I am using EnergyPlus to model a building. I included Zone exhaust fans in the model. But,
when I auto-size the model with this Zone Exhaust Fan object, I get a
warning message saying -
** ~~~ ** there is unbalanced exhaust air flow. ** ~~~
** Unless there is balancing infiltration / ventilation air flow,
this will result in ** ~~~ ** load due to induced outdoor air
being neglected in the simulation.
And, I think the design loads are increased due to this, which would
probably cause over-sizing.
Any help in solving this issue
would be greatly appreciated.
