    Summary

    Discover how Dedicated Outdoor Air Systems (DOAS) are transforming HVAC design by enhancing humidity control and energy efficiency, as the new Department of Energy (DOE) minimum efficiency standards become effective in May 2025.  With this new efficinecy standard DX-DOASes will be listed to the DOE and subject to enforcement redefining compliance for engineers. Join our webinar to explore the critical implications of these regulations, including an in-depth look at AHRI standards and the innovative Trane Horizon solution tailored for DOAS applications.

    Dedicated Outdoor Air Systems (DOAS) are pivotal in modern HVAC system design, significantly enhancing humidity control, energy efficiency, and indoor air quality. In response to evolving energy conservation needs, the Department of Energy (DOE) has issued a final rule establishing stringent energy efficiency minimums for direct expansion-dedicated outdoor air systems (DX-DOASes). These requirements align with the latest Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 920-2020Standard.

    Learning Objectives: 

    • Understanding DOAS: Gain a clear understanding of what a dedicated outdoor air system is and its role in HVAC design. 
    • AHRI Standards: Learn about the AHRI 920 2020 standard and how it differs from AHRI 340/360. 
    • DOE Efficiency Standards: Understand the minimum efficiency standards for DX-DOAS equipment as mandated by the Department of Energy. 
    • Industry Implementation: Discover how new standards are being implemented across the industry and what engineers need to be vigilant about.
