PURPOSE:To provide a proper air flow for each diffuser and to control a blast power to a minimum value, by a method wherein a device is constituted such that a blower is mounted to each passage to each diffuser and a different diffuser is not influenced even if the blowers are individually operated. CONSTITUTION:A coolant circuit 106 is formed with a compressor 101, a condenser 102, a throttle device 301, and a vaporizer 302, and a heat-exchanged air being air-conditioned is guided to a first draft passage 4. A second draft passage 6 is branched from the first draft passage 4, and the air being air- conditioned is blown out of a diffuser part 7 through a bell mouth 502 with the aid of a blower 503 mounted to a diffuser box 5. An on-off damper 5, opened by the suction negative pressure of the blower 503 and closed under gravity, is situated to the diffuser box 5. This enables each blower 503 to individually send a proper air flow to a necessary room without exerting the influence on the diffuser, and permits control of the power of a blower to a minimum value necessary to driving.
