实验研究了炎热环境下汽车停放时车内温度变化规律及降低车内温度的各种措施。实验表明,停车时车内某些表面(如仪表台)温度高达70℃(可能会使气体打火机爆炸);车内空气温度可高达55℃以上,离开时若将婴儿或其它动物置于车上是危险的,该结果有利于增强驾乘人员安全防范意识。实验探索的各种有效降低车内温度的方法,给驾乘人员以改善乘车环境,同时降低汽车重新启动过程耗油量的启示。 Experiments were carried out to study the law of temperature change in the car parked in hot environment and various measures to reduce the temperature inside the car. Experiments show that when parking some surfaces (such as dashboard) temperature up to 70 ℃ (which may make the gas lighter explosion); the car air temperature can be as high as 55 ℃ above, leave the baby or other animals if the car Is dangerous, the result is conducive to enhancing occupants safety awareness. Experiments to explore a variety of effective ways to reduce the temperature inside the car, to the occupants to improve the riding environment, while reducing fuel consumption enlightenment car restart process.
