The future development trend of China elevator energy saving elevator

       Elevator power consumption is huge, is one of the largest energy consumption equipment. According to the China Elevator Association estimates that China's average daily electricity consumption per elevator about 40kWh, accounting for 5% of the entire building energy consumption.

       Traction machine, the heart of the elevator, through the planetary gears, helical gears, and worm gear transmission technology upgrading, at the end of the nineties of the last century, the permanent magnetic synchronous traction machine with its volume small, low loss, high efficiency, has developed into a new traction machine of the mainstream models, and occupy the market position of the mainstream.

       At present, the elevator traction machine mainly permanent magnet synchronous traction machine with traditional asynchronous traction machine, compared with the latter, permanent magnet synchronous traction machine of the utility model has the advantages are mainly embodied in the following aspects:

       In general, the permanent magnet synchronous traction machine is the future development direction of traction machine. Accordingly, energy saving elevator will become the future development direction of the industry.

       In the next few years, with the continuous advance of China's infrastructure, elevator production will maintain a steady growth, the growth rate will be between 15%-20%. With the continuous development of the elevator industry and the continuous implementation of China's energy-saving emission reduction policies, China's energy saving elevator production accounted for the proportion of total elevator output increased from 30% in 2006 to about 85% in 2014. In order to meet the national building energy conservation policy implementation, the local government has issued a lift to replace or transform the plan, will expire the need to replace the elevator, through the replacement or technical transformation to replace energy saving elevator.

       Therefore, the future of energy saving elevator market demand mainly consists of three aspects, one is the new demand, two is the replacement of the old elevator, three is the amount of energy saving. Consider China's elevator 60% technology from Japan, so when the old elevator replacement or technological transformation amount to 15 years ago elevator output is calculated based on the. 2006-2014 years, China's new demand and the amount of the replacement of the old elevator to the energy saving elevator demand situation as shown below:

       From the table, China's demand for energy-saving elevator is very large, the growth in demand is very strong, not taken into account in the transformation of the original elevator is the number of energy-saving elevator, 2008 - 2014 years of compound growth rate has reached 27.27%, greatly exceeded the growth rate of China's demand for elevator.
