<p>PROBLEM TO BE SOLVED: To achieve electric power saving operation for suppressing excess electric power consumption. SOLUTION: An air conditioner 3k (k=1, 2, 3,...) sends operation data 51 indicative of operation conditions thereof mediating a transmission network 9. In a concentrated control center 4, an electric power saving operation program 61 is prepared for performing electric power saving operation based upon the operation data 51, which is down loaded to the air conditioner 3k. The centralized control center 4 calculates the reduced amount of electric power at need, and receives an additional profit 8 based upon the calculated result, e.g. compensation from a user 2k who uses the air conditioner 3k.</p> |
