Design of new cost-effective and sustainable dehumidification systems is important for both energy savings and environmental impacts. This paper analyzes the economic feasibility study and environmental impacts of two different dehumidification systems A and B. These systems are referred as; desiccant system and traditional vapor compression system; respectively. The present worth value and the payback period are used to compare the two systems economically. On the other hand, the weighing methodology of the environmental priority strategies (EPS-2000) has been used for evaluating their environmental impacts. The analysis shows that system A has a payback period of 7 months with annual running cost savings of about 32.5 % compared with system B also, the overall environmental impacts of system A are nearly 0.68 of that of B. The maximum value of LCC for system A and B is 3860 $ and 5440 $; respectively at the end of cycle life. Also, the LCS reaches to 1314 $ at the energy cost 0.05 $/KWh and 2109 $ at the energy cost 0.083 $/KWh.

Keywords: Economic study; Environmental impact assessment; Life cycle assessment  desiccant dehumidification; liquid desiccant.
