Abstract
Regarding rooms other than a room being targeted, a controller controls the rooms in energy-saving conditioning mode when a person is not detected in the rooms, even when the rooms are scheduled to be controlled in ordinary conditioning mode in a temperature control schedule. At this time, when the controller judges that the person has exited the room, the controller controls the targeted room in energy-saving conditioning mode, in rapid conditioning mode. As a result, the room is rapidly conditioned such that the temperature changes from an energy-saving temperature t to an ordinary set temperature by the time the person who has exited the room enters the room. As a result, unnecessary conditioning of the room set to be conditioning in ordinary conditioning mode can be reduced, and energy consumption can be reduced. In addition, comfort of the person entering the room can be ensured by prediction of the movement of the person.
