CAMPO DE LA INVENCiÓN FIELD OF THE INVENTION
La invención se encuadra dentro del sector de la energía solar de concentración, concretamente dentro de la energía solar térmica de media temperatura, y permite un aprovechamiento múltiple de los captadores cilindroparabólicos ampliando su rango de trabajo a temperaturas más reducidas así como el aprovechamiento de la radiación global. Adicionalmente, se podrá plantear un aprovechamiento eléctrico directo a través de la integración de células fotovoltaicas en el propio dispositivo. La aplicación básica que se propone para esta invención es la generación de calor de origen solar en procesos con demandas térmicas en media y baja temperatura en entornos caracterizados por restricciones de espacio a la hora de ubicar los captadores solares. The invention is part of the concentration solar energy sector, specifically in the medium temperature thermal solar energy, and allows multiple use of parabolic trough collectors by extending their working range at lower temperatures as well as the use of radiation global. Additionally, a direct electrical use may be proposed through the integration of photovoltaic cells in the device itself. The basic application proposed for this invention is the generation of heat of solar origin in processes with thermal demands in medium and low temperature in environments characterized by space restrictions when locating solar collectors.
ANTECEDENTES DE LA INVENCiÓN BACKGROUND OF THE INVENTION
Esta invención parte de dos conceptos técnicos bien establecidos en el campo de la energía solar térmica que hasta la fecha se han caracterizado por aplicaciones y sistemas independientes entre sí. El primer concepto es el de concentrador cilindroparabólico, consistente en un reflector conformado de tal manera que Concentra la radiación solar directa sobre un foco lineal ocupado por un receptor tubular convenientemente diseñado para transferir la mayor cantidad posible de flujo térmico sobre un fluido caloportador, normalmente aceite o agua presurizada, y provocar de esta manera en el mismo un incremento de temperatura que le permite actuar como fuente térmica en procesos con temperaturas de operación entre 180 y 400 oc. El segundo concepto es el de captador solar plano, constituido por un conjunto de tubos, normalmente metálicos, acoplados a aletas planas, también metálicas, estando todo el conjunto de tubos y aletas confinado en una carcasa rectangular cuya superficie expuesta a la radiación solar está cubierta por una lámina de vidrio u otra barrera anticonvección transparente, quedando el resto de superficies que constituyen la carcasa aisladas térmicamente del exterior. El fluido de trabajo en este caso es agua o una mezcla de agua y anticongelante, siendo las temperaturas de operación habituales entre 45 y los 90 oc. En el caso de los captadores solares cilindroparabólicos el aprovechamiento de la radiación solar se realiza a partir de la componente directa de la misma (radiación preveniente de la dirección del disco solar), por lo que resulta indispensable para su correcto funcionamiento la incorporación de mecanismos de seguimiento del Sol con el fin de maximizar la concentración de flujo solar sobre el tubo receptor. Los captadores de placa plana aprovechan la radiación solar global (radiación This invention is based on two well-established technical concepts in the field of solar thermal energy that to date have been characterized by applications and systems independent of each other. The first concept is that of a parabolic trough concentrator, consisting of a reflector shaped in such a way that it concentrates direct solar radiation on a linear focus occupied by a tubular receiver conveniently designed to transfer as much heat flow as possible into a heat transfer fluid, usually oil. or pressurized water, and in this way cause an increase in temperature that allows it to act as a thermal source in processes with operating temperatures between 180 and 400 oc. The second concept is that of a flat solar collector, consisting of a set of tubes, usually metallic, coupled to flat fins, also metallic, the entire set of tubes and fins being confined in a rectangular housing whose surface exposed to solar radiation is covered by a sheet of glass or other transparent anti-convection barrier, leaving the rest of the surfaces that constitute the housing thermally insulated from the outside. The working fluid in this case is water or a mixture of water and antifreeze, the usual operating temperatures being between 45 and 90 oc. In the case of parabolic trough solar collectors, the use of solar radiation is made from its direct component (radiation from the direction of the solar disk), so it is essential for its correct operation the incorporation of mechanisms of Sun tracking in order to maximize the concentration of solar flux on the receiving tube. Flat plate collectors take advantage of global solar radiation (radiation
directa no concentrada sobre el plano del captador más radiación difusa) y suelen permanecer fijos con una inclinación y exposición al Sol calculada de acuerdo a la pauta estacional de la demanda térmica a la que deben hacer frente. la configuración y estructura básica de ambas tecnologías se describen en tratados direct not concentrated on the plane of the collector plus diffuse radiation) and usually remain fixed with an inclination and exposure to the Sun calculated according to the seasonal pattern of the thermal demand they must face. the configuration and basic structure of both technologies are described in treaties

DESCRIPCiÓN DE LA INVENCiÓN DESCRIPTION OF THE INVENTION

Dichas lamas rotativas contienen adicionalmente en su interior un circuito hidráulico para la extracción de calor (7). El tubo absorbedor central (3) puede también ser de cristal transparente para facilitar la absorción directa en el caso de uso de nano fluidos como medios de transferencia térmica. El modo concentrador se obtiene a través del alineamiento paralelo al eje de la parábola de las lamas absorbedoras (Figura 1) para permitir la incidencia de la radiación solar directa sobre el reflector y la posterior concentración focal en el absorbedor tubular central a través de un sistema mecánico de seguimiento del Sol. El modo captador plano se obtiene a través del alineamiento transversal de las lamas (Figura 2), de manera que la radiación solar difusa/global se absorbe en dichas lamas, y el calor se transferirá desde las lamas absorbedoras planas al fluido que circula en los tubos insertados en las propias lamas, en el caso de que estas los incluyan, o al fluido en el tubo central a través de una conexión física en forma de T_ la cubierta de vidrio en el plano de apertura (1) actúa como barrera térmic.a al exterior para disminuir las perdidas térmicas. La superficie superior de las lamas rotativas (8) puede ser recubierta con un tratamiento selectivo, y/o celdas fotovoltaicas para permitir modos de generación de energía adicionales del captador.

Said rotary slats additionally contain a hydraulic circuit for heat extraction (7). The central absorber tube (3) can also be made of transparent glass to facilitate direct absorption in the case of using nano fluids as thermal transfer means. The concentrator mode is obtained through the alignment parallel to the axis of the parabola of the absorber slats (Figure 1) to allow the incidence of direct solar radiation on the reflector and the subsequent focal concentration in the central tubular absorber through a system mechanical tracking of the Sun. The flat sensor mode is obtained through the transverse alignment of the slats (Figure 2), so that diffuse / global solar radiation is absorbed in said slats, and heat will be transferred from the flat absorber slats to the fluid that circulates in the tubes inserted in the slats themselves, in case they include them, or to the fluid in the central tube through a physical connection in the form of T_ the glass cover in the opening plane (1 ) acts as a thermal barrier to the outside to reduce thermal losses.
