[EnergyPlus_Support] about the different fan model

["beyangj" <beyangj@xxxxxxxxxxx>]

I built a model with air-cooled chiller, and the fan model is the 
Fan:Simple:Variable Volume, and the fan coefficient values were set 
as the values of Inlet Vane Dampers in table 20 on page 748 in the 
InputOutReference. The model was run and the electricity consumption 
of the fan and the chiller was got. Then the Fan:Simple:Variable 
Volume was substituted by the Fan:Simple:Const Volume and the model 
was run again, and also the electricity consumption of the fan and 
the chiller was got. I found that results of these two cases were 
almost the same, even the result of the model with constant air 
volume fan was a little smaller thant that of the other model.  In 
theory, the model with variable air volume fan will consume less 
energy than the model with constan air volume fan. I wondered why 
that happened. Thanks in advance!

Best, 

Stewart
