Estimating Air Leakage Through Doors For Smoke Control

Estimating air leakage through doors for smoke control.

Estimating air leakage through doors for smoke control.

The smoke leakage control of. Baffle at leading edge. Realistic smoke leakage control was investigated using actual scale through penetration firestop models installed in a curtain wall and air leakage measurement units. And filament brush seal.

And filament brush seal. A generalized nondimensional relationship for flow through defined narrow gaps is used to predict leakage flow past closed door assemblies. Nondimensional relationship for flow through defined narrow gaps is used to predict leakage flow past closed door assemblies. Single or double sharp 90 bends.

Applications for prediction and design appropriate to smoke control systems are indicated. Typical gap shapes considered include straight through. Knowledge of air leakage is also of importance in estimating the effectiveness of interior doors as barriers to smoke flow and in the design of smoke control systems where stair and elevator. Baffle at leading edge.

The test procedure prescribes that during test the gap between the bottom edge of the door leaf and the floor or threshold is sealed. Typical gap shapes considered include straight through.
