太阳辐射对汽车舱内热环境舒适性的影响研究与改善

摘要

太阳辐射是夏季炎热环境下汽车停放在户外汽车舱内热环境最大的热负荷，严重影响车内热环境及乘员热舒适性。运用商用 FLUENT 软件数值模拟太阳辐射对汽车舱内热环境舒适性的影响，仿真分析研究在没有太阳辐射及不同太阳辐射强度情况下车内热环境的变化，确定太阳辐射对车内热环境舒适性影响大。最后通过降低车窗玻璃的透射率来减少太阳辐射进入车内，达到了改善车内热环境舒适性的目的。%Solar radiation is a car parked in a hot environment summer outdoor car cabin thermal environment maximum thermal load,seriously affect the thermal environment of car and occupant thermal comfort.Used the commercial FLUENT software simula-tion of solar radiation impact on the automotive cabin thermal environment comfort,Studied in the absence of solar radiation and different solar radiation intensity of the change of internal environment,determined the solar radiation effect on car internal envi-ronment comfort.Finally,by reducing the transmittance of the window glass to reduce solar radiation into the car,achieved the goal of internal environment to improve the car comfort.
