PURPOSE:To quicken the rise-up of heating without providing a human body with cool air by a method wherein the direction of blow-off warm-air is permitted to be deflected to up-and- down or left-and-right directions while a compressor is driven in high revolution and blow-off air is blown horizontally in case blow-off air temperature is lower than a set temperature when a set time of elapse has elapsed but ventilating air is blown off so as to be concentrated to the lower part of a room when the set temperature has been achieved. CONSTITUTION:The blow-off port of an indoor unit is provided with a vane 1, deflecting blow-off air to up-and-down directions, and left-and-right deflecting vanes 5a, 5b, deflecting the blow-off air so as to be distributed to left-and-right directions. When ventilating air temperature has arrived at a predetermined value, the revolution of a compressor is reduced and the vanes 1, 5a, 5b are deflected so as to concentrate the blow-off air to the lower central part of a room. When the ventilating air temperature is lower than the set temperature (t1) after a set time T1 has elapsed the revolving number of a compressor is increased and the below-off air is distributed to the lower left-and-right parts of the room to heat a space near the walls of the room. When the temperature becomes high, the revolving number of the compressor is reduced while the rotating number of a fan is increased and the blow-off air is concentrated to the lower central part of the room.
