Air-conditioning ventilation system

An air-conditioning ventilation system comprising:

• at least one ventilation device configured to circulate air among a plurality of rooms;
• at least one air-conditioning apparatus provided in at least one of the plurality of rooms;
• a human detector provided in each of the plurality of rooms and configured to detect at least one of a height and a body temperature identifying an individual entity of a human present in a corresponding one of the rooms in which the human detector is provided;
• a temperature detector provided to each of the plurality of rooms and configured to detect a temperature in a corresponding one of the rooms in which the temperature detector is provided;
• an input unit configured to receive input of air-conditioning preference information including at least a setting temperature for each of the plurality of rooms, together with information identifying an individual entity of humans;
• and
• a controller configured to
• receive information obtained through detection by the human detector as individual behavior pattern information identifying the individual entity of the human present in each of the plurality of rooms, and store the individual behavior pattern information for each of the plurality of rooms,
• estimate presence or absence of any human in each of the plurality of rooms, or a human presence ratio representing a number of humans present per unit time in each of the plurality of rooms, on a basis of a past result of detection by the human detector, and determine a target temperature for each of the plurality of rooms on a basis of individual preference information of the identified individual entity indicated by the individual behavior pattern information for each of the plurality of rooms, and
• control the ventilation device and the air-conditioning apparatus on a basis of the estimated presence or absence of the human in the room, or the estimated human presence ratio, and the determined target temperature, wherein
• the controller is configured to control the ventilation device and the air-conditioning apparatus, on a basis of a temperature difference between the temperature detected by the temperature detector and the target temperature set for each of the plurality of rooms and the result of the estimation by the controller, to bring the temperature in the corresponding one of the rooms close to the target temperature, and wherein
• if a third room, which is one of the plurality of rooms with an estimated value of the human presence ratio after lapse of a first time equaling or below a second threshold, has an air conditioning load smaller than an air conditioning load of a fourth room, which is another one of the plurality of rooms communicating with the third room via the ventilation device, and if the presence of any human in the fourth room within a second lapse time is estimated, the controller is configured to operate the ventilation device to let air in the third room flow into the fourth room.

• if two of the plurality of rooms each with an estimated value of the human presence ratio after lapse of a first time equaling or exceeding a first threshold communicate with each other via the ventilation device, the controller is configured to operate the ventilation device to let air in one of the two rooms with a smaller air conditioning load flow into another one of the two rooms.
