Dehumidification of air can be performed by absorption of moisture in hygroscopic solutions like calcium chloride and lithium bromide. The dilute solution can be then regenerated by using solar energy. The present investigation deals with the theoretical and experimental analysis of a solar regenerator. The effect of normal convective velocity has been studied and it has been found that the mass transfer coefficient is lower when this velocity is considered. Experiments have been conducted with parallel and counterflow regenerators using both lithium bromide and calcium chloride solution and their performance has been compared. Under identical conditions the performance with lithium bromide has been found to be better than with calcium chlorides solution.
