变频技术在热水供暖系统中的研究和应用

Research and Application of the Frequency Conversion Technology in Hot Water Heating System

变频技术,是通过频率的变化近而改变水泵转速来改变系统循环水量的变频调速方法。正是将水泵转速纳入了调节范围,通过对水泵转速的调节,使流量、扬程同时变化,从而达到质量——流量优化运行的目的。

The frequency conversion technology, is close by the frequency change but changes the frequency conversion speed regulation method coming to change the system circulation water yield water pump rotation rate. The rotation rate has been brought the water pump into adjustment range through regulating the rotation rate. It makes change both rate of flow and simultaneous, and achieves the purpose that the mass rate of flow optimization can be worked well. they will be able to save large amount of electric energy and operation cost, it will help us to strain situation relieving electric power and enhance the economy supply heating.
