description	To provide an air conditioner capable of: curbing performance deterioration due to aging; detecting a leakage of a coolant without erroneous detection; and improving safety against the leakage of the coolant.SOLUTION: In an air conditioner, an indoor heat exchanger 14 installed in an indoor unit 10, an outdoor heat exchanger installed in an outdoor unit 30, a compressor, and a reducer are connected to each other through coolant piping and a flammable coolant is used as a cooling medium. The air conditioner has a first coolant detection sensor 40 and a second coolant detection sensor which detect a leakage of the coolant. The second coolant detection sensor is provided with: an external air blocking unit 45 which blocks a sensor section of the second coolant detection sensor 41 from external air; and a lifting mechanism 48 which lifts external air blocking with the external air blocking unit 45.SELECTED DRAWING: Figure 2 【課題】本開示は、経年劣化による性能劣化を抑制し、誤検知することなく冷媒漏洩を検出することができ、冷媒漏洩に対する安全性を向上させることのできる空気調和装置を提供する。【解決手段】室内機１０が有する室内熱交換器１４と、室外機３０が有する室外熱交換器、圧縮機、絞り装置とを、冷媒配管を介して接続し、冷媒として可燃性冷媒を用いた空気調和装置において、冷媒の漏洩を検出する第１冷媒検出センサ４０と第２冷媒検出センサとを備え、第２冷媒検出センサには、第２冷媒検出センサ４１のセンサ部への外気を遮断する外気遮断装置４５と、外気遮断装置４５による外気の遮断を解除する解除機構４８と、が設けられている。【選択図】図２
