住宅小区天然气供暖用气指标的研究

Study on Natural Gas Consumption Indexes for Heating in Residential Area

以北京使用天然气供热锅炉房为热源的住宅小区为例,通过数理统计方法得到北京市住宅小区供暖期供暖用气指标,分析了供暖用气的月、日用气规律。探讨了气象条件对供暖日用气负荷的影响,日用气负荷与室外日平均温度、日平均风速、日总辐射量关系密切,与日平均相对湿度、降水量关系不密切。建立了数学模型,得出了日用气负荷与室外日平均温度、日平均风速、日总辐射量的关系。

Taking a residential area using natural gas heating boiler plant as heat source in Beijing for example, the gas consumption indexes for heating during heating period in residential areas of Beijing are obtained by mathematical statistic methods. The rules of daily and monthly gas consumption for heating are analyzed. The influence of meteorological conditions on daily gas load for heating is discussed. The daily gas load has colse relations to outdoor daily mean temperature, daily mean wind speed and daily total radiation, but the daily gas load has not close relations to daily mean relative humidity and daily rainfall. The mathematical model is established, and the relations of daily gas load to outdoor daily mean temperature, daily mean wind speed and daily total radiation are obtained.
