Is a VFD a CostEffective Option for Your Application

4 hours ago

1. A VFD varies the speed of a three-phase, alternating current (AC) induction motor by adjusting the voltage and frequency of the motor's input power (see Image 1). Varying the speed of the motor improves efficiency by changing the pump's output to match actual pressure/flow requirements. Any new or existing pump system with dynamic demand is a candidate for a VFD installation. If the pump often operates at a low flow rate, controlling motor speed with a VFD will result in much lower energy costs compared with running the motor at full speed and throttling its flow output with a control valve. Because required pump motor power increases at a much faster rate than flow, pumping fluid faster than necessary can alter energy use significantly. In addition to reducing power consumption, a VFD can also help reduce mechanical wear, maintenance and related costs. A VFD's ability to dramatically increase energy efficiency when used to control a centrifugal pump (see Image 2) is explained by th...

Frequently Asked Questions

What are affinity laws?

The affinity laws are a set of rules to describe the interconnected relationships between speed, flow, power, and pressure seen with fans, turbines, and similar devices. These rules are critical for heating and cooling installers, who must select products appropriate to their needs and calibrate them correctly.

What are the basic fan laws?

Understanding Fan Laws

  1. The affinity laws for fans are used in HVAC to express the relationship between variables involved in fan performance and power. ...
  2. Volume of Airflow (m3/h) What happens to flow rate if the impeller speed changes (first law) Pressure (Pa) What happens to system pressure if the air volume rate changes ...
  3. The volume of air moved by a fan changes in direct proportion to the change in speed of the fan impeller and can be calculated as follows: V2 = ...

How do you calculate hydraulic flow?

Multiply the cross-sectional area by the flow velocity, provided in unit of length over unit time squared. If the cross-sectional area and flow are truly perpendicular, the flow rate angle is zero degrees. The value you just calculated is the hydraulic flow.
