THE FUNCTIONAL ALGORITHM OF VENTILATION SYSTEMS FOR EVACUATING THE SMOKE AND HOT GASES OUT OF A MULTISTOREY BUILDING ON FIRE

摘要

This works offers an algorithm for smoke evacuation out of a multi-storey building inside which it is supposed that the necessary time for people evacuation can be longer than an usually accepted one. The purpose is to avoid a serious smoke contamination of the staircase and of the other floors and also to maintain the smoke layer inside the fire compartment at an acceptable level. The work is original due to the fact that it combines the smoke control systems using a differential pressure between the staircase and the fire floor, applying the method of differential pressure, type "sandwich" between the floors and to use the usual ventilation systems of the building for smoke evacuation.
