About the Seminar

How to Save Energy and Money with HVAC Fan and Pump Motors

This Realtime Online Seminar covers how to reduce the energy used by HVAC fan and pump motors in constant and variable air and water systems. Typically, on large HVAC systems fan motors are approximately 40% to 50% of the total prime mover energy used. Pump motors, depending on the type of HVAC system, are approximately 30% to 35% of the total energy used with refrigeration compressor motors being the other 15% to 25%. Using fan and pump curves and working mathematical equations known as affinity laws you will learn how and how much motor energy is reduced. You will also learn how to calculate motor brake horsepower using mechanical and electrical equations. Using examples you will learn how to calculate the dollar cost of a given motor and the dollar savings with changes in motor brake horsepower.

In this online seminar you will learn equations to determine fluid flow requirements for air and water systems (air, cubic feet per minute and water, gallons per minute) based on the conditioned space heating or cooling load. We will discuss the differences in how constant volume systems and variable volume systems work and how to optimize them by design or retrofit. We will also discuss other aspects of motors, such as typical yearly operating hours for motor sizes, motor efficiencies, etc.

You can participate in the seminar from your office, home, or anywhere you have access to the internet and a phone or VOIP. You'll have opportunities to interact with your instructor and colleagues in real-time during the four live teleconferencing sessions, as well as in the time between sessions.
