  • the temperature difference in the wall or the like is calculated rather than the temperature difference in the floor surface temperature, and the arrival position is detected.
  • the target airflow position does not have to be determined based on the position of the person detected by the human body detection unit 102 or the like.
  • the position of an object other than a person may be detected, and the target airflow position may be determined based on the detected position or the like.

  • the opening degree is adjusted based on an instruction from the control device 100 or the like.
  • the indoor heat exchanger 17 performs heat exchange between air to be air-conditioned and a refrigerant. During heating operation, it functions as a condenser and condenses and liquefies the refrigerant. Moreover, it functions as an evaporator during cooling operation, evaporating and evaporating the refrigerant.
  • the air conditioner As described above, by configuring the air conditioner using the indoor unit 10 described in the embodiments so far, for example, in the room serving as the air-conditioning target space, the air is more accurately directed toward the target airflow position. Since harmonious air can be sent, comfortable and energy-saving operation can be realized.
