Resumen de Optimización de parámetros de un concentrador solar troncocónico
This paper deals with optimizing the design parameters of a truncated cone type hub to capture, transfer and diffusion sunlight, so that reflections of light and increase focus on the walls of the cone and subsequently inside the tube project to the interior of any construction. As an initial parameter think the length of the roof opening of a dome active section of the mark Ciralight square through which the sun's rays fall on a vertical.
Considering the length and diameter greater openness (b) and a concentration factor (FC) of 2.46, was used Excel Solver tool for calculating the optimal key dimensions: the angle of generating (á), height of the cone (h ) And smaller diameter (a), for which it achieves a desired concentration. In addition, it is calculation and design hub truncated cone graphically in Mechanical Desktop 6 Power Pack, from a cone unit according to active dome above. Finally, we built 1:100 scale model to measure the illuminance under conditions of open skies and controlled, using temperature sensor and photodetectors with ranges from 0 to 130 KLX, finding a FC of 1.78 opencast and 1, 89 with a halogen lamp under controlled condition.
