Title:
LOW SPEED COOLING FAN
Document Type and Number:
WIPO Patent Application WO2000049342
Kind Code:
A3
Abstract:
A low speed cooling fan (100) that is designed to cool individuals located in large industrial buildings. A fan with a diameter between 15 to 40 feet consisting of a plurality of blades (316), with each in the shape of a tapered airfoil, is driven by an electric motor (304) to produce a very large slowly moving column of air. The moving column of air creates a uniformly gentle circulatory airflow pattern (200) throughout the interior of the building thus promoting the natural evaporative cooling process of the human body at all locations inside the building.
