<p>An air conditioner unit for a vehicle capable of discharging an air with a relatively high temperature in a cabin to the outside of the cabin by utilizing an outside air inlet after taking in an air conditioner unit and circulating in an air flow passage, and then recirculating the air to an intake part as a part of a mode selection in the intake part. In the intake part (2), inside and outside air inlets (21) and (22) leading the air on the inside and outside of the cabin therein in normal operation and a ventilation inlet (29) leading the air inside the cabin therein in ventilation are opened thereto, and an inside and outside air switching door (25) adjusting the ratio of the openings of the inlets (21), (22), and (29) is stored therein. In an air conditioner unit (3), a branch passage (35) is branched from a blowout passage (24) near an opening part (14) for defrost blowing, and the other end of the branch passage (35) is opened to an passage (26) continued to the outside air inlet. In the inside and outside air switching door (25), the ventilation inlet (29) is opened from the inside of the cabin into the intake part (2) in ventilation to take in the air inside the cabin. A switching door (19) capable of regulating the amount of the air fed to the branch passage (35) is disposed at a branch portion between the blowout passage (24) and the branch passage (35).</p> |
