I modelled a Fan:ZoneExhaust object. I used EMS and made the airflow variable by linking with a variable volume supply fan.
The simulation result shows that the airflow rate and electricity of Fan:ZoneExhaust became variable, but what performance curve is this fan electricity based on?
Unlike Fan:SystemModel and Fan:Variable, Fan:ZoneExhaust does not have an input field of Electric Power Function of Flow Fruction Curve Name.
