I am trying to model constant volume fan using Fan:SystemModel referring to this discussion
I could connect Fan:SystemModel to Airloop and get the result.
However, result shows that electric power is 0 as below.
Does anyone know what is causing this situation?
Please also find idf part for Fan:SystemModel as below.
