Development & Demonstration of Non-Intrusive Duct Lining Technology for Sealing/Rehabilitation of HVAC Ducts in Residential Buildings

摘要

Air leakage in forced air duct systems is now recognized as a major source of energy waste in both new and existing homes and commercial establishments. Research conducted by the Florida Solar Energy Center (FSEC), Advanced Energy Corporation (AEC), Proctor Engineering (PE), ECOTOP and other nationally recognized research organizations has shown that testing and sealing leaky distribution systems is one of the most cost effective energy saving strategies. Comparing the energy consumption between a leaky duct (in total around 3 in 2 holes) and a sealed duct, using the Duct-Blaster, revealed that nearly 30 percent energy is lost due to leaks (see Figure 1).
