Abstract:
A method of cooling individuals in an industrial building, the method comprising:mounting a fan having a hub and a plurality of air foil blades with a substantially uniform cross-section of at least approximately 10 to 12 feet in length extending radially outward from the hub to a ceiling of the industrial building; rotating the fan so that the radially extending blades produce a moving column of air that is approximately 20 to 24 feet in diameter at a position adjacent the fan, wherein the rotation of the fan imparts a columnar air flow having velocity of approximately 3 to 5 miles per hour at a distance of 10 feet from the fan so that the fan entrains a volume of air to flow in a pattern throughout the industrial building so that the entrained air in the pattern disrupts the boundary layer of air adjacent the individual so as to facilitate evaporation of sweat from the individuals.
