There's two kinds of electrical power and the first a single we’ll check out is DC or immediate present. This is the simplest form and we get this from batteries, photo voltaic panels and so forth. 

VFD panels are generally intended with an influence swap that is certainly attached to the enter latest power source to toggle the panel on and off. Additionally, VFDs safeguard the circuits, and adjustable speed drives whenever a brief circuit or overload will take location.

A variable frequency drive is usually a machine utilized to control the torque and velocity of An electrical motor by varying voltage and frequency source. Besides supplying you with total control of your respective motor operations, VFDs let for precise control around motor speed to save lots of Electrical power.

VFD AHUs control their velocity by the use of a opinions signal in the differential stress sensor within the duct connecting to the AHU.

Nevertheless, blindly slowing down cooling tower fans may bring about higher condenser h2o return temperature, leading to very poor chiller general performance.
