[Equest-users] ERV used as make-up air

[Victor Yeung]

Hello all,

 

Is there anyone who can give me some pointers on how to model this?
Basically, I am trying to model a standalone store, with the retail area
being served by three unitary RTU's.  I have divided the retail area
into three thermal zones (for each RTU).  However, a separate ERV is
supplying OA to the entire retail area @ 900cfm continuously during
store hours.  The RTUs has CO2 sensors such that it will bring in
additional fresh air if demand is greater than the ERV supply.  How
should I model this?

 

Regards,
