Air-conditioning system and method for controlling same

A control unit for a management device comprises: an air-conditioning temperature correction unit that accumulates requested temperature information for the temperatures desired by a plurality of users, compares, from the accumulated requested temperature information, the distribution of the setting temperature desired by each of the users with respect to the total number accumulated with the distribution of the number of spaces to be air-conditioned for each temperature actually provided, and if there is a difference greater than or equal to a predetermined value in the comparison result, calculates a correction value for the setting temperature for each of the spaces to be air-conditioned and corrects the setting temperature of the corresponding air conditioner; and a display unit that displays information including at least the location of each of the spaces to be air-conditioned and the temperature of each of the spaces to be air-conditioned. The control unit compares the setting temperature desired by each user with the temperature information of the space to be air-conditioned and causes the display unit to display information relating to the space to be air-conditioned having the temperature that is closest to the setting temperature desired by the user from among the plurality of spaces to be air-conditioned.
