Daikin moves to stepless control of screw chillers
Published: July 2005
Daikin is upgrading its entire range of screw chillers to use compressors with stepless control. The G type single-screw compressor provides infinitely variable capacity control from 30 to 100% on single-circuit units and from 15 to 100% on dual-circuit units by modulating the position of the sliding valve according to the chilled-water control condition. The main benefits of continuous modulation are improved part-load efficiency and more stable chilled-water temperatures with closer control tolerance. Related articles:
