[EnergyPlus_Support] Re: Variable Speed Fan

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear Elreq,
I recommend that you review the Input Output Reference, starting at
page  1162.  Several fans are discussed.  In short:
Fan:Simple:Const Volume is a constant volume, continuous operation fan
which can be turned on and off via a schedule.
Fan:Simple:OnOff is similar to the one above, but it cycles itself on
and off as required by its thermostat ... all during the scheduled
operation period.  This is a typical mode of operation for a home furnace.
Fan:Simple:Variable Volume runs continuously during the Schedule
period, but varies its volume to meet the heating or cooling demand.

I hope that this is helpful!
