Assessment of Technology for Improving the Efficiency of Residential Gas Furnaces and Boilers. Interim Topical Report, March 1993-January 1994

摘要

The U.S. Department of Energy identified 21 design options for increasing furnace and boiler efficiency in their Advance Notice of Proposed Rulemaking for NAECA minimum efficiency standards. These design options may or may not improve efficiency. If they do, an economic assessment is made. The energy impacts of some of these options on the performance of base case furnace and boiler appliances were evaluated using data available in the general literature, experimental investigations, and a new, validated GRI computer model that simulates the operation of furnaces under specified operating conditions such as the DOE AFUE test procedure, including the steady-state test, the heat-up test, and the cool-down test. When appropriate, appliances currently available on the market that employ one or more of the design options were evaluated.
