Abstract: 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.

In the central control system, multi-type air conditioners comprise a large number of indoor devices and a small number of outdoor devices, and a central controller is coupled to the multi-type air conditioners over a network. The central controller transmits a control graphic user interface (GUI) program provided therein to the remote control device so that an integrated control operation for respective air conditioners can be carried out. The central controller adjusts a transmission time of the control command signal received from the remote control device and transmits the control command signal to a corresponding air conditioner according to a result of the adjustment so that signal collision can be avoided.

It is thus possible to determine respective power consumption patterns and electricity charges of the indoor units more accurately, thereby improving management efficiency of the entire air conditioning system.

Abstract: A central control system includes a plurality of air conditioners and a central control unit connected to the air conditioners over a network. The air conditioners are installed in rooms of a building to provide air conditioning in the rooms. The central control unit receives a control command for monitoring and controlling each of the air conditioners, and adjusts an operating schedule of each of the air conditioners to limit total peak power consumption of the air conditioners in operation below a reference power value. The central control unit controls the operation of each of the air conditioners based on the adjusted operating schedule. When the total peak power consumption exceeds the reference power value, the central control unit prevents the entire air conditioning system from shutting down, which improves stability of the air conditioning system and decreases electricity costs for air conditioning.
