A central control system for airconditioner(s) and a method for controlling the same. The central control system can centrally control a plurality of airconditioners connected to the same communication network. In the system, a protocol converter connected to a central controller converts a communication standard of a signal communicated between the airconditioners and the central controller into another communication standard, acquires connection state information by scanning connection state information of individual airconditioners, and transmits the acquired information to the central controller, such that a manager can correctly monitor an airconditioner state using the central controller, resulting in the implementation of a reliable control system.
