Construction and Analysis of Heat-and Mass Exchangers for Liquid Desiccant Systems Novel flat plate and tube-bundle heat and mass exchangers were designed, built, and experimentally examined in combination with an aqueous solution of lithium chloride as a desiccant. Prior to the construction of the components, two test rigs were built for the evaluation of several textiles and liquid desiccant distributors. The first test rig was used for the evaluation of liquid desiccant wicking performance of different fabrics. ...
