Application Note: APPLYING INVERTERS TO CENTRIFUGAL COMPRESSORS IN HVAC CHILLERS Please refer also to the Inverter Instruction Manual AN060404-1 Hitachi America, Ltd. © 2004 Hitachi America, Ltd.
These are constant torque loads, and do not offer significant energy savings potential. Screw-type compressors present other technical problems, and are probably not suitable for use with inverters. Again, consult the chiller manufacturer for specific recommendations. Hitachi America, Ltd. © 2004 Hitachi America, Ltd.
