下面仅以再生能源循环利用这一问题探讨计算如下:一般变频调速电梯制动产生的再生电能采用电阻耗能方式吸收并变为热能释放,其功率近似为:Q=P×K

     Q:以热能形式释放的功率

     P:电梯电机功率

     K:制动频度,对于高层电梯一般取值为K=35%

如速度3米/秒,载重量1250公斤的电梯,其电机功率约为26.3KW,电梯制动的能耗Q= 26.3KW×35% =9.21KW

按平均每天12小时计算,每年365天运行,则电梯制动过程的能量损耗为:9.21 KW×4380小时=40340度/年。

宾利电梯复合变频节能技术可将损耗能量的98%重复利用,因此每年可节省电能39533.2度;民用电以0.65元/度计算,每年能节约电费约为:39533.2×0.65 = 25696.58元,即仅一台电梯可省电费约2.57万元。

宾利电梯由于采用绿色环保节能型永磁同步无齿曳引机和复合变频节能技术使得电梯系统的电能大大节省,为宾利电梯的用户每年节省大笔运营费用。


        Below with only renewable energy recycling this issue discusses calculation is as follows: general VVVF elevator braking produce renewable electricity resistance energy consumption way and incorporated into thermal energy is released, its power approximation is: Q = P * K

        Q: power released in the form of heat energy

         P: elevator motor power

         K: for example, the average value of the elevator is 35 percent

         If the speed is 3 m/s, the lift with a weight of 1,250 kilograms, the power of the electric motor is about 26.3 KW, and the energy consumption of the elevator brake is 26.3 KW times 35% = 9.21 KW

         The energy loss of the elevator braking process is 9.21 KW * 4380 hours = 40340 degree/year, which is calculated at an average of 12 hours per day, 365 days a year.

     Bentley elevator compound frequency-conversion energy saving technology can reuse 98% of the dissipated energy, thus saving the energy of 39533.2 degrees every year. The electricity consumption is calculated at 0.65 yuan/degree, and the electricity cost is about: 39533.2 * 0.65 = 25696.58 yuan, which means that one elevator can save about 25,700 yuan.
