How does inverter save energy?
- If you run a fan or pump and you have damper (valve) control or control it with an inverter, the relation between the air flow (flow rate) and the required power, as well as the relation between the power supply frequency fs (Hz) and operating frequency with the inverter fINV (Hz) are as shown in the table at right.
- If the air flow rate is low, the energy saving effect is particularly great.
