THERMAL BARRIER AND INNER HEAT-STORAGE ELEMENT

The invention relates to thermal management aimed at maintaining the temperature inside a space. The proposed assembly includes the space and a device arranged around same, placed in an outdoor environment exposed to a non-constant temperature and including at least one thermally insulating element inserted between the inner space and the outdoor environment and, from the inside towards the outside: an inner heat-storage element made of PCM material and an outer thermal barrier containing several PCMs. The invention also includes a cooling unit for provisionally providing, in the inner space, a charge fluid, at least at a temperature that is different from those of the temperature to be maintained, in heat transfer with the PCM of the inner element, so as to store thermal energy.
