Hello Everyone,

I noticed that multiplier for the mid floor does not produce any effect on OA flow in DOAS with FC system. I have attached two simple models, one with FC and the other one with PTAC for comparison purpose. I have created an hourly output for supply air flow and ratio of OA to SA for DOAS system. If I change floor multiplier from 1 to 10, the outside air flow will increase for PTAC system, while the OA flow for FC will remain unchanged. What am I missing here?

Thanks

Ana
