PURPOSE:To heat a room efficiently immediately after the starting of operation of the air conditioner by a method wherein room temperature and the blow-off air temperature of the air conditioner are detected to operate a rotating number controlable fan motor in conjunction with an airflow direction changing plate, whose position is changed by a small motor, and control the blow-off angle, ventilating air amount and blow-off speed of the air conditioner. CONSTITUTION:An air conditioner is provided with a sensor 10, detecting the temperature Td of blow-off airflow c, the small motor 11, controlling the angle R of the air direction changing plate 12 and the height Dh of a blow-off port, and a control circuit 13, connected with a room temperature sensor 7, the blow-off air temperature sensor 10, the small motor 11, the rotating number controlable fan motor 14 and the like and controlling them cooperatingly. Upon the starting of operation, the blow-off angle theta is enlarged and blow-off speed V is decreased to increase the blow-off temperature Td immediately and when the blow-off temperature Td has become high, the height Dh of the blow-off port is decreased to increase the blow-off speed V. Subsequently, the blow- off angle theta is decreased and when a room temperature Ti is increased further, ventilation is controlled by increasing the airflow amount M as well as the height Dh of the blow-off port and the like.
