Abstract
An air conditioning device comprises a refrigerant compression cycle having an electrically driven compressor, an electric motor for driving the compressor, frequency changing means for changing the frequency of a.c. power to be applied to the motor, an outlet port for blowing off conditioned air, flowing direction changing means for changing the flowing direction of the conditioned air from the outlet port, a switch which is actuated by a user when he desires to allow the conditioned air to hit himself directly, and control means for controlling the frequency changing means and the flowing direction changing means, wherein when the switch is actuated during room cooling operation, the control means outputs to the flowing direction changing means a signal for directing the conditioned air from the outlet port in a downward flowing direction.
