摘要(Abstract):

介绍了青藏铁路 (格拉段 )沿线地区的气象条件以国家标准对铁道客车车厢内的二氧化碳允许浓度的相应规定 ,人体的二氧化碳排出率和活动状态的关系 ,铁道客车的新风量的确定及其对于电加热器耗能的影响。考虑到空气的密度随海拔高度和气温而变化 ,而且人体的二氧化碳排出率和活动状态有关 ,设计了按照车厢内的二氧化碳浓度、海拔高度、车内外气温和乘客的活动状态来自动地调节新风量和电加热器的功率的方案 ,该方案可大大地节约电加热器的能耗
The environmental condition of the area along Qinghai Tibet railway,the permitted dioxide concentration in the railway passenger cars specified,the relationship between dioxide production rate and physical activity of human beings,and the calculation of the fresh air rate with its effect on the power consumption of the electric heater were introduced.Air density changes with the altitude and temperature variations. CO 2 production rate of the passengers is related to their physical activity.So energy can be greatly saved if the fresh air rate and power consumption of the electric heaters are automatically regulated according to the CO 2 concentration in the passenger car cabin,altitude,temperatures inside and outside the cabin, and physical activity of the passengers.
