Disclosed is an installation for generating electricity from a heat source, for disconnecting the production of electricity from the source of heat. The main characteristic of such installation is that it includes a thermochemical storage device coupled to a power cycle, the storage device consisting of a reactor in which produces a reversible sorption process and an evaporator and a condenser, at least one of the components of the thermochemical device being coupled mass and/or thermal to at least one element of the power cycle.

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

A method is provided of conducting a thermochemical absorption or desorption reaction between a gas and a solid in the presence of a heat-carrying fluid in a closed enclosure. This method comprises a first step in which, for the pressure prevailing in the reactor, the variation of the mean power of the reaction is determined as a function of the difference which exists between the temperature of the heat-carrying fluid and the equilibrium temperature of the reaction, given by the Clapeyron diagram, for defining an optimum zone in which the reaction takes place with maximum mean power, and a second step in which the reaction takes place, in which a reference temperature is imposed on the heat-carrying fluid such that the reaction takes place in the optimum zone.

Thermochemical method and device for storing and unstoring heat

The invention has for its object an improved method of performing gas-solid reactions. The method is characterized in that there is added expanded graphite of a volumetric mass between 0.001 and 0.02 g/cm.sup.3 to the reactive medium and in such quantity that it constitutes from 1 to 60% of the quantity of reactant solid present in the medium. The method makes it possible to improve the rate of the gas-solid reactions, as well as their stoichiometric characteristics, particularly in the case of reversible reactions.
