PROBLEM TO BE SOLVED: To attempt adequacy of an operation number of compressors and electric power saving.SOLUTION: A compressed air feed system supplying compressed air with multiple compressors to compressed air piping laid in a plant comprises: air supply amount measurement means for measuring actual air supply amount of each compressors to the compressed air piping; suction thermometry means for measuring actual temperature of the air sucked by each compressors; air supply capacity calibration means for correcting air supply capacity of each compressors based on the measured actual temperature of the air sucked by each compressors; and air supply margin output means for calculating and outputting air supply margin from a difference between a total amount of the corrected air supply capacity of the multiple compressors and a total amount of the measured actual air supply amount. |
