ASHRAE Special Project 43 (SP43) has developed a dynamic simulation model for assessing the annual thermal performancea nd energy utilizationo f forced-warm-airh eating systems. Six previous papers on the SP43 project have described the model, its validation, and its use for evaluating system and control options, with the objective of generating information for the ASHRAE Handbook.
A previous paper described the results of model predictions that showed the effect of system and control variables on overall performance. These variables include furnace and venting types, installation location and combustion air source, furnace sizing, night setback, thermostat cycling rate, blower operation strategy, basement insulation levels, duct sealing and insulation, house and foundation type, and climate
This ASHRAE paper, seventh in the series, describes the results of 25 additional model predictions that supplement those previously made — including furnace sizing, climate for cases with night setback, blower afterrun control strategy, condensing furnaces with direct vents, closet furnace installations using attic air for combustion, and crawl-space furnace installations. The combined results of these predictions are expected to be the basis for information on annual system performance for the ASHRAE Handbook – 1988 Equipment Volume.
