PURPOSE: A Coanda air intake, and a ventilation system including the same are provided to improve the attracting efficiency by increasing the Coanda effect. CONSTITUTION: A Coanda air intake is formed in the bottom end of a supply pipe, and supplies the air to indoor. The Coanda effect is maximized by the fluid speed difference of an upper panel(200) and a lower panel(300) formed inside of a body at a different curvature radius each other. The air is supplied along the bottom surface of a ceiling by the Coanda effect, and hot and unpleasant air covering the ceiling flows in.
