The case 110 is formed in an almost rectangular parallelepiped shape so that an accommodation space is provided therein, and is usually embedded in the ceiling so that the bottom is exposed to the interior. A plurality of suction ports 112 are formed at each side of the bottom surface of the case 110 to suck air, and a discharge hole 114 is formed at the central area to discharge the air inside the case 110. have.

Inside the case 110, a heat exchanger 121 is formed to have a circular ring shape, and the inside of the heat exchanger 121 sucks air through the inlet 112 and passes through the heat exchanger 121. A blowing fan 125 implemented in the form of an axial fan is installed to discharge the heat-exchanged air to the outside. In the center of the bottom of the case 110 is formed a guide portion 115 for guiding the air having an arc-shaped cross section, the discharge port 114 is formed in the central region of the guide portion 115 so that air can be discharged have.

On the other hand, the discharge port 114 has a tubular shape so that the air flows therein is formed at the lower end of the rotary support 117 for rotatably supporting the rotary air supply unit 131. A plurality of discharge holes 118 are formed at a lower end of the rotation support part 117 so as to discharge air and are spaced apart along the circumferential direction, and around the discharge hole 118, a rotary air supply unit ( A bearing 119 is provided to rotatably support the 131.
