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, liquidair 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 liquidair 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.
