摘要:	由於現今節能和環保意識的抬頭，而屬於高耗能及環保問題的空調系統，如何能提升空調系統的性能效率和環保功能的目的，來達成節能、高效率的目標。本次實驗主要是使用R410A冷媒做為工作流體，搭配不同的流量和不同的管路系統配置在鰭管式熱交換器進行性能實驗，在實驗研究中發現R410A 冷媒，於熱交換器中，在管路分流數較多時，由於提升了熱交換器管路系統溫度分佈之均勻性，使得熱交換器性能也愈好。而在順向流和於逆向流的不同管路系統配置，R410A冷媒也具有不同的性能表現，實驗結果顯示以五進五出、逆向流的管路系統配置方式，其性能是最佳的。藉由實驗研究，來了解R410A冷媒的工作特性，在不同的管路配置方式時，對於熱交換器的效能都會有不同的影響，希望可以做為空調業界，在 R410A冷媒開發時的設計參考，而設計出高效能、低成本的熱交換器的配置。 Nowadays, in consequence of the energy shortage and the eco-awareness, it makes more important to emphasize on how to improve the efficiency and also get the purpose of eco-awareness for the air conditioning equipment which is high energy consuming and environmental damaging. The main purpose of this experiment was taking the R410A refrigerant as mass flow with different flow rate and circuit arrangement to process the performance experiment of fin tube heat exchanger. The result of the experiment turned out that the R410A refrigerant in the heat exchanger, attributable to the more number of circuits which could average the temperature of heat exchanger circuit system, the better for the heat exchanger performance. With different allocation of circuit system in forward flow and counter flow, there were different performances in the R410A refrigerant, the experiment result shows that when the circuit system arrange as 5-circuit and counter flow , it would demonstrate the optimal performance We could find the operation characteristics of 410A refrigerant from the experiment results it would provide different effects for the heat exchanger with various methods of the circuits. In the future, our long-term goal is to make R410A refrigerant as an important design reference and also to promote this high efficiency and low cost material in the field of air-conditioner.
