Claim:
A storage type air conditioning system having a plurality of storage type air conditioners, wherein each of the plurality of storage type air conditioners comprises: a storage battery in which external power from an external power source can be stored; an air conditioning unit that is supplied with stored power from the storage battery and performs an air conditioning operation; a residual amount detector for detecting a storage residual amount of the storage battery; a stored power transmission and reception switching unit for switching transmission and reception of the stored power stored in the storage battery to and from the other storage type air conditioners; a storage controller that transmits and receives information concerning the storage residual amount of the storage battery to and from one of the plurality of storage type air conditioners, and controls the stored power transmission and reception switching unit so as to supply stored power of the storage battery to another of the plurality of storage type air conditioner in which the storage residual amount is short with respect to the stored power supply amount when the storage residual amount of the storage battery is surplus with respect to a stored power supply amount to be supplied to the air conditioning unit, and also receive stored power from another of the plurality of storage type air conditioner in which the storage residual amount is surplus with respect to the stored power supply amount when the storage residual amount of the storage battery is short with respect to a stored power supply amount to be supplied to the air conditioning unit; wherein the storage controller is connected to an information transmitting and receiving signal line connected to the plurality of storage type air conditioners, and transmits information concerning the storage residual amount of the storage battery of said one of the plurality of storage type air conditioners and receives information concerning the storage residual amount of the storage battery of each of the other of the plurality of storage type air conditioners; and a surplus stored power transmitting or receiving line for transmitting or receiving surplus stored power to or from another of the plurality of storage type air conditioners on the basis of the information concerning the storage residual amount of the storage battery.
