STORAGE TYPE AIR CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To provide a storage type air conditioning system capable of efficiently equalizing electric power demand. SOLUTION: The storage type air conditioning system has air conditioners 2A, 2B and a storage battery 33 for storing commercial electric power of a commercial power source 10, and supplies stored electric power and the commercial electric power, stored in the storage battery 33, to operate the air conditioners 2A, 2B. The storage type air conditioning system comprises a storage air-conditioning controller 33 carrying out charge to the storage battery 33 at night when electric power demand is less, and discharging stored electric power charged in the storage battery 33, in a discharge period T2 including at least a peak period T3 of electric power demand. The storage air-conditioning controller 33 is constituted to control the discharge of the stored electric power so that the residual electric power amount Wz of the stored electric power is almost zero at the end of the discharge period T2.
