近年在歐美等國家,因室內濕氣所造成的問題漸漸受到世人的彼重視,而許多研究指出利用建材的濕氣緩和效果,可有效地的減少濕氣所造成的相關問題。然而,至今許多濕氣緩和效果的解析方法,均以室內完全擴散的單質點模型爲主,不但無法解析濕氣於室內的分布,亦無法評估調濕建材設置位置與吸放濕效果之差異。本論文針對採用調濕建材時室內濕氣解析之問題提出新的CFD解析法,此解析法於未來可用於探討室內調濕建材的最佳配置位置與設置量,不但可提供學術研究之用,亦可作爲建築與室內設計專業者之參考。並探討藉由此方法評估室內熱與濕氣的分布,以做爲未來探討調濕建材最佳配置與數量的評估工具。
Recently, issues regarding health problems related to dampness in buildings have been widely reported in Europe and America. In some studies, a moisture buffer effect that provides passive moisture control using interior materials was proposed as an effective way to alleviate such dampness problems. Until now, in order to evaluate the moisture buffer effect, a simulation model that assumes the indoor air temperature and humidity to be uniform (complete diffusion) has been widely used. However, when using this method, it is difficult to evaluate the influence of vapor distribution near materials and the contribution of materials in different positions of a room space. In this paper, the authors propose a new CFD simulation model incorporating a coupled simulation method with convection and heat and vapor transportation through interior building materials.
