Vents - Airflow

Airflow tab on Vents Dialog.

 

Enter the discharge coefficient for this vent component. The velocity of the air moving through the vent is given by the standard orifice equation:

 

Where:

v: Velocity

Cd: Discharge coefficient

P: Pressure either side of the vent

ρ density of the air going through the opening

You can select this vent from the Openings model data.

Note: The discharge coefficient is only used in thermal simulations when the Natural ventilation Model option is set to Calculated.
