The Coanda Effect was defined by Henri Coandă, who first recognised the phenomenon as, “the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.”
AirMasters harness the Coanda Effect not only to distribute air across a ceiling surface, but also to enable further tempering and reduction in velocity of supply air such that when the air falls into the occupied zone, its temperature should match that of the existing room air and its velocity will be reduced to approximately 0.15 m/s.
In combination with the heat exchanger, the Coanda Effect is at the heart of what makes AirMaster a draught proof ventilation solution.
