本研究藉由實地量測台灣科技大學內的台灣建築科技中心 (T. B. T. C.) 大樓六樓的室內熱環境，針對此樓層內地板送風系統(Underfloor Air Distribution System)進行供風口速度及風量量測及室內熱環境之垂直溫度場量測。在供風口風速及風量量測方面，探討不同風量條件下，實驗場地內的實際供風量及估算其所對應的換氣率，並將所量測到的實際風量值與廠商所提供的風量值進行比較。在室內熱環境溫度之垂直溫度場量測方面，探討垂直溫度曲線分布和不同量測位置的關係。並透過量測供風口外75 cm、 150 cm 及225 cm 距離的垂直溫度分布，找出垂直溫度曲線較不受供風口影響的距離。藉由更改不同的供風口風量，探討室內垂直溫度曲線分布與供風口風量的關係。進一步探討室內總移除熱量、供風口噴流高度(throw height)位置及溫度分層高度(stratification height)位置。風速及風量的量測結果顯示，空調開啟弱風的條件下，單一供風口風量為0.022 m$^3$/s，空調開啟中風的條件下，單一供風口風量為0.024 m$^3$/s，空調開啟強風條件下，單一供風口風量為0.033 m$^3$/s。室內熱環境之垂直溫度場量測結果顯示，垂直溫度分布曲線受供風口位置所影響，離供風口位置的距離越近，垂直溫度曲線變化越大。當量測位置距離供風口150 cm以外的範圍，垂直溫度曲線較不受供風口遠近所影響。而垂直溫度分布曲線受回風口位置影響較不顯著。隨著風量增加的情況下，垂直溫度曲線上的溫度呈現更一致的現象，溫度分層現象較不明顯。

The research presents experimental measurement results of the indoor thermal environment on the sixth floor of Taiwan Building Technology Center (T.B.T.C.) building.Experimental measurements were conducted in the test chamber utilizing the underfloor air distribution (UFAD) system. The UFAD system supplies conditioned air from the raised floor to the indoor space and hot air is extracted to return vents at ceiling.The research investigates supply air velocity, air flow rate and the vertical temperature distribution in the indoor environment. The experimental results of supply air velocity and air flow rate show that the supply air flow rate for one supply diffuser is 0.022 m3/s for the Q1 option, 0.024 m3/s for the Q2 option,0.033 m3/s for the Q3 option. The results show that the indoor vertical temperature distribution is influenced by the distance between the measuring location and the supply diffuser. When the measuring location is close to the supply diffuser, the vertical temperature profile is influenced by the supply conditioned airflow. When the distance from any supply diffuser is larger than 150 cm, the vertical temperature distribution becomes more consistent. The vertical temperature profile is not affected significantly by the location of return vent. When the supply air flow rate increases, the vertical temperature distribution becomes more uniform and less stratified.
