摘　　要：列车空调实时负荷不仅随车外气象参数变化,还受到车内人员密度频繁变化的影响。以武汉为例,基于传热学原理,结合武汉地区气象资料,参考已有的客流量实时统计数据,对武汉地铁列车车辆空调全年实时负荷进行了计算分析,以探索武汉地区的列车空调的负荷特性,指导该地区地铁列车热泵空调机组的设计。研究结果表明,武汉地区地铁列车空调制冷季的负荷与采暖季的负荷比值约为2.65,热泵机组应基于制冷需求设计。空调机组大多数时间在部分负荷下运行,满负荷工况较少。新风负荷在负荷占比中超过60%,是地铁列车空调节能重点。The real-time load of the metro air conditioning varies with the meteorological parameters outside the vehicle and changes with the frequently fluctuated passenger density. In the present paper a metro line with known information of the vehicle model heat transfer coefficient and passenger load was assumed in Wuhan. Based on the principles of heat transfer the annual real-time load of the air conditioning in Wuhan Metro was calculated and analyzed according to the meteorological data of Wuhan area and the existing statistical data of real-time passengers to explore the characteristics of the metro air conditioning load and guide the design of metro train heat pump air conditioning unit. The results show that the ratio of accumulated cooling load and accumulated heating load of air-conditioners in Wuhan zone is about 2. 65 and the heat pump unit should be designed based on the cooling requirements. Air conditioners run most of the time under part load. The fresh air load accounted for more than 60% of the total load which is the research priority on air conditioning energy saving of metro.
