How to calculate AFN combined natural and mechanical ventilation in Energy Plus

Hi, I want to check the airflow when exhausting air at a constant airflow rate from a particular room and taking in raw outdoor air through a window in another room.(the room is negative pressure ventilation) I made IDF and run simulate but failed with following error messages.

* Severe * The number of entered AirflowNetwork:Distribution:Component:Fan objects is 1

* Severe * The number of entered AirLoopHVAC objects is 0

why I'm getting this error？please tell me.

thanks,
