摘要
以"双碳"目标为指引,受环境保护、降本增效等因素影响,各大电梯生产及使用企业对电梯能效测试技术的需求越来越高.在此背景下,该文从政策、标准以及技术 3个方面分析电梯节能增效的必要性;介绍驱动和控制系统、能量回馈装置等电梯能效影响因素;归纳电梯能效测试方法,并引入一则电梯能效测试实例对比测试结果;最后从测试方法标准化和监测产品智能化两方面提出电梯能效测试技术发展方向.研究表明:能效测试是当前国内外电梯能效优化的基础;空载法测试效率更高,需优化载荷系数动态取值方案提高结果准确度;在线监测技术应用比较缺乏.
Abstract
Guided by the"double carbon"goal,affected by factors such as environmental protection,cost reduction and efficiency increase,major elevator production and use enterprises have an increasing demand for elevator energy efficiency testing technology.In this context,this paper analyzes the necessity of elevator energy efficiency and efficiency improvement from three aspects:policy,standard and technology,introduces the influencing factors of elevator energy efficiency such as drive and control system and energy feedback device,summarizes the elevator energy efficiency test method,and introduces an elevator energy efficiency test example to compare the test results,and finally puts forward the development direction of elevator energy efficiency test technology from two aspects:test method standardization and monitoring product intelligence.The results show that the energy efficiency test is the basis of the current energy efficiency optimization of elevators at home and abroad,the no-load method is more efficient,and the dynamic value scheme of the load coefficient needs to be optimized to improve the accuracy of the results,and the application of online monitoring technology is relatively lacking.
