In a car under summer solar radiation, it is well known that the temperature in a car cabin becomes very high and is found to be over 90 degree C on the top of the front dashboard and also air temperature around the driver's seat were over 65 degree C. Thus, ventilation system is one of the effective methods for keeping comfortable thermal environment of a car cabin. In this paper, we conducted experiment and numerical simulations under the conditions that ventilation cold air came into the cabin forcibly from face mode vents and hot air in the cabin was exhausted freely from a rear duct located on rear dashboard, and examined the ventilation effects on inlet mode and at different flow rate. It was clarified that foot mode was the most effective inlet mode for temperature mitigation around driver's seat, and the increase rate of temperature mitigation according to the increase of the ventilation flow rate in foot mode is larger than face mode.
