E82EV752K4C变频器节能主要表现在风机、水泵的应用上。风机、泵类负载采用变频调速后，节电率为20%～60%，这是因为风机、泵类负载的实际消耗功率基本与转速的三次方成比例。
E82EV752K4C当用户需要的平均流量较小时，风机、泵类采用变频调速使其转速降低，节能效果非常明显。而传统的风机、泵类采用挡板和阀门进行流量调节，电动机转速基本不变，耗电功率变化不大。
E82EV752K4C据统计，风机、泵类电动机用电量占·国用电量的31%，占工业用电量的50%。在此类负载上使用变频调速装置具有非常重要的意义。
E82EV752K4C目前，应用较成功的有恒压供水、各类风机、中央空调和液压泵的变频调速。
E82EV752K4C The energy saving of frequency converters is mainly reflected in the application of fans and water pumps. After the fans and pumps load adopt frequency conversion speed regulation, the power saving rate is 20% to 60%. This is because the actual power consumption of the fans and pumps is basically proportional to the cube of the speed.
E82EV752K4C When the average flow required by the user is small, fans and pumps use variable frequency speed regulation to reduce their speed, and the energy saving effect is very obvious. However, traditional fans and pumps use baffles and valves to adjust flow. The motor speed remains basically unchanged and the power consumption does not change much.
E82EV752K4C According to statistics, the electricity consumption of fan and pump motors accounts for 31% of the national electricity consumption and 50% of the industrial electricity consumption. The use of variable frequency speed control devices on such loads is of great significance.
E82EV752K4C At present, the most successful applications include variable frequency speed regulation of constant pressure water supply, various types of fans, central air conditioners and hydraulic pumps
