04 May Saving Strategy pushing the elevator industry
China Elevator Association statistics show that from 2011, China has become the world’s largest elevator doing my part of the country of use, as of the end of 2014, the national total in the elevator reached 3.598 million units, more than one billion passengers a day service people.
20150520142211651165 each elevator according to the average daily consumption 40 kwh calculations, the total number of operational energy lift every day more than 144 million kwh, the annual power consumption 52.6 billion kwh, equivalent to 10 Yellow largest power station – Xiaolangdi hub of annual generation 2014 power generation capacity, or the equivalent generating capacity of the Three Gorges Hydropower ranks first in the world 98.8 billion kwh of 53.2%.
Such a huge number of daily operation of the elevator, the elevator’s energy consumption has become an urgent and practical issue. April 22 is the 46th Earth Day, this year’s theme is “cherish the earth’s resources, changes in development – to improve the efficiency of resource use.”
According to the survey elevator industry now we have a variety of the latest energy-saving technology has been applied. For example, permanent magnet synchronous motor drive gearless traction machine. This widely used hoisting machine, higher than the traditional worm-type traction machine efficiency, more energy efficient. In addition, there are highly efficient energy converters feedback, the new LED lighting, intelligent energy-saving technologies, as well as intelligent traffic management systems such NEURAL intelligent carrier scheduling, etc., can make significant energy saving elevator.
On the status of China’s current use of the elevator, since the lack of attention to the energy consumption of the elevator before, coupled with technical strength limit, currently running the country elevator, the worm gear elevator, AC two-speed elevator still a large proportion, with rising energy prices, this part of the elevator operating costs will be higher, will be gradually phased out, transformation and renewal. With the rapid development of science and technology, new technologies are emerging, energy consumption is bound to lift more and more low, the application of new technologies, energy-saving advantages elevator efficiency, energy efficiency will become increasingly prominent, cherish the earth’s resources, changes in development ways to improve the efficiency of resource utilization will also be more thoroughly implemented.
