Abstract (en)
The development of a prototype linear solar collector Type Fresnel, has a purpose the use of direct solar heat radiation for water heating and/or steam production, as an alternative to supply conventional water heating systems or steam generators, which consume energy from fossil fuels.
For the development of the system, used the solar radiation of the UTS, located in Bucaramanga, Colombia, is identify the mathematical models to perform the sizing, then materials based on technical specifications and availability in Colombia, in order to perform the assembly and field tests, measuring the ambient and in the collector temperature to determine the efficiency of the model.
It should be noted that, the model presented does not have a control system for flow, temperature, pressure and level, it has no solar tracking of any kind; Its movement was done manually with each reflex. Finally, the model does not have a hydraulic system forced, and has a preheater at the entry of the concentration point.

El desarrollo de un prototipo de colector solar lineal Tipo Fresnel tiene como finalidad el aprovechamiento de la radiación solar directa en calor para el calentamiento de agua y/o la producción de vapor, como alternativa para suplir los sistemas de calentamiento de agua o generadores de vapor convencionales, que consumen energía proveniente de combustibles fósiles.
Para el desarrollo del sistema, se utiliza la radiación solar de las UTS, ubicada en Bucaramanga, Colombia, se identifican los modelos matemáticos para realizar el dimensionamiento, posteriormente se seleccionan materiales basados en especificaciones técnicas y disponibilidad en Colombia, con el fin de realizar el montaje y realizar pruebas en campo, midiendo la temperatura ambiente y en el colector para determinar la eficiencia del modelo.
Cabe resaltar, que el modelo presentado no cuenta con sistema de control de flujo, temperatura, presión y nivel, no tiene seguimiento solar de ningún tipo; el movimiento del mismo se realizó manualmente con cada reflecto. Por último, el modelo no cuenta con sistema hidráulico de tiro forzado, y tiene un precalentador a la entrada del punto de concentración.
