Background
Research conducted under NBI PIER Element 4, Integrated Design of Small Commercial HVAC Systems, (Commission Contract 400-99-012) produced performance guidance for designers and operators on ways to improve the efficiency and operations of small package HVAC units. Many of these improvements could be integrated into a new "advanced" unit that would directly address performance and market impact objectives.
