RESUMEN: En este artículo se muestra el desarrollo local de un prototipo de concentrador cilindro parabólico y los resultados experimentales de los primeros ensayos que permiten definir la eficiencia del colector y la energía térmica capaz de abastecer. El concentrador está construido principalmente con caño estructural. Esta estructura sostiene una chapa de aluminio de alta reflectancia. Como receptor se utiliza un tubo de vidrio evacuado, del mismo que se utiliza en los colectores ¨Chinos¨. El fluido caloportador (agua) circula por un serpentín de cobre, ubicado en interior del receptor. Como caso práctico se analiza la viabilidad de uso del dispositivo diseñado para la aplicación en la industria textil, en particular en una hilandería de la región, que utiliza agua caliente a diferentes temperaturas, en distintas etapas de la fabricación de tejidos. Para ello con los datos de consumo real, y los resultados experimentales del presente prototipo, se dimensiona el campo de colectores necesario para cubrir las necesidades de la fábrica. Se realiza un análisis comparativo con la posible instalación de un sistema del tipo de heat pipe para la misma fábrica
ABSTRACT: This article shows the local development of a cylindrical parabolic concentrator prototype and the experimental results that allows defining the efficiency of the collector and the thermal energy capable of supplying it. The concentrator is mainly built with structural pipe. This structure supports a high reflectance aluminum sheet. An evacuated glass tube is used as the receiver, the same one used in the “Chinese” collectors. The heat transfer fluid (water) circulates through a copper coil, located inside the receiver. As a practical case, the feasibility of using the device designed for application in the textile industry is analyzed, particularly in a textile factory which uses hot water at different temperatures, at different stages of fabric manufacturing. For this, with the actual consumption data, and the experimental results of the present prototype, the necessary collector field is dimensioned to cover the needs of the factory. A comparative analysis is carried out with the possible installation of a heat pipe type system for the same factory.
