【摘要】 乘员舱内部热环境直接影响着驾驶人和乘客的心理状态,对乘员舱热舒适性的研究已成为汽车行业的一个重要方向。本文采用计算流体力学方法,研究了空调风道不同风量分配下乘员舱内的环境分布和热舒适性,使用PMV方法进行评价,仿真过程中通过空调降温性能实验验证了仿真模型的准确性。结果表明,风量分配对乘员舱热舒适性有很大的影响,当风量比η为1.2时,乘员舱整体的热舒适性优于其他工况。更多还原

【Abstract】 The thermal environment inside a passenger compartment directly affects psychological state of driver and passengers.The research on thermal comfort has become an important direction in the automotive industry.In this paper,the computational fluid dynamics method was used to study the environment and thermal comfort of the passenger compartment under different air volume distribution,and the PMV method was used to evaluate it.In the simulation process,the accuracy of the simulation model was verified by air conditioning cooling performance experiment.The results show that air volume distribution had a great influence on the thermal comfort of passenger compartment.When air volume ratio was 1.2,the thermal comfort of passenger compartment was better than other conditions.更多还原
