A Demonstrational Test of Pressurization Smoke Control System at A Large-scale Shopping Store

Abstract

This report deals with a performance test on a pressurization smoke control System at the first large-scale shopping store in which installed it. If a fire breaks out in the store, it controls the smoke movement not to leak the smoke into the other compartment, other floors and vertical shafts by pressurizing their air. Generally speaking, it was difficult to use the system at a large-scale shopping store because of difficulty with getting enough airtight there. But we could get enough it by an adequate management from the stage of construction. The performances of the system, for example the airtights, the performances of smoke extraction devices and pressure devices and the differences of pressures between fire compartment and other compartments or vertical shafts, were mostly confirmed through the test.
