Energy saving potential of a solar assisted desiccant air conditioning system for different types of storage

In this study, the performances of a solar energy assisted desiccant air conditioning system with different types of storage materials are numerically investigated. In this study four types of storage materials (paraffin wax, stearic acid, capric-palmitic, and CaCl2<bold></bold>6H(2)O) are used to obtained the better storage materials can be use for a solar energy assisted desiccant air conditioning system. The numerical results show that, at the same operating conditions the average percentage of energy saving potential approximately reached to 75.86%, 78%, 72.4%, and 64.6% for using paraffin wax, stearic acid, capric-palmitic and CaCl2<bold></bold>6H(2)O as a thermal storage materials, respectively as compared to the case without storage materials and solar energy. The life cycle savings reached to 1727.5, 1997.6, 1766.1, and 1534.6 $for using paraffin wax, stearic acid, capric-palmitic and CaCl2<bold></bold>6H(2)O as a storage materials, respectively at the same energy cost of 0.039 $/kWh. The results shows that the stearic acid represents a better thermal storage materials use in a solar assisted desiccant air conditioning with thermal storage materials.
