Performance Enhancement of The Liquid Desiccant Dehumidification System

Abstract

The latent thermal load contributes plays a vital role in controlling the indoor parameters and consumes about half of the total energy in maintaining the thermal comfort for the occupants. Scientist and researcher are continuously looking for a sustainable solution which not only helps in reducing energy consumption but also environmentally friendly. One of the efficient methods adopted in this regard is the liquid desiccant dehumidification (LDD). In this paper, the thermodynamic model of containing two LDD systems; with and without regeneration system is first developed using waste heat as a source. Then the performance of each system is compared on the basis of their humidity ratio, relative humidity, temperature of supply air and condensation rate in the dehumidifier. According to results, it has found that the overall COP with and without regeneration system reaches to 1.165 and 0.566, respectively.
