<br>Dear sir,<br><br>My question is regarding the calculations used in the AirflowNetwork model. In the calculations for Pressure and Airflow (regarded as the first step of this model in the Engineering Reference Document), it is used two values of air density (for inside and outside) for objects "AirflowNetwork:Multizone:Component Detailed Opening" and "AirflowNetwork:Multizone:Component Simple Opening". My question is:<br><br>Do these two values of air density vary according to the temperature of the inside and outside, respectively? And if not, in what way does the calculation for air flow take into consideration the stack effects? thank you for you time to answer these questions.<br><br>With kind regards,<br><br>Pedro Peixeiro.<br>
