Measurement of Dynamic Response and Seasonal Efficiencies of Central Space Heating Furnaces 集中供暖炉动态响应和季节效率的测量
为伊利诺伊州芝加哥市的一栋单层住宅,测定了一台电管道加热器(输入47000 Btu/h)和一台配备动力燃烧器的先进燃气炉(输入73000 Btu/h)的每小时动态响应和季节性能耗。该房屋的居住面积为1150平方英尺,配备了强制alr分配系统,测试期间无人居住。安装仪器以获取每小时的电力和天然气消耗量、循环行为以及温度、太阳辐射、风速和风向的同时室外天气数据。数据收集时间为1985年11月27日至1986年5月22日,而电力和燃气供暖系统每周都会作为热源依次切换,室内温度保持在70华氏度。季节性能源消耗由传统方法确定,首先将能源消耗与室外温度关联,然后使用长时间标准化为一个完整的季节- 术语平均bin天气数据。动态每小时响应是通过每小时燃气或电力消耗与室外天气数据的统计相关性建立的。室外温度和太阳辐射都是重要因素。然而,研究发现,室外温度对每小时消耗量的影响滞后时间短于太阳辐射。最后,使用DOE 2.1b模拟模型预测房屋的季节性能源消耗。单位:I-PCITION:研讨会,ASHRAE交易,1987年,第93卷,pt。田纳西州纳什维尔2号
The hourly dynamic response and seasonal energy consumption of an electric-duct heater (47,000 Btu/h input) and an advanced gas-fired furnace (73,000 Btu/h input), equipped with a powered burner, were determined for a one-story house located in Chicago, Illinois. The house had a living area of 1150 ft2, was equipped with a forced-alr distribution system and was uninhabited during testing.Instrumentation was installed to obtain hourly electric and gas consumption and cycling behavior and concurrent outdoor weather data of temperature, solar radiation, and wind speed and direction. Data were collected from November 27, 1985, to May 22, 1986, while electric and gas-fired heating systems were sequentially flip-flopped as the heating source on a weekly basis, and the indoor temperature maintained at 70 F.Seasonal energy consumption was determined by the traditional approach by first correlating energy consumption and outdoor temperature and then normalizing to a full season using long-term average bin weather data. Dynamic hourly response was established by a statistical correlation of hourly gas or electric consumption and outdoor weather data. Both outdoor temperature and solar radiation were found to be important factors. However, the time lag for the effect of outdoor temperature on hourly consumption was found to be shorter than for solar radiation. Finally, the DOE 2.1b simulation model was used to project a seasonal energy coPsumption for the house.Units: I-P
