The study intends to test the ability of adsorption for different kinds of absorbent in summer, such as honey-comb type of silica, silica, activated alumina and molecular sieve-packed bed. The main purpose of the study is using different air velocity and adsorption temperature to obtain the optimization of adsorption and desorption time. In addition, the study also developing a periodic operation of total heat exchanger in order to obtain the performance of each adsorbent. The study discusses different types of adsorbent in a fixed condition. In the case of higher air velocity and adsorption temperature, all the adsorbent have better performance compare with the lower one. Especially the activated alumina which has maximum adsorption rate of 17.2 g/min but with minima desorption rate in average time of 50 minutes. While for honey-comb type of silica, it has the highest adsorption rate of 16.1 g/min at 10 minutes. For silica packed bed, it has 12.3 g/min at 15 minutes. But for molecular sieve-packed bed, the desorption temperature is too low to conduct the desorption process. According to the experiment measurement of the periodic operative total heat exchanger, the sensible effectiveness of all kinds of the adsorbent will decay as the periodic time increased. For all the adsorbent, the honey-comb type of silica has the highest sensible effectiveness and latent effectiveness of 98% in 5 minutes. For silica packed bed and activated alumina packed bed, both of them have maxima latent effectiveness of 87% each at 10 minutes. The patent of this study is applied.
