Claim:
A ventilation system for a vehicle, comprising: a ventilating unit which performs a ventilation of a passenger compartment using power from a battery of the vehicle while the vehicle is stopped in a vehicle state where the battery is disconnected from a driving source of the vehicle, and no passenger exists in the vehicle; a non-contact temperature sensor which detects infrared rays radiated from a predetermined area of the passenger compartment and detects a surface temperature in the predetermined area by non-contact based on the detected infrared rays, using the power of the battery disconnected from the driving source; ventilation determining means for determining whether the ventilation by the ventilating unit needs to be started based on the surface temperature detected by the non-contact temperature sensor using the power of the battery disconnected from the driving source; and when the determining means determines that the ventilation by the ventilating unit needs to be started, the ventilating unit performs the ventilation using the power of the battery that is disconnected from the driving source of the vehicle.
