An AHU (Air Handling Unit) electrical panel equipped with VFD (Variable Frequency Drive) and bypass operation functionality is a pivotal element in modern HVAC systems. The VFD regulates the speed of the AHU fan motor based on demand, optimizing energy efficiency and precise temperature control. In case of VFD malfunction or maintenance, the bypass operation seamlessly transitions to direct-on-line mode, ensuring uninterrupted system performance. This integrated solution enhances energy savings, reduces operational costs, and maintains reliable HVAC operation. It’s an indispensable component for achieving both sustainability and operational efficiency in commercial and industrial buildings, contributing to a comfortable and eco-friendly indoor environment.
