Technical Session 

Practical Application of Variable Frequency Drives 

This session provides an overview of Variable Frequency Drives (VFDs) in HVAC systems, focusing on installation, programming, electrical requirements, and sensor selection. It also addresses pump selection for variable speed operation, including turndown limits, pump and control curves, efficiency matching, parallel pumping with lead/lag control, and how differential pressure sensor location impacts system performance. The presentation concludes with a brief hands-on VFD demonstration showing real-time setup and control response.

Dinner Program

Inside the VFD: Power, Control, and HVAC Applications

This technical presentation provides a practical and theoretical overview of Variable Frequency Drives (VFDs) and their role in modern HVAC and hydronic systems. Attendees will explore the fundamentals of three-phase motor operation, VFD power conversion stages (rectifier, DC bus, and inverter), and the voltage-to-frequency relationship used to control motor speed and torque.
