Novel packing materials for open liquid desiccant system

摘要

The objective of this study is to design and test a liquid dehumidification system that can operate with a maximum performance under atmospheric conditions without any mass transfer problems. For this purpose, polycarbonate panels were used as packing materials in the absorber and desorber innovatively. Polycarbonate has high surface tension among other polymeric based packing materials. This feature can improve the wetting property of liquid desiccant (LiBr-water, LiCl-water and CaCl2-water etc.) and the mass transfer within the system as well. Temperatures of air and liquid sides, relative humidity of inlet and outlet air, velocities of air and liquid sides, variation of concentration of desiccant solution will be measured and investigated to analyze the performance of the system.
