Network simulation for relationship of pressurized supply air rate and pressure difference across the door

Taking a twenty storied highrise building for example, uses a multizone network model to simulate the relationship of the pressurized supply air rate and the pressure difference across the door under various pressurized conditions, providing a quantitative analysis method of evaluating the availability of the smoke control system. The result shows that the pressurized supply air rate has a significant effect on the pressure difference across the door especially the door in the fire floor.
