AC frequency converters are widely used in our daily lives. HVAC systems and secondary pressurization equipment are installed in new buildings and existing buildings around the world, as well as in urban infrastructure systems. The application of variable frequency technology can improve air quality. And indoor comfort, improve control, save energy, reduce maintenance costs, improve stability. Among them, the daily load fluctuation of HVAC equipment is very large. The use of motor frequency conversion speed control is one of the most effective measures to reduce costs. If the pump or fan reduces the average motor speed by 20%, it can save about 50%. Energy, which reduces the average speed by 50%, can save up to 80% of energy.
Reduce the total costIn the building automation design program, energy costs have a great impact on the total cost. If you can reduce energy use, you can save a lot of costs in a relatively short period of time. The PI500 series features automatic motor tuning, load adaptation, and other features to ensure that the drive is perfectly adapted to any motor and changing load. PI500 series inverters have low maintenance cost, can realize rapid return on investment in building automation, and can significantly save total cost.
