【摘要】 提出了汽车停启过程车内温度变化的理论分析模型,得到了车内气温随时间变化的分析解。理论分析结果表明,汽车在停—启过程中,车内气温随时间呈指数规律变化,当时间足够长时,车内温度趋于稳定。首次提出了空调汽车的特征温度及温度响应指数的概念。理论分析表达式不仅从物理意义上清晰地揭示了汽车停—启过程中车内温度变化规律,而且与实验结果吻合较好。该理论分析结果对综合考察汽车整体结构及空调系统设计的优劣、改善汽车舒适性及降低启动过程的耗油量具有指导意义。更多还原

【Abstract】 The theoretical analysis model for the indoor air temperature characteristic of car in parking and starting process is put forward. The analytical solution for the indoor air temperature variation with time is obtained. The theoretical analysis result shows that, in parking and starting process, the indoor air temperature changes as an exponential function of time, and approaches to a constant. The theoretical formula not only theoretically reveals the physical laws of the indoor air temperature variation of car, but also is validated by experiment.更多还原
