AMCA Issues COVID-19 Guidance for Large-Diameter Ceiling Fans
Air Movement and Control Association (AMCA) Intl., in collaboration with Concordia University and a team of engineers and scientists, has released the results of a year-long study of the impact of large-diameter (greater than 7 feet [2.1 m]) ceiling fans — also known as high-volume, low-speed (HVLS) fans — on coronavirus disease 2019 (COVID-19) exposure in a warehouse in the U.S.
Applicable to large, open, indoor spaces with low occupancy as well as to warehouses, the findings are based on more than 220 parametric computational-fluid-dynamics (CFD) simulations varying worker and packing-line locations and fan speed (20%-100%) with and without racking.
