From "energy conservation" to "energy generation", the energy conservation of elevator system has achieved a qualitative leap

Guide: from energy conservation to energy generation, the energy conservation of elevator system has achieved a qualitative leap, and as a frequency converter enterprise that plays an important role in it, we have gone through an uneven road

on the eve of the national two sessions in 2011, Premier Wen Jiabao said in his interaction with the people that the central government plans to build 36million new affordable housing units in the next five years, The assessment and accountability mechanism will be implemented to the provincial, municipal and county governments at all levels, and those places where the efforts to stabilize housing prices and promote the construction of affordable housing are ineffective, thereby affecting social development and stability, will be investigated. This is undoubtedly a major positive news for the real estate industry and a sound drum to promote the development of the elevator industry

has become a product with different uses

according to relevant statistics, in the past 201, there has been a mature test standard for thermal viscosity testing internationally - ASTM f19210, China shipped 365000 elevators (including 45000 escalators), an increase of 40% over the same period in 2009, of which 330000 were shipped to the domestic market, an increase of 48% year-on-year. In the Chinese market, 458 enterprises hold elevator manufacturing licenses. China has become the world's largest elevator producer and the world's largest new elevator installation market, with a year-on-year decrease of 69%. Due to the homogenization of product quality and technology, coupled with the rapid development of elevator market in China's second and third tier cities and moderately developed regions, in recent years, a number of excellent small and medium-sized elevator enterprises have sprung up, making the market share of major elevator enterprises continue to decline, and the market share of small and medium-sized enterprises has gradually increased to about 35%

with the increasing use of elevators, according to the survey and statistics of the power consumption of hotels, office buildings and other commercial buildings, the power consumption of elevators accounts for 17% to 25% of the total power consumption, second only to the smooth transfer power that should be processed at both ends of the air tight sample. The frequent braking of elevator consumes a lot of electric energy, and the energy saving of elevator has a great market space. At present, green energy-saving elevator is not only a concept, but also an important link directly linked to the economic benefits of building operation. Although the elevator system accounts for only 4% of the investment of builders, in the long run, ignoring this 4% investment will also bring considerable economic losses

the energy saving of elevator has experienced two changes. For the first time, frequency converter speed regulation is used to replace asynchronous motor voltage regulation and speed regulation, so as to improve the operating efficiency of the motor, which is energy saving. Although the electric energy consumed by the elevator is greatly reduced after the frequency converter is adopted for speed regulation, a large amount of electric energy is still consumed on the braking resistance when the elevator is braking. Therefore, the second energy-saving reform is to feed back the energy generated during elevator braking to electricity for other nearby electrical equipment, which has actually become energy generation

from energy conservation to energy generation, the energy conservation of elevator system has achieved a qualitative leap, and as a frequency converter enterprise that plays an important role in it, we have gone through an uneven road. Due to the high requirements of the elevator system on the frequency converter, at present, there are not many domestic enterprises that can produce the frequency converter for elevator, and even fewer domestic enterprises that can produce the frequency converter to realize energy feedback

elevators will gradually enter the energy generation era from the energy-saving era. In the face of such a broad market, we expect every inverter enterprise to confidently say: give it up
