To provide an air conditioner capable of keeping an indoor heat exchanger clean by performing cleaning operation even when a low humidity state continues for a long time.SOLUTION: An air conditioner (1, 11) includes a refrigerant circuit (100), an acquisition unit (9), and a control unit (6, 61). A compressor (21), an outdoor heat exchanger (24), an expansion mechanism (25), and an indoor heat exchanger (32) are annularly connected in the refrigerant circuit. The acquisition unit acquires humidity information related to humidity of air in an air conditioning target space. The control unit executes cleaning operation for cleaning the indoor heat exchanger by controlling the refrigerant circuit and making the indoor heat exchanger function as an evaporator. Further, the control unit executes first cleaning operation or second cleaning operation having a lower ability to clean the indoor heat exchanger than the first cleaning operation as cleaning operation on the basis of the humidity information.SELECTED DRAWING: Figure 3 【課題】湿度の低い状態が長く続く場合であっても、洗浄運転を実行して室内熱交換器を清潔に保つことができる空気調和装置を提案する。【解決手段】空気調和装置（１、１１）は、冷媒回路（１００）と、取得部（９）と、制御部（６、６１）とを備える。冷媒回路は、圧縮機（２１）、室外熱交換器（２４）、膨張機構（２５）、および、室内熱交換器（３２）が環状に接続されている。取得部は、空気調和対象空間の空気の湿度に関する湿度情報を取得する。制御部は、冷媒回路を制御して室内熱交換器を蒸発器として機能させることにより、室内熱交換器を洗浄する洗浄運転を実行する。また、制御部は、湿度情報に基づき、洗浄運転として、第１洗浄運転、および、第１洗浄運転よりも室内熱交換器を洗浄する能力が低い第２洗浄運転のいずれかを実行する。【選択図】図３
