This study examined the potential for energy savings which exists when a factory is operated from multiple frequency electric power. In a previous study it was demonstrated that power hand tools operating from 360 to 400 Hz electric power achieve significant energy savings compared to the currently popular compressed air power tools. Fluorescent lighting and high intensity discharge lighting also are known to be more energy efficient when operated from electric power at frequencies higher than 60 Hz. Because the energy input to lighting and tooling is almost entirely converted to heat in the factory, energy conserved through more efficient tooling and lighting will also influence the heating and air conditioning requirements of the factory. The current study has developed quantitative data and methods which permit an engineering assessment of the energy savings potential from multiple frequencies in any specific factory are provided. Incremental energy savings estimates were developed which can be applied to any factory on the basis of the number of square feet in the factory. Areas within the factory at different light levels or with different amounts of tooling can be treated independently. This study was divided into six tasks as follows: energy savings from high frequency tooling; energy savings from high frequency lighting; multifrequency generator/conversion configurations; methods for including multifrequency savings in co-generation systems; relative cost requirements; and a field investigation of recent co-generation installations to determine the compatibility of such systems with multifrequency operations. It is concluded that there are appreciable savings in energy to be realized through multifrequency operations and the data and methods required to compute these savings in any specific factory are provided.
