Has anyone modeled SCUs (self contained water cooled AC units) in OpenStudio or EnergyPlus?
They are basically a VAV air handler that has a large water cooled heat pump in it in place of coils. The heat pump is connected to a condenser loop, and then also there is a separate water side economizer in the unit. Downstream of the AHU are VAV boxes with reheat. An example unit is the Trane PKG-DS-6.
I can't figure out how to model this because E+ won't allow water to air heat pump coils on an air loop. Has anyone modeled one of these in the past? If not, does anyone have any idea how to? I will be modeling it in OS, but if someone knows how to do it in E+ I can write a script to do it in OS most likely.
Thanks
