External modular device for autonomous regulation of the temperature of an enclosure

Modular device for autonomous regulation of the temperature to a specific set value, capable of being mounted on at least one storage enclosure, characterized in that it comprises a housing that contains a thermochemical system comprising a tank, possibly forming an evaporator and containing a liquefied gas capable, after evaporation, of being combined with a reactive product contained in a reactor, according to an exothermic thermochemical reaction, the reaction product obtained being capable of being regenerated by heating while releasing said gas according to a reverse thermochemical reaction, the reactor and the evaporator of the thermochemical system respectively constituting means of heating and means of cooling said enclosure, and being respectively disposed in a reactor compartment and an evaporator compartment made in said housing, and in that said device further comprises switching means disposed in said housing and capable of:

• placing the reactor compartment in communication with only the storage enclosure in order to heat the latter, and at the same time, placing the evaporator compartment in communication with the exterior of the device,
• placing the evaporator compartment in communication with only the storage enclosure in order to cool the latter, and at the same time, placing the reactor compartment in communication with the exterior of the device.
