<p>The device (10) has a variable absorption surface (20) interposed between a transparent wall (12) and an insulating module (14). The surface is exposed to solar radiations (S) through the wall, and has absorbing regions (20A) and reflecting regions (20R). Mobile shutters (22) are arranged with respect to the absorption surface, and has absorbing surfaces (22A) and reflecting surfaces (22R). The shutters move between two positions for changing the absorption regions and/or the reflecting regions along with the absorption surfaces and/or reflecting surfaces exposed to the radiations.</p> |
