BURNER-BOILER/FURNACE EFFICIENCY TEST PROJECT ANNUAL FUEL USE AND EFFICIENCY REFERENCE MANUAL HYDRONIC EQUIPMENT

摘要

A procedure for calculating the annual fuel use and seasonal efficiency of a particular heating unit has been developed at Brookhaven National Laboratory based upon laboratory measurement of steady state and part-load effi¬ciency. The Annual Fuel Use and Efficiency (AFUE) calculation procedure provides a simple and direct method by which detailed efficiency measurements can be translated to annual fuel use data for ranges of field variables including:geo¬graphic location, building design heat load, domestic hot water usage, and design fuel firing rate. The direct effi¬ciency measurements performed in the laboratory in conjunc¬tion with the AFUE procedure provide a standard quantitative method for comparison of heating units on a common and realistic basis.
