室內濃煙環境下高功率空氣負離子除煙輔助──逃生系統之研究與設計

Design and Research of the High-power Nega-tive-air-ion Smoke Removal Assisted Escape System in Indoor Dense Smoke Environment

本研究模擬室內火場濃煙環境，架設高功率空氣負離子除煙陣列，藉由量測濃煙中負離子數和PM2.5微粒濃度變化，探討除煙裝置去除PM2.5懸浮微粒之單位效能。本研究也以住宅樓梯空間為實際實驗場域，檢測有無風力輔助下之負離子擴散程度差異，藉以設計應用於室內濃煙環境下之空氣負離子除煙系統，期望未來能將系統重點配置於建築物室內空間中，協助救難人員和逃生民眾在煙霧瀰漫且無機械排煙設備與自然排煙口的環境中，能夠獲得更乾淨的空氣與更佳的能見度，增加寶貴逃生時間。

This study simulated the smoke environment of the fire site and set up a high-power negative-air-ion (NAI) smoke removal array. By measuring the number of NAIs and the change of PM2.5 particle concentration in the smoke, the unit efficiency of the smoke removal array to remove PM2.5 suspended particles was calculated. This study used the residential stair hall as the experi-mental site to detect the difference in the degree of NAI diffusion with or without wind assistance to design an NAI smoke-removal-assisted escape system for indoor smoke environments. It is expected to assist rescuers and escape people in obtaining cleaner air and clearer sight in a smoky environment, increasing the golden escape time.
