北京地铁首都机场线采用变频热泵车辆空调应用研究

Research on the application of variable frequency heat pump vehicle air conditioner in Beijing Metro capital airport line

北京地铁首都机场线增购列车采用变频热泵空调系统替换既有线路的传统定频单冷空调系统,对两种方案的节能性,乘坐舒适性及可维护性进行对比分析,分析结果显示变频热泵空调在节能性、舒适性及可维护性等方面优于传统定频空调,更适用于北京首都机场线,为后续轨道列车项目空调系统方案设计提供了依据。

The frequency conversion heat pump air conditioning system is used to replace the traditional fixed frequency single cooling air conditioning system of the existing line in the additional train of Beijing Metro capital airport line.The comparative analysis of the energy saving,riding comfort and maintainability of the two schemes is carried out.The analysis results show that the frequency conversion heat pump air conditioning is superior to the traditional fixed frequency air conditioning in terms of energy saving,comfort and maintainability,which is more suitable for Beijing capital airport line It provides the basis for the air conditioning system design of the subsequent rail train project.
