本研究以6m×5m×2.4m之全尺寸實驗屋，固定火載量為壁裝板材及高低櫃，可動火載量為木框架進行房間火災實驗。實驗屋於天花板設置撒水頭及偵煙式探測器。實驗中改變自然通風開口之面積，與可動火載量位置及重量，以觀測通風與火載量對火災成長及撒水頭與偵煙式探測器作動時間的影響。同時使用FDS進行模擬，並針對FDS參數設定加以探討。
研究中發現，就本實驗配置而言，當開口面積增加則易使火災初期火勢成長迅速，亦造成撒水頭及偵煙式探測器作動時間縮短。而將可動火載量配置於房間角落，使得火勢迅速由可動火載量延燒至固定火載量，使初期火勢增強較為迅速。而撒水頭及偵煙式探測器位於可動火載量正下方及受到壁面效應的影響，均會作動時間縮短。可動火載量不足或距離固定火載量過遠，則無法引燃固定火載量壁裝板材與高低櫃。而可動火載量採垂直堆疊容易產生大量煙氣使偵煙式探測器提早作動，但可能會使撒水頭作動趨緩。
FDS模擬部分藉由改變可動火載量組成及輻射熱釋放比例藉以符合實驗，而結果發現FDS在由可動火載量引燃至固定火載量部份與實驗結果較不符合，有賴於後續的研究。

In this investigation, full-sized fire tests were conducted in a 6m×5m×2.4m room with brick walls. The fixed fire load consisted of hanging cabinets, low cabinets, and wood boards on four walls while the movable fire load was modeled by a wood crib. Sprinklers and smoke detectors were installed and the activation time of each was recorded. The objective of this investigation was the effects of the ventilation and change of the location and weight of the movable fire load on the fire development. At the same time, the room fire tests were modeled using the Fire Dynamics Simulator (FDS). The effects of the parameters of FDS were discussed.
For this setup of experiment, the experimental results showed that the fire growth rate increased and the activation time of the sprinklers and the smoke detectors shortened with the increase of the ventilation opening area. When the distance from the movable fire load to the fixed fire load was too long or when the weight of the movable fire load was too small, the fixed fire load could not be ignited and the fire did not grow. A movable fire load at the corner created a stronger fire than a movable fire load in the middle of the room. The shortest activation time of the sprinklers could be observed when the fire source was at the corner of the room. The smoke accumulating rate increased and the activation time of the smoke detectors shortened as the movable fire load were piled vertically, but the activation time of the sprinkle was delayed.
In the FDS simulation, the composition and the radiation heat release of the movable fire load were modified to match experimental trend. However, the ignition of the fixed fire load differed quite a lot from the experimental observation. More parametric study is needed in the future.
