Study on Smoke Ventilation Performance According to the Opening Rate in a Corridor-Type Apartment

Abstract

In case of household fire in in a corridor-type apartment, when the apartment door is opened smoke generated from the fire flows along the corridor, which is an evacuation passage, thereby considerably affecting evacuation safety. It is essential to prepare smoke control measures for the evacuation safety of occupants. In this study, a model corridor was constructed to examine the smoke ventilation performance according to the opening ratio of windows installed in an apartment corridor, and a small-scale empirical fire experiment was conducted to determine the changes in smoke concentration, thermal flow temperature, and smoke layer thickness. Additionally, the smoke ventilation performance was examined in the presence or absence of a sprinkler system under the same conditions. Comprehensively considering the results obtained in the experiment, it is desirable to secure a 100% opening rate of the corridor on the 15th floor and below without sprinklers in corridor-type apartments, exempt from smoke control equipment, and in accordance with related standards.
