Understanding Energy Efficiency in Fans
Definition of energy efficiency
Energy efficiency in fans refers to the ability of a fan to convert electrical energy into useful kinetic energy, while minimizing wasted energy. It is a measure of how effectively a fan operates, utilizing the least amount of power to achieve a desired level of airflow or cooling. Energy efficiency is typically measured by the fan’s airflow output per unit of power input, expressed in terms of cubic feet per minute (CFM) per watt (W). The higher the CFM/W ratio, the more energy efficient the fan is.
