<P>PROBLEM TO BE SOLVED: To provide an air conditioning system and a control method therefor which securely acquire operation data, do not lack data used for calculating proportionally divided charge data, and after having calculated proportionally divided charge data once, can calculate proportionally divided charge data again. <P>SOLUTION: The air conditioning system has an outdoor unit and a plurality of indoor units, carries out central control by a central control device, and calculates a usage charge corresponding to an amount of use of each indoor unit, as proportionally divided charge data. The central control device acquires operation data on the basis of an operation status of each indoor unit at every given time, and stores the acquired operation data in a database in order. Upon calculating the proportionally divided charge data, the central control device extracts the operation data used for calculating the proportionally divided charge data from the database and calculates the proportionally divided charge data on the basis of extracted operation data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
