El consumo energético asociado al sector de la industria representa el 38 % de la demanda de energía a nivel global, siendo un aspecto importante que marca el desarrollo de un país. En este sentido, es sumamente importante diversificar las distintas fuentes de energía e incorporar el uso de fuentes renovables de energía, como la solar, no solamente con la idea de asegurar el suministro energético, sino también considerando como elementos que permitan la reducción de las emisiones generadas por el uso de combustibles fósiles. El presente trabajo aborda las principales tecnologías de colectores solares que pueden ser incorporadas a distintos tipos de industrias, basado en experiencias e investigaciones en otros países. Sobre la base de esta revisión, se ha visto que una buena parte de las industrias a nivel mundial requieren temperaturas en sus procesos hasta los 250 °C, lo que hace idóneo el uso de esta tecnología. En función de cada industria, se podrán usar colectores solares de placa plana, de tubos de vacío, del tipo Fresnel o cilindro parabólicos. Por último, se detallan los ahorros asociados a algunas instalaciones y se abordan los desafíos relacionados con este sector.

“…The focusing of solar radiation in CPC directly depends on the acceptance angle and the design parameters such as location, CPC length, CPC height, size, absorber shape, and aperture width determining CPC's efficiency. The CPC's design parameters have altered based on the application, that is, electrical or thermal 6 . When using the CPC, a large amount of solar radiation is collected and sends to the solar collector, at which the solar collector provides the obtained ratios to working fluids.…”

The compound parabolic collector (CPC) with pulsating heat pipe (PHP) is developed for enhance the heat transfer rate, thermal efficiency and heat losses, and so forth. and working fluid plays a major role in this process. The thermal resistance, temperature, and thermal efficiency have been experimented with under different conditions, and heating periods were analyzed. In this, cobalt oxide (Co3O4) and graphene oxide (GO) added distilled water (DW) is used as the working fluid in the filing ratio of 50%. Bald eagle search optimization (BES) algorithm is used for optimizing the experimented values, and the better‐optimized values are used for hybrid BES based deep belief network (DBN) prediction. The maximum temperature obtained for experiment and optimization is 65 and 65.16161°C. 59% of thermal efficiency was obtained as maximum for experimentation, and 59.1542% of thermal efficiency was obtained as maximum for optimization. The maximum thermal resistance obtained for experimentation and optimization is 0.08 and 0.06938°C/W. In this, optimized outputs performed well than the experimental values. Besides, the hybrid DBN based BES algorithm is performed based on the optimized performances to predict the temperature, thermal efficiency and thermal resistance. Further, predicted outcomes are compared with the non‐hybrid neural networks such as DBN, CNN and ANN. DBN‐BES depicts low error values than the non‐hybrid neural networks. Overall, the proposed hybrid solar collector model and the hybrid nanoparticles added water helps to enhance the thermal characteristics with minimum heat loss.
