全熱交換器之週期式運轉性能研究

Abstract

本研究擬將再生式全熱交換器的週期式運轉模式應用於回復式全熱交換器，並於入出口加裝蓄熱蓄濕材料，利用週期式運轉，以提高性能表現。另外設計完整的實驗方法與流程以分析各蓄熱蓄濕材料與運轉週期對系統性能之影響。 在週期式運轉實驗中，利用古典單區系統的原理，以加熱盤管與冷卻盤管來模擬室內外空氣狀態，其中蓄熱蓄濕材料為活性碳、純鋁、鋁混活性碳以及未加裝任何材料，運轉週期為5、8及10分鐘。實驗結果顯示本研究所加裝純鋁混活性碳的組合於運轉週期為5分鐘時最能同時有效提高顯熱、潛熱及全熱有效度分別為1.96%、12%及9.98%。

The object of this research is to apply the periodic flow of the regenerator to the recuperator, and put in heat and moisture storage materials in the inlets and outlets of the recuperator, and then improve the performance with the periodic flow. Besides, the method and process of experiment with the periodic flow is conducted to analysis the effect of the thermal storage and mass storage material on the performance of the system. In the experiment, according to the theory of the classic single-zone system, heating coils and cooling coils is used to simulate the state of the outdoor-air and indoor-air. Heat and moisture storage materials are active carbon, aluminum , and aluminum mixed with active carbon. The operation period is 5 minutes, 8 minutes and 10 minutes. The result of the experiment shows that the sensible heat effectiveness, latent heat effectiveness and total heat effectiveness simultaneously increase 1.96%, 12% and 9.98% respectively by putting in aluminum mixed with active carbon as the heat and moisture storage material, while the operation period is 5 minutes.
