PURPOSE:To forcedly carry internal air of a car outside of it by providing a small electric fan at a part near an air discharge outlet and disposing a plurality of solar batteries on front and rear window glasses, thereby turning and driving the electric fan by the energy of this solar battery. CONSTITUTION:A plurality of solar batteries 7 are disposed on the internal faces of window glass such as a front and a rear window glass 8 and 9 in such phases that at least one of the solar batteries can receive the sunlight regardless of radiation angle. In the good weather, the solar batteries 7 convert solar energy to electric power, which turns and drives an electric fan 6 to discharge internal air of a car outside from discharge port 5. On the contrary, fresh open air can be induced into the car room from a naturally ventilating supply port 2. By circulating open air inside the room as above, temperature of room air may be prevented from being excessively increased when the car is parked outdoors in the summer. |
