Abstract

La présente invention comprend deux modules d'aubes, parmi quatre modules d'aubes, orientés l'un vers l'autre et formant une première paire d'évacuation, les deux autres formant une seconde paire d'évacuation. La première paire d'évacuation et la seconde paire d'évacuation produisent un vent indirect et un vent direct en alternance, un espace intérieur pouvant être ainsi chauffé rapidement. La première paire d'évacuation et la seconde paire d'évacuation peuvent évacuer l'air selon des angles différent entre eux, ce qui permet de réduire au minimum les points morts auxquels l'air évacué n'arrive pas.
