綠色建築愈來愈受到重視,預估會以每年10%的速度成長,其中,木料綠建材對環境的友善性非常高,因此其需求量也將大幅增加。本文提出以顆粒或片狀纖維填充形成具開放式孔隙之多孔性木料,其外層則為具穿孔之實木板,搭配風扇形成一具木材香芬與吸濕、除臭功能之半穿透隔間建材,必能增加相關產品的競爭優勢與附加價值。本研究針對多孔性木料綠建材之設計與熱傳特性做有系統的研究探討,先利用實驗方法探討組成結構與組成成份對相關多孔性木料性質的影響,並建立相關的經驗公式,接續則將相關的多孔性質代入進行多孔性材料數值模擬分析,以數值模擬觀察多孔性木料的風阻、降溫與木材香芬送出性能,發現在不同風量穿透下,多孔性木料之類別與長度對其相關功能會有明顯影響,本研究結果可做為此類新穎木料綠建材之重要設計參考。
The green building receives more and more attentions, and will grow continuously in amount with 10% rate per year. Among the different kinds of green building materials, the wooden green building material is very friendly towards the environment. Therefore, the demand of the wooden green building material will increase sharply. This paper proposes a kind of wooden porous material packed by wooden beads or piece fibers with open cell porosities. The outer layers of this wooden porous material are the perforation wooden plates and the inner layer is the wooden porous medium. Coupling with fans, this wooden porous material can insulate the heat, provide the wood fragrance, absorb the moisture and deodorize. Consequently, the competitive advantage and added value of the product will be promoted much more. This work investigates the design of the wooden porous green building material, as well as the corresponding fluid flow and heat transfer characteristics. Firstly, the effects of the structure and ingredient on the properties of the wooden porous material are explored experimentally. The relevant empirical formulas are also built. Hence, the measured properties of the wooden porous material can be substituted into the numerical model and then the numerical simulation can be performance. This work numerically investigates the flow-resistance, temperature-drop and wood fragrance-providing performances. The results indicate that the kinds and lengths of the wooden porous materials influence the relevant performances strongly. Finally, the research finds can be the important base of design for the relevant products.
