PURPOSE: To more reduce the temperature rising in the room of a vehicle due to the aeolotropy of solar radiation while the vehicle parks in the vehicle provided with a ventilation means during parking to discharge the air in the room outside the vehicle using the solar battery provided in the body of the vehicle as a power source while the vehicle parks and an air conditioning means with a main air conditioning duct, which leads outside air to the front section split port, which opens facing to the front seat.
CONSTITUTION: The rear vent duct 31 extended from the main duct 17 connecting an outside air intake port 16 and center vent split port 26a, etc., is forked, and a front section solar radiation sensor for detecting the value of solar radiation in the front section of the room of a vehicle and rear section solar radiation sensor for detecting the value of solar radiation in the rear section of the room of the vehicle are also provided. In the next step, the output from the above front section solar radiation sensor and rear section solar radiation sensor are inputted in a control unit for an air conditioner to control the opening and closing of the rear vent damper 33 installed in the above rear vent duct 31 according to the difference between the outputs from both the sensors.
