PARAMETRIC STUDY OF AN ENERGY-EFFICIENT AIR-CONDITIONING SYSTEM USINGLIQUID DESICCANT

Liquid desiccant can be used effectively to reduce energy consumed in air conditioning (AC). Unlike conventional AC, the latent part of the cooling load is overcome using liquid desiccant. In a previous article , an energy efficient system utilizing CaCl2 as liquid desiccant was p roposed. This study is an extension of that work. The effect of key va riables on the performance of the proposed system is undertaken. The i nlet temperature of the liquid desiccant to the dehumidifier, space se nsible heat ratio, and heat exchanger effectivenesses are the variable s studied. Variations of these parameters and their effects on system performance are presented. Good system performance and energy saving c ould be achieved if proper values of these variables are selected.
