九份園區的微氣候應用研究

Abstract

本研究聚焦於新北市九份創新園區小區域微氣候技術之應用，針對園區內熱島效應與戶外熱舒適度降低問題，探討噴霧系統與鋪面配置對體感溫度之改善成效。九份地處山海交界，具良好通風條件，夏季（6 ~ 9月）平均最高氣溫約26.8~28.9°C，濕度高達84 ~ 87%，風速約5 ~ 7 m/s，屬高溫高濕且風力適中的環境，適合導入水霧蒸發降溫技術。研究方法包括CFD風場模擬、Steadman體感溫度模型轉換、實地環境監測與實驗場域測試。實驗設計探討不同季節、噴霧頻率（每2或15分鐘）、噴霧時間（2或10秒）、噴頭高度（0.1m或1.8m）及鋪面材質（樹皮、木屑）之交互效果。結果顯示，夏季高頻短時噴霧搭配低高度噴頭與樹皮鋪面，體感溫度可降超過2°C、濕度提升20%；冬季則以木屑鋪面有助穩定濕度與溫度。園區廊道具峽谷式地形，透過自然風廊引風、植栽遮蔭、地下冷泉與水霧結合，展現良好微氣候調節潛力。整體系統具備模組化、即時感測與智慧控制功能，未來可擴展至都市綠廊、觀光步道等場域。研究亦建議結合展示與教育功能，打造具永續示範價值之氣候友善園區，作為面對氣候變遷與熱島效應的可行策略。

This study focuses on the application of localized microclimate control strategies in the Jiufen Innovation Park, New Taipei City, in response to urban heat island effects and reduced outdoor thermal comfort. Situated at approximately 200 meters above sea level between mountains and sea, Jiufen features favorable ventilation conditions. During the summer season (June–September), average maximum temperatures range between 26.8–28.9°C, with high relative humidity levels of 84–87% and wind speeds of 5–7 m/s. These conditions make the site suitable for implementing mist-based evapo-rative cooling technologies.Research methods included computational fluid dynamics (CFD) simulations, Steadman’s apparent temperature model conversion, on-site environmental monitoring, and spray system performance testing in an experimental field. Experiments evaluated the interaction between seasonal variations, misting frequency (every 2 or 15 minutes), spray duration (2 or 10 seconds), nozzle height (0.1 m or 1.8 m), and surface materials (bark or sawdust). The results showed that high-frequency, short-duration misting at low spray nozzle heights combined with bark pavement could reduce apparent temperature by over 2°C and increase relative humidity by up to 20% in summer. In winter, sawdust helped maintain humidity and stabilize ground temperature.The canyon-like corridor formed between the exhibition center and hillside was identified as a critical microclimate zone. By integrating natural wind corridors, vegetative shading, subsurface cold water, and misting systems, the site demonstrated significant thermal regulation potential. The system developed features modular design, real-time sensing, and intelligent control, offering strong adaptability to various environments. This study proposes extending such systems across urban green corridors, tourist walkways, and climate-resilient public spaces with educational and demonstration value, contributing to sustainable urban climate adaptation strategies.
