[Equest-users] Air Change Rate Question

[Matthew Dubrovich]

Rob,

I believe you can use the Overall Design Flow (ASSIGNED-FLOW) at the zone level to set your maximum flow rate.  It's in CFM not ACH but you can let eQuest do the math for you.  In the "Edit/View User Expression" box enter: 12*#LR("SPACE","AREA")*10/60.  Where 12 is your ACH rate (use a Global Parameter to make life easier when you start changing it in the parametric run) and 10 is your floor to ceiling height.

Subject: [Equest-users] Air Change Rate Question

This should be a quick question, but with eQuest you never know.

I am trying to set my ACH rates to 12, and in an parametric run, turn it down to 6.  This doesn't appear to be working because the entry line for the ACH is minimum air to the zone.

Is there a way to set the air flow to see the ACH minimum air as a maximum?
