PROBLEM TO BE SOLVED: To cope with complaints on air current, excessive cooling and excessive heating by reducing air capacity from an outlet, while ensuring sufficient flow capacity of an indoor machine.SOLUTION: A bypass duct 6 communicating an entrance side for air to an indoor machine 1 with a discharge side is provided. The bypass duct 6 is provided with a bypass damper 7. A control device 8 is provided for the bypass damper 7. When the average opening &thetas;ave of openings &thetas;1 to &thetas;8 of blowing-out dampers 5-1 to 5-8 is equal to or less than a minimum opening &thetas;min, the control device 8 determines that the whole blowing-out damper 5 is in a narrow state, and opens the bypass damper 7. Consequently, coordination air from the indoor machine 1 flows to the bypass duct 6 side, and sufficient air capacity of the indoor machine 1 is ensured. |
