Elevator energy saving and energy efficiency testing technology
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.
