Abstract
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).
