摘要： With the present invention, the quantity of the refrigerant dissolved in the refrigerating machine oil in a compressor can be correctly determined and the adequacy of the refrigerant quantity in a refrigerant circuit to be judged with high accuracy. An air conditioner (1) includes a refrigerant circuit (10), a refrigerant quantity calculating means, and a refrigerant quantity judging means. The refrigerant circuit (10) is configured by the interconnection of a compressor (21), an outdoor heat exchanger (23), an indoor expansion valve (41, 51), and an indoor heat exchanger (42, 52). The refrigerant quantity calculating means calculates the refrigerant quantity in the refrigerant circuit (10) taking into account a dissolved refrigerant quantity (Mqo) that is the quantity of refrigerant dissolved in the refrigerating machine oil in the compressor, based on an operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit (10). The refrigerant quantity judging means judges the adequacy of the refrigerant quantity in the refrigerant circuit (10) based on the refrigerant quantity calculated by the refrigerant quantity calculating means. In addition, the refrigerant quantity calculating means calculates the dissolved refrigerant quantity (Mqo) based on operation state quantities that include at least the ambient temperature outside the compressor (21).

摘要： The separation between a liquid refrigerant and a lubricant inside an accumulator is prevented, and the amount of the lubricant supplied to a compressor is ensured. As a refrigerant, a refrigerant made of only R32 or a mixed refrigerant containing predetermined mass percent or more of the R32 is used. The refrigerant mixed with a predetermined level or more of the lubricant to prevent the occurrence of the two-layer separation between the liquid refrigerant and the lubricant is supplied to a compressor (104) of an outdoor unit (100). The lubricant separated by an oil separator (106) is returned to the accumulator (105) by an oil return capillary (107) to prevent the occurrence of a two-layer separation area in the accumulator. By the supply of a gas refrigerant containing an appropriate amount of the liquid refrigerant from the accumulator (105) to the compressor (104), the lubricant can be supplied to the compressor (104).
