PURPOSE:To enable more proper air conditioning control by controlling each of the temp. and branching quantity of blast on the upper and lower parts in a vehicle room to the optimum in accordance with a head-cooling and foot- warming principle. CONSTITUTION:In an air duct 1 which is opened to the upper and lower parts in a vehicle room, blast is carried out to each of the upper and lower opening parts 1a, 1b by a blast means 2. In this case, the temperatures of the upper and lower blasts are controlled by a temp. control means 5 so as to be their respective target values based on the detected results from upper and lower temp. detecting means 3, 4 provided on the upper and lower parts of the vehicle room respectively. And, the upper and lower blasts are branched and controlled to be two types of target branching quantities by a branching control means 6 in accordance with difference between the temp. detected by a lower temp. detecting means and the temp. detected by an upper temp. detecting means 3. Thereby, the temp. and branching quantities of blasts on the upper and lower parts in a vehicle room can be controlled to the optimum in accordance with a head-cooling and foot-warming principle. |
