Today’s Packaged Rooftop Systems Applied to Yesterday’s Installations

October 18, 2022

Just as we’ve seen cassette tapes give way to CD’s and CD’s give way to streaming through Bluetooth, the HVAC industry is seeing similar step function changes in systems technologies. Although much of the innovation is driven by regulatory changes, this path to compliance often yields the development of more advanced equipment and unit controls, or better yet, systems that are “ready for today.” 
This webinar will focus on today’s advanced packaged rooftop equipment when they’re placed in older installations.  What should you consider?  What are the best recommendations from systems experts?  What can engineers, contractors, operators, and owners expect as the HVAC industry journeys down this new technology path? 

Learn more about how today’s advanced packaged rooftop equipment can be placed in older installations.

Key Learnings:

  • Overview of the Department of Energy’s minimum efficiency changes and performance metrics
  • Understand how controls technology advancements bring serviceability, flexibility, and connectivity improvements (and sometimes challenges) to engineers and installing contractors
  • How these technology advancements help HVAC manufacturers gain efficiencies
  • How changes from constant volume to multi-speed and variable speed affect system design, operation, and installation
  • We’ll break the myth: “Constant volume is required in hospitals and in hurricane shelters.”
