[EnergyPlus_Support] Enquiry

["eric_zhou1223" <eric_zhou1223@xxxxxxxxx>]

Hi£¬

I am simulating an all-air system,in which actually there are multiple 
AHUs serving different zones, then here come my questions--- the first 
one: do I need to use several AHUs to meet loads as in real life, or, 
simply to use a single "conceptual" AHU to satisfy  the whole building? 

The second one , what is the difference between "Des Air Flow Rate" 
and "User Des Air Flow Rate"? I used autosizing everwhere, without 
defining the flow rate at all.

The last qustion is in which condition I would have to change the "zone 
sizing fator" from the default 1 to whatever. I read the document and 
was not sure of the implications.

Thank you 
Eric YP Zhou
