A vehicle air-conditioning apparatus includes emergency dampers switchable between opening states for opening emergency vents and closing states for closing emergency vents. A control device switches the emergency dampers from the closing states to the opening states while keeping an indoor fan operating, when determining that refrigerant is leaked from a refrigerant circuit on the basis of results of detection by refrigerant leakage detectors. An indoor unit chamber includes supply air guiding sub-chambers for guiding the internal air delivered by the indoor fan to supply openings. The emergency vents are included in the supply air guiding sub-chambers. The indoor fan forms flows of the internal air with the air pressures in the supply air guiding sub-chambers being higher than the atmospheric pressure.
