How to model DOAS w/ DCV in Openstudio?
I am modeling a building that uses DOAS w/ DCV and active chilled beams. The ACB is constant volume and DOAS is variable volume, so I model ACB using FCUs. Now the question is how can I implement DCV in DOAS? I turn the DCV on in the control and the outdoor air seems correct. But the DOAS supply air is not 100% OA. Where can I set the DOAS to be 100% OA while the OA cfm might vary?
