PURPOSE:To perform comfortable room heating, by removing hot air in an upper layer especially in winter and suppressing cool air blown out to the foot area, that is, by both changing car room temperature and blowing direction in accordance with an output value of a solar radiation sensor and changing decision level for the existence of solar radiation in accordance with the season. CONSTITUTION:An automobile air-conditioning device performs desired air conditioning operation by blowing conditioned air, obtained by controlling each of an in-out air damper 3, blower 4, cooler 5, air mixing damper 13 and heater 12, to a blow off direction, determined by on-off controlling a defrost damper 14, upper blow-off damper 15 and foot blow-off damper 16. At this time, temperature in a car room and blow-off direction in a car room are controlled by a CPU20 in accordance with each output of an outside air temperature sensor 32, car room temperature sensor 31 and solar radiation sensor 34. Then a decision level of solar radiation used for a decision of the blow-off direction in the car room determined on the basis of outside air temperature is changed in accordance with the season, and an air conditioning condition can be obtained in accordance with the season. |
