[Equest-users] Problem with Exhaust fan simulation

[Byron Burns]

Have you tried distributing the exhaust to zones close to the kitchen,
which may provide make up air to the negatively pressurized space?
Either that or create a smaller subzone that you can change the balance
of exhaust air source to infiltration rather than from air handler.

Subject: [Equest-users] Problem with Exhaust fan simulation

 

Hello all,

The project that I'm working at has Exhaust fans for service areas and
kitchens. I entered EFs data within the Wizard Screen 14 (Zone Group
Definitions, Zone Group Details). For the baseline model which s in
Auto-sixe Flow condition for Supply Fans there is no problem and eQUEST
simulate the project. But for Design model that I entered the Fan Flow
and OSA from drawings, the simulation terminates due to the following
error:

 

 

 

Although I increased the assigned the same air flow or larger volume
than the exhaust flow (in DDE mode), the error remains the same.

 

Your help would be greatly appreciated.
