静压送风道空气动力性能的试验研究

Test Research of Air Dynamic Performance on Static Pressure Air Supply Duct

介绍了铁路客车空调通风试验台的功能 ,对新型静压送风道进行了性能试验 ,根据试验结果 ,分析了静压送风道的送风均匀性和阻力损失 ,找出了现有客车上已用的静压送风道送风不均匀的原因 ,给出了改变主风道的断面面积。

The air dynamic performances of new type static pressure supply air duct are tested.The uniformity of supply air and resistance loss for static pressure supply air duct are analyzed according to the data tested. The reasons that supply air rate is not uniform by using static pressure air supply duct inside the passenger cars are presented. Some improving measures are given.
