Abstract

It is an object of the present invention to provide a refrigerant circuit system in which the volume of a plurality of accumulators provided in series and the size of an oil return hole are appropriately set so as to achieve both the prevention of liquid backflow and the prevention of oil discharge from a compressor caused by deteriorated oil return. The refrigerant circuit system includes: a compressor 9 having a refrigerant suction pipe 20B; a first accumulator 18; and a second accumulator 19, the first accumulator 18 and the second accumulator 19 being provided in series inside the refrigerant suction pipe 20B of the compressor 9 along a refrigerant circulation direction, wherein the first accumulator 18 and the second accumulator 19 are adapted to satisfy V1 > V2 where V1 is a volume of the first accumulator 18 and V2 is a volume of the second accumulator 19, and wherein the first accumulator 18 and the second accumulator 19 are also adapted to satisfy A1 < A2 where A1 is an opening area of a first oil return hole 37 provided in a refrigerant exit pipe 36 of the first accumulator 18 and A2 is an opening area of a second oil return hole 41 provided in a refrigerant exit pipe 40 of the second accumulator 19.
