城市轨道车辆空调回风方案对比研究

Comparative Study on Schemes of Return Air of Air Conditioning for Urban Rail Vehicle

介绍了城市轨道交通车辆空调系统采用座椅底部回风时设置专用回风道和不设置专用回风道2种不同回风方案,通过计算和试验对比研究了2种方案对回风量的影响,并通过分析说明了2种方案对空调系统能耗的影响。分析结果表明,不设置专用回风道的方案回风量较大且更加节能。

Two different return air schemes of setting a special return air duct and not setting a special return air duct when the air conditioning system of urban rail transit vehicles adopts the return air at the bottom of the seat are described.The influence of the two schemes on the return air volume is studied through calculation and test,and the influence of the two schemes on the energy consumption of the air conditioning system is explained through analysis.The analysis results show that the return air volume of the scheme without special return air duct is larger and more energy-saving.
