air to air transfer between PAU and AHU (OpenStudio)
I am using OpenStudio to model the HVAC system of a multi-story office building. The cooling requirements of the spaces on each floor are served by AHUs (for office spaces) and FCUs (for common areas). Fresh air or makeup air is provided by PAU units with air to air exchange to the AHUs and AHU to spaces with FCUs/VAVs to meet the ventilation requirements both being powered by DCS and no heating. How would I model this in openstudio?
Edit: I came up with something by scouring UMH and I came up with this.
Plant DCS with VAR SPD PUMP --> 2 CHW Coil ==> PAU and AHU Airside PAU(100% OA Yes) OAS --> CHW Coil--> Diffuser ==> Zones(DOAS on) AHU(100% OA No) OAS(0m^3/s) --> CHW Coil--> Diffuser ==> Zones(DOAS on)
Will this be the same as
DCS --> CHW Coil --> PAU(Precooled) --> AHU --> VAV(FCU)
Any Help is Welcomed!
Much Appreciated!
