ASHRAE特别项目SP43开发并实验验证了一个动态模拟模型，用于分析住宅强制暖风系统的热性能和能量利用。本文是一系列文章的第三篇，介绍了如何使用该模型来比较各种系统和控制选项，目的是为ASHRAE手册的设备卷生成信息。定义了系统部件效率和无量纲能量系数，用于描述熔炉、管道系统、系统诱导负荷和年度系统总性能。 这些因素由SP43模型生成，用于40多个示例案例，用于显示系统和控制变量对整体性能的影响。这些变量包括:炉子和排气类型、安装位置和燃烧空气源、炉子尺寸、夜间倒退、恒温器循环率、鼓风机操作策略、地下室绝缘水平、管道密封和绝缘、房屋和基础类型和气候。研究了四种房屋类型:带地下室的两层房屋和带地下室、爬行空间和楼板的牧场式房屋。 使用ASHRAE WYEC气象带对三种气候进行了检查:纳什维尔、匹兹堡和明尼阿波利斯。单位:I-PCITION:研讨会，ASHRAE交易，1986年，第92卷，pt。2B，波特兰，或

ASHRAE Special Project SP43 has developed and experimentally validated a dynamic simulation model for analyzing the thermal performance and energy utilization of residential forced-warm-air heating systems. This paper, third in a series, describes the use of the model to compare various system and control options, with the objective of generating information for the Equipment Volume of the ASHRAE Handbook.System component efficiencies and dimensionless energy factors are defined that describe the furnace, duct system, system-induced loads, and total system performance on an annual basis. These factors were generated by the SP43 model for over 40 example cases, selected to show 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. Four house types were examined: a two-story house with basement, and a ranch-style house with basement, crawl space, and slab. Three climates were examined using ASHRAE WYEC weather tapes: Nashville, Pittsburgh, and Minneapolis.Units: I-P
