The present invention relates to an air compressor parallel operation system and a control method of the same. According to the embodiment of the present invention, an inverter type air compressor first produces compressed air as the inverter type air compressor and a standard air compressor are operated in parallel. When the pressure of the compressed air continuously falls down to less than the loading pressure (or the pressure lower than the loading pressure by as much as the pressure defined in advance) even if the inverter type air compressor produces the compressed air to the fullest, the standard air compressor gets operated, and the production of the compressed air by the inverter type compressor is controlled while monitoring the pressure change. When the pressure of the compressed air continuously increases to greater than the unloading pressure (or the pressure higher than the unloading pressure by as much as the pressure defined in advance) even though the inverter type air compressor performs the no-load operation, the standard air compressor is stopped to use and the compressed air is produced using the inverter type air compressor. Therefore, the energy efficiency of the parallel operation can be maximized. |
