| Summary: | 碩士 === 國立高雄應用科技大學 === 模具工程系 === 97 === 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.
