Eficiencia de estrategias de enfriamiento pasivo en clima cálido seco Luis Carlos Herrera Sosa Universidad Autónoma de Ciudad Juárez (México)

Abstract

Este documento presenta los resultados de una evaluación de la eficiencia de enfriamiento que se alcanza con la aplicación en techos estanque de seis técnicas de enfriamiento pasivo en clima cálido seco. El procedimiento consistió en monitorear en campo, durante el verano de 2012, módulos experimentales con las técnicas pasivas de enfriamiento: evaporativo indirecto (EEI), protección solar (PS) y enfriamiento radiativo nocturno (ERN), apoyadas con aislamiento térmico (AT) y masa térmica (MT). El módulo experimental se comparó con un módulo de control de iguales características constructivas, dimensiones y orientación. Con los resultados obtenidos en campo se calculó el potencial de enfriamiento medio de cada una de las técnicas pasivas aplicadas para determinar su eficiencia de enfriamiento (EF). Los resultados indicaron que todas las técnicas de enfriamiento pasivo aplicadas tienen capacidad de enfriamiento. La técnica pasiva con mayor potencial de enfriamiento medio fue la EEI+AT+ERN con 822.89 Wh/ m2día, le sigue la EEI+PS con 764.19 Wh/m2día y la EEI+AT+ERN+MT con 532.78 Wh/m2día

This paper presents the results of an evaluation done on the cooling efficiency that could be reached with the use of six passive cooling techniques performed on roof tanks in hot dry weather. The procedure consisted in monitoring at field, during summer 2012, experimental units with the passive cooling techniques: Indirect Evaporative Cooling (IEC), Solar Protection (SP), Night Radiative Cooling (NRC), Thermal Insulation (TI), and Thermal Mass (TM). The experimental unit was compared to a control unit built with the same characteristics, dimensions, and position. With the results obtained at field, there was a calculation of the average cooling potential in each of the applied passive techniques, in order to determine the cooling efficiency (CE). The passive technique with the highest cooling potential average was IEC+TI+NRC with 822.89 Wh/m2day; and those that followed it were IEC+SP with 764.19 Wh/m2day, and IEC+TI+NRC+TM with 532.78 Wh/m2day
