PROBLEM TO BE SOLVED: To provide a pipe capable of suppressing a vibration in a curved portion with a simple configuration.SOLUTION: A curved portion is provided in a pipe 50. The curved portion is disposed at a position apart from a condenser 32 by an integer multiple of a half-wavelength of the pulsation of a compressor 31. A portion running into the condenser 32 from the pipe 50 is a little pulsation region, that is, a pulsation node. The position apart from the pulsation node by an integer multiple of the half-wavelength of the pulsation is similarly a pulsation node. By providing the curved portion in such a pulsation node portion, the pulsation striking on a wall surface of the curved portion is reduced since the portion is a low vibration region. It is, therefore, possible to suppress the generation of vibration of the pipe 50 in the curved portion.SELECTED DRAWING: Figure 3 |
