PROBLEM TO BE SOLVED: To improve performance of a first evaporator 40 by reducing the level of dryness of a cooling medium flowing into the first evaporator 40 from an ejector 30. SOLUTION: A cooling medium low in the level of dryness is separated from a cooling medium high in the level of dryness by arranging a gas-liquid separator 70 between the ejector 30 and the first evaporator part 40; and the cooling medium low in the level of dryness is made to flow through the first evaporator part 40 to convert it to the cooling medium high in the level of dryness, thereafter merged into the cooling medium high in the level of dryness having flowed out from the gas-liquid separator 70 by equalizing the pressure thereof, and sucked into a compressor 10. Since a liquid cooling medium or the cooling medium low in the level of dryness is thus made to flow into the first evaporator part 40, a distribution property of the cooling medium is improved, cooling medium pressure loss in the evaporator is reduced to improve the performance of the first evaporator part 40, and the performance improvement of a system can be eventually provided.
