Device for producing by chemical reaction cold and/or heat, comprising two reactors (10; 12) containing each an associated salt (S1; S2) susceptible of reacting chemically with a gas and dispersed into a porous support, a housing (16) intended to receive the gas from the reactors (10, 12) and a housing (18) intended to deliver the gas to the reactors. According to the invention, the reactors (10; 12) are arranged in direct contact and in such a way that the heat transfer between each other takes place only by conduction. A process for implementing the chemical reactions between at least one salt and one gas within such a device to produce cold and/or heat is also disclosed.

Dispositif pour produire du froid et/ou de la chaleur par réaction chimique comprenant deux réacteurs (10; 12) renfermant chacun un sel associé (S1; S2) susceptible de réagir chimiquement avec un gaz, et dispersé dans un support poreux, une enceinte (16) destinée à recevoir le gaz des réacteurs (10; 12) et une enceinte (18) destinée à délivrer le gaz aux réacteurs. Selon l'invention, les réacteurs (10; 12) sont disposés en contact direct et sont agencés afin que le transfert de chaleur entre eux se fasse uniquement par conduction. Un procédé de mise en oeuvre de réactions chimiques entre au moins un sel et un gaz, au sein d'un tel dispositif, pour produire du froid et/ou de la chaleur est également décrit.
