More Facts about VFDs and Major Energy Savings
A VFD is a system for controlling the rotational speed of an alternating current (AC) electric motor. Used in commercial and industrial buildings to control the speed of fans and pumps in HVAC systems, VFDs are reliable electronic devices that consume less energy than mechanical flow control systems. By controlling the frequency of the electrical power supplied to the motor, drives offer you major energy savings of up to 80% on your energy bill. 
Since physical laws that govern centrifugal fans and pumps dictate that the volume of air or water decreases directly with fan or pump speed, and that power consumption decreases with the cube of speed, then a small reduction in speed produces a significant reduction in power consumption. Adjusting fan and pump speeds requires less energy than methods where motors run continuously at full speed. VFDs also reduce amps during motor starting which lowers demand charges, a significant part of your electric bill in commercial and industrial buildings.
With average ROIs of 6 months to 2 years, you will see results quickly. With energy savings up to 80%, VFDs aren’t only “green” for the environment but will also support the Environmental Protection Agency’s (EPA) effort to improve energy efficiency. More importantly, doing so makes good business sense and demonstrates corporate environmental consciousness.
In addition to energy savings, drives reduce wear and tear during operations which means less equipment maintenance costs. They also reduce 
equipment noise in the building, reducing tenant and employee complaints commonly caused by fan noise and duct rumble. Mechanical controls can be expensive to maintain while VFDs use tactics such as inherent soft-starting to reduce wear to motors and other system Components making VFDs much less costly to maintain than mechanical controls.
As an added plus, you won’t have to worry about frequent readjustments since frequency drives provide accurate and repeatable control of HVAC settings.
