The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences ...
Some early approaches to the problem were adaptations of the conventional chimney. [1] A hearth constructed by Thomas Jefferson in 1822–1826 at the University of Virginia was equipped with a sand bath and special flues to vent toxic gases. [2] The draft of a chimney was also used by Thomas Edison to provide ventilation in his work around the ...
Heating of the windtower itself can heat the air inside (making it a solar chimney), so that it rises and pulls air out of the top of the house, creating a draft. This effect can be enhanced with a heat source at the bottom of the windtower ( such as humans, ~80 Watts each [ citation needed ] ), but this heats the house and makes it less ...
Research aiming at the development of natural ventilation systems featuring heat recovery have been made as early as 1993 where Shultz et al. [8] proposed and tested a chimney type design relying on stack effect while recovering heat using a large counterflow recuperator constructed from corrugated galvanized iron. Both supply and exhaust ...
