PURPOSE:To prevent ventilating noise from increasing while ensuring a predetermined amount of blown air, by adjusting a signal of air blowing moderating a change of resistance of air blowing thereafter switching a mode when the mode of air introduction is switched from the mode of small ventilating noise to the mode of large ventilating noise. CONSTITUTION:A means 1 selects an air introducing mode to the mode of large ventilating noise and similarly to the mode of small ventilating noise, while a means 2 blows a flow of introduced air into a car room. Further an air conditioner generates a signal of switching the air introducing mode in a means 3 and a signal of blowing air in a means 4 as well. And a means 5, when the means 3 generates the switching signal from the mode of large ventilating noise to the similar mode of small ventilating noise, adjusts a value of the signal of blowing air generated from the means 4 moderating a change of resistance of blowing air thereafter controlling the means 1 so as to be selected. Then the means 5 again adjusts the value of the signal of blowing air so as to be returned to the value of the signal of blowing air generated from the means 4. |
