A reagent (26) combines exothermically with a cold refrigerating fluid exiting a refrigerating evaporator during a refrigeration cycle, then releases the refrigerating fluid endothermically once it has been heated to a sufficiently high temperature by means of a heating element (17) during a regeneration cycle during which the released refrigerating fluid condenses in a pressurized tank. The reagent is confined inside stainless steel walls (29, 31, 34) which prevent it from swelling. These walls include perforated tubes (34) lining channels (32) in which the mass exchanges take place during the combining and separating reactions. The heating element (17) is fitted in a central cavity (46). An air flow (54), which is interrupted during regeneration, evacuates the heat of the combining reaction by means of fins (56). The invention prevents the block of reagent from distorting and becoming progressively inoperative over repeated cycles.

A chemical 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, 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.
