Importance of emissivity
Witryna1 sie 2003 · Emissivity is an expression used to characterise the optical properties of materials in sense of the amount of energy emitted in comparison with an ideal black body [3]. Values for emissivity ( ε) can be between 0 (perfect reflector—mirror) and 1 (perfect emitter—black body). As a result, emissivity plays an important role in … WitrynaRecently, low-emissivity paint has gained more importance than commercial paints. Low emissivity (Low-E) Paint also termed as a coating for radiation control, in which the emissivity of radiations ...
