AIR CONDITIONING DEVICE

PROBLEM TO BE SOLVED: To perform a fast judgement that a blower is being driven. SOLUTION: Air in a room R is conditioned by a heat exchanger and a cross flow fan of an indoor device 12 and then the air is blown into a closed space S adjacent to the room R. Blowers 16n1 to 16n3 are connected to power supply lines 18n1 to 18n3. As a power supply for the indoor device 12 is turned on, the power supply lines 18n1 to 18n3 are connected to the power supply and an air blowing of the air in the space S into the room R is started after elapsing of a predetermined time from a time when a switch is turned on. A micro-computer within the indoor device 12 sets as a threshold value a value larger by a predetermined value than a driving current detected by a sensing means in the indoor device 12 from a time in which the power supply lines 18n1 to 18n3 are connected to the power supply to an elapsing of the predetermined time, judges whether or not the present driving current detected by the sensing means is more than the threshold value and in the case that it judges that the driving current is more than the threshold value and further judges that the driving current is more than the threshold value, the micro-computer controls a rotating speed of the cross-flow fan in such a way that an air blowing amount into the closed space S may be increased.
