Thermochemical system with housing made of composite material

Abstract

The present invention relates to a thermochemical system comprising a reactor (1), or storage enclosure for reactants in a solid state capable of absorbing gases, reactants (2) and gas such that: when reactants and gas When both exist, the reactant and the gas are the objects of a chemical reaction that has the effect of absorbing the gas through the reactant (2), and the reactant and the gas are the objects of a reverse chemical reaction that uses When the reactant has absorbed gas, the gas absorbed by the reactant is desorbed under the action of the heating element (19) applied to the reactant. The thermochemical system is characterized in that the reactor (1) consists of an outer shell (9) made of composite material which surrounds a sealed inner shell (8) containing the reactants, the heating elements (19) are arranged in between the two housings (8, 9).

Description

technical field [0001] The present invention relates to the improvement of thermochemical systems for use in particular in refrigeration and / or heating installations and in storage systems for storing gases in salt form. Background technique [0002] Systems are known which exploit the properties of reversible and strongly exothermic thermochemical reactions during which the reactants, such as salts and especially calcium chloride or barium chloride, absorb suitable Gases, such as especially ammonia. The reversibility of this reaction allows, once the reaction is complete, to recover the initial gas by heating the salt so that the cycle can be repeated. [0003] This property is exploited in refrigeration systems where a thermochemical system is in controlled communication with a storage vessel containing a gas in liquid phase. When the two shells are connected, the liquid gas contained in the storage container evaporates, which absorbs a certain amount of heat, causing th...

Problems solved by technology

[0006] This type of construction has several disadvantages

The first disadvantage is that only large weights of reactors are allowed, which makes the use of these techniques uncompetitive in fields requiring instrument portability

[0007] In addition, these reactors are made of expensive materials, which for implementation require both good technical skills and specialized hardware used by specialists, which significantly increases the cost burden of the system

[0008] Finally, in such reactors, if it is desired to ensure heating from the periphery of such reactors, it is limited to the use of an external heating sleeve

Such arrangements are not satisfactory for use insofar as the external heating sleeve is exposed to various sources of external aggression that can damage the reactor while in use

Furthermore, the arrangement of the heating elements and the reactants inside the reactor has the disadvantage of risking damage during arrangement or simply during use
