The system is divided into dehumidifica¬tion side and regeneration side .The two sides are carefully separated from inside and insulated. There are two air path in the tested system. In the first path, the moist air flows through the absorption part to absorb the moisture from it. This will decrease the concentration of the solution on the bed after a certain time. In the second path in the tested system the air exits from the air heaters at high temperature then flows through the regeneration part in order to regenerate the moisture from the solution. This increase the solution concentration on the desiccant after a specific time. The air performs two processes simultaneously in the system ,namely the dehumidification process and the regeneration process. The rotary part contains twelve ducts . Each duct is covered from the two side surfaces with clothes layer. The thickness of the clothes layer is 1mm and is saturated with calcium chloride solution at initial concentration of 40%.The problem is solution of this model by ansys program.It is definition of properties of calcium chloride solution to the programز
