Daikin moves to stepless control of screw chillers

chiller
Screw compressors with stepless capacity control are now being used on Daikin’s entire range of chillers.
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.
