ABSTRACT OF THE DISCLOSURE An air mixing type automotive air-conditioner is disclosed in which an air fed by a blower is heated to a hot air by a hot water type heater, and a mixture ratio between a cold air flowing through a bypass passage around the heater and the hot air is adjusted by an air mixing door used as an adjustment damper. The air-conditioner comprises an outside temperature sensor for generating a first signal, a room temperature setter for generating a second signal, a room temperature sensor for generating a third signal, a first arithmatic unit for calculating a desired blown air temperature on the basis of the first and second signals, and a second arithmetic unit for calculating and controlling a desired blown air flow on the basis of the second and third signals. The air-conditioner is so controlled as to obtain the blown air temperature most suitable for a thermal load of the air-conditioner.
