<p>A solar heating system incorporates an anti radiation and anit convection system by using a vacuum between the two layers of the heat receiving unit, these two sheets being transparent. To prevent overloading due to atmospheric pressure, the space between is formed as a cellular structure. The insulation behind these panels is directly formed by a heat transfer medium. The two layers may be in the form of two concentric tubes positioned in a chamber formed by a cylindrical/parabolic mirror. The transparent sheets may be coated by a substance to reflect distant infra red rays and transparent to the sun's rays. The mirror is made up of a flat reflective sheet deformed by heat returned inside a guide frame.</p> |
