Optimization of porous reactive media for solid sorption heat pumps.

Author(s) : MAURAN S., COUDEVYLLE O., LU H. B.

Summary

An optimal implementation of the porous reactive media in a solid-gas reactor can be achieved by using a simple model based on simultaneous heat and mass transfers with chemical reaction. The main criterion the authors want to maximize is the heat power per unit mass or per unit volume of the porous media. The use of a chemically inert binder (expanded natural graphite) mixed with the reactive salt leads to a consolidated medium with very high transfer coefficients. The proposed model which takes into account these coefficients, is based on the hypothesis that there are two sharp reactive fronts in the bed. The propagation of these fronts depends only on the coupled heat and mass flows assumed to be at steady-state between two successive reaction rates X. The influence of other parameters can also be estimated.
