Does OpenStudio support Field: Design Return Air Flow Fraction of Supply Air Flow?

I have a system with less return flow than supply, so I want the autosize to size the return fan properly.

I do not see it listed in the SDK documentation, so it must not be supported.

This is supported in OpenStudio v3.1 (implemented here, courtesy of @Julien Marrec, which is now officially released.

New methods on the AirLoopHVAC object:

  • designReturnAirFlowFractionofSupplyAirFlow
  • setDesignReturnAirFlowFractionofSupplyAirFlow

You mean courtesy of me. I filed this request on GitHub. https://github.com/NREL/OpenStudio/is...

No offense, but Julien made 22 code commits across several days to implement this. I’d say it’s courtesy of his efforts.
