Contribution à l'étude des machines à froid à sorption solide par bi-régénération en fonctionnement semi-continu

Abstract : The report of thesis relates to the theoretical and experimental study of the semi - continuous operation of a bi - regeneration solid sorption machine. The theoretical study relates to the thermodynamic analysis methods, (entropic, exergetic and optimization) of the exchanges and degradations of energy in the components and in the system, and to the modelling of the operation of the machine for the mastery of the switchings and the recovery of energy in generators . The characterization of the calorific transfers and the influence of the total and contact thermal conductances within the porous medium of the generator were examined.The experimental part relates to the development of the new generators, the influence of the semi-continuous operation parameters, mass and calorific loads, on the performances of the system and the tests in condensation of the refrigerant. This allowed the determination of the criteria of switchings and reduction the time of phases in the operation cycle of the system.
