摘要
缺氧问题是青藏铁路建设中的一大难题。如何供氧、如何保证青藏铁路客车内人员的舒适性是当前研究的热点。众多研究者都提出了自己的看法,但都不是很理想。本文提出了一种全新风逆升压空气循环制冷增压系统,并针对青藏铁路沿线的特殊的气候条件,研究了该系统在设计工况下和在不同海拔高度下的性能表现。结果表明:该系统不仅能实现增压供氧,而且能同时制冷,能很好的保证列车内人员的舒适性。
h is a big obstacle for the anoxic problem in building of Qingzang railway.It is the focus of how to feed oxygen and howto assure the comfort of passengers. So there are various ideas about this, but they are not very ideal. In this work, a negative-superchange circuit of air cycle refrigeration and supercharge system has been developed, and the performance of the system has been researched against the design condition and altitude for the particular climate of the line of Qingzang railway.The analysis shows that this system not only be able to supercharge and feed oxygen , but also be able to refrigerate, it can give a comfortable place for the passengers.
