摘要:
乘用车舱内的热环境对驾驶员和乘客的身心状态有明显影响,而降温是提升夏季乘用车舱体内热舒适性的主要手段。文章以家用轿车为实验研究用车,采用现场测试和数值模拟相结合的方法,对比研究了开窗降温和空调制冷两种降温方式对汽车乘员舱内部热环境和热舒适性的影响。结果表明:采用开窗降温方式,舱内环境平均温降约为8 ℃,降温过程前20 min舱内温度变化较为明显;采用空调降温方式,舱内环境平均温降约为13 ℃,降温整体效果好于开窗降温;利用计算流体力学软件模拟的空调制冷结果与实验数据吻合较好,说明使用空调进行降温效果明显。
Abstract:
The thermal environment in the passenger car cabin has a significant impact on the physical and mental state of the driver and passengers. Cooling is the main means to improve the thermal comfort of passenger car cabin in summer. In order to find a way to reduce the thermal shock of passengers caused by the change of thermal environment in the cabin after a long-time parking, the thermal comfort of passenger compartment has been studied by means of experimental test and numerical simulation in this paper. The effects of two cooling modes, window cooling and air conditioning cooling, on the thermal environment and thermal comfort of the passenger compartment are studied. The results show that the average temperature drop of cabin air is about 8 ℃ when the window was opened to cool down, and the temperature change significantly in the first 20min of the cooling process. When air conditioning method was conducted, the average temperature drop of air in the cabin is about 13 ℃, so the overall cooling effect of which is better than that of window cooling. The simulation results of CFD software are in good agreement with the experimental data, and that further proved that the cooling effect of air conditioning method is more effective than that of window cooling.
