In this paper, the size and performance of a dehumidification tower were studied by simulating varying
operating conditions. Based on the experimental results, this study presents the performance of a
packed tower absorber for a lithium chloride desiccant dehumidification system. The effects of the main
variables - airflow rate, liquid desiccant flow rate, and inlet air temperature on the rate of
dehumidification were reported. It was found that the influence of these variables could be assumed to
be linear. A finite difference model was developed to determine the packing height of the
dehumidification towers. This model was worked out in MATLAB code, which is a suitable model for
measuring the optimum height of a tower. The validity of this model was compared with published
experimental data and our data. Comparisons between the simulated packing height and the actual
packing heights used by experimental studies illustrated that our finite difference model is acceptable.
With this model, we predict the packing height for every condition, and then we constructed the
dehumidifier based on the results of our finite difference model.
