Title: Air conditioner control system and control method thereof

Abstract: An air conditioner control system comprises an outdoor unit having acompressor controlled by pulse-width modulation, and a plurality of indoorunits. Each of the plurality indoor units has an indoor control unit tocalculate a respective required individual cooling capacity, and an indoorcommunication circuit unit through which the required individual coolingcapacity calculated is transmitted. The outdoor unit has an outdoorcontrol unit producing a duty cycle control signal in response to therequired individual cooling capacity transmitted from the indoor units tocontrol the capacity of the compressor, and an outdoor communicationcircuit unit to communicate the indoor communication circuit unit ofrespective ones of the plurality of indoor units. Each of the plurality ofindoor units calculates the required individual cooling capacity based onat least one of an available cooling capacity of the respective one of theplurality of indoor units itself and the difference between a detectedindoor air temperature and a preset temperature.
