HVLS Fans For Cooling in Buildings

The remarkable thing was that when I visited the factory making HVLS (High-Volume-Low-Speed) destratification fans in Italy it was a warm day. It was 20 minutes into the journey with the air conditioning running at full blast that the car came down to a comfortable temperature but all day inside the factory it had been cool and refreshing. Hot outside, yet cool inside. It had been a good day - learning more about HVLS fans and discovering the nuts and bolts about apparent temperature. Moving say 850,000m3/hr of air aught be massively noisy and I fully expected something to fill my ears. I listened, I felt the refreshing wash of air movement, and I think I detected a faint hum. My host said that noise was coming from the factory next door. Not convinced, I ambled across the factory floor towards the back wall adjacent to the next door property and right enough it was the factory next door. Of the gently sweeping HVLS fan above my head I heard diddly squat.
