Has anyone modelled night purge (night ventilation) in EnergyPlus using AvailabilityManager:NightVentilation?
I ran two ExampleFiles: 5ZoneNightVent1.idf and 5ZoneNightVent3.idf (V25-1-0). Night purge is not modelled in 5ZoneNightVent1.idf and modelled in 5ZoneNightVent3.idf.
I got exactly the same annual cooling end use from the two files, which suggests that night purge in 5ZoneNightVent3.idf is not working.
The simulation results show that the fan operates at night when the condition allows, but the outdoor air is not reaching each zone. Only 4 nodes in OutdoorAir:Mixer have 0.5m3/s airflow during night purge. Other nodes have no airflow. This may be a bug.
