[Trace-users] VAV System Modeling - Carrero

This pretty straight forward in Trace. I don't have trace in front of me but create two vav systems, one can be shut-off vav, one fan powered vav if that is how you are zoning. On the room air flow tab you can select shut-off vav for any interior room.

A vav RTU can serve both interior and perimeter. Select fan powered vav system and override the interior rooms with shut-off vav terminals from the airflows tab. This may simplify you duct routing. Refer to Trace documentation under Help.

>I am modeling a building with 2 DX VAV rooftop units with electric heat. These rooftops serve VAV terminals (on interior spaces) and series fan terminals serving the perimeter. When I try to model this simple system on TRACE, I can select either a Series Fan-Powered VAV system, in which ALL the terminals will have fans, or a Variable Volume system, in which NONE of the terminals will have fans.
>I can not model my RTU as it if was 2 RTUs, one for the interior with VAV terminals and one for the perimeter, with FTUs. This would defeat the whole purpose of having a VAV system, as the interior spaces would be most likely a constant volume.
