displacement ventilation in Energyplus get strange result [closed]

asked 2022-01-13 01:55:47 -0600

this is also my first time trying displacement ventilation, i can run the file and get the results. I tried 2 situations, one with DV and one without DV. The room places in interzone of the building and has almost whole year cooling demand. But the energy demand with DV has no advantage as the mixed one, this is not fit for my understanding of DV. Shoud I give a smaller ventilation demand for outside air to the DV model? I was wondering a result with smaller energy consumption for DV with same values for other settings.

How can i upload the idf files here? Thanks
