摘　　要：针对采用电动阀通断式调节的供热系统,通过计算机模拟系统在室内流量阶跃性变化时的管网运行工况,分析得出调节用户的调节会引起未调节用户和整个管网的工况的波动,不利于系统的运行;采用立管热力入口安装自力式压差控制器,循环水泵采用近端变频定压的控制方式能够维持管网工况的稳定,并降低运行成本,适合室内流量阶跃性变化时管网的运行.Using the computer to simulate the heating system＇s working condition when the indoor flux change suddenly, the adjustment of the adjusted users would make the working condition of the unadjusted users and the whole network change greatly, and it is harm for the working of heating system. The working condition could keep stable by using pressure control valve and frequency conversion pump, and reduce the cost of heating system working.
