[Equest-users] Air side HVAC

[John Aulbach]

Sambhav:

If you want Exhaust CFM Fan energy, then I believe you need to specify Exhaust CFM.

OK, eQuesters, I think I have this straight. If you specify an Exhaust CFM LESS THAN OSA CFM, nothing airwise changes, and Exhaust CFM translates to an Exhaust fan HP. If Exaust CFM EXCEEDS OSA CFM, the OSA CFM is increased to account for no negative airflow. And Exhaust CFM STILL creates and Exhaust HP.

Comments from our studio audience, please..

Hi  All,
              In the AIR side HVAC under zone when we go to outdoor air tab there it asks about exhaust fan cfm for each zone so do we have to specify it exhaust cfm zonewise or the program assumes it that what ever is the fresh air cfm for each conditioned zone same will be the exhaust cfm.

Any response will be appreciable.

Thanks
Sambhav Tiwari.
