遠紅外線材料應用於冰水主機之性能分析

本研究之目的為藉由遠紅外線材料致使冰水主機能達到節能減碳的效益，並採用外掛包覆的方式將遠紅外線材料披覆於冰水主機之熱交換器上，藉此以非破壞性的裝設方式達到節能與工程應用的可行性。實驗中為藉由套管式熱交換器在相同的入水水溫、流速與熱交換面積下進行熱交換效益比的探討，最後應用於冰水主機系統上，藉此了解實際應用中遠紅外線材料對系統的COP及冷凍能力的影響與可行性分析。實驗結果顯示，使用商用遠紅外線材料應於套管式熱交換器上在雷諾數為1500時，其能達到4.4~8.8%的熱交換效益提升；雷諾數為3500時，其能達到7.8~13.4%的熱交換效益提升。在冰水主機的實際量測結果中，得知其最高擁有11.9%的COP提升效益與14.4%的冷凍能力提升效益。本實驗所使用的遠紅外線材料確實能提升熱交換裝置其運轉時之效益，並且能使用外掛包覆的裝設方式，能大大的提升未來實際應用的可行性。

The purpose of the study is to achieve the effects of energy saving and carbon conservation for chiller through the use of far infrared material. By the way of external coating, heat exchanger of chiller can be cladded by far infrared material. Such a non-destructive installation way is feasible to achieve energy saving effect and apply to engineering. Experiments were made to explore heat exchange efficiency ratios of tube exchangers under the same influent temperature, flow speed and heat exchange area. Finally, far infrared material was applied to chiller system so as to understand the effects of actual application of mid- and far-infrared materials on the COP and refrigerating capacity of system, and analyze the feasibility of such application. Experimental results show that when Reynolds number is 1500 during application of commercial-use far infrared material to tub exchanger, heat exchange efficiency rises by 4.4~8.8%; and when Reynolds number is 3500, heat exchange efficiency even rises by 7.8~13.4%. As known from the actually measured results of chiller, the system has its COP grown by 11.9% and its refrigerating capacity risen by 14.4% maximum. The far infrared material employed in the experiments of the paper can really enhance the effectiveness of heat exchange device during operation. Meanwhile, external coating is an ideal installation way since it can greatly raise the feasibility of its actual application in future.
