摘 要
台灣地區地處亞熱帶,所以高濕度的危害也就特別明顯。目前國內探討濕度問題的學者專家不多,一般都著重在溫度的範籌,以控制溫度來滿足人類的舒適。只有IC相關半導體的電子、光電或生化科技等特殊產業才有同時對溫度與濕度做控制,以維持一定之溫濕度範圍,殊不知濕度本身對生活環境亦有莫大的影響,高濕除了使人不舒適外亦會造成霉菌、病菌的大量滋長,破壞建築結構,減低其壽命,故濕度危害環境品質之程度並不亞於溫度。
本研究從濕度之觀點出發,探討濕度對人體,對環境的影響並找出濕度在室內空間的傳輸現象,並將其模式化,進而提供一套可分析不同建材的程式,利用國內常用的多孔性建材為樣本,並配合水氣吸附、釋放的基本理論建立熱與水氣的傳輸模式,以了解熱與水氣在建材內的變化。配合水氣滲透的基本理論推導建立微分滲透特性之統御方程式的數學模式,再將此數學模式利用數值方法發展為電腦模擬程式,以用來預測建築物內熱和水氣之變化。再針對模擬的結果與其它文獻的實驗資料做比較以確認模擬之可信度。
此電腦程式可使建築設計者容易掌握室內的水份含量,克服空調負荷估算的盲點,進而設計出一套合理且最佳化的空調系統,並可利用建材之吸濕特性來做為濕度控制之工具,以建立一既省能又環保之綠色生活環境。
關鍵字:濕度,滲透,吸附,釋放。
ABSTRACT
The high humidity problems are very significant in Taiwan area. However, not many research focused on this kind of topics. Usually, the temperature control is common way to remain the thermal comfort of the people. Only some of the electric industrial factories are aware of the humid problems. The humid indoor climate will reduce occupant comfort and increase the probability of allergenic are pathogenic illness.
This research started from humidity control strategy and discussed the impact of humidity on human. A vapor transport model will be developed in this theses. This model included the differential permeability, moisture transport property, and moisture adsorption and desorption processes. A computer model was developed and simulated the variation of vapor and heat inside materials. In order to validate the simulation results, the comparison between prediction and others references was undertaken.
The model can assist designer to understand the indoor moisture contain and overcome the shortcoming of cooling load calculation. Also, we can apply this model to evaluate the possibility of using green materials to control the indoor humidity.
