Abstract:
A method of cooling individuals in an industrial building, the method comprising:mounting a fan having a lateral width of at least approximately 20 to 24 feet and a plurality of blades of at least approximately 10 to 12 feet in length to a ceiling of the industrial building; androtating the fan so as to produce a moving column of air that extends substantially across the lateral width of the fan, wherein the rotation of the fan imparts a 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 individuals so as to facilitate evaporation of sweat from the individuals.
