碩士 === 國立臺灣大學 === 機械工程學研究所 === 97 === 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.
