| 20110231019 | CENTRAL AIR-CONDITIONING SYSTEM - A central air-conditioning system conditions a house having a plurality of rooms. When a person is not present in any of the rooms, each room is conditioned in energy-saving conditioning mode having a low load. On the other hand, when the person is detected in any of the rooms, a controller switches an operating mode for conditioning the room, in which the person is detected, from the energy-saving conditioning to rapid conditioning. Air-conditioner ducts respectively connected to the remaining rooms are closed. Therefore, cold air or warm air from an air-conditioning unit is supplied to the room in which the person is detected, while the cold air or warm air is not supplied to the rooms in which the person is not present. As a result, the room that has been switched from energy-saving conditioning to rapid conditioning is conditioned in a concentrated manner. | 09-22-2011 |
| 20110130881 | CENTRAL AIR-CONDITIONING SYSTEM - 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. | 06-02-2011 |
