The air passage area of ​​the air outlet end is smaller than that of the air inlet end. The motor and the fan are located at the rear end of the air outlet section 102. Driven by the motor, the fan draws in air from the outside, passes through the vortex generator 12 and the rectifier plate, and is blown out from the air outlet section 102. This invention, by controlling the vortex generator to stably generate vortices, delivers the air blown out by the indoor unit 1 to a designated, farther location. When the user selects the vortex ring mode, the vortex ring generator opens and closes the air inlet end within a preset time or reciprocates within a preset time to generate a vortex ring in the vortex ring generator 12. When the user selects the normal air conditioning mode, the vortex ring generator 12 keeps the air inlet end of the air outlet section 102 open. Under the action of the fan, the indoor air passes through the heat exchanger 16 and reaches the vortex ring generator 12. The vortex ring generator 12 opens and closes within a certain time. The air passes through the rectifier plate, which applies axial disturbance to the gas inside the front end of the air outlet section 102, thereby causing the airflow blown out from the air outlet end of the variable cross-section air outlet section 102 to form a vortex ring. Cold air / hot air / humid air are delivered to the far end of the room in a ring pattern.
