Thermochemical system having a housing made of a composite material

Abstract

The present invention relates to a thermochemical system comprising a reactor (1), or an enclosure for storing a solid reactive material capable of absorbing a gas, the reactive material (2) and the gas being such that, when placed together, a chemical reaction occurs which results in the gas being absorbed by the reactive material (2), and a reverse chemical reaction occurs, wherein the gas absorbed by the reactive material is desorbed when heating means (17) are applied to said reactive material when the latter has absorbed the gas. Said thermochemical system is characterized in that the reactor (1) consists of an outer housing (9) which is made of a composite material and which contains a sealed inner housing (8) containing the reactive material, the heating means (17) being arranged between the two enclosures (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
