PROBLEM TO BE SOLVED: To provide a refrigerating machine capable of providing high compressibility and low frequency and capable of improving energy efficiency.SOLUTION: A refrigerating machine comprises: a pressure vibration generating machine 1 which has a first operation chamber 1A formed by a first cylinder 11 and a first piston 12, a second operation chamber 1B formed by a second cylinder 13 and a second piston 14 and a driving part 15 driven in conjugation with the first piston 12 and the second piston 14; first pulse pipe 5 and second pulse pipe 7 of which one end is communicated with a second heat exchanger 4; and a phase adjusting machine 6 which has an inertance piston 63 and a diaphragm part 67. The other end of the second pulse pipe 7 is communicated with the second operation chamber 1B and a phase of pressure vibration flowing into the second operation chamber 1B via the second pulse pipe 7 becomes opposite phase to a phase of pressure vibration of the first operation chamber 1B. |
