ASHRAE Standard 90.1-2016 and Department of Energy (DOE) IEER efficiency regulations will have a direct impact on the U.S. rooftop air conditioning market and system design. This requires mechanical engineers to understand when certain systems are no longer allowed to be sold and what systems they’ll be specifying going forward.

Engineers will learn more about how fixed and variable speed compressor technology has evolved over time, and how to properly specify them into various system layouts (e.g. constant volume, VAV) to achieve the optimal system efficiency allowing consulting engineers to better meet their customer’s long-term energy efficiency needs.

Designers will learn how compressor technology and design architecture will affect future designs, given the new part-load efficiency standards.

Learning objectives:

  • Illustrate the importance of part-load efficiency in HVAC systems design
  • Understand the impact of ASHRAE Standard 90.1-2016 and Department of Energy (DOE) IEER efficiency regulations on the U.S. rooftop air conditioning market and system design
  • Outline evolution of compressor and capacity modulation technology in rooftops
  • Explore, in detail, the features and benefits of the latest fixed and variable speed scroll compressor technology and how it applies to rooftop cooling system designs.
