In the hollow-fiber-membrane-based liquid desiccant air dehumidification process

water vapor can permeate through the membrane effectively

while the liquid desiccant droplets are prevented from crossover. Hence

the traditional problems of desiccant droplet crossover and indoor environmental pollution are solved. In this research

a test rig of the membrane module is built

and the performance of the system is investigated experimentally. The results show that the dehumidification efficiency is in the range of 20%–60%. This is comparable to a direct-contact packed bed dehumidifier. The largest dehumidification rate is about 800 g/h under very hot and humid weather conditions. Moreover

the cooling capacity of the dehumidification is as high as 700 W. Therefore

it performs well even under hot

and humid South China weather conditions.
