地铁车厢空调气流组织评价

摘要

Based on the turbulence model of air flow,air diffusion in a subway passenger car was simulated.Air diffusion performance index,uniformity coefficient and energy utilization coefficient were used to evaluate the thermal comfort and energy conservation of air diffusion.The result indicated that the evaluations through these three indexes were accurate.Therefore,air diffusion performance index,uniformity coefficient and energy utilization coefficient can be applied in design and optimization of air conditioning system in a subway passenger car.%基于空气运动的湍流流动方程,对地铁车厢内的空调气流组织进行仿真,并利用空气分布特性指标、不均匀系数以及能量利用系数评价空调气流组织的舒适性和节能性。结果表明通过这三个指标能合理地评价气流组织分布性能。因此,空气分布特性指标、不均匀系数以及能量利用系数可以作为有效的评价指标应用于地铁车厢空调的设计和优化中。
