To eliminate, appropriately and at a low cost, the separation of liquid refrigerant and refrigerating machine oil into two layers inside an accumulator in an air conditioning apparatus that uses R32 refrigerant. An air conditioning apparatus (10) is equipped with a compressor (20), indoor heat exchangers (50), an outdoor expansion valve (41), an outdoor heat exchanger (30), and an accumulator (70) that is disposed in a suction flow path (27). The accumulator (70) has a casing (71) that forms an inside space for separating the refrigerant into gas refrigerant and liquid refrigerant and accumulating surplus refrigerant, an inlet pipe (72), and an outlet pipe (73). A distal end opening in the inlet pipe (72) is located in a height position separated by a dimension of 0 to 0.3 times the height dimension of the inside space from a bottom of the inside space. |
