Abstract: An experimental study was carried out to evaluate the liquid desiccant system performance during dehumidification and humidification processes using air injection through the liquid desiccant solution (Calcium Chloride). The air flows cross the desiccant solution with different air mass flow rates. The system is studied at different operating condition (air flow rate, temperature, humidity ratio and solution levels). The effectiveness of the proposed system for both dehumidification and humidification processes were evaluated. Also, the cooling effect and mass transfer coefficient was obtained. It is found that the system effectiveness reached 0.75 in the dehumidification process and 0.7 in the humidification process. Mass transfer coefficient depends on the air mass flow rate and the desiccant solution level in the tank Economical Results of the presented system is estimated
