PURPOSE:To improve comfortableness ensuring a clear feeling of blown air speed without generating a blower noise by controlling a blown air proportion of conditioned air for two or more blow outlets to be timely changed being based on a thermal load condition in a car room. CONSTITUTION:An air conditioner main unit 20 is constituted of a blower unit 21, cooling unit 22 and a heater unit 23. In this constitution, each right and left branch duct 4R, 4L respectively communicates with an end part of a ventilator duct 34 arranged in the heater unit 23, while an air distributing door 5, serving as the blown air quantity proportion control means, is pivotally supported to these communication parts. While a controller 41 respectively inputs each detection signal from an outside air temperature sensor 42, room temperature sensor 43, room temperature setter 44 and a solar radiation quantity sensor 45 which detect a thermal load condition n a car room. And controlling the air distributing door 5 being based on the thermal load condition in the car room, a proportion of blown air quantity is timely changed. |
