夏期炎天下駐車時におけるソーラー換気による車室内温度低減: 前席と全席の温度低減に効果のある換気方法の検討

In a car under summer solar radiation, the surface and air temperatures become very high, for example the air temperature around driver's seat was over 65 degree C. Thus, a ventilation system is one of the important methods for keeping comfortable thermal environment. In this study, in order to clarify the effect of temperature reduction in a car cabin by changing ventilation methods, the numerical simulation in a car cabin were conducted. In the case of ventilation flow rate of 100 m³/h, it was found that the effects of air temperature reduction around driver's head with FACE-CLR mode ventilation and on driver's seat with FACE-DP mode ventilation were better than FACE mode ventilation. Moreover it was found that the effects of air temperature reduction around driver's head and around rear seat with FACE-CLR+DP mode ventilation were better than FACE mode ventilation.
