La radiaci\u00f3n infrarroja se menciona con frecuencia en diversos art\u00edculos, sobre todo en referencia a los tubos de calefacci\u00f3n por infrarrojos de fibra de carbono, como una forma de calefacci\u00f3n radiante. \u00bfQu\u00e9 es la calefacci\u00f3n radiante? Hoy voy a dar una explicaci\u00f3n detallada de la radiaci\u00f3n t\u00e9rmica, uno de los tres modos de transferencia de calor.<\/p>\n\n\n\n
La radiaci\u00f3n es un m\u00e9todo de transferencia de energ\u00eda mediante ondas electromagn\u00e9ticas. Los objetos emiten radiaci\u00f3n por diversas razones, y el fen\u00f3meno de emisi\u00f3n de radiaci\u00f3n debido al calor se denomina radiaci\u00f3n t\u00e9rmica. En la naturaleza, todos los objetos emiten continuamente radiaci\u00f3n t\u00e9rmica al espacio circundante, al tiempo que absorben la radiaci\u00f3n t\u00e9rmica emitida por otros objetos. Bajo un esc\u00e1ner de infrarrojos, todos los objetos mostrar\u00e1n alguna indicaci\u00f3n de temperatura o imagen de barrido, excepto un cuerpo negro te\u00f3ricamente puro, que no exhibe radiaci\u00f3n t\u00e9rmica.<\/p>\n\n\n\n
Los procesos naturales de radiaci\u00f3n y absorci\u00f3n dan lugar conjuntamente a la transferencia de calor entre objetos a trav\u00e9s de la radiaci\u00f3n, tambi\u00e9n conocida com\u00fanmente como intercambio de calor por radiaci\u00f3n infrarroja. Cuando un objeto est\u00e1 en equilibrio t\u00e9rmico con su entorno, la transferencia neta de calor por radiaci\u00f3n es nula. Sin embargo, esto no implica una ausencia de intercambio de radiaci\u00f3n en el entorno, sino que la energ\u00eda radiada por los objetos del entorno es igual a la energ\u00eda que absorben, alcanz\u00e1ndose un equilibrio relativo en el que los procesos de radiaci\u00f3n y absorci\u00f3n est\u00e1n continuamente activos.<\/p>\n\n\n\n
A diferencia de la radiaci\u00f3n, los otros dos modos de transferencia de calor, la conducci\u00f3n y la convecci\u00f3n, requieren un medio para la transmisi\u00f3n de energ\u00eda, como materiales s\u00f3lidos, aire, agua u otros gases y l\u00edquidos, incluidas sus mezclas. La radiaci\u00f3n no requiere un medio y puede producirse incluso en el vac\u00edo, lo que la convierte en el m\u00e9todo m\u00e1s eficaz de transferencia de calor en entornos de vac\u00edo. Esta distinci\u00f3n es una caracter\u00edstica fundamental que diferencia la radiaci\u00f3n de la conducci\u00f3n y la convecci\u00f3n. Cuando dos objetos est\u00e1n separados por el vac\u00edo, no pueden producirse ni conducci\u00f3n ni convecci\u00f3n, y s\u00f3lo es posible la transferencia de calor por radiaci\u00f3n.<\/p>\n\n\n\n
La energ\u00eda transportada por la luz solar se transmite a trav\u00e9s del vasto vac\u00edo del espacio hasta la Tierra por medio de la radiaci\u00f3n t\u00e9rmica, donde es absorbida y utilizada por todos los seres vivos. Art\u00edculos de uso cotidiano como los termos y las tazas aisladas al vac\u00edo utilizan el principio del aislamiento al vac\u00edo para lograr el aislamiento t\u00e9rmico y la separaci\u00f3n de temperaturas. Otro aspecto \u00fanico de la transferencia de calor por radiaci\u00f3n es que no s\u00f3lo implica la transferencia de energ\u00eda, sino tambi\u00e9n la conversi\u00f3n de formas de energ\u00eda; la energ\u00eda se emite como energ\u00eda radiante y se convierte de nuevo en energ\u00eda t\u00e9rmica al ser absorbida.<\/p>\n\n\n\n
Los experimentos han demostrado que la capacidad de radiaci\u00f3n de un objeto depende de la temperatura y que, a la misma temperatura, los distintos objetos presentan capacidades de radiaci\u00f3n y absorci\u00f3n diferentes. Un material ideal conocido como cuerpo negro puede absorber toda la energ\u00eda radiada, aunque tales materiales son poco frecuentes en la vida real. Esta variabilidad en la absorci\u00f3n de la radiaci\u00f3n infrarroja por los distintos materiales es la raz\u00f3n por la que se seleccionan distintos tipos de tubos calefactores en funci\u00f3n del producto cuando se utilizan tubos calefactores de fibra de carbono para secar materiales.<\/p>\n\n\n\n
