The Development of a Functional Pressure Controller in Smoke Management Systems for the Fire Safety of Buildings

화재시 제연 및 피난을 위한 기능성 차압 조절장치 개발에 관한 연구

The smoke and toxic gases generated from the building fires are proved to cause human death. Therefore, the necessity and significance of smoke control have been emphasized, and lots of studies for developing improved smoke management system have been carried out. In this study, the experiments were conducted to evaluated a function and performance in newly developed smoke management system using mechanical pressurization. As a result of this experiment, the differential pressure was 40Pa${\sim}$60Pa and the air velocity through the door was 0.7m/s between safety zone and fire zone. The functional pressure control equipment which could make proper pressure and maintain differential pressure between safety zone and fire zone was developed. And it will give a lot of helps to evacuation activity for peoples in building and fire fighting.
