Design and Analysis of High Volume Low Speed Fan

Abstract

The High Volume Low Speed Fans are unlike conventional fans. They have a fan blade of about 2 meters incorporating the twist. The HVLS fans have wide applications in large storage spaces like warehouses, mosques and barns etc. They are manufactured and utilized in most countries except Pakistan and many people are oblivious of their benefits. HVLS fans are energy efficient fans with a capacity to replace almost seven conventional fans because of their high volume. The speed of HVLS fans ranges from 50 to 200rpm stimulating large segments of horizontal air column making them more effective in large spaces. They are helpful in removing moisture from the ground consequently minimize the safety risks. Keeping in view the advantages of HVLS fans and their nonexistent nature in manufacturing market of Pakistan it was decided to opt for the fabrication of HVLS fan as a part of our final year project. Pursuing this venture, not only the high cost of importing the HVLS fans can be avoided but we can also shed some light on the benefits of using HVLS fans in large spaces in comparison with the conventional fans.
