大屯山區溫泉氣體中硫化氫在建築室內空間中分布擴散之研究
Research of the Interior Proliferation of the Hydrogen Sulfide of the Hot Spring Gas in the Datun Mountainous Area
摘要
民眾在從事溫泉休閒活動時，不僅會接觸溫泉水，也會直接呼吸到溫泉所散發出的氣體，尤其是在台灣每年都有些工人因清洗溫泉槽，暴露在高濃度硫化氫環境下而猝死的案例。因此，為保障國人在從事溫泉休閒時之健康環境，擬從此一角度出發探求人體接觸溫泉所散發之氣體時是否會對人體造成影響，如何讓人在享受溫泉水所帶來健康成效之餘，同時避免溫泉硫磺氣體對人體之呼吸系統產生之負面影響，更進一步地尋求有效解決之道來改善此負面之情形。 本研究方法擬採用實際檢測調查法，後運用模擬軟體模擬比對為輔助，選擇於陽明山大屯山區某溫泉旅館之溫泉套房進行個案硫磺氣體調查量測，分別進行不同高度及時間點上之實測，並將其結果套繪於Mapinfo軟體上，分析了解室內硫化氫之分佈狀態與擴散行為，再利用FLOVENT軟體進行室內風場行為之模擬，並依結果發現問題以尋求減量改善之方式與設計成效，提供溫泉建築室內環境舒適品質之參考依據，給予遊客在從事溫泉休憩活動時之保障。 本研究結論是: 1、檢測結果顯示高濃度硫化氫可在通風良好狀態改善下逸散。 2、研究使用建築設計手法使硫化氫濃度之降低改善。 3、考量浴池中硫化氫之其氣體流動狀態與人體呼吸高程之關係，以避免硫化氫之影響。 4、舒適溫標之納入考量，求得自然通風換氣、室內氣溫及空調節能之最佳平衡點，使整體環境舒適度更能提升，維持高品質之泡湯環境。 5、室內空氣品質建議值之考量應納入硫化氫之濃度品質建議值管制，配合目前公佈之十項參考值，以利於在國計民生愈來愈重要的溫泉觀光產業趨向高品質健康環境概念。

The people not only contact hot spring but also directly breathe the gas from hot spring while they enjoy their hot spring activity. The case happened in December 29, 2005, especially indicated the affect of exposing in highly concentrated hydrogen sulfide environment. A family with 4 people suddenly died when they took high hydrogen sulfide in Tian Xiantang city, in the north of Tokyo. Therefore, in order to safeguard the people and provide people a health environment for taking hot spring, this research focuses on the affect of the hot spring gas to the human body and how to avoid the negative influence while people enjoy the healthy benefit of the hot spring. Meanwhile, this research seeks an effective solution to improve the harmful situation. The research conducts an actual examination, and then utilizes software to simulate and estimate the result. Firstly, the initial data obtained from a real felid experiment in a hot spring suite and the researcher relies on the analysis of Mapinfo and Flovent understanding the distribution and proliferation of the hydrogen sulfide. Secondly, by simulating the pneumatic fluid, the researcher proposes the root causes and suggests the improvement plan and design that offer a reference for establishing a comfortable and safety indoor hot spring environment. The conclusions of this research: 1. The examination result shows the highly concentrated hydrogen sulfide may dissipate in a space with good ventilation. 2. The hydrogen sulfide density may be reduced by using the natural ventilation. 3. The architectural design can accelerate reducing the density of hydrogen sulfide. 4. By considering the air fluid of hydrogen sulfide and the breath level, this research recommends a bath should be design under floor in good ventilation. That is can result in lower density of hydrogen sulfide. 5. The consideration of setting a comfortable indoor temperature contributes the balance of the natural ventilation requirement, interior temperature and the energy economy. That not only upgrades comfort but also keeps a high quality hot spring environment. 6. In addition to the published 10 reference values, recommended value of indoor air quality should be listed in the regulation of hydrogen sulfide. That will lead Taiwan’s hot spring industry to be a high quality and healthy tourism.
