| 摘 要： | 应用计算流体力学软件Fluent对某重型货车空调系统和乘员舱中的气流进行数值仿真,其结果与试验对比,相差在5%以内.采用当量温度Teq,i作为评价指标,对乘员舱的热舒适性进行分析.结果表明,由于各风道风量分配不均匀,乘员舱内部气流组织不合理,致使热舒适性较差.对空调系统进行改进,增加前吹面风道风量比例后,乘员舱的热舒适... |

| Abstract: | A numerical simulation on the air flow in air-conditioning system and passenger compartment of a heavy truck is conducted by applying CFD code Fluent and its result is compared to test result with a difference within 5%.Using equivalent temperature as evaluation indicator,the thermal comfort in passenger compartment is analyzed.The results show that,due to the uneven distribution of air flow in various ducts and the unreasonable organization of air flow in passenger compartment,the thermal comfort in passen... |
| Keywords: | heavy truck passenger compartment air-conditioning system computational fluid dynamics thermal comfort |
