本論文係太陽能空調系統噴射器的設計與製造測試,以CNC綜合加工機實體加工,配合實體數據測量。噴射器的主要設計參數為入口溫度、背吸入端壓力、出口端壓力、噴嘴內截面積比。最後將數值結果與噴射器實體量測數據比較,發現截面積比值為重要的影響參數。噴嘴口徑比,分別為5mm : 7.5mm、3mm : 5mm、2mm : 3.5mm等,對照參數值模擬數據曲線圖,以5mm : 7.5mm噴嘴比例參數最佳。
The thesis aids to study the performance of ejector for solar air-conditioning system by manufacturing and testing the various ejectors. The main design parameters of ejector are the primary inlet temperature, secondary inlet pressure, back pressure, and cross-section area of ejector. Finally, the numerical simulation result with the measurement data indicates that the ratio values of cross-sectional area are more dominant parameters. The ratios of nozzle diameter are 5mm : 7.5mm、3mm : 5mm、2mm : 3.5mm , respectively. Based on contrast curves of numerical simulation result, the optimal area ratio of ejector is 5mm : 7.5mm.
