[EnergyPlus_Support] Re: Setpoint Managers are driving me crazy!



Dear James,
if I understand right, you want to dehumidify with the coil adjacent to the heat exchanger. So I'm a little puzzeled why this coil has a setpoint manager with control variable type "temperature". I would have thought that this is exactly where the humidity setpoint would be assigned. 

If you where assigning a temperature setpoint here in a way that accounts for any heat additions downstream into the air stream by things like the fan (actually I think only the fan heat is supported at the moment). To do this, you would assign it with a "MixedAir" setpoint manager so that you get at the very last outlet node (where you assign the wished for outlet temp setpoint with a normal manager which the MixedAir manager references).

I would have thought that the analogy exists for the humidity, as in a MixedAirHumidityManager that you would use to assign the humidity setpoint at the exit of your humidity controling coil, and that this manager would referance the wished for humidity at outlet setpoint, which would hopefully mean that humidity additions from downstream equipment like the ODA mixing box would be appropriatly taken into account.

Does this analogy not exist?!
