Introduces the common methodologies that are used in room airflow simulation. Pointed out that Zonal Model is a kind of methodology with good prospects. Addressed a kind of Zonal model basing on the concept of grid reference pressure and pressure difference between adjacent grids. Modeling results for different ventilation cases show that this Zonal model is simple, time saving and can be used in practice.
