The present invention relates to an enclosure which is refrigerated and kept at a predetermined set temperature (Te), containing the evaporator (7) of a refrigerating unit (5). Said enclosure is characterised in that: same comprises a thermochemical system (9) the circuit of which is separate from that of the refrigerating unit and which includes a reactor (1) containing a reactive product capable of absorbing a gas, a condenser and an evaporator arranged in said enclosure (3), the reactive product and the gas being such as to be the subject, when placed in the presence of one another, of a reaction which has the effect of the gas being absorbed by the reactive product and, conversely, to be the subject of a desorption reaction of the gas absorbed by the reactive product when heat is applied thereto once the gas has been absorbed, the thermochemical system having two operating phases, namely a cold-production phase and a regeneration phase, said system comprising measurement (14) and control (19) means which only enable the thermochemical system (9) to enter the regeneration phase if the temperature of the condenser (17) thereof is below a predetermined threshold temperature (Ts).
Enclosure refrigerated and maintained at a specific desired temperature Te containing the evaporator of a refrigeration unit, characterized in that:
Method of cooling an enclosure and maintaining it at a specific desired temperature by means of a refrigeration unit and a thermochemical system, the circuits of which are independent of each other, of the type having a reactor containing a reactive product capable of absorbing a gas, a condenser and an evaporator disposed inside said enclosure, the reactive product and the gas being such that when they are placed in each other's presence, a reaction is produced resulting in the absorption of the gas by the reactive product, and in reverse, a reaction is produced of desorption of the gas absorbed by the reactive product under the effect of heat applied thereto when it has absorbed the gas, the thermochemical system (9) having two phases of operation, i.e. a cold production phase and a regeneration phase, characterized in that entry of the thermochemical system into the regeneration phase is allowed on the condition that the temperature of the condenser of said system is below a specific threshold temperature.
