Full Description
Computer procedures were developed for modeling stack dampers with delayed operation between burner shut-off and damper closure. Corrective factors for the time delay have been obtained and a quantitative theoretical rationale is used to evaluate the effect of the time delay on the seasonal efficiency of fossil fuel-fired residential heating equipment. Finally, an implementation procedure is outlined for incorporating this rationale into the existing DOE furnace/boiler seasonal efficiency test and evaluation procedure.
