Abstract

Features of a photovoltaic and thermodynamic solar energy conversion were described. The heat transfer fluid type, its temperature and dynamic regime ensures efficiency of a thermodynamic solar energy systems. The 1D mathematical model and numerical algorithm were created for analysis of the thermo-fluid parameters of the flat solar collectors. General recommendations for choose of the heat transfer fluids in the flat solar collectors were presented. In the created 3D mathematical model of the heat exchange in the parabolic trough solar energy systems was taken into account the rheological lаw for the heat transfer fluid. The heat transfer fluid temperature and its dependence from geometric and thermodynamic parameters were obtained after numerical modeling.
