The technical feasibility and cost effectiveness of using advanced compressor control techniques to provide improved energy and use efficiencies and peak demand reductions in large commercial and industrial compressor systems were investigated. The control techniques addressed included the timely modulation of compressor suction, interstage and discharge pressures (for cooling and refrigeration systems) and discharge pressures (for air and gas compression systems) to match daily and seasonal variations in application requirements. Other compressor optimization techniques investigated included the use of simple turnoff of unneeded compressor capacity and selection of the most efficient compressor(s) to match instantaneous loads. Results indicated that large energy savings (typically 10 to 40%) and similar peak demand reductions could be achieved with fairly low implementation costs in a wide range of commercial and industrial compressor systems. Simple payback periods for these applications were frequently less than two years and operational impacts were minimal. Project assessments of compressor energy use patterns indicated that large (over 30 horsepower) compressors consume over 140 x 10/sup 9/ KWH/year in the US and widespread use of the project-developed compressor control techniques would provide significant utility industry peak demand reductions and electrical energy and use efficiency improvements.
