Abstract

L'invention concerne un système de gestion de conditionnement d'air permettant de réguler le climat dans un espace régulé tel qu'une chambre, un appartement, ou un autre espace enfermé ayant une ouverture pouvant être fermée telle qu'une porte ou une fenêtre, et un capteur pour détecter si l'ouverture est ouverte ou fermée. L'espace régulé comporte une unité de demande en énergie de conditionnement d'air telle qu'un thermostat, qui est couplée à un générateur de conditionnement d'air tel qu'un élément chauffant, un climatiseur, et analogues. Le système est construit de façon à fournir une demande en énergie plus faible si l'ouverture est ouverte. Ainsi, par exemple, dans un système chauffant, le système répondra à l'ouverture de la fenêtre par la réduction de la température effective souhaitée définie par l'utilisateur. Un aspect facultatif de l'invention permet en outre l'enregistrement d'informations concernant la consommation en énergie de l'espace régulé.
