Exergy of direct solar radiation

Konstantin Ludanov

Abstract: 

The article provides an exergy analysis of the concentration of solar radiation. For the first time, the flux of solar radiation is characterized by its own temperature (radiation), and its exergy is determined within the framework of the canonical Carnot cycle. Based on a new treatment of the temperature of the radiant heat flux, an analytical expression is obtained for the radiation temperature of the solar radiation flux, both for direct solar radiation and for diffuse radiation. The dependence of the density of direct solar radiation on the "mass of the atmosphere" is found. These formulas allow us to calculate the radiation temperature of the solar radiation flux and the exergy flux density on the Earth's surface and in the focus of the concentrator's mirror.
