THE DETERMINATION OF EXERGY OF OPTICAL RADIATION (LIGHT) - BASIC SOURCE OF RENEWABLE ENERGY

摘要

While approaching the depletion of nonrenewable energy combustible fossils the solar optical radiation (OR) starts to be a lot more important as the greatest renewable primary energy source. Directly the energy of OR is used mainly by means of thermal, photoelectric conversion and photosynthesis of plants. In power engineering the valuation of potential change of primal source energy is carried out on the basis of the quantity of exergy. Method of power engineering conversion of OR exergy by means of well-founded thermal processes is widely used [1,2].
