Abstract


This work is an energy analysis of a simple effect absorption cooling system operating with H2O-LiBr pair in the climatic conditions of Senegal. To achieve this, the energy balance at the level of the various components of the system will be established in order to show the behavior of each component of the system according to the climatic conditions of the study site. To find out if this cooling absorption system is suitable for the Senegalese climate, the effects of the temperature of the absorber and the generator have respectively been seen on the mass flow rates and on the circulation factor. The behavior of the cooling absorption system in the weather conditions of Senegal was predicted using a mathematical model developed with Engineering Equation Solver (EES) software. The simulation results of this present work were compared with those found in the literature. The thermodynamic parameters such as temperature, entropy, enthalpy, mass fraction found at the level of the various components of the system are in agreement with those found by other authors. Similarly, the results obtained show that for better performance of the system, the operating parameters must be optimized taking into account the crystallization limits of lithium bromide. Similarly, modifications must be made to the design of some devices such as the absorber and the generator to better adapt them to local climatic conditions. Beyond the design and modification of the components of the system, it is also necessary to play on the operating conditions for a better functioning of the absorption cooling system in Senegal.
