电梯作为高层建筑运输人及货物的设备,自发明至今一直为人们的出行提供便捷;但诸多研究表明电梯能耗占高层建筑总能耗的20%左右,尤其是在能源供需矛盾日益突出的今天,电梯能耗已成为制约其发展和应用的主要问题。为降低电梯能耗,达到电梯节能运行的目的,结合曳引电梯的结构特点、运行特性及能耗特性,提出并设计一种新型的电-液混合驱动高能效曳引电梯节能系统。对传统电梯的运行特性进行分析,进而对提出的新型节能原理进行分析。建立曳引电梯能耗的仿真模型,并对传统电梯和节能电梯运行过程中的能耗进行仿真分析,仿真结果表明新型节能系统的节能效果明显。搭建电梯节能综合试验平台,通过在高层建筑进行能耗试验,验证仿真模型的准确性,试验结果表明新型节能系统的节能效率约为10%~14%。本文的研究成果不但是曳引电梯节能方面的发展方向之一,而且在其他垂直提升机械中也具有较好的应用前景。 Elevator as a high-rise building transportation of people and goods equipment, since its inception has been for the convenience of people traveling; but many studies show that the elevator energy consumption of high-rise buildings accounted for about 20% of total energy consumption, especially in energy supply and demand increasingly prominent today , Elevator energy consumption has become the main problem restricting its development and application. In order to reduce energy consumption of elevators and achieve energy-saving operation of elevators, a new type of energy-saving hybrid system is proposed and designed based on the structural characteristics, operational characteristics and energy consumption characteristics of traction elevators. The operating characteristics of traditional elevators are analyzed, and then the new energy saving principle proposed is analyzed. The simulation model of energy consumption of traction elevator is built, and the energy consumption of the traditional elevator and energy-saving elevator is simulated. The simulation results show that the energy-saving effect of the new energy-saving system is obvious. The elevator energy-saving integrated test platform was set up and the energy consumption test of high-rise building was carried out to verify the accuracy of the simulation model. The experimental results show that the energy-saving efficiency of the new energy-saving system is about 10% ~ 14%. The research results of this paper are not only one of the development directions for energy-saving elevator traction elevator, but also have a good application prospect in other vertical lifting machinery.
