Resumen
En el presente trabajo se realiza una comparación de dos métodos de obtención de los grados-día vs los grados-día reales: el desarrollado por investigadores del Centro de Estudios Energéticos y Tecnologías Ambientales y el realizado por Schoenau y Kehrig. Esta comparación se efectúa para validar la metodología de cálculo del primer método con el objetivo de obtener, mediante su uso, un Año Típico-grados-día para la ciudad de Santa Clara. Se utilizan datos aportados por el Instituto de Meteorología para dicha ciudad. Con la utilización del Excel se evaluaron los errores introducidos por ambos métodos, con respecto a los grados-día reales, mediante el uso de la Media del Error y la Raíz del Error Cuadrático Medio. La comparación se realiza para los meses de verano e invierno por ser los meses más significativos del año.
In the present work a comparison of two methods of obtaining degrees-day vs through degrees-day is made: the one developed by researchers of the Center of Energy Studies and Environmental Technologies and the one realized by Schoenau and Kehrig. This comparison is made to validate the methodology of calculation of the first method with the objective of obtaining, through its use, a Typical Year-degrees-day for the city of Santa Clara. Data provided by the Institute of Meteorology for that city are used. With the use of Excel, the errors introduced by both methods, with respect to the actual degree-days, were evaluated using the Mean of Error and the Root of the Mean Squared Error. The comparison is made for the summer and winter months for being the most significant months of the year.
