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
