About Course
This course was recorded from a live webinar that may include discussions from attendees. 

This program provides a broad scope of knowledge about commercial HVAC systems, from their basic operational processes to their individual components, and how these components function and interact. You’ll then learn how best to utilize this knowledge to achieve optimum HVAC system performance while reducing energy consumption.

The instructor will explain the math involved in calculating heat transfer from boilers and chillers to coils and the conditioned space. Fan curves, pumps curves, and various charts will be presented to facilitate your understanding of the operation of air, water and refrigeration systems. The air distribution system — from fan to ducting to the terminal box to the outlet, and the water distribution system — from the pump to piping to the heat exchanger, will also be explained and examined.This course is designed to be of value to anyone interested in achieving a better understanding of how HVAC systems work, and how to optimize them to achieve maximum performance and energy savings. Over one hundred photos and drawings are used in this seminar to help you visualize and more clearly understand HVAC systems and components.
