1. introduction. the building sector consumes as much as 20–40% of the total energy in many countries while the heating ventilation air-conditioning (hvac) system accounts for almost half of it .to save energy and improve indoor environmental quality, methods to promote the energy efficiency of the hvac system have been emphasized in recent years., ceiling fans have been widely used for a long time as an effective cooling equipment to create a sustainable indoor environment. however, it is rather difficult for the current measuring .... Ceilingfan.com shows which ceiling fans move the most air. see what gives a fan power, airflow efficiency, and why. the four areas that determine airflow are blade shape, blade pitch, distance from ceiling, and motor quality., ceiling fan airflow - doe requires ceiling fan manufacturers to test and publish cfm airflow ratings..
Ceiling fans with high airflow move more than 7000 cubic feet of air per minute (cfm). these fans are designed to keep significant amounts of air flowing in large areas.
