PROBLEM TO BE SOLVED: To provide a refrigeration cycle capable of efficiently evacuating the inside in charging a refrigerant, and preventing increase of the number of components and work man-hour.SOLUTION: An intermediate heat exchanger 8 of a refrigeration cycle has a double pipe system including an outer pipe 23 and an inner pipe 24 disposed inside of the outer pipe 23 at an interval, a clearance gap between the outer pipe 23 and the inner pipe 24 serves as a high temperature-side refrigerant passage 11, and the inside of the inner pipe 24 serves as a low temperature-side refrigerant passage 12. The intermediate heat exchanger 8 is provided with a valve device 22 composed of: a valve mounting body 30 having a first passage 31 communicated to the high temperature-side refrigerant passage 11, and a second passage 32 communicated with the low temperature-side refrigerant passage 12, and fixed to the intermediate heat exchanger 8; and charge valves 21, 22 respectively disposed in the first and second passages 31, 32 of the valve mounting body 30. |
