Application of heat allocation technique based on on-off time and area method

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.
