Experimental research on dehumidifier using LiCl solution as liquid desiccant

In this paper, the advantages and dehumidification mechanism of liquid dehumidification were analyzed. The characteristics of the dehumidification equipment were studied through test, and the relationships between temperature and concentration in inlet solution and temperature and the amount of moisture in outlet air were obtained, offered reference and guide for the design and equipment operation of the domestic dehumidifier. In choosing parameters of inlet solution, the temperature of inlet solution is 2～4℃ less than the temperature of outlet air, and the concentration of inlet solution is 1%～3% less than the equilibrium concentration of parameter in outlet air.
