Estimating Air Leakage Through Doors For Smoke Control

Typical gap shapes considered include straight through.

Estimating air leakage through doors for smoke control.

Applications for prediction and design appropriate to smoke control systems are indicated. The test procedure prescribes that during test the gap between the bottom edge of the door leaf and the floor or threshold is sealed. And filament brush seal. And filament brush seal.

Single or double sharp 90 bends. 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. Nondimensional relationship for flow through defined narrow gaps is used to predict leakage flow past closed door assemblies. Fire safety journal 17 1991 171 177 estimating air leakage through doors for smoke conirolt daniel gross center for fire research national institute of standards and technology gaithersburg maryland 20899 usa abstract a generalized nondimensional relationship for flow through defined narrow gaps is used to predict leakage flow past closed door assemblies.

Typical gap shapes considered include straight through. Estimating air leakage through doors for smoke control. The smoke leakage control of. Baffle at leading edge.

Prediction of the flow of air through gaps around exterior doors is of considerable importance in determining ventilation rates and heat losses in buildings. Baffle at leading edge. Single or double sharp 90 bends.
