摘　　要： 本文分析了适用于分户热计量的分户水平双管同程式供热系统分室温控时的水力工况变化规律。应用基尔霍夫第一和第二定律建立了系统水力工况模型,考虑双管系统的重力循环作用力,联立多方程得出了用户调节室温时系统水力的变化规律。研究结果表明:对于分户水平双管同程式系统,非调房间受调低室温房间的影响而关小温控阀,且距离调节用户越远所受影响越小;对某立管上的用户调低室温,其立管上的定压差调节阀将关小以维持系统水力平衡。 In this paper,for the household heat metering system,the variation trends of hydraulic regime of household horizontal two-pipe heating system with compartment temperature control were analyzed.Firstly,using the Kirchhoff＇s first and second laws,the models for hydraulic regime of each circuit were established.And then,considering the force of gravity circulation in the two-pipe system,the variation trends of hydraulic regime were obtained when occupants adjusted the indoor temperature.The research results indicated that for the household horizontal two-pipe heating system,the thermostat valve of non-regulated room would turn down automatically when it was affected by the thermostat valve of regulated room,and the thermostat valve which was far away from the regulated room would be affected little.Furthermore,when the occupants lowered the indoor temperature,the corresponding pressure regulating valve would turn down to keep the system hydraulic balance.
