Description
Numerous studies of airflow and performance characteristics of circulating fans have been undertaken. Relatively few, however, are focused on aerosol transmission of airborne pathogens in large industrial spaces, a shortage all the more noticeable during the coronavirus disease 2019 (COVID-19) pandemic. To contribute to and improve the body of COVID-19-prompted guidance for the operation of circulating fans, Air Movement and Control Association (AMCA) International commissioned numerical-simulation studies of airborne-particle and aerosol transmission with large-diameter (greater than 2.1 m [7 ft]) ceiling fans (LDCF). The focus of the studies was warehouses in the United States, in which LDCF commonly are used for comfort cooling and destratification. The results, however, also are applicable to many manufacturing/industrial facilities. Join us for an in-depth look at this study, the research team, study results and ongoing guidance.

Objectives
- Evaluate the relationship between HVLS fan speeds and the reduction of airborne particle concentrations in large-scale warehouse environments.
- Determine the most effective fan operating directions and speeds to minimize localized hotspots and improve air dilution for worker safety.
- Develop operational recommendations for industrial building managers that prioritize both disease mitigation and occupant thermal comfort.
