郑州地铁车辆定频与变频空调能耗对比研究

Comparative Research on Energy Consumption of Fixed Frequency and Inverter Air Conditioner in Zhengzhou Metro Vehicle

本研究介绍了郑州地铁定频和变频空调机组试验列车配置情况,并对车辆定频和变频空调控制原理进行了阐述。空调系统是与车辆整车性能密切相关的重要部件,夏季能耗占比较大。因此,对比分析了夏季制冷月份定频空调和变频空调的能耗。结果表明:试验条件下,变频空调机组较定频空调机组更加节能,在7—8月节电率约为10%。

This study introduces the configuration of test train of constant frequency and variable frequency air conditioning unit in Zhengzhou metro,and expounds the control principle of vehicle constant frequency and variable frequency air conditioning.Air conditioning system is an important component closely related to the performance of the whole vehicle,and its energy consumption accounts for a large proportion in summer.At the same time,the energy consumption of fixed frequency air conditioning and variable frequency air conditioning in summer refrigeration month is compared.The results show that under the test conditions,the variable frequency air conditioning unit saves energy compared with the constant frequency air conditioning unit,and the power saving rate is about 10% from July to August.
