PURPOSE:To reduce vibration and noise easily at low cost by setting the difference in length between two exhaust pipeline parts connecting two compressors made into contact to each other in parallel with an expansion type silencer into an odd magnification of the half-wave length in the pulsating wave of the compressors. CONSTITUTION:In a refrigerating circuit, an expansion type silencer 4, a flocculator 2, a throttling device 3, a cooler 4, and two compressors 1a, 1b connected in parallel to each other are connected to each pipeline 5a-5d, 6-8 to mutually form a circuit. In the above constitution, the difference in length of two exhaust pipelines 5a, 5b connecting the compressors 1a, 1b with the expansion type silencer 5, respectively, is set to an odd magnification of the half-wave length in the pulsating wave of each compressor 1a, 1b. Namely, one pipeline 5a is set to the other pipeline 5b in such a manner that the difference between the respective lengths is equal to the half-wave length in the pulsating wave of a coolant gas exhausted from each compressor 1a, 1b.
