Abstract: The dehumidification efficiency of the ultrasound atomization dehumidifying system with liquid desiccant was studied experimentally. The effects of quality concentration of calcium chloride and lithium chloride mixture solution, liquidair ratio and air-liquid reaction time were analyzed according to the experimental data. It is found that the dehumidification efficiency of this system is 18.1%~26.9% under 9 groups of experimental conditions; the efficiency decreases when the salt quality concentration decreases from 38% to 35%; the liquidair ratio greatly affects the dehumidification efficiency, which increases 50% when the liquid-air ratio increases from 0.18 to 0.84; increasing the reaction time helps improve the efficiency. Moreover, the temperature of the processed air is raised when the efficiency increases.
