| Sumario: | This article deals with toroidal concentrators of solar radiation. The developed design configurations have been described. The base model is a semi-torus obtained by cutting full torus along the symmetry plane, the inner surface of semi-toroidal surface is of specular type. The inner surface of semi-toroidal surface is of specular type. The semi-circles of the concentrator cross-section are the generatrices of the surfaces. The radiation receiver is mounted in the midsection, and the radiation receiver symmetry point coincides with that of the concentrator. Results of experimental and theoretical studies of their characteristics have been discussed. Various models employing the advantages of toroidal concentrators have been considered. Analysis results of the most preferable radiation receivers have been presented. Layout options of integration of photoelectric plants equipped with toroidal concentrators of solar radiation into buildings and landscape design objects have been described. Physical limitations of application of installations based on concentrators of this type have been defined and substantiated. Methods for evaluating coast-related characteristics of toroidal concentrators depending on values of their output parameters and on those of design have been presented. |
