Claim:
1. A system comprising an insulated enclosure having a temperature, said temperature having to be maintained at a desired temperature value T e , said system comprising: a refrigeration unit which comprises a refrigeration circuit and a refrigeration-unit evaporator; and a thermochemical system having a thermochemical circuit independent of said refrigeration circuit, said thermochemical system comprising a reactor containing a reactive product capable of absorbing a gas, a condenser and an evaporator disposed in said enclosure, said condenser having a condenser temperature, said reactive product and said gas being such that, when placed together, said gas and said reactive product are the object of a reaction resulting in the absorption of said gas by said reactive product, and in the reverse, said gas and said reactive product are the object of a gas desorption of said gas under the effect of heating applied to said reactive product once said reactive product has absorbed said gas wherein said refrigeration-unit evaporator is disposed inside said insulated enclosure said evaporator is disposed inside said insulated enclosure and said system comprising a temperature sensor for measuring the temperature T c of said condenser and a microcontroller associated with said temperature sensor for allowing said gas desorption only on the condition that the value of said condenser temperature is below a given condenser threshold temperature and also for blocking the changeover of said thermochemical system from said gas desorption to said gas absorption as long as the operation of said refrigeration unit is not interrupted.
