Chemical reactor, refrigerating machine and container provided therewith and reagent cartridge therefor

A refrigerating machine, including in a closed circuit, a high pressure reservoir, a pressure reduction device and a chemical reactor for a refrigerating machine having a supply of reagent intended to absorb by chemical combination a gaseous flow coming from an evaporator and to desorb this flow by reverse chemical reaction under the effect of a rise in temperature, the reagent being confined between confining faces at least some of which are permeable to mass exchanges, characterized in that the reagent is formed as at least one solid block of reagent prior to its installation in the reactor between said confining faces so that said block is capable of volume variations as a function of the quantity of gas which it has absorbed, and in that the confining faces are part of confining walls configured to exert an initial light clamping force upon said at least one block which is capable of providing the block with shape stability for resisting said volume variations.

A reagent cartridge, in particular for being part of a reactor for a refrigerating machine including a supply of reagent intended to absorb by chemical combination a gaseous flow coming from an evaporator and to desorb this flow by reverse chemical reaction under the effect of a rise in temperature comprising,

• said reagent being formed as at least one solid block prior to its installation in the reactor, said at least one block being configured for confinement between confining faces at least some of which are permeable to mass exchanges, said at least one block being capable of volume variations as a function of the quantity of gas which it has absorbed and in that the confining faces are part of confining walls configured to exert an initial light clamping force upon said at least one block which is capable of providing the block with shape stability which resists said volume variations;
• and
• said at least one block of reagent being enclosed in a fluid-tight casing, said block having cavities emerging through the fluid-tight casing and closed in a fluid-tight manner by temporary obturations.
