Description

  The present invention relates to an altitude installation type air conditioner, and more particularly to an altitude installation type air conditioner that can improve the blown airflow. Here, the high place installation type air conditioner is an air conditioner that is installed and used at a high place such as a ceiling embedded type air conditioner or a ceiling suspended type air conditioner.

  As an altitude installation type air conditioner, a ceiling-embedded air conditioner is well known. In the case of this ceiling-embedded air conditioner, an air conditioner body that is suspended and supported from the back of the ceiling in an opening formed in the ceiling and includes a blower and a heat exchanger inside, and a lower surface of the air conditioner body And a rectangular decorative panel that is attached to the side and covers the ceiling opening. The decorative panel is formed with an air suction port located in the center and four air outlets located at positions along the four sides of the decorative panel so as to surround the air suction port. That is, in the conventional air conditioner, the indoor air sucked from the air suction port formed in the central portion of the decorative panel is cooled or heated in the process of passing through the heat exchanger in the air conditioner body, and is conditioned. The air is blown into the room from four air outlets formed at the side edge of the decorative panel (see Patent Document 1).
