The use of the elevator now more and more, in hotels, office buildings and other electricity situation investigation statistics, the elevator power consumption accounts for more than 17% to 25% of the total power consumption, second only to air conditioning power consumption, higher than lighting electricity, water supply, etc.
With the continuous expansion of modern production scale and continuous improvement of people's living standard, the contradiction between power supply and demand is becoming more and more prominent. Statistics show that the electric power of motor drive load accounts for over 70% of the total power consumption. Therefore, it is of special importance to save electric energy by the motor drive system. As the economy continues to grow, people are becoming more and more efficient in the use of elevators. If energy efficiency is achieved in this area, it will bring huge economic benefits. Premise is to popularize the use of the elevator energy-saving concepts and, at this time we will notice the elevator energy-saving effect and the power of the elevator, elevator the balance of the whole system, elevator system, etc., the following categories of better energy saving effect:
1、The higher the elevator, the more braking, the more energy saving;
2、The more newly installed elevators, the more mechanical inertia, the more energy saving;
3、The longer the use of the elevator, the greater the friction force, the more energy saving;
4、The faster the elevator, the more braking, the more energy saving;
5、The more frequent elevators, the more braking and energy saving.
Finally, there is the question of life expectancy, which is generally 8 -- 10 years, and it takes up to 10 hours to work, so the elevator energy saver doesn't retire before the elevator.
