Résumé

The paper presents a numerical analysis of the performance of a waste heat adsorption cooling system associated with the coupled heat and mass transfer mechanisms in the adsorbent. A new three-dimensional non-equilibrium model is developed and used to investigate and optimize the simultaneous transport of heat and mass in the waste heat adsorber. It is found that the performance of the system can be seriously deteriorated by poorer mass transfers in the adsorbent if its permeability is smaller than a critical value. On the other hand, for systems with short cycle times, the internal mass transfer resistance can be a significant limiting factor as well.
