本研究建立一套理論模型預測史特靈熱泵製熱行為,並針對現有史特靈熱泵進行性能量測,同時進行機構上之設計改良。理論模型將熱泵分為膨脹室、吸熱器、再生器、放熱器、壓縮室以及水套等六個區間進行分析,並針對填充壓力、轉速、環境因素等參數影響進行探討。實驗方面則建立史特靈熱泵之溫度、壓力與性能之量測系統,最後透過理論與實驗結果進行比較,驗證理論模式的準確度並作為史特靈熱泵設計改良之參考方向。
本研究針對史特靈熱泵原型機進行實驗,驗證理論模型之準確性,在填充壓力為1 bar下,理論與實驗值之趨勢相近,最大誤差約為9%。
實驗值在填充壓力5 bar,轉速500 rpm下有最佳性能係數,由1.63提升至1.70;轉速1000 rpm下,性能係數由1.13提升至1.34。理論值在填充壓力6 bar,轉速500rpm下有最佳性能係數3.12。
This study establishes a theoretical model to predict the performance of a Stirling heat pump and uses the prototype to verify the accuracy of the theoretical model. The theoretical model divides the heat pump into six sections, such as expansion chamber, cooler, regenerator, heater, compression chamber and water jacket, and it discusses the influences of stirling heat pump by varying of the operating parameters such as charged pressure, rotation speed and environmental factors. The temperature, pressure and performance measurement system of Stirling heat pump is established.
Comparing the results, it is found that the theoretical model and experimental results are close at charged pressure is 1 bar. The maximum error between the theoretical model and experimental results is about 9%.
