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.
In order to improve the air-conditioning system of air-conditioned buses so that they can provide passengers with high-quality air to meet the ride comfort of passengers, three-dimensional flow numerical simulation of the air ventilation system of air-conditioned train and the air flow inside the cabin Through comparative analysis, we can get an improved design scheme with uniform temperature. In order to make the simulation effect of air conditioning and ventilation system closer to the actual situation, the air moisture content is taken into account in numerical calculation to study the effect of air moisture content on temperature distribution. The two definitions of heat dissipation on the compartment temperature comparative analysis.
