Trane, La Crosse, Wis., now offers a complete line of refrigerant-cooled, unit-mounted adaptive frequency drives (AFDs) for its CenTraVac centrifugal water chillers. AFDs control the voltage and speed of a chiller compressor based on a building's cooling needs, saving energy when the chiller operates at part-load or in off-design conditions. The feed-forward adaptive control system foresees load changes and quickly adapts to the chiller's operating ranges and its specific characteristics before the leaving temperature of the chiller is affected. The result is better efficiency and stability at reduced or variable flow.
