Hello,all! I have a question about the simulation of hybrid ventilation using AFN. I built a dedicated outdoor air system. When the system runs, I also set the windows to open by setting the Venting Availability Schedule in the AirflowNetwork:Multizone:Surface. But I didn't define the system in the AirflowNetwork:Distribution. So, is the result correct in this way? I tried to define the system in the AirflowNetwork:Distribution, but I found that I need much information such as the duct and so on. So far, I lack these information. Thanks so mach!
