論文名稱: 太陽能集熱板暨複合式系統應用於寒流期間以降低魚塭之寒害損失 / A study of solar combisystem deployed in an aquatic farm for mitigating hypothermia damage during cold stream event
中文摘要:
再生能源加熱系統可維持養殖魚塭水溫以防止養殖生物凍死,但寒流期間加熱整個魚塭並不實際,故於池中提供局部適溫的「生存區」較為可行。本研究以STAR-CCM+模擬極端天氣下魚池的三維溫度分布與生存區體積,並以田口法就八個參數中選出的四項(入口高度、出口位置、擋板長度與位置)優化魚塭幾何,使生存區增加40%;另以TRNSYS比較鍋爐、熱泵加鍋爐、太陽能加熱泵加鍋爐三種系統的製熱量、成本回收期與CO2排放。結果顯示太陽能複合式系統雖能減碳但不經濟,鍋爐加熱系統最適合優化後魚塭的寒流期間使用,特別是即時加熱。
英文摘要:
This thesis studies a solar combisystem for an aquatic farm facing cold-stream events, where heating an entire pond is impractical and a localized warm "survival zone" is a better solution. STAR-CCM+ simulates the three-dimensional temperature field and the survival-zone volume, and the Taguchi method optimizes the pond geometry using four of eight compared parameters (inlet heights, outlet positions, barrier length, and barrier position), increasing the survival zone by 40%. TRNSYS compares boiler, heat pump with boiler, and solar plus heat pump with boiler systems in terms of heating gain, payback period, and CO2 emissions. The solar combisystem cuts CO2 but is not economical, so a boiler system is most suitable for the optimized farm, especially for instant heating.
