Enhancing natural ventilation in buildings with double-pass inclined solar chimneys: a sustainable solution

Double-pass inclined solar chimneys are innovative structures designed to harness solar energy for natural ventilation in habitats. Unlike traditional chimneys, which rely solely on the buoyancy of warm air for ventilation, double-pass inclined solar chimneys incorporate solar heat to enhance airflow. These chimneys consist of two passageways: an outer transparent cover and an inner absorber plate. The transparent cover allows sunlight to penetrate and heat the absorber plate, which in turn heats the air within the chimney. As the air warms, it rises due to buoyancy, creating a draft that draws cooler air from the habitat below. This process creates a continuous airflow within the chimney, facilitating natural ventilation. The inclined design of these chimneys maximizes solar exposure throughout the day, optimizing heat absorption and airflow. Additionally, the double-pass conFigureuration enhances thermal efficiency by trapping and utilizing solar heat effectively. By harnessing renewable solar energy, double-pass inclined solar chimneys offer a sustainable solution for ventilating habitats, reducing reliance on mechanical ventilation systems and lowering energy consumption.They provide a cost-effective and eco-friendly alternative for maintaining indoor air quality and comfort in various living spaces.
