摘要:	本研究為探討扁平管平行流蒸發器於箱型冷氣及一噸分離式冷氣之應用，研究中採用扁平管平行流蒸發器取代冷氣機中傳統圓管式蒸發器，除了對扁平管平行流蒸發器進行設計外，製作完成扁平管平行流蒸發器並利用開放式風洞測試其性能，以期達到最佳熱傳性能、縮小體積及降低成本之目的。將設計結果與現行空調機使用的圓管穿管式蒸發器比較，在相同熱負載下，五噸箱型冷氣方面蒸發器體積可縮小為傳統60%，一噸分離式冷氣方面蒸發器體積可縮小為傳統48%，但扁平管平行流蒸發器因為凝結水無法順利排除，導致蒸發器整體性能下降，若可以解決積水問題，扁平管平行流蒸發器則可完全取代圓管穿管式蒸發器。 This project will discuss the flat tubes and parallel flow heat exchangers air-conditioner. The traditional round tube evaporator and condenser in an air-conditioner will be replaced by flat tube parallel flow evaporator. In this project not only design the flat tube parallel flow evaporator but also test the flat tube evaporator. The compressor, expansion valve and other components in the air-conditioner will also be modified according to the changes of heat transfer and pressure loss of the heat exchangers. This project will be performed by the cooperation with the TECO Electric and Machinery Co., Ltd. The ME department will design and test the flat tube evaporator and condenser and the TECO will take charge of other components. A compact, low noise and high performance air-conditioner will be developed in this project.
