PURPOSE:To prevent a so-called a shortcut in which part of hot air is entangled with a flow of the air in a room to be sucked to a suction port and sucked again when the hot air is blown off downward from an air outlet. CONSTITUTION:Air outlets 21 are disposed at centers of side edges of a square- shaped ceiling panel 20, and suction ports 22 are disposed at the corners of the panel 20. |
