[Equest-users] eQuest supply cfm and OA

[Paul Erickson]

Marcus,

You need to remove any specification of OA flow at the zone level.  In eQUEST, zonal values often/always(?) trump system values.  In order to remove the value and leave the cell blank, right click and hit "restore default".

Hello,

I am working on a building comprising three main zones.  One of these zones
has a 100% OA requirement.  I would like for eQuest to auto size the supply
cfm for all zones, thus in the wizard I do not specify any flowrate or OA%.
Once in the detailed mode, under the "Outdoor Air" tab and the "Outside Air
and Economizer" screen, I set the minimum outside air ratio to 1.0.  After
running the simulation and checking the SV-A report, it says that the OA%
for this zone for the simulation was actually 3%, not the 100% this zone
requires.  Can anyone tell me how to force eQuest to 100% OA?  I looked at
the help for the outside air ratio and it stated that it was for winter
heating periods.  Is there a work around for this?  I have attached the .inp
and .pd2 files for this project.

Thank you for your assistance.
