[Equest-users] Supply fan kw calculation

[Shubhankar Bhagwat]

Hello
Thanks Soham for the information. I was going through the DOE-2 engineers manual version 2.1A. I read though the algothrithm of subroutine FANPWR which gives the method for calculating the fan energy consumption for the supply and return fans.There they have mentioned about using correction function CVAL( FAN-EIR-FPLR, PLsupply) for FAN-CONTROL=FAN-EIR-FPLR in order to calculate the suppy and return fan energy consumption. Does anyone have any idea about the method for calculating that function. Any insights would be of tremendous help.
Thank you

Hello,

Can please anyone guide me on the calculation of Supply fan Kw in an AHU system with regards to the mathematical computation which goes behind it. I am using FAN CONTROL = FAN-EIR-FPLR strategy. I wanted to mathematically compute SFKW which is the Supply fan KW usage by using basic parameters like Supply-Delta-T( i.e the temperature rise in the air stream across the supply air fan), supply-CFM (i.e. design,rated capacity of supply air fan).  A basic idea of the formulation would help a lot. Do tell me if I should be giving some more specific details.

Thanks in advance
