E82EV751K4C 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.

E82EV751K4C 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.

E82EV751K4C 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. 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.

E82EV751K4C The use of variable frequency speed control devices on such loads is of great significance. 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.
