Zusammenfassung:PROBLEM TO BE SOLVED: To provide an air conditioner capable of suppressing an amount of a refrigerant leaking into a room, even when refrigerant leakage occurs, in the room where an indoor unit of an air conditioner is installed.SOLUTION: An air conditioner 1 includes: an outdoor unit 10 having a compressor 11 for discharging a refrigerant, and a switching valve 12 for switching a direction in which the refrigerant discharged from the compressor 11 flows; an indoor unit 20 having an indoor heat exchanger 21 and an indoor expansion valve 22 capable of controlling a flow rate of the refrigerant to the indoor heat exchanger, and connected to the outdoor unit 10 via refrigerant piping; and a control device 19 for controlling a refrigeration cycle formed by the outdoor unit 10 and the indoor unit 20. The control device 19, when a heating operation is stopped, switches the switching valve 12 for switching the refrigerant flowing direction to a direction at the time of a cooling operation, and brings the indoor expansion valve 22 into a fully closed state. 【課題】 空気調和機の室内機が設置された室内において、冷媒漏洩が発生した場合であっても、室内に漏洩する冷媒の量を抑えることが可能な空気調和機を提供する。【解決手段】 空気調和機1は、冷媒を吐出する圧縮機11と、圧縮機11から吐出された冷媒の流れる方向を切換える切換え弁12とを有する室外機10と、室内熱交換器21と、室内熱交換器への冷媒の流量を制御可能な室内膨張弁22とを有し、冷媒配管を介して室外機10に接続される室内機20と、室外機10および室内機20により形成される冷凍サイクルを制御する制御装置19とを備える。制御装置19は、暖房運転を停止した場合に、切換え弁12を切換えて冷媒の流れる方向を冷房運転時の方向に切換えるとともに、室内膨張弁22を全閉状態にする。【選択図】図1
