ENERGY SAVING OPERATION DIAGNOSIS FOR MOTOR-DRIVEN AIR COMPRESSOR AND ENERGY SAVING OPERATION DIAGNOSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To clarify the energy saving operation of a compressed air supply system in an arbitrary time zone by making comparative evaluation between the power consumption cost of respective air compressors based on measuring data and the power consumption cost assumed under a particular energy saving operation condition. ;SOLUTION: When a sensor part 11 detects suction pressure Ps or discharge pressure Pd at least at the time of operating respective air compressors 2..., a data storage part 12 converts detected measuring data and stores them at fixed time intervals. A current running state storage part 13 obtains the load factor, power consumption cost and the whole discharged air quantity of the respective air compressors at fixed time intervals based on the stored measuring data. An energy saving operation state computing part 14 obtains power consumption cost under an operating condition assumed in advance where the same air quantity as the whole discharged air quantity of the compressors obtained from the measuring data is generated by the energy saving operation of the respective compressors 2 as near to 100% load factor as possible. The data obtained by the computing parts 13, 14 are comparatively-evaluated on power consumption cost in the same time zone by a display part 15.;COPYRIGHT: (C)1997,JPO
