Having said that, In the event the secondary pumps are a fixed-velocity variety, there will be instances exactly where the chilled h2o stream amount is both an excessive amount of or too fewer, not matching the cooling need and wasting Power.
The purpose of a VFD is always to change the velocity and torque of motorized aspects by different the voltage and frequency reaching the motor. A VFD serves to improve the effectiveness and energy-conserving qualities of electric motors.
VFD panels are typically developed with a power switch that's attached on the enter latest electric power resource to toggle the panel on and off. Furthermore, VFDs secure the circuits, and adjustable velocity drives Each time a brief circuit or overload normally takes location.
