RE: [EnergyPlus_Support] Variable flow series powered induction unit





The series fan powered boxes are in the zones and a VAV system provides primary air to the building. Is there a zone fan system that is variable volume/variable speed?

AirTerminal:DualDuct:VAV ?
And on the AHU side, I guess you need one Airloop with two supply fans in parallel, one for the hot deck and one for the cold deck. I'm sure you can choose what kind of fan, but I've never had to model this configuration.

We have a project that specifies series fan powered boxes with ECM motors that are variable speed. In dead band, the fan flow is at the minimum, ramping up based on the difference between room setpoint temperature and room temperature. The maximum heating flow is 2/3 of the maximum cooling flow.

 

The InputOutput Reference states the fan type must be constant flow but I am wondering if you could work around this restriction with an EMS strategy?
