由於過去幾年數值模型的進步，使得暖氣空調系統（HVAC&R)的產業能夠 預測氣流和溫度，因此本文利用ANSYS Fluent軟體建置地下空調系統模型（其系 統位於馬尼拉王城區中馬布爾技術學院的菲律賓通風與冷凍空調工程協會 (PSVARE)研究室），藉此預測地下空調系統的速度成形和流體分佈，並比較 系統試運行時的資料和計劃剛完成時的空氣平衡資料，本研究將提供模擬試驗的 數據將作為上述設施改建所需。

Increasing trends and improvements in numerical modeling has been evident in the past years especially for the HVAC&R industry where airflow and temperature profiles are being predicted. The purpose of this paper is to build a numerical model using ANSYS Fluent Software to predict the velocity profiles and flow distribution caused by the Underfloor Air Distribution (UFAD) module inside the Philippine Society of Ventilation, Air-conditioning and Refrigeration Engineers (PSVARE) Air-conditioning Laboratory in Mapua Institute of Technology. The model had been compared with the data obtained from the original commissioning report and air-balancing data obtained when the project was completed. The said facility will be renovated and used for experiments requiring numerical models and this study presents the baseline of such.
