Property analysis and evaluation indexes of solid-adsorption desiccant system

Based on the concept of independent dehumidification,a system which can test the dehydration property of both the adsorbent bed and the adsorbent has been designed.As adsorbent,the activated alumina and the 4A molecular sieve are used to test the dehydration property of the whole adsorbent bed with two kinds of adsorbent.Finally,three new evaluation indexes about the dehumidification efficiency based on the experimental data are proposed in this paper.
