In my multizone Energyplus model with AFN I have no gas equipment and the Carbon Dioxide Generation Rate in the people schedule in every zone is set to 0. The only CO2 sources are ZoneContaminantSourceAndSink:Carbondioxide objects.(1 in every zone)
While the output variable values from "Contaminant Source or Sink CO2 Gain Volume Flow Rate" correspond to the input schedule (right y-axis) in the "ZoneContaminantSourceAndSink:Carbondioxide" object, the "Zone Contaminant Source or Sink CO2 Gain" (left y-axis) doesn't correspond to anything. Shouldn't it be the same as the Contaminant Source or Sink CO2 Gain Volume Flow Rate? (Because there are no other sources in the zone) I
Is this expected behavior or am I missing something?
