热量计量收费供暖热网变流量压差控制点的位置分析
Location analysis of the pressure difference control point in variable flow rate heat metering charging systems
摘要：
结合一个热水供暖热网模型，探讨了变流量压差控制点的设置位置。计算分析结果表明，将控制点设置在第一个热用户与主干管的连接处、控制压差设为该处的设计工况压差既能保证热网中各用户流量又较节能。

Abstract：
Explores the location of pressure difference control points in variable flow rate systems with a hot water heating piping model. Calculating and analysing result indicates that the control point located in the joint of first user and main pipe and the pressure difference equaled to the design value can satisfy the demand flow rate of the users and save energy.
