SharePerformance of variable speed centrifugal chillers.
Author(s) : MULUGETA J., DIETRICH W.
Summary
Most centrifugal chillers are designed to operate at fixed speed, with load control provided by compressor inlet guide vanes and/or hot gas bypass. The cooling water temperature available for a centrifugal chiller will vary with the seasons, the time of day, and changes in the weather. The paper describes the performance improvements that follow from reducing compressor speed in relation to cooling water temperature and chiller load. The interaction of speed control and inlet guide vane control is discussed. Both single stage and multistage compressor applications of variable speed drive are considered.
