Download or read book Heat Balance and Efficiency Measurements of Central, Forced-air, Residential Gas Furnaces written by E. C. Hise and published by . This book was released on 1975 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residential central gas furnaces of the atmospheric combustion and sealed combustion types were tested in the laboratory and in residences. Complete heat balances were taken at steady-state operation, cyclic operation, and off-design conditions, and the instantaneous efficiencies were determined. The seasonal fuel utilization efficiencies were synthesized for the two types of furnaces and for a range of adjustment in four climates. Recommendations are offered for a high-efficiency furnace design and installation standards which will reduce fuel consumption by one-third.
