Summary

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 conservation standards for direct expansion-dedicated outdoor air systems (DX-DOASes). These standards align with the latest American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1, Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 920 Standard, and are mandatory as of May 1, 2024. 
  
Join us for an insightful session where we delve into the critical aspects of DX-DOAS equipment and the new energy efficiency standards that engineers must adhere to. This webinar will provide a comprehensive understanding of dedicated outdoor air systems, the implications of the DOE's new regulations, and the steps necessary for compliance. We will also explore the AHRI 920 standard, its distinctions from AHRI 340/360, and introduce the Trane Horizon solution tailored for DOAS needs.
