Wall for radiation absorption and method for absorbing radiations and transferring thermal energy in solar walls

摘要

Wall for solar radiation absorption comprising an external plate (2), a first insulation layer (3) disposed behind the external plate (2), the external plate 2 and the first layer (3) permitting transmission of solar radiations, an absorber element (4) disposed behind the insulation layer (3), a massive wall section (10) arranged at a distance from the absorber element (4), a second insulation layer (8) disposed between the massive wall section (10) and the absorber element (4) such that an intermediate cavity (5) is provided between the second insulation layer (8) and the absorber element (4), a heat transporting fluid for transferring heat to the massive wall section (10), the heat transporting fluid passing through the intermediate cavity (5) and through the massive wall section (10), and passage means (6,14) permitting fluid communication between the intermediate cavity (5) and the massive wall section (10).
