To suppress generation of disproportionation reaction in refrigerant.SOLUTION: An air conditioning device 1 includes: an outdoor unit 2 including a compressor 10; an indoor unit 5; and outdoor unit control means 200. The outdoor unit 2 and the indoor unit 5 are connected by a liquid pipe 6a and a gas pipe 6b. The liquid pipe 6a and the gas pipe 6b are provided with a liquid-side shut-off valve 26a and a gas-side shut-off valve 26b that take at least one second or more for closing operation. The outdoor unit control means 200 controls closing of the liquid-side shut-off valve 26a and the gas-side shut-off valve 26b when a refrigerant leakage sensor 70 detects refrigerant leakage.SELECTED DRAWING: Figure 1 【課題】冷媒に不均化反応が生じることを抑える。【解決手段】空気調和装置１は、圧縮機１０を備えた室外機２と、室内機５と、室外機制御手段２００とを備え、室外機２と室内機５が液管６ａ及びガス管６ｂによって接続され、液管６ａ及びガス管６ｂには、閉じる動作に少なくとも１秒以上かかる液側遮断弁２６ａとガス側遮断弁２６ｂが設けられており、室外機制御手段２００は、冷媒漏洩センサ７０が冷媒漏洩を検知したら液側遮断弁２６ａとガス側遮断弁２６ｂを閉じる制御を行う。【選択図】図１
