火災一旦發生,往往造成嚴重的生命與財產損失,因此,能在火災發生初期抑制火勢之自動撒水系統,對於居室火災安全扮演著非常重要的角色。本研究首先利用火災模擬軟體FDS模擬實尺寸實驗屋火災,以驗證FDS撒水頭模式之準確性與合理性,接著利用FDS模擬不同火場參數之辦公室火災情境,探討有無撒水系統的設置對火災熱釋放率、空氣溫度之差異性以及對人員安全之危害程度,在瞭解FDS在撒水系統模擬之功能後,再進而模擬自動撒水系統對住宅廚房火災延燒之降溫效能,並探討撒水頭數量與配置的不同,對火場降溫成效的差異性及其溫度對人員安全之危害情形。撒水系統的設置,能降低空氣溫度以達到延遲和阻止火場發生閃燃,進而爭取人員更多逃生時間。在廚房撒水頭數量與配置研究案例的FDS模擬中,假設撒水頭水源不虞匱乏,由2000秒後火場上層與下層空氣穩態溫度的模擬結果顯示:依照規範計算所得之三顆撒水頭配置其大部分對火場的降溫效能較單顆與兩顆撒水頭的配置為顯著。
Once a fire occurs, it usually causes serious casualty and property losses. Therefore, automatic sprinkler system which can suppress fire at the very beginning plays an important role for building fire safety. In this study, a fire simulation software FDS was utilized to simulate a full-scale experimental house on fire in order to verify the correctness and rationality of the FDS sprinkler model. Various office fire scenarios with or without installation of automatic sprinkler system were simulated by FDS to investigate the danger level to personnel safety and the differences of heat release rate and air temperature. After knowing the capabilities of automatic sprinkler system simulations by FDS, the temperature decrease effectivenesses of using different sprinkler number and various sprinkler arrangements for residential kitchen fires were investigated. Using automatic sprinkler system could decrease the air temeperature and coud delay or stop flashover in fire. Therefore, more escape time can be extended for personnel in fire. Assuming the sprinklers can provide water continuously, the FDS simulations of sprinkler number and arrangement for a residential kitchen case study show that the temperature decrease effectivenesses of most three sprinkler arrangements calculated by code are more notable than the one and two sprinkler arrangements according to the simulation results of the upper and lower air temperatures after 2000 seconds.
