Abstract

Analyses are presented for air dehumidification using a liquid desiccant system. The expression for the coefficient of performance of the system is derived in terms of the operating and design parameters where the effect of each parameter can be directly identified. Also, the expression for the maximum coefficient of performance expected from the system for a given operating condition is deduced. The operating ranges of flow rates of air and solution are examined. A methodology is presented to determine the optimum air temperature for the reconcentration of liquid desiccant, and the optimum flow rates of air and solution in the system. In addition, a parametric study is carried out to find out the factors that contribute to the improvements of the coefficient of performance.
