Numerical simulation and analysis of performance of an internally cooling compact dehumidifier

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