[Equest-users] eQuest Users Group - Setting outside air minimum

I could be wrong, but I believe that specified zone OA rates/ratios
takes precedence over the system specification.  Check the OA for each
zone, and see if there's anything there.

 

If that's not it, I don't have any other ideas.

 

Hope this helps.

Hello folks,

 

Hopefully someone knows how to deal with outside air.  I can't seem to
figure out how to set my minimum outside air on my HVAC systems.  When I
set my OA minimum on my Air system , and adjust the minimum OA fraction
in my schedule I still get ventilation results below my set minimum.  It
seems, no matter what I do to the outside air setting on the system side
the program sizes the OA ventilation based solely on what my outside air
ventilation rates of the individual spaces and ignores any setting I put
in my system.  Does anyone have experience on how to remedy this?

 

 

 

 

 

 

 

-          Thank you,
