Since its inception it has become widely accepted worldwide. In more recent years it has been realized that the SEF depends not only on the fan type and the fitting geometry but also on the fan design and manufacturing.
WebThe fan system efficiency, i.e., the ability to convert electrical power to air power, is a function of the fan’s aerodynamics and the motor, transmission and controller efficiencies, with the primary factor being the aerodynamic efficiency of the fan. WebFans may be plagued by five operational problems: noise, vibration, capacity, control, and mechanical failure. Often, several problems occur simultaneously. Solving an operational problem often goes hand-in-hand with the optimization of fan energy requirements.
