Adding FanVariable to VAV Air Terminal Unit


I am having hard time modeling VAV with Reheat Coil that contains Variable Speed Fan(Variable Volume Fan) inside. For the EnergyPlus input class is as follows:( AirTeriminal:SingleDuct:VAV:Reheat:VariableSpeedFan)

single_room2.3dm (30 KB) (70.0 KB)


I tried several tries:

  1. merging with heating coil and inputting to AirTerminal Input.
    ->error occured

  2. tried to put Variabl Fan into Euipment input.
    ->Simulation Runs without any problem, but when opened in OS the Variable Fan Doesn’t show up…

Is there any possible way to put VariableVolumeFan into AirTerminal Unit?

Thank You!!

Hi @Jae

It seems AirTeriminal:SingleDuct:VAV:Reheat:VariableSpeedFan doesn’t exist in OpenStudio. Can you use SFP or PFP instead?

@MingboPeng Thank you for great suggestion! SFP and PFP would work fine for me.
