常温での測定による加圧煙制御システムの適切さの確認方法

摘要

本研究は加圧煙制御システムが火災時に遮煙できる能力を有するrnことを常温で確認するための方法の確立を目的としている。そのたrnめ、まず開口情報が既知の場合において、火災時の遮煙条件と同一rnの状態を常温で確認できる理論を構築した。%The purpose of this papa is the establishment of the method to confirm at 1he normal temperature that the pressurizarion 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.
