Using lithium chloride solution as dehumidification solution, experimentally studies the dehumidification performance of the commercial regular fillers (F-type, P-type and M-type packing) with large specific surface area made of three different kinds of packing materials (fiber paper, PP plastics and stainless steel) on a countercurrent packed-type liquid desiccant dehumidification test bench. Compares the dehumidification performances of the three kinds of packing materials from different perspectives, and develops the empirical correlations of the dehumidification efficiency of the dehumidifiers for the packing materials. The results show that for the packing materials, the dehumidification performance of fiber paper is the best, followed by the PP plastics and that of the stainless steel material is the worst.
