Hello all,
I'm getting a few warnings (which I would like to get rid of) in my simulation when it comes to the user defined sizing on my VAV w/reheat and the design. Here is the error I am getting for a few of my VAV boxes:
*** SizeHVACSingleDuct: Potential issue with equipment sizing for AirTerminal:SingleDuct:VAV:Reheat = "AIR TERMINAL SINGLE DUCT VAV REHEAT 70". * ~~~ * User-Specified Maximum Flow Fraction during Reheat of 0.50000 [] * ~~~ * differs from Design Size Maximum Flow Fraction during Reheat of 1.00000 [] * ~~~ * This may, or may not, indicate mismatched component sizes. * ~~~ * Verify that the value entered is intended and is consistent with other components.
I believe this is a problem with the hard set values I put in for my VAV w/reheat box and design heating airflow for the thermal zone. I have tried many different approaches including setting design air flow fraction to 0, but the error continues to persist. I'm still unsure which input is directly causing this error because I don't see anything specifically saying "Design Size Maximum Flow Fraction during Reheat" that I can set.
The two image below are my VAV w/reheat user inputted values and the thermal zones design heating parameters.
