38 stack ventilation diagram
Cross-flow and Passive Stack Ventilation. Passive stack ventilation (PSV) is the most effective natural ventilation strategy as it uses a combination of cross ventilation, buoyancy (warm air rising) and the venturi (wind passing over the terminals causing suction) effect. external temperatures have a higher variance at night increasing convection. Stack ventilation uses temperature differences to move air. Hot air rises because of its low-pressure characteristics. Bernoulli's principle uses wind speed differences to move air, so it can also fall into the wind-driven ventilation category. It is a general principle of fluid dynamics that the faster air moves, the lower its pressure. Jul 5, 2021 — Stack ventilation can be particularly effective as a means of naturally ventilating tall buildings that include vertical spaces which rise ... Stack ventilation diagram
