Abstract

A vehicle air-conditioning system adjusts the temperature at an outlet by a combined amount of air flowing through a first bypass passage adjusted by an air mixing door and air flowing through a second bypass passage adjusted by a cool air adjusting door independently of the first bypass. A cool air adjusting door control unit adjusts the opening of the cool air adjusting door so that the temperature detected by a discharge temperature sensor comes closer to a target discharge temperature for precise control of discharge temperature, and also causes the cool air adjusting door to be fully open when the opening of the air mixing door determined by an air mixing door opening setting unit is equal to or smaller than a predetermined degree of opening, so as to maintain a steady amount of air discharged from the outlet.
