本論文致力研究於環保節能熱驅動噴射式製冷系統的性能提昇,系統以非電力的熱驅動噴射器取代傳統壓縮機,且設計出一套1RT(3.5kw)噴射式製冷系統,並使用環保冷媒R365mfc作為系統之工作流體。系統性能提昇主要在噴射器的抽吸比性能,本研究採用圓弧形入口擴散器以取代既有的錐形入口擴散器。已提昇噴射器抽吸比性能10%~13%,已達到改善噴射器集系統性能之效果。
太陽能空調系統監控與集熱性能測試研究方面以建立初步半自動化和性能測試;且針對所監控到的太陽能冷氣系統其集熱性能資料做分析,以在未來建立大型集熱系統的測試標準。

This study dedicates to develop a heat-driven ejector type of air-conditioning and promotes its performance. The air-conditioning adopts refrigerant R-365mfc which is friendly with our environment. The study adopts an arc inlet for ejector diffuser instead of a existing inelet for ejector diffuser, to improve ejector performance entrainment ratio ω and its system performance. The method increased entrainment ratio ω by 10%~13%.
We also developed a computer monitor system to automatically operate the jet system. In addition, the study also analyses the monitoring data of the system in order to set up the test standard for a large size of solar collector system in the future.
