Abstract
A central control system controls peak power of multiple air conditioners that includes indoor units installed in rooms of a building and an outdoor unit for controlling refrigerant circulation. A central controller is connected to the multiple air conditioners via a network to perform central control or monitoring of operations of the air conditioners. The central controller performs peak power control if current power consumption of the air conditioners, calculated based on operating states thereof, exceeds a previously input reference management power value. A signal converter is connected between the multiple air conditioners and the central controller to perform mutual conversion of different protocol signals communicated between the multiple air conditioners and the central controller. This decreases excessive electricity costs due to excessive power consumption while approximately maintaining cooling/heating efficiencies, and also prevents the entire power of the building from being cut off.
