VFD
A Variable Frequency Drive (VFD) is an electronic device that controls the speed and torque of an electric motor by varying the frequency and voltage of its power supply. It is commonly used in HVAC systems to precisely adjust the speed of fans, pumps, and compressors, ensuring that they only run as fast as needed. This not only enhances energy efficiency but also reduces wear and tear on the motor, extending its lifespan.
