We are trying to model a dedicated outdoor air system that modifies its flow based on a time of day schedule.
By adding a fractional schedule to the Maximum Fraction of Outdoor Air Schedule Name in the Controller:OutdoorAir object, this achieves the desired reduction in outdoor air. However, the flow in the AirLoop itself does not change and the system becomes a recirc systems at hours where the max OA fraction is scheduled to be less than 1.
As a result we don't see the fan power savings we expect, and also now have to contend with recirc air which isn't real. Is there a way to get the whole air systems flow rate to follow our fractional schedule?
