Abstract

Desiccant cooling can provide control of temperature and humidity, while at the same time lowering the electrical energy requirement for air conditioning. Since the largest energy requirement, associated with desiccant cooling, is low temperature heat for desiccant regeneration, the regeneration process greatly influences the overall system performance. Therefore, the effect of variables such as air inlet temperature, air mass flow rate and initial desiccant concentration on the regeneration process are of great interest. In the present experimental work a high performance bed that combines good mass transfer characteristics with low pressure drop is used. The bed consists of multi-coaxial cylindrical layers made up of cotton cloth as a holder for liquid calcium chloride desiccant. The accumulated mass of evaporated water as well as the solution concentration during the regeneration period is assessed based on the variables listed above. 
The solution concentration and accumulated mass of regenerated water are correlated with air inlet temperature, air mass flow rate and desiccant initial concentration. The functional correlations developed should be useful in the design of such regenerators.
