I am trying to build a calculation that would allow the users to enter the vintage of the existing chiller and then estimate energy savings by going with a new efficient chiller so I don't have the luxury of delta T or amp readings. It is a real rough calc and I am having problems finding...
In Response to jbartos:
The motor drives a fan for a cement kiln. It's loading varies from 30% to 100%. The AC motor controller is a standard PWM VFD. No potential for regeneration.
I am working on a project where they replaced a 3000hp DC motor with a 3000hp AC motor. They are claiming significant energy savings by going with an AC motor with VFD control. The old DC motor also had speed control. The 2 motors have very similar efficiences (95.4%-DC, 96%-AC).
Is there...
I am trying to work up a "quick and dirty" energy savings calculation that is based on industry average kW/Ton for older chillers and the vintage (year).
I know I have seen a list of typical kW/Ton for older air-cooled and water-cooled chillers but I can't seem to find it. Any ideas...
