Central control system for airconditioner and method for operating the same

A method for operating a central control system for use in one or more airconditioners, comprising:

• controlling a protocol converter that converts a communication protocol of a signal communicated between a plurality of airconditioners and a central controller that centrally controls the plurality of airconditioners to communicate with a plurality of airconditioners connected to a communication network according to a first communication standard, and scans network connection state information;
• acquiring connection state information from the airconditioners according to the scanned result, and updating/storing the connection state information of the acquired connection state information of the airconditioners;
• upon receiving an information request signal from the central controller, transmitting the stored connection state information to the central controller according to a second communication standard, such that the central controller automatically recognizes airconditioners currently connected to the communication network;
• displaying connection state information of the airconditioners using the central controller receiving the connection state information;
• and
• controlling the protocol converter by initializing a system of the protocol converter, calling network addresses of individual airconditioners;
• and storing the called network addresses.
