摘要
为验证通断时间面积法热分摊技术工程应用的可行性,在石家庄、衡水、邢台、唐山等城市的既有建筑热计量改造中采用了该技术。通过对2010—2011年供暖季实际运行数据的整理与计算,给出了各热用户单位面积供暖耗热量以及各城市单位面积平均耗热量,然后根据历史运行数据以及入户调查结果对数据进行了综合统计分析。结果表明,基于通断时间面积法的热分摊技术能正确表征用户的用热需求大小,可以实现合理、公平的热计量目的。
To verify the feasibility of this method., adopts this technique in the reform of heat metering in existing buildings in cities of Shijiazhuang, Hengshui, Xingtai, Tangshan, etc. Provides the heat loss per unit area of each heat user and the average of each city, through sorting and calculating the operating data of the actual projects in the heating season of 2010-2011, then carries out a statistic analyses based on the historical operating data and the outcome from a household survey. The results indicate that the heat allocation technique based on on-off time and area method can characterize the users＇ demand for the heat correctly, and achieve the purpose of a reasonable and equitable heat metering.
