Our common energy-saving methods in life are:
1. Improve the mechanical transmission and electric drag system
2. Use (IPC-PFE series) electric energy regenerator to regenerate the braking electric energy
3. Update the elevator car lighting system
4. The use of advanced elevator control technology. However, if the installed elevator needs to be carried out, the best way is to use (IPC-PFE series) energy feedback device.
For (IPC-PFE series) electric energy feedback device, I still know its working principle. When the elevator is lightly moving up or heavy load is moving down, the motor is in the state of power generation
When the motor is going up at light load, the weight of the load is greater than the weight of the car, so the motor does not do work and the coil is still cutting the magnetic wire to generate electrical energy. The (IPC-PFE series) electric energy feedback device is to collect this part of electric energy and feed it back to the power grid. The same applies when the elevator is under heavy load. And after using the elevator feedback device, the energy saving rate reaches 20% -40%
Especially under the current national energy saving policy, building energy saving is a field of energy saving with great potential, and elevator energy saving can play a certain role in building energy saving.
