PROBLEM TO BE SOLVED: To ventilate in a room even without opening a window by opening a channel side end of ventilating piping to a downstream side of a supply fan at the channel. SOLUTION: A channel for guiding a flow of the air induced by a supply fan 14 is formed together with stabilizers 42 mounted at a rear panel 10 and a front panel 20. A grill 30 is mounted in the forward side of the panel 20, and many suction holes 32 for sucking indoor air are formed at the panel 10, the panel 20 and an upstream side of a heat exchanger of the grill 30. A ventilating means 50 is constituted of ventilating piping 52 coupled to the channel through a wall 60 for partitioning into the indoor and the outdoor, and an opening/closing plate 54 for selectively opening or closing the channel side end of the piping 52. The channel side end of the piping 52 is coupled to a downstream side of the exchanger 12 of the panel 10, and the side end is extended out of room through holes 62 formed at the wall 60. |
