It's more generally an E+ question, but I am using OpenStudio (worth noting because I know there are some "issues" with where to place setpoints on inner nodes (read here))
I want to model a rooftop unit with water-cooled DX units (no heating, no reheat). I'm therefore planning to use an AirLoopHVAC:UnitarySystem with a Coil:Cooling:WaterToAirHeatPump:EquationFit. I also want to use a Fan:VariableSpeed.
My understanding is that I can put my fan either inside the unitary system, or I can put it on the AirLoopHVAC supply side by itself. First, is that correct?
Second, if correct, which way should I use? Is there any advantage/disadvantage of putting it inside versus outside?
