7 Part I – Saving Energy You save energy by improving the overall efficiency of the driven system. There are many energy wasters within a given system, but one component that should always be checked is the power input side or the electric motor. The BE$T program concentrates on improving the power input of the system. BE$T calculates the estimated energy that can be saved by using Premium Efficient motors and drives where applicable. Payback periods for motor efficiency upgrades are calculated and motor replacement timetables are recommended.

8 Why is Motor Efficiency Important?12/2/2017 Why is Motor Efficiency Important? - Wasted Energy $ 10 Hp motor running at full load Measured Power in - 8,025 Watts Power out = 10 Hp x 746 = 7460 Watts Efficiency = Power Out / Power In Efficiency = 7460 / 8025 Efficiency = .930 or 93.0%

9 12/2/2017 What is Higher Efficiency Worth? Even a 4.5 point efficiency gain is important. 40 HP Super-E with 94.5% efficiency compared to standard motor with 90% eff. Operating 50 weeks/year

10 BE$T – Basic Motor Calculations12/2/2017 BE$T – Basic Motor Calculations Annual Motor Operating Cost To find the annual operating cost of one motor (HP * .746Watt/HP * %ML * Hours * ¢/kWh) / Efficiency To find the annual operating cost difference between two motors (HP * .746Watt/HP * %ML * Hours * ¢/kWh) / {1/Enew– 1/Eold} HP = horsepower 0.746 is the number of watts in a horsepower %ML – the percent motor load I.e 75%, 100% etc. ¢/kWh is the cost of one kilowatt hour of electricity Enew– Eold this equation represents the energy the difference between the energy used by the two motors. %ML = percent motor load, Hours = annual operating hours, E = efficiency

11 12/2/2017 Obtain Even More Energy Savings by Using Drives on Variable Torque Loads Potential Energy Savings Air conditioning % Compressors % Central refrigeration % Blowers and fans % Feedwater pumps % When a VFD is added to a variable torque loads you can expect to save approximately 20% to 50% of the energy consumed without the VFD. If the load is constant then adding a VFD would actually add additional energy cost. The only advantage would be greater control of the motor’s speed.

12 Where do Drive Savings Come from? Look between the curves.12/2/2017 Where do Drive Savings Come from? Look between the curves. Typical variable torque Fan and Pump Curve The savings occur between the curves This generic graph shows a typical motor energy use curve and the curve of the energy used if a VFD was installed. The energy savings is the difference between the two curves.

13 12/2/2017 Why does this work? Variable Torque Pump and Fan Loads use the Affinity Laws, the required HP is a cubic function of rpm. 100% 75% % LOAD Fan or Pump Load Curve 50% Notice at full load the energy required is the same. At 50% of motor speed the energy required to move a variable torque load is about 20% of the motor load. 25% %Power ~ Speed3 0% 0% 25% 50% 75% 100% % SPEED / % FLOW

14 In words, using an adjustable speed drive saves energy by?Reducing the speed of a variable torque pump or fan significantly reduces the energy usage of the driving motor. The “why” can be summarized by a set of rules called the affinity rules. Flow produced by the system is proportional to the motor speed. Pressure produced by the system is proportional to the motor speed squared. Horsepower required by the system is proportional to the motor speed cubed.

15 An Example: A adjustable speed drive (ASD) running a variable torque load at 50% speed needs to deliver only 12.5% of the horsepower required to run it at 100 percent speed.

16 Not every driven system can benefit from using an Adjustable Speed DriveA constant torque system would not use a drive to save energy, but may use one for convenience. If you have a variable torque system. Look at the typical operating points or load profile of the system throughout the day to see if the system could benefit from a drive. The load profile determines the amount of energy savings that is possible. Does the system require full power all the time? Does the load on the system vary throughout the day? The load profile can be set in the program.
