Hi everyone, I don't know whether or not this question is fit for this forum. I'm doing a project for a class I'm taking at the Univ of Illinois, and I know very little about HVAC.
I am wondering how I can convert a CFM figure to energy use. For instance, if my AHU was doing 35,000 cfm and I know some of the basics regarding the fan (HP, volts, Hz, 3 phase, etc). Is there any form of general equation to get from cfm to energy input to run the fan? Also, would the equation be different if a VFD is being used rather than a traditional drive?
Thanks for any help you can provide!
