摘要:
The present invention relates to a thermochemical system comprising a reactor, or an enclosure for storing a solid reactive material capable of absorbing a gas, the reactive material and the gas being such that, when placed together, a chemical reaction occurs which results in the gas being absorbed by the reactive material, and a reverse chemical reaction occurs, wherein the gas absorbed by the reactive material is desorbed when heating means are applied to said reactive material when the latter has absorbed the gas. Said thermochemical system is characterized in that the reactor consists of an outer housing which is made of a composite material and which contains a sealed inner housing containing the reactive material, the heating means being arranged between the two enclosures.

A thermochemical system having a reactor or a chamber for storing a reactive material capable of absorbing a gas that is taken into the reactor by a diffuser placed along the longitudinal axis of the latter. The reactive material and the gas are such that, when placed in the presence of each other, same are subjected to a reaction causing the reactive material to absorb the gas, and conversely, same are subjected to a reaction for desorbing the gas, absorbed by the reactive material, by heating applied to the latter when it has absorbed gas. The diffuser includes a gas supply mechanism, a mechanism for dispensing the gas into the reactive material, a filtration mechanism, and a heating mechanism. The various mechanisms form a sub-assembly that is attached onto the housing of the reactor by a sealing element.

The invention relates to a thermochemical reactor (1) for a cooling and/or heating apparatus, comprising at least one reagent unit (2) which, by means of chemical combination, can absorb, a gas stream originating from a tank and which, by means of the reverse chemical reaction, cab desorb said gas stream due to a rise in temperature. The reagent unit (2) is disposed in a container (3) comprising walls, of which at least some are equipped with diffuser means (7) for distributing the gas stream. In addition, the reagent unit (2) is of the type that can expand during absorption of the gas stream and retract during desorption of the gas stream, said unit being connected to heating means. Moreover, at least some of the above-mentioned walls consist of mobile walls, which can accompany the longitudinal movement performed by the reagent unit (2), such as to enable successive deformation phenomena.

摘要:
The invention concerns a method for controlling a thermochemical reaction or a solid-gas adsorption being carried out in a reactor (10) containing an active agent capable of reversibly reacting with a gas, the reactor (10) being connected to an evaporator/condenser assembly (14) for the gas by a connection (12) without control valve, the reactor (10) and the evaporator/condenser assembly (14) each provided with means for selectively exchanging calories with their surroundings. The control method consists in: thermally insulating the reactor (10) and the evaporator/condenser assembly (14) from the surroundings; thermally communicating the reactor (10) with its surroundings so that the active agent reacts with the gas, thereby providing cold to the evaporator (14); thermally communicating the evaporator (14) with its surroundings so as to cool it selectively; and selectively insulating the reactor (10) or the evaporator/condenser assembly (14) from their surroundings so as to stop the reaction at one point of the reversible cycle.
