Variable Frequency Distribution Box Principle
The working of VFD is based on the control of frequency and voltage simultaneously through a PWM inverter, it is used to control the speed of AC motor-driven applications. At the same time, they extend equipment lifetime, optimize processes, and reduce maintenance requirements. Did you know a VFD can help. A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, VVVF drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and. Variable air volume (VAV) systems enable energy-efficient HVAC system distribution by optimizing the amount and temperature of distributed air. Appropriate operations and maintenance (O&M) of VAV systems is necessary to optimize system performance and achieve high efficiency.
