1. A system for controlling an internal temperature of a vehicle when an engine of the vehicle is turned off, the system comprising:
a temperature sensor configured to measure the internal temperature of the vehicle;
a first blower configured to discharge cooled air when an electric power is supplied to the first blower;
a battery; and
a control unit electrically connected to the temperature sensor and the first blower and configured to receive a signal of the internal temperature from the temperature sensor and to operate the first blower,
wherein the control unit electrically connected to the battery is configured to control an electric power of the battery to be applied to the first blower when the controller concludes that the internal temperature of the vehicle is equal to or greater than a predetermined reference temperature in a state where the engine of the vehicle is turned off,
wherein the first blower is provided with a Peltier element configured to cool and heat first and second surfaces of the Peltier element, respectively, by a Peltier effect,
wherein the air cooled by the Peltier element is supplied to an interior of the vehicle,
wherein air heated by the Peltier element is discharged to an outside of the vehicle, and
wherein the system further includes:
a front vent through which air flows into the interior of the vehicle from the outside;
a vent grill configured to discharge the air in the vehicle to the outside; and
an exhaust duct including a rear end portion connected to the vent grill to discharge the air in the interior of the vehicle and the air heated by the Peltier element to the outside of the vehicle.
