Résumé
The depletion and high cost of fossil energy sources are the main cause leading to the energy transition. Industrial processes are increasingly using renewable resources, and adapting the zero-waste policy, to improve their energy efficiency. This study investigates the thermodynamic performance of the diffusion absorption refrigeration (DAR) system, equipped with an ejector and a compressor. The system operates using the residual heat of the gases exiting the cement kiln chimneys, recovered from the high-performance heat exchangers. The system is modelled and optimized using the M2EP analysis method (mass, energy, exergy and performance) and the particle swarm optimization algorithm. The refrigeration machine generates cold by evaporating the strong solution of the H2O+NH3 mixture. Hydrogen circulates in the diffusion-absorption-compressor-ejector refrigerator circuit, facilitating the exchange between the evaporator and the absorber. A compressor and an ejector, placed between the evaporator and the absorber, increase the system pressure, therefore the coefficient of performance of the refrigeration machine. MATLAB and Excel software were used to solve the system of equations. The sensitivity of the model to variations in concentration, temperature and pressure was studied and analyzed. The results of this article serve as a decision-making tool for the installation of such a refrigeration system in a cement plant, to be able to valorize the gaseous waste generated.
