Elevator Manufacturer Make Elevators More Energy Efficient

The skyscrapers can now be seen everywhere in the skyscrapers. In addition to skyscrapers, the elevator system can also help in other busy places, such as shopping malls and airports. A modern city has a large number of elevators, and some estimates that buildings consume about 40% of the world's energy, while elevators account for 2% to 10% of building energy. It is therefore important to reduce the energy consumption of the elevator, which can help building owners save money. Elevator Manufacturer Fuji is improving the energy consumption of elevators.

Currently, elevators require giant wire ropes to move up and down. Those ropes are very heavy: in a WTC, each rope weighs 20 metric tons - about two and a half elephants - you need a lot of bulky equipment and energy to push them to move.

The elevator industry is offering a relatively new elevator product called the Machine Room Elevator (MRL). Compared to hydraulic elevators, the use of MRL elevators can save a lot of energy (estimated 70-80%). Due to the more efficient design and balance provided by the traction equipment, the MRL's power feeders are also greatly reduced. The machine roomless elevator is a compact, lightweight, gearless machine with higher energy efficiency.

Reduce overall energy use through control strategies

The most energy efficient elevators now have:

Software and microprocessor based control instead of electromechanical relays

In-cab sensors and software that automatically enter idle or sleep mode, turn off lights, ventilation, music and video screens when idle

Destination dispatch control software for batch elevator stop requests, reducing the number of stops and minimizing wait times, reducing the number of elevators required

Personalized elevator calls for use with destination dispatch control, without cab control.

The new elevator control software provides elevator consultants with the tools to perform elevator banking traffic research. How the elevator cycle affects its energy flow. By observing the sporadic nature of the elevator operation, the number of floors traveled, the peak load period and the fact that the elevator is not always loaded to the rated capacity.

Manufacturers are now more focused on improving energy use in other systems, such as cab lighting, fans, doors, brakes and elevator controls. They use efficient LED lights in the cab panel, overhead and floor indicators. They include door drive motors that can enter standby mode or can be effectively recovered from the power source when not in use. These motors also support variable door opening and closing times, and their energy usage is considered in the overall control strategy.
