Using Hot Smoke Tests with Controllable Smoke Volume to Verify Smoke Management Systems with Performance-based Fire Safety Designs
建築物火災煙控性能設計大都以電腦模擬做為評估與認可,結構體與設備完成後偶有地方消防機關會就個案要求以熱煙試驗測試確認其電腦模擬評估效能,本所102 年依澳洲標準AS 4391制訂CNS 15937,已於105 年10 月5 日公告為CNS15937(2016)煙控系統性能現場試驗法-熱煙試驗,惟此法之熱煙僅為示蹤性質,並未規範以實際煙量進行驗證,雖已可較真實性驗證主管機關審核通過之煙控性能設計,但於驗證過程因無法具體以煙量驗證實際設計完成建築物火災發生時可能產生之煙量,故仍難以避免發生有效性之爭議,因此本技術開發可控熱煙量時間歷程方式以及其校驗方法以補此標準之不足。
Most performance-based designs of smoke management systems are evaluated and approved through computer simulation. Occasionally, local fire authorities might require hot smoke tests to be performed on structures and facilities after their completion to verify the effectiveness of computer simulation. In 2013, our institute formulated CNS 15937 in accordance with the Australian Standard. However, CNS 15937 does not stipulate the need to deploy tracer smoke in an amount that simulates real-life fire situations when carrying out a hot smoke test. Indeed, compared to computer simulation, a hot smoke test reflects a real-life fire situation more accurately when verifying the performance of smoke management systems approved by the fire authorities. To compensate for the flaw, we developed a time course method capable of controlling the hot smoke volume used in the test along with the method's calibration mechanism.
