High-Velocity Small-Diameter Duct System

Current engineering guidelines for forced-air space-conditioning systems use methodologies that were developed more than 50 years ago and based on the concept that buildings are dominated by externally driven shell loads. Significant advances in thermal enclosure performance suggest that traditional space conditioning systems should be rethought to better handle loads that are more strongly influenced by internal gains.
In a new unoccupied test house in Pittsburgh, Pennsylvania, the U.S. Department of Energy’s Building America team IBACOS assessed the performance of a commercial high-velocity small-diameter air distribution system. The purpose was to test how the system handled the room-to-room cooling and heating loads with respect to Air Conditioning Contractors of America (ACCA) Manual RS criteria for thermal uniformity and ASHRAE Standard 55-2010 criteria for temperature variation with time. The main goal for using the small-diameter (2-in.) duct system was to simplify the installation of ductwork inside conditioned space.
