NUMERICAL SIMULATION AND ANALYSIS OF PERFORMANCE OF AN INTERNALLY COOLING COMPACT DEHUMIDIFIER

An internally cooling compact dehumidifier (ICCD)was proposed and Aa dynamic two-dimensional nu- merical model describing the heat and mass transfer process of the ICCD has been developed. The dynamic numeri- cal results have been obtained by implicit finite difference method. Meanwhile, several important variables tha strongly influence the performance of the ICCD are identified and, analyzed in details. Thus Eessential theoretical methods for designing choosing proper operation conditions of the ICCD are provided. The results show that the IC- CD has better performance than ordinary packed bed dehumidifier (OPBD).
