PURPOSE:To reduce a force for rotating a damper and enable a driving machine to have a small size by a method wherein a discharging passage damper is cooperatively arranged at the driving machine through a connector, and the discharging passage damper and a bypass damper are cooperatively arranged through a cooperating link. CONSTITUTION:In case of performing an air conditioning and aeration by using a heat exchanger 10, a driving machine 16 is turned OFF, a discharging passage damper 34 is rotated by a resilient body 38, an opening is released and at the same time a bypass damper 36 is rotated by a cooperating link 37, an opening 33 is closed, each of blowers 8 and 9 is operated, thereby interior air is sucked from an interior suction port 2 into an interior suction chamber 29 through a duct. During an intermediate season requiring no cooling or heating, the driving unit 16 is operated and the discharging passage damper 34 is rotated and simultaneously with this rotating operation, the bypass damper 36 is rotated by the cooperating link 37, the opening is overlapped on the discharging passage damper 36 to close it. The opening 33 is released to open and each of the blowers 8 and 9 is operated to cause the interior air to be sucked from the interior suction port 2 to the interior suction port 29 through a duct. |
