The influence of the inlet solution concentration, solution flow rate, inlet air flow rate and temperature, air humidity on the absorbed process were studied for different liquid desiccants (calcium chloride, lithium chloride and calcium chloride mixture), and the dehumidifying effects of various mixture ratios on lithium chloride and calcium chloride mixture were also analyzed. The results show that the CELD (Cost-Effective Liquid Desiccant, the mixture ratio is 1:1) is more economical than pure lithium chloride solution, while its dehumidifying performance is better than calcium chloride solution.
