modelPartialEmpiricalFlowStack

Partial model for empirical expressions with stack effect considered

Extends from AixLib.Airflow.WindowVentilation.BaseClasses.PartialEmpiricalFlow (Partial model for empirical expressions of ventilation flow rate).

Information

This partial model provides a base class of models that estimate ventilation volume flow. The model has indoor and ambient temperature input ports to account for the thermal stack effect.

Parameters
