Simulation, Design and Construction of a Polar Parabolic Cylinder Collector (CCPP)

Federico Cervini

Abstract: The objective of this work is to verify the efficiency of a polar parabolic cylindrical collector (CCPP). Latitude-oriented systems differ from traditional ones in that, in polar tracking, the axis of rotation of the collector is tilted to match the latitude of the site. The thermal transfer of these elements generates a linear focus through which a fluid circulates for the generation of electrical energy or process heat. For this, different softwares have been used; to simulate the incidence of the different angles of solar rays, we have considered the ZEMAX-EE, while the Rhinoceros 7 was used to design the geometric configuration and the collecting surfaces. The location chosen was the Optics, Calibration and Testing Laboratory of the Astronomical Observatory of La Plata, at 34?54'28" South Latitude, 57?55'54" West Longitude. Geo positioned by GPS by the Department of Surveying of the Faculty of Engineering-UNLP. The results obtained and contrasted with theoretical calculations present promising evidence for the construction of medium temperature solar fields.
