青藏铁路客车弥散供氧条件下需氧量的计算

The Calculation of Oxygen Demand for Diffusion Type of Oxygen Supply System on Qinghai-Tibet Railway Cars

青藏高原高寒缺氧的气候环境要求青藏铁路客车必须具备一定的制氧补氧功能.在现有的国内列车制造水平条件下,弥散供氧作为一种整舱供氧方式,具备一定的优势.在借鉴相关领域科研成果的基础上,对此种方式下的需氧量进行了公式推导和计算,旨在为高原列车供氧方案的确定及供氧系统的设计提供必要的参考.

Considering the climate characteristic of chillness and oxygen shortage on the Tibetan Plateau, the equipments that can produce and replenish oxygen must be installed on Tibetan railway cars. Based on the manufacturing capacity in China at present, the diffusion type is more applicable than others as a way of oxygen supply in the whole cabin. By making reference to the relative research, the oxygen demand of the whole cabin applied the diffusion type can be supplied, as aims at giving a suggestion to the design and establishing oxygen supply system on Tibetan railway cars.
