<P>PROBLEM TO BE SOLVED: To accurately charge each indoor unit user using electric power for the electric power when there are both a group of regenerative air conditioners and a group of those without heat storage tanks. <P>SOLUTION: The system comprises a power meter 4 for measuring the total used electric energy and an interface 6 for transmitting data indicating the electric currents by each operation mode and outdoor unit 1, and the operation time, the time when a thermostat is on, and the refrigerant flow by each indoor unit 2 from a signal line 1 connected to an outdoor unit 1 and an indoor unit 2 to an electric power management unit 7. The value of the storage electric energy is apportioned among outdoor units 1 at the ratio of the operation current integration value calculated from the electric current data by each outdoor unit 1, and the apportioned value is further apportioned among indoor units 2 at the rate calculated based on at least one of the operation time, the time when the thermostat is on or the refrigerant flow by each indoor unit 2 using the storage heat at the time of use for air-conditioning from after the finish of the heat storage till the start of the heat storage. <P>COPYRIGHT: (C)2004,JPO |
