L'invention concerne un système de climatisation qui comprend : une pluralité de climatiseurs qui climatisent des zones climatisée respectives d'un espace climatisé ; des capteurs de détection de personne qui sont disposés respectivement au niveau de la pluralité de climatiseurs ; et un dispositif de gestion qui gère la pluralité de climatiseurs. Chaque climatiseur parmi la pluralité de climatiseurs peut ajuster le volume de soufflage d'air de climatisation qui est soufflé dans différentes directions de soufflage. Lorsqu'une personne est présente dans une zone dans laquelle la capacité est insuffisante, le dispositif de gestion utilise des informations de disposition et la température mesurée par un capteur de température du climatiseur qui a une capacité insuffisante : pour sélectionner au moins un climatiseur qui doit être amené à effectuer des opérations d'assistance ; et pour trouver un volume de réglage pour le volume de soufflage. Ensuite, le dispositif de gestion augmente le volume de soufflage du climatiseur sélectionné(s) dans une direction d'assistance vers le volume de réglage.
