Active composite and its use as reaction medium

Device for producing cold and/or heat by solid-gas reaction, intended to be used, for example, for air conditioning, including reactor chambers, each chamber being intended to contain a reagent formed from a mixture of a salt and an expanded product which is a good thermal conductor, the reagent being able to react through absorption with a gas according to an exothermic reaction, the device including moreover, a passage for a fluid to be cooled and a passage for a fluid to be heated. According to the invention, the device includes reactor chambers connected together pairwise, the transfer of heat between the reactor chambers and with the fluid being afforded by heat pipes of the gravitational type.

Devices for producing cold and/or heat by solid-gas reaction managed by

Device for producing cold and/or heat by a solid gas reaction comprising a first and a second reactor each of which contains a salt capable of reacting by absorption with a gas by an exothermic reaction, the first reactor being in communication in a first operating stage with an enclosure intended to retain the gas, the second reactor being in communication, in the first operating stage, with an enclosure intended to release the gas, according to the invention, each reactor comprises a different salt. A device comprising four reactors provided with three different salts is also described.
