摘要
为改善空调客车的空气调节系统,使其能够为乘客提供高品质的空气,从而满足乘客的乘车舒适度,对某空调列车的通风系统及车厢内部的空气流动情况进行了三维流动的数值模拟计算,通过对比分析,得到温度均匀的改进设计方案;为使空调通风系统仿真效果更加趋近实际情况,数值计算中考虑空气含湿量,研究空气含湿量对温度分布的作用;并且对人体散热量两种定义方式对车厢温度的影响进行对比分析.
To supply quality air to passengers by improving air- conditioning system of train carriage, three-dimensional flow numerical simulation on a specificed air-conditioning carriage was investigated. The proposed design which can keep the temperature uniform was concluded through comparing with different programmes. Moreover, the influence of air humidity on tem- perature distribution was studied and the analysis was taken for the impact of two definations of hunman heat release on the temperature of the carriage.
