PURPOSE: An operating method of an air-compressor system for saving energy and a subsidiary equipment are provided to effectively control the number of operating air compressors while driving an air compression utility system. CONSTITUTION: An air compressor system comprises the following steps. An air compressor system is composed of air compressors(120,130,140) which are connected in parallel. The instant flow rate of each air compressors is stored in database. The number of operating air compressors in real time is compared with the required number of operating air compressor in real time based on the instant flow rate which is stored in the database. A comparison result according to the required number of operating air compressors in real time is presented. The air compressor which includes an automatic control circuit which independently controls driving condition automatically controls the driving capability according to the output flow rate or the pressure of the compressed air.
