随着城市集中供热的大力发展,热网控制系统不断的完善。但对各地的热网监测系统而言传统换热器入口阀门采用手动调节的方式,根据温度的变化调节换热器入口的阀门开度,温度高于设定温度时增大开度,反之减小开度,其调节速度虽然快,但稳定性极差,调节温度经常在目标温度上下 With the vigorous development of urban central heating, heat network control system continues to improve. However, the heat network monitoring system around the traditional heat exchanger inlet valve manually adjust the way, according to the temperature changes to adjust the heat exchanger inlet valve opening, the temperature is higher than the set temperature increases the opening, and vice versa Small opening, although the adjustment speed is fast, but the stability is very poor, adjust the temperature often at the target temperature
