Abstract
El uso de la energía solar se ha incrementado en los últimos años, cubriendo demandas energéticas en distintas áreas donde el acceso al sistema interconectado se ve dificultado. La coincidencia de la demanda de producción de frío y la alta disponibilidad de radiación solar en verano hace a la energía solar particularmente atractiva para sistemas de refrigeración, es por esto que estudiaremos la eficiencia energética de una cámara de frío solar autónoma, adaptada para llegar a lugares de difícil acceso para ser utilizada en la conservación y almacenamiento de productos, dando la posibilidad de cumplir con una la cadena de frío después de su recolección. Para esto fue necesario crear un sistema de adquisición de datos a través de sensores que pudieran procesar, medir y almacenar datos de temperatura y potencia en la cámara, para luego recolectarla e interpretar los datos medidos y evaluar el desempeño energético de la cámara en condiciones ambientales locales. Los resultados obtenidos nos permitieron evaluar los límites de operación de la cámara.
The use of solar energy has increased in recent years, covering energy demands in different areas where access to the interconnected system is difficult. The coincidence of the demand for cooling production and the high availability of solar radiation in summer makes solar energy particularly attractive as an energy source for cooling systems, this is why we will study the energy efficiency of an autonomous solar cold room, adapted to reach places of difficult access to be used in the preservation and storage of products, giving the possibility to comply with the cold chain after harvesting. For this it was necessary to create a data acquisition system through sensors that could process, measure and store temperature and power data in the chamber, and then collect and interpret the measured data to evaluate the energy performance of the chamber under local environmental conditions. The results obtained allowed us to evaluate the operating limits of the chamber.
