Experimental Investigation of Electrical Conductivity of Liquid Desiccant Solution

Abstract:

Liquid desiccant cooling system is a novel air conditioner with good energy saving potential, which should be a promising choice to meet the needs of cooling and moisture loads. Among all regeneration methods, ED regeneration method should be a promising choice for liquid desiccant cooling system. In this paper, systematic experiments were carried out to investigate the electrical conductivity of desiccant solution. Experimental data of electrical conductivity of desiccant solution is acquired in the experiment, which will be greatly helpful to the energy analysis of ED regeneration system. The experimental results show that the energy consumption in the concentrated chambers is more than others for ED regeneration system cells. Moreover, increasing the temperature of desiccant solution may be a measurement to reduce the energy consumption of ED regeneration system.
