Optimizing Energy Use with VSD Chillers

Chillers can account for 35 percent of HVAC energy use in many commercial buildings, but today’s Variable Speed Drives (VSDs) can cut a chiller’s annual energy cost by 30 percent or more. Learn more about how VSDs can optimize energy use at full and part load, as well as under off-design conditions in this one-hour free webcast.

Variable speed drives can provide ROI in under three years due to energy savings under variable real-world operating conditions. Join experts from Johnson Controls as they discuss how VSDs have evolved to be a proven investment for increasing chiller efficiency. In this webcast, we’ll cover: 

  • How VSDs adjust to off-design conditions, including optimizing energy use at full and part load with reduced tower water temperatures
  • The impact of lift on energy usage and chiller operations
  • Case study: The real-world energy savings with VSD technology
  • Applying VSDs to air-cooled chillers for energy savings
