dc.descriptionEste trabajo presenta una propuesta de evaluación de la demanda de refrigeración y de la capacidad de refrigeración pasiva por ventilación natural en viviendas sociales. La propuesta se fundamenta en la EN ISO 13790:2008 que utiliza una metodología casi estacionaria de cálculo. Se evalúa una vivienda con ventanas de doble batiente en las dos fachadas, en las diferentes orientaciones N-S, E-O, NO-SE y NE-SO. Se suponen dos posibles caracterizaciones del interior: poco conectado y muy conectado. Los emplazamientos considerados presentan una variedad climática importante, desde los desiertos del norte hasta los climas con variabilidad estacional más marcada del centro- sur del País. Las ciudades consideradas en el estudio son: Arica, Iquique, Antofagasta, La Serena, Valparaíso, Concepción, Valdivia y Puerto Montt. Los resultados muestran la presencia de demanda de refrigeración en la mayoría de los emplazamientos analizados y una capacidad de evacuar el calor por ventilación natural media variable entre el 20% y el 80% de esta demanda, demostrando la importancia de la utilización de las brisas para la refrigeración de edificio y ciudades del País. es-ES
dc.descriptionThis article presents a proposal to evaluate cooling demand and passive cooling capacity using natural ventilation in social housing. The proposal is founded on EN ISO 13790:2008, which uses a semi- dynamic calculation method. The dwellings evaluated have double casement windows in the two main facades, which are oriented N-S, E-W, NW-SE and NE-SW. Two possible internal distributions were tested: poorly-connected and well-connected. The locations evaluated have a variety of climates: from the northern deserts to the weather of central and southern Chile with more defined seasonal variability. The cities included in the study are: Arica, Iquique, Antofagasta, La Serena, Valparaíso, Concepción, Valdivia and Puerto Montt. The results show that cooling demand is present in the majority of the locations analyzed and the average capacity for heat evacuation by natural ventilation is between 20% and 80% of this demand, thereby demonstrating the usefulness of breezes for building and city cooling in Chile. en-US
