[EnergyPlus_Support] Minimum "Fixed" Outside Air

["aboyemeplus" <Merid.Aboye@xxxxxxxxxxxxxx>]

Hi,

I am having difficulties understanding why the System Sizing routine 
limits the calculated system design air flow rate to a value lower 
than the user-input "Fixed" mimimum outside air flow rate, when the 
zone temperature is below the heating setpoint temperature. 
Lowering the supply heating air temperature resulted in even lower 
zone temperature without any changes to the calculated design flow 
rate. In a sizing calculation, I would expect a higher flow rate to 
be calculated to meet the setpoint temperature. Apparently i must be 
missing something! Please provide insight when possible. If you need 
a file to work with, use the IDF uploaded in the 
PROBLEM_SUBMITTAL\MAB3 folder on 10/10. Thank you for your support.

Merid 

P.S.
Calculated heating design air flow rates reported in the ".eio" file 
(under the System Sizing Information section)  are different that 
values listed in the ".CSV" file. Am I reading the reports wrong? 
Please verify if you have some time.
