Experimental study on dehumidification performance of liquid desiccant systems

Through orthogonal experiment design, experimentally studies influences of mass fraction and temperature of inlet liquid, inlet liquid-air ratio, and humidity ratio and temperature of inlet air on the humidity ratio of outlet air. The results show that the first four factors affect significantly the dehumidifying capacity, and the effect of inlet air temperature is week; when the inlet liquid-air ratio value is smaller, the dehumidifying capacity increases along with the inlet liquid-air ratio; when the inlet liquid-air ratio is larger than 1.5, the dehumidifying capacity does almost not change along with the inlet liquid-air ratio; the sequencing of the five factors in the influence on unit dehumidifying capacity from large to small is the humidity ratio of inlet air, mass fraction of inlet liquid, temperature of inlet liquid, inlet liquid-air ratio and temperature of inlet air.
