Assessment of energy-saving elevator registration, household appliances can be similar to the five-tier system, there are AAA level, AA level, A-level, B-class, C-level five-tier system. If the AC two-speed elevator for the C-class, then the turbo-worm VVVF elevator can be B-class, permanent magnet synchronous host power than the turbine host small, so the use of permanent magnet synchronous host VVVF elevator can be included in the A level.

To get a lift at the AA level, it must be able to lift billom magnet synchronous motor can save more energy.

And access to AAA-class elevator which is the world’s most advanced energy-saving technology and application of the elevator products.

According to the above situation and the actual use of the elevator, we put forward the following energy-saving elevator rating hard index reference

AAA: permanent magnet synchronous machine, VVVF control technology, the use of elevator power generation up to 30-35%, does not directly impact the grid. This type of elevator energy-saving effect is good, no impact on the power grid is the real mature third-generation energy-saving elevators.

AA: Permanent magnet synchronous machine, VVVF control, can use the elevator power generation, such as energy feedback, but the energy feedback must meet the national grid access conditions, with the elevator power rectification and the stability of the power of the wire processing technology Impact. Energy feedback utilization rate of 20-25%, the elevator into the third generation of energy-saving elevator, but belong to the threshold of the third category of energy-saving elevators.

A: The permanent magnet synchronous machine, VVVF control, such large-scale elevator application has been nearly a decade, and sales are increasing year by year, the proportion of the market every year to improve power consumption outside the province, but also the protection of the environment than the turbine worm Elevator is good, is now the mainstream products, will also continue to increase the share. The elevator is the second generation of energy-saving elevators.

B: Turbine worm host, VVVF control, the elevator motor power is relatively large, but more energy than the AC double-speed energy-saving, but also the first generation of energy-saving elevator technology, but is gradually reducing production. The market also continues to have sales, the elevator before the mainstream products.

B-C: AC two-speed control, turbo-worm elevator host, PLC or older control, this type of elevator is mainly used in old lifts and elevators.

Old district to install the Nanshan model of the elevator

Bamboo Garden District, Shenzhen, the first to “eat crabs”, every week, both inside and outside the city guests to learn

Sunset, the 65-year-old Nanshan District Merchants Street Chui Chuk Yuen District Aunt Ma Jianli jump after the square dance, dragged his exhausted body to five, into the elevator, by floor, blink of an eye to the 7th floor home.

4 years ago, take the elevator home or Ma Jianli’s “dream.” Ma Jianli and other 14 owners after a long wait, hard “bargain”, the first to “eat crabs”, Bamboo Garden District, Shenzhen became the first successful installation of the elevator in the old residential area.

November 28 last year, five bamboo Chui Park official operation of the elevator. After more than four months of “run-in”, the elevator involved in the operation of tariffs, maintenance and other long-standing problem has not left the slightest “hidden danger”, the district an average of at least two groups of people each week to learn from outside the city.

Bamboo garden district was built in 1993, now residents are elderly. Shenzhen, such as the old residential areas abound, only Nanshan District, there are more than 100 buildings. Perspective Bamboo Park successful pilot, you can find a solution to the implementation of this policy to benefit the livelihood of the “key.”

Reported to build procedures like building a new building

“One-stop service” urgent implementation

Five owners Lu Xiao and lamented: “old residential area to install the elevator, it is easier said than done.

Where is the difficulty? He told reporters about the procedures related to information related to municipal and district levels of relevant departments of more than 10 stamped.

Lu Xiao and said that four years ago, the provincial authorities introduced measures to encourage the old residential areas to install elevators, they began to prepare. The end of 2013, Shenzhen introduced the “Shenzhen City, the implementation of the existing residential installation of elevators,” and the Bamboo Garden District as one of the city’s three pilot.
