Comparaison of run time for HVAC system, single duct VS dual duct
I made a basic OpenStudio model with SketchUp.
The objective is to compare the run time for an HVAC system; simple duct VS dual duct.
The result shows that run time of the model with dual duct is about six time longer than a model with simple duct.
What can explain this result?
