空调汽车停-启时车内温变特性的理论分析与实验检验

在实验的基础上提出了汽车停一启时影响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，汽车在停一启过程中，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。理论分析表达式不仅物理意义清晰地揭示了汽车停一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。

Theoretical and Experimental Study on Air TemperatureCharacteristics inside a Car during Parking and Starting

This paper puts forward a theoretical analysis model for air temperature characteristic inside a car during parking and starting. The analysis solution shows that the variation of air temperature inside a car with time follows index number law and becomes stable when the time is long enough. The theoretical analysis not only reveals the law of air temperature variation in clear physical meaning, but also coincides well with the experimental results.
