température extérieure (245a, 245b). Des adaptateurs (20a, 20b) reçoivent, en tant qu'informations associées à un climatiseur, des informations de température extérieure obtenues par les unités intérieures (11a, 11b) à partir des unités extérieures (12a, 12b), et met à jour des informations de température extérieure conservées par un serveur externe (40) en informations de température extérieure obtenues par les unités intérieures (11a, 11b) à partir des unités extérieures (12a, 12b).
