The open liquid desiccant system was designed and constructed. The system was monitored using SCADA
control and automation programme. The originality of this study was using polycarbonate packing materials having
high surface tension which is close enough to surface tension of liquid desiccant. The packing materials were
manufactured with 30o
angle and 43% LiBr – water solution was used as desiccant. Established study includes
preliminary results of the experiments. The constructed system dehumidified air due to low coefficient of
performances. Results indicate that the constructed system needs some modification such as increasing the contact
area between liquid desiccant and air and decreasing temperature of liquid desiccant during inlet of absorber. In
future study, these problems will be tried to eliminate and improve the COP of the system for both definitions.
