1) Effect of desiccant solution flow rate on moisture removal
Fig. 9 shows the difference in the rate of moisture loss in solution and the rate of moisture gain in the air is affected by desiccant solution flow rate.
The result shows that increase in desiccant flow rate leads to increase in the rate of moisture loss and increase in the rate of moisture gain. This is because higher desiccant flow rate has a higher capacity for desiccant solution to evaporate moisture. However, moisture movement affected by desiccant flow rate is in reverse direction compared with the concentration change affected by desiccant flow rate (see Fig. 4).
The loss and gain of moisture in solution and in the air should be equal because they are tested in the same unit and under the same conditions. However, this experiment shows some discrepancy.
