A refrigerant circuit includes plural gas/liquid separators (1) adapted to separate a two-phase gas-liquid refrigerant (51) into refrigerant vapor (52) and refrigerant liquid (53); a channel switching valve (11) connected to an upstream side of the gas/liquid separators (1) and adapted to switch channels for the two-phase gas-liquid refrigerant (51) by opening and closing; an evaporating heat exchanger (3) adapted to accept inflow of the refrigerant liquid (53) or the two-phase gas-liquid refrigerant (51), the refrigerant liquid (53) being produced as a result of separation by the gas/liquid separators (1); a header (2) installed on an upstream side of the evaporating heat exchanger (3) perpendicularly or at angles to the evaporating heat exchanger (3); a compressor (7) installed on a downstream side of the evaporating heat exchanger (3); and a plurality of bypass routes (6) connected to the respective gas/liquid separators (1) and adapted to allow passage of the refrigerant vapor (52), wherein the refrigerant vapor (52) passing through the plurality of bypass routes (6) and refrigerant vapor (52) passing through the evaporating heat exchanger (3) merge at a first meeting point (±) between the evaporating heat exchanger (3) and the compressor (7). |
