PURPOSE:To prevent uncomfortableness, by compensating the degree of opening of an air mix door to increase the proportion of mixed warm air if the temperature of external air is lower than that of internal air but increase the proportion of mixed cool air if the temperature of external air is not lower than that of internal air, to prevent the change in the temperature of the riding room of a vehicle. CONSTITUTION:A set temperature 16, the temperature 17 of internal air, the temperature 18 of external air, the quantity 19 of insolation and the speed 20 of wind are entered into a controller 15 to regulate an internal and external air changeover door 3, a blower 5 and an air mix door 8. When the wind speed is not lower than a prescribed level, for example, 10m/s, the internal and the external air temperatures 17, 18 are compared with each other. If the difference between the compared temperatures is not less than a prescribed value, for example, 5 deg.C and the external air temperature 18 is lower than the internal air temperature 17, an aimed value for the air mix door 8 is compensated to increase the proportion of warm air. If the difference is not less than 5 deg.C and the internal air temperature is lower than the external air temperature, the aimed value for the air mix door is compensated to increase the proportion of cool air. The degree of opening of the air mix door 8 is thus controlled to prevent the temperature of the riding room of a vehicle from changing depending on the speed of introduced air, to maintain comfortableness. |
