Abstract
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).
