Select Fans Using Fan Total Pressure to Save Energy
A recent estimate places the worldwide energy use of fans at about 23% of the world’s total energy consumption. ASHRAE started the process of defining the direction and goals of a program to reduce the energy consumed by fans in 2007. In examining the issues involved, it became apparent that while the obvious direction is to increase the energy efficiency of fans, improving the process of fan selection brings faster results. Both approaches need to be combined to achieve the best results.
