Air-conditioning system and method for controlling air-conditioning apparatus

A method for controlling an air-conditioning apparatus by a controller being connected to a user-detecting unit detecting, for a plurality of users in the air-conditioning target space, an amount of activity of each of the plurality of the users and a position of each of the plurality of the users in the air-conditioning target space, and also to a storage device, the method comprising:

• storing in the storage device, for each of a plurality of amounts of activity, a group including a plurality of the comfort index distributions each being a distribution of comfort indexes each indicating a user comfort level in the air-conditioning target space, the plurality of the comfort index distributions each corresponding to each of a plurality of air-conditioning control patterns of the air-conditioning apparatus;
• specifying the group corresponding to the amount of activity detected by the user-detecting unit for each of the users;
• extracting, from the plurality of the comfort index distributions in the specified group, a plurality of the comfort indexes corresponding to a position detected by the user-detecting unit for each of the users;
• calculating a comfort efficiency indicating a comprehensive comfort level of the plurality of the users for each of the plurality of the air-conditioning control patterns based on the plurality of the comfort indexes extracted in correspondence of the detected position of each of the users;
• and
• obtaining, from the plurality of the air-conditioning control patterns, an air-conditioning control pattern that enables the calculated comfort efficiency to be maximum.
