Energy consumption analysis of train air conditioners based on measured data

Based on Guangzhou Underground Railway Line 6, during July and August, monitors the power consumption of train air conditioners by installing ammeters in the electrical box at the bottom of a train. After analysing the data, finds that the power consumption of train air conditioners accounts for about 86% of the power consumption of train auxiliary equipment and about 21% of the total power consumption of the train. The ratio of the power consumption of train air conditioners to the traction power consumption is about 2∶8, and the average power consumption per unit distance of train air conditioners is 2.90 kWh/km. In the short-term, the track heat removal system has little effect on the power consumption of train air conditioners.
