Abstract
The research in this paper focuses on the theoretical modeling and optimization of a solar absorption chiller system with a latent heat thermal storage using phase change material (PCM). At first for modeling the absorption chiller cycle, we use the thermodynamic principles. After that with considering the technical limitations we change this model to a standard mathematical planning model by using exergy analyses. At the second step, the mathematical model will be optimized by a genetic algorithm which is inspired by nature. The optimized parameters of cycle will be calculated accurately by doing this step. These parameters consists of the temperature of essential parts i.e. generator, evaporator, absorber, and condenser. Designing a storage system is necessary for resolving the important problem of sun systems which is not absorbing the light of sun at night. So that in the final step, a cylindrical system for storage of energy sun by using storage technique of thermal energy and PCM is designed. This system is analyzed by the enthalpy and Finite Volume Method which their parameters are, dimensions and type of the PCM.
