To solve the problem in a conventional air conditioner using non-azeotropic refrigerant mixture that there are deterioration of performance due to temperature slip or pressure loss, increase in size of the device, and insufficient safety at the time of leakage in a case of using combustible refrigerant.SOLUTION: An air conditioner comprises a gas-liquid separator 110 provided between a second outdoor heat exchanger 104G and a first outdoor heat exchanger 104L in the middle of an outdoor heat exchanger 104, and an accumulator 113 provided with a liquid gas heat exchanger 114 inside; and stores liquid refrigerant in an outdoor machine 101. Even when combustible refrigerant is used as a high boiling point component of non-azeotropic mixed refrigerant, the air conditioner can reduce a ratio of the combustible refrigerant flowing into an indoor machine 107 to improve safety at the time of leakage and the performance of the device.SELECTED DRAWING: Figure 1 【課題】従来の非共沸混合冷媒を用いた空気調和機では、温度滑りや圧損による性能の低下、装置の大型化、可燃性冷媒を使用した場合は漏洩時の安全性に課題があった。【解決手段】室外熱交換器１０４の途中、第２の室外熱交換器１０４Ｇと第１の室外熱交換器１０４Ｌとの間に設けられた気液分離器１１０、内部に液ガス熱交換器１１４が設けられたアキュームレータ１１３を備え、室外機１０１内に液冷媒を貯留する。非共沸混合冷媒の高沸点成分に可燃性冷媒を用いても室内機１０７に流れる可燃性冷媒の比率を下げて漏洩時の安全性、装置の性能を向上させる。【選択図】図１
