The evaluation of energy-saving elevator registration can be similar to the five-level system of household appliances.

The evaluation of energy-saving elevator registration can be similar to the five-level system of household appliances, or AAA,AA,A,B,C five-level system. However, if the AC two-speed elevator is of Class C, then the turbine worm VVVF elevator can be of Class B, and the power of the permanent magnet synchronous host is smaller than that of the turbine worm host, so the VVVF elevator using the permanent magnet synchronous host can be included in Class A.

To obtain an AA-level elevator, it must be able to save more energy than a permanent magnet synchronous motor elevator.

The AAA elevator is the world's most advanced energy-saving technology and the application of elevator products.

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

AAA: Permanent magnet synchronous host, VVVF control technology, elevator power generation utilization reaches 30-35%, does not directly impact the power grid. This type of elevator has good energy-saving effect and no impact on the power grid. It is a truly mature third-generation energy-saving elevator.

AA: Permanent magnet synchronous host, VVVF control, can use elevator power generation, such as energy feedback, but energy feedback must conform to the national grid access conditions, with elevator power rectification and string wave stabilization technology without harmful impact on the grid. The energy feedback utilization rate reaches 20-25%, and this type of elevator enters the third generation of energy-saving elevators, but it belongs to the third type of energy-saving elevators that enter the threshold.

A: Permanent magnet synchronous host, VVVF control, this kind of elevator has been widely used for nearly ten years, and the sales volume is increasing year by year. The market proportion is increasing the power consumption liang every year. It also protects the environment better than the turbine worm elevator. It is the mainstream product now and will continue to increase its share. This type of elevator is the second generation of energy-saving elevators.

B: Turbine worm host, VVVF control, this type of elevator motor power is relatively large, but more energy-saving than AC two-speed, is also the first generation of energy-saving elevator technology, but is gradually reducing production. There are still sales in the market, which was the mainstream product of elevators before.

B- C: AC two-speed control, turbine worm elevator host, PLC or older control mode, this type of elevator is mainly the old elevator and freight elevator.
