Mathematical model represents all the important features of the system for the purpose of deriving the mathematical equations governing the system’s behavior. This paper describes a simple mathematical model for the preliminary design of an air dehumidification and regeneration process occurring in a structured packing using liquid desiccant cooling technology. With the help of control volumes of dehumidifier and regenerator, mass balance and energy balance equations have been derived for both the components of liquid desiccant system. These governing differential equations will be used in simulation of dehumidifier and regenerator. Performance measures of dehumidifier in terms of mass of condensation of the air and dehumidification effectiveness have been developed. Mass of evaporation of the air and regenerator effectiveness has also been developed to measure performance of regenerator.

Keywords: Dehumidifier, regenerator, Mathematical model, Performance measures, mass of condensation
