本文的研究工作主要包括以下幾個方面的內容: （ 1 ）綜述了國內外相關的研究現狀和研究背景; （ 2 ）簡介了置換通風的工作原理，並分析了它相對于混合通風的優良特性及評價指標、末端裝置等; （ 3 ）對採用置換通風方式房間的溫度場、速度場和氣流分佈進行了模擬計算與分析; （ 4 ）對採用置換通風方式房間的熱力分層高度進行了模擬計算，並分析其影響因素，如:送風溫度、送風速度、圍護結構傳熱和熱源分佈等; （ 5 ）擬合了無量綱熱力分層高度相應于送風溫度t 、送風速度v 、熱源間距離l和圍護結構傳熱q的經驗公式。The experiment ' s results show that the system is stable under the static pressure control and energy saving under the minimum total supply air volume control. although the terminal dampers ' s tuning time is prolonged under the minimum total supply air volume control, it can be reduced by adopting the appropriate sampling time when debugging the system. from all of this we can conclude thart the minimum total supply air volume control has a good application perspective
實驗結果表明，定靜壓控制方式下系統較為穩定，最小總送風量控制比定靜壓更加節能，但它延長了末端閥位的調節時間，在系統調試時，我們可通過選擇合適的采樣時間來縮短閥門的調節過程，所以最小總送風量控制具有廣闊的應用前景。Ventilation at one end of vault is accustomed used in main workshop of underground hydropower station, the flux uniformity of the outlet influences how the basic network cell model - - - - blast vault should be established in network simulation
