Dear All,

I am trying to model a system with 1500 CFM system supply but no return,
all of the flow will be exhausted from the zones. Looking at hourly
reports, I can never get the return flow to be zero, eQuest will always
add exhaust and return and make my system supply 3000 CFM. How does one
zero the return flow?

Thanks,

Omer Moltay

You need to exhaust the 1500 CFM. If you exhaust 1200 eQuest will
assume there is 300 CFM of return air. Your model is a box.
_Everything_ going in or out must balance. If you don't do it eQuest will.
