RESUMEN: En el presente trabajo, se demuestra el truncamiento óptimo de los CPCs empleando la Ley Cosntructal, estableciendo diferentes grupos funcionales que establecen los grados de libertad del sistema. Los grados de libertad involucran los parámetros geométricos que repercuten de manera directa en la potencia térmica que incide sobre el absorbedor (función objetivo). Al realizar la variación de los parámetros geométricos, se identifica el valor óptimo de operación. Posteriormente, se analiza la evolución de los diseños Tolokatsin en los 30 años de existencia, verificando un óptimo desempeño mediante una serie de pruebas experimentales en las que se recabaron mediciones de temperatura e irradiancia, para cuantificar la potencia térmica útil (carga de calentamiento) en el horno solar.
ABSTRACT: In the present work, the optimal truncation of the CPCs is demonstrated using the Cosntructal Law, establishing different functional groups that establish the degrees of freedom of the system. The degrees of freedom involve the geometric parameters that directly affect the thermal power that affects the absorber (objective function). When performing the variation of the geometric parameters, the optimum operating value is identified. Subsequently, the evolution of Tolokatsin designs in the 30 years of existence is analyzed, verifying optimum performance through a series of experimental tests in which temperature and irradiance measurements were collected, to quantify the useful thermal power (heating load) in the solar oven.
