Based national defending fire standards,combining with practical engineering design experience,it discusses easily produced defending fire and discharging smoke problems of civil building project design,typically analyzes inside aisle and defending fire valve setting point of ventilating air-conditioning system,and puts forward correlated suggestions to make standard have real-time furthermore.

Suitable condition about the optimization control way for the smoke exhaust of the long internal corridor

A mathematic model of smoke flow in high-rise building is established and a k-ε three-dimensional turbulence model with two equations are used to simulate the effect of smoke-exhausting way and smoke-exhausting position on the smoke distribution in the walkway under the natural ventilation.
