Thermodynamic Analysis and Simulation of the Absorption Refrigeration System

Refrigeration by absorption is gaining more and more importance, especially in applications, where the source of energy used in the generator is renewable. Our work aimed at providing a cooling system adequate to the weather conditions in Tunisia as well as other Euro-Mediterranean regions. Furthermore, this cooling system is at the same time environment-friendly and economical. Heat wastes and solar energy were used as the source of energy in the generator. In this context, we were interested in the thermodynamic analysis of the single-effect absorption refrigeration machine operating with the pair ammonia/water. The modeling and simulation of this machine were carried out by the software Engineering Equation Solver (EES) in order to look for the optimal conditions for the work of this machine and study the effect of various operating parameters on the system efficiency.
