Abstract: A device for storing heat energy/cold energy, including a container having a wall (102) with a first interface (110) suitable for letting a fluid into the device (100) and a second interface (111) suitable for letting the fluid out of the device (100), with a plurality of storage elements (104) being arranged in the container and configured to store heat energy/cold energy supplied by the fluid. The container has at least one perforated internal wall (105) with openings of dimensions smaller than the dimensions of the storage elements (104) and defining a first compartment (131) and at least one second compartment (132) in the container, with the plurality of storage elements (104) being distributed in the first compartment (131) and in said at least one second compartment (132).

Abstract: A heat-generating assembly (1) includes at least one airflow generation device, air supply which is fluidically connected to the airflow generation device, and at least three heating devices, each having an air inlet connected to the air supply, and a reheated air outlet. The airflow generation device and the heating devices are controlled in that the heating devices are distributed along at least one perimeter line, and in that each perimeter line section which contains three adjacent heating devices is curvilinear.
