An air conditioner (11) includes a main unit (25) having an enclosure defining an air outlet. The enclosure contains a heat exchanger (14) generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units (26) are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.
