Abstract: PURPOSE:To make air flow distribution of supplying air in a room uniform and to eliminate noise in the room by connecting the base end side of a passage block to the diffuser of an air supply fan, and bending the end side in the same direction of the rotary shaft of the fan to provide a passage continued to an indoor air supply port. CONSTITUTION:A sound absorbing material is mainly integrally formed between the diffuser of an air supply fan 9 and an indoor air supply port 2, and a passage block 12 formed with a passage 11 is mounted on the inner surface. The passage 11 is bent from a connection to a diffuser of a fan housing 92 toward the end side, the end side is so bent as to become the same direction as the rotary shaft of a fan rotor 91 to be continued to the port 2. When the diffused air from the diffuser of the housing 92 by the fan 9 passes the bent passage 11 of the block 12, the air is received by its resistance to be straightened by its wind power. Accordingly, a drift generated at the periphery of the diffuser is cancelled to make the air flow distribution from the port 2 into the room uniform, thereby obtaining a large silencing effect.
