The present invention discloses an air conditioning device used for a vehicle. A control device (4) obtains the aperture information of a gas diffusion air valve (25), when the aperture of the gas diffusion air valve (25) is at the heating side, the control device (4) enables the power supply amount supplied to an electric heating device (23) to be greater than the power supply amount supplied to the electric heating device (23) when the aperture of the gas diffusion air valve (25) is at the refrigeration side. The control device is configured to finally determine the power supply amount supplied to the electric heating device (23) according to the aperture of the gas diffusion air valve (25) and the temperature detected by a temperature sensor at the downstream side, so that when the calorific value of the electric heating device changes, even though a heat storage device is not arranged, the temperature for blowing air can be restrained to fall rapidly, and accordingly, the air conditioning device can be miniaturized. |
