Abstract: A refrigerating cycle system and a refrigerator having the same are provided. The refrigerating cycle system includes a condenser, a first capillary tube unit configured to receive refrigerant that has passed through the condensing unit, a gas-liquid separating unit configured to separate the refrigerant that has passed through the first capillary tube unit into liquid refrigerant and gaseous refrigerant, a first evaporator unit configured to receive the liquid refrigerant separated at the gas-liquid separating unit, a liquid refrigerant removal unit configured to receive the gaseous refrigerant separated at the gas-liquid separating unit and a first compressor unit configured to receive the gaseous refrigerant from the liquid refrigerant removal unit. The liquid refrigerant removal unit prevents supplying the separated liquid refrigerant to the first compressor unit.
