THE METHOD OF CONFIRMING THE PERFORMANCE OF PRESSURIZATION SMOKE CONTROL SYSTEM BY MEASUREMENT AT NORMAL TEMPERATURE

Abstract

The purpose of this paper is the establishment of the method to confirm at the normal temperature that the pressurization smoke control system is able to block off smoke in case of the fire. A theory is constructed to determine the opening condition of smoke insulation door at the normal temperature which realizes the air flow rate equivalent to that in case of the fire. Although the opening information in the actual building usually does not agree with that in the planning, it is necessary to know the opening information in the actual building. Therefore, in this paper, we propose a procedure to know the opening information by two measurements at normal temperature., and the same time, to judge whether the system is able to block off smoke in case of fire. Moreover the simplified method is proposed for evaluating the performance to block off smoke only from the measurement of one case where the door is fully opened door at the normal temperature. As shown in the example, it would be possible to judge the appropriateness of pressurization smoke control system based on the result of the measurement at the normal temperature.
