本研究在一室內環境控制室內建立植生牆，運用植物行光合作用的原理，來吸收室內人呼吸吐出的CO2與改善室內空氣品質。本文選用白鶴芋來作為研究的植栽，並分析出不同CO2濃度下的吸收率，接著以多孔性介值的特性來模擬空氣流過單株植物的流場，並由實驗所得的吸收率帶入多孔性介質的吸收率中，以模擬單株植物吸收的CO2效率，並將實驗結果與模擬結果做比對。再針對實驗室內環境控制室內的植生牆對單人吐出CO2吸收效率，並將不同的CO2濃度下的吸收率代入植生牆植物的多孔性介質模式中，以模擬CO2的吸收效果。本研究模擬結果與實驗結果相吻合，在有無植生牆的實驗中得知5.61m2植生牆可對室內CO2改善了12.14％，而由增長室內的模擬中植生牆面積為14.025m2，能維持2小時良好的室內空氣品質，依趨勢來看，若要淨化單人吐出的CO2需要約19.635 m2的植生牆面積。

This study proposed a vegetation wall in an indoor environmental control room. Based on the principle of plant photosynthesis, a vegetation wall can absorb the CO2 breathed out by indoor workers, thus improving indoor air quality. This study used Spathiphyllum as the sample plant, while simulating a flow field where air flowed through individual plants based on the characteristics of a porous medium. The absorption rate obtained from the experiments was introduced to that of a porous medium to simulate the CO2 absorption rate of the individual plants, and the experimental and numerical results were then compared. In order to understand the vegetation wall’s CO2 absorption rate in an indoor environmental control room, this study used the absorption rate of CO2 under different concentrations in the porous medium the plants, thus simulating the absorption effect of CO2. In this study, 12.14％ of the CO2 concentration in the control room in which only a person lives can be absorbed by the vegetation wall (5.61m2). However, by increasing the area of vegetation wall to 14.025m2, good air quality in the room can be maintained within 2 hours. It is conjectured that a 19.635m2 area of the vegetation wall is required to reach an equilibrium condition in the single person room.
