Abstract

L'objectif de la présente invention est d'améliorer l'efficacité de fonctionnement d'un appareil de climatisation comprenant une pluralité d'unités intérieures et une unité d'extérieur qui partage un système réfrigérant avec les unités intérieures, en fonctionnant sur la base d'un mode de fonctionnement approprié. La présente invention concerne un appareil de climatisation comprenant : une pluralité d'unités intérieures (20a à 20e) ; une unité extérieure (30) qui partage un système réfrigérant avec la pluralité d'unités intérieures (20a à 20e) ; et une unité de commande. Lorsqu'une demande de fonctionnement est envoyée par une unité intérieure qui a été réglée comme unité intérieure prioritaire parmi la pluralité d'unités intérieures (20a à 20e), l'unité de commande détermine, comme mode de fonctionnement à exécuter, un mode de fonctionnement qui correspond à l'unité intérieure prioritaire. Lorsqu'aucune demande de fonctionnement n'est envoyée par l'unité intérieure prioritaire, ou lorsqu'un délai prédéterminé s'est écoulé depuis qu'un mode de fonctionnement correspondant à une unité intérieure autre que l'unité intérieure prioritaire a été déterminé comme mode de fonctionnement à exécuter, dans des conditions où il n'y a pas de demande de fonctionnement envoyée par l'unité intérieure prioritaire, l'unité de commande exécute un processus de redétermination au cours duquel le mode de fonctionnement à exécuter est redéterminé, et le mode de fonctionnement à exécuter est déterminé en fonction des résultats de la redétermination.
