Elevator Manufacturers are producing efficient elevators for mid-rise buildings, which is very energy efficient. These traction elevators have improved control, hardware and other systems that not only use less energy, but are also more compact, efficient, even capable of generating electricity, and can be used.
One of the biggest energy wastes in elevators is the drive system. Older drives, such as generator sets, continue to run, which can be very inefficient and result in significant energy wastage. They also cause hidden energy costs in the building because they generate a lot of heat. In recent decades, the steady development of AC elevator motors from DC to high efficiency is one of the important advances in elevator technology. Prior to the 1990s, elevator systems relied on DC power because this form of power supply made it easier to control the acceleration, deceleration, and stop of the elevator. Therefore, AC power is usually limited to freight elevators, and its comfort and speed are not as important as passenger elevators. However, by the end of the 1990s, more elevators had turned to AC motors.
The basic difference between these lifts is the application of the main drive speed controller and the drive of the hatch. The speed controller saves power (about 34.7%) and ensures that the elevator traffic is smooth. The two-speed drive consumes an average of 3,54 kW/h and the speed controller has a main drive speed of 2,3 kW/h.
Energy efficient elevators are widely used in elevator installations, replacing traditional physical wear and physical wear. The installation of energy efficient elevators does not require car rails and counterweights or fixed components. It can save up to 30% in equipment production and shipping costs. Elevator installation and commissioning takes 2-3 weeks.
In addition to using more efficient AC motors and regenerative drives. Most facility managers are looking for lighting, heating and cooling systems when looking for opportunities to reduce building energy consumption.
