Multifunctional construction elements, prefabricated for external walls and roofs, with the intention to recover renewable energies and to replace fossil energies

摘要

A prefabricated structure consists of a outer metal panel with saw-tooth corrugations to trap solar radiation and an inner insulation panel (5) of polymer foam at least 10 cm thick or fire-resistant mineral wool. The prefabricated structure consists of a outer metal panel with saw-tooth corrugations to trap solar radiation and an inner insulation panel (5) of polymer foam at least 10 cm thick or fire-resistant mineral wool. Between the two panels there are four shutters (6, 7, 8, 9) and a fan to create an air flow, while heat trapped by the corrugated metal panel is transmitted to a fluid such as brine (11) and circulated to a storage tank (AC) through valves (V6, V7). The structure can be used to heat a building in cold weather and keep it cool during the summer.
