[EnergyPlus_Support] Re: enquires (URGANT)

I think one mixing box can only be connected in one system. Maybe u 
can establish 2 different single systems by adjusting the air flow 
rate - one for all outside air (100%)and one for the room air (with 
0% of outside air).

outlet loop of zone oulet but use the spliter as for spliting the 
return air back into return air node.

help to solve the problem. I am urgant to establish this system. Look
