To provide a refrigeration cycle device capable of preventing a metal member of a refrigeration circuit from corroding at low cost.SOLUTION: An air conditioner 1 comprises a refrigerant circuit 1a in which a mixed refrigerant containing at least 20 weight% of a low GWP refrigerant containing at least one of a refrigerant having a carbon-carbon bond other than a single bond as a bond between carbon atoms, a refrigerant having a single bond of carbon and a halogen group element having an atomic weight exceeding 10 times that of carbon, and a refrigerant having an ether bond, and refrigeration oil circulate. A metal member forming the refrigerant circuit 1a is a material corresponding to an oil amount ratio which is a value obtained by dividing the mass of the refrigerating machine oil by the sum of the mass of the refrigerating machine oil and the mass of the refrigerant. This makes it possible to cope with a model in which an acid has a large effect of lowering the reliability of the air conditioner 1.SELECTED DRAWING: Figure 1 【課題】冷媒回路の金属部材の腐食を低コストで防止する冷凍サイクル装置を提供する。【解決手段】空気調和装置１は、炭素原子間の結合として単結合以外の炭素間結合を持つ冷媒、炭素の１０倍を超えた原子量のハロゲン族元素と炭素との単結合を持つ冷媒、エーテル結合を持つ冷媒、のうち、少なくとも一つを含む低ＧＷＰ冷媒を２０重量％以上含む混合冷媒と、冷凍機油が内部を循環する冷媒回路１ａを備える。冷媒回路１ａを形成する金属部材は、冷凍機油の質量を、当該冷凍機油の質量と前記冷媒の質量の和で除した値である油量比率に応じた素材である。これにより、酸が空気調和装置１の信頼性を低下させる影響が大きくなる機種に対して対応できる。【選択図】図１
