Summary

This paper develops a liquid desiccant dehumidification experimental facility. Tests on the dynamic characteristics of the dehumidification process are conducted on the counter-flow structured packing dehumidifier. The time constant of the dynamic response is defined to characterize the dynamic processes. Experiments with different inlet conditions show that time constants of the outlet air humidity ratio and temperature are not always equal. The transient time can be up to 250 seconds before the outlet variables of air achieve steady state. The dynamic responses of the outlet humidity ratio and temperature to the step changes of the mass flow rate of solution are also tested. The experimental results and analysis can be used for modeling validation of liquid desiccant dehumidification processes.
