[EnergyPlus_Support] Re: Error message on flow rate

Hi, Linda,

Thanks for your response. I have a question regarding the air loop 
you mentioned. 

I have a supply fan and a return fan in the system. What I did is to 
put the supply fan in one branch (main air loop branch), and the 
return fan in another (return air branch). The primary air loop 
consists of these two branches. I think the outlet from the return 
air branch is the return air inlet for the outside air system of the 
main air loop branch. If this is not the correct way to do it, could 
you please let me know what I should do?

Thanks again,
