The purpose of the present invention is to provide an air-conditioning system (100) which performs long-term demand control. The air-conditioning system (100) is equipped with one or more air conditioners, one or more centralized control devices, and transmission lines that connect the air conditioners and the centralized control devices. The centralized control devices (1A, 1B) define the amount of energy usage that a user is to achieve in an arbitrary period, set the amount of energy usage as a target value for the demand control, obtain the running information of the air conditioners (2A to 2E, 3A to 3J) up to the present time through the transmission lines (13A to 13E, 14A to 14J), store the running information, and calculate a running plan for limiting the amount of energy usage within the target value of the demand control on the basis of the running information. |
