Air conditioner's central controlling system and its operating method

The present invention is connected via a plurality of air conditioning and network network installed in each room function control of each air conditioner, as well as converts the operation mode of the respective air conditioners such that the total peak power of the air conditioner that is the actuator limited to within input the set power level control It relates to a central control system of the air conditioner, connected through, which is installed a plurality of air-conditioned, of the multiple air conditioning and network mans for each room in the building for the air conditioner is input a control command for the monitoring and control of each air-conditioning , in accordance with the configured, including a central controller for controlling the total operation of the respective air conditioners to be limited to a total peak power consumption during the operation of the one of the plurality air conditioning within the set power value in accordance with the autonomous algorithm set, while maintaining the minimum air-conditioning effect the power used to prevent a total peak power value exceeds a set power value Minimize the cost burden and has the advantage that it can reduce the risk of power supply is cut off to the entire building.
