Do fans used for evaporative cooling require variable frequency control?
Thread Content
Evaporative cooling is required in the process; considering that the motor load of the fan is generally relatively low, not exceeding 10 kilowatt-hours. To save energy, if a evaporative cooling system has 2–4 fans, should variable frequency control be applied only to 1–2 of them? Or without frequency conversion, the motor is started and stopped entirely manually or remotely, depending on the cooling effect.
Variable frequency is used to achieve satisfactory heat exchange and energy-saving results; the temperature curve remains continuous, but the investment required is relatively high； With manual control, the temperature curve is stepped. It depends on what the original poster considers to be more important; the rich have their own ways of living and standard of quality of life, while the ordinary people have theirs.
