Abstract
A part of a gas-phase mixed refrigerant compressed by a compressor () is condensed by a first condenser (). Then, the mixed refrigerant is separated by a first gas-liquid separator () into a gas-phase first fluid portion (I) and a liquid-phase second fluid portion (II) which has been condensed into a liquid phase. A part of the gas-phase first fluid portion (I) is further condensed by a second condenser (). Then, the first fluid portion is further separated by a second gas-liquid separator () into a gas-phase third fluid portion (III) and a liquid-phase fourth fluid portion (IV) which has been condensed into a liquid phase. Thereafter, the gas-phase third fluid portion (III) is condensed and then expanded.
