摘　　要：针对目前供暖循环水泵电功耗较高情况,提出了利用变频调速技术调节循环泵流量的技术措施,分别就定压循环变频、恒压差循环变频、变压差循环变频3种控制方式进行了阐述,并通过实验数据说明了变压差循环变频控制方式的优越性。Because the power consumption of the circulating pumps in a heating system is comparatively high, frequency control techniques to control the flow of the circulating pumps were put forward. Three kinds of frequeuey control techniques were analyzed, including fixed pressure frequency control, constant pressure frequency control and variable pressure frequency control. According to the experimental data, the advantage of variable pressure frequency control technique was shown.
