Abstract
(EN)
One end of first piping (41) on a suction side is connected to a suction pipe (32) of a compressor (30). The other end of the first piping (41) is connected to second piping (42). The spring constant k1 of the first piping (41) and the spring constant k2 of the second piping (42) satisfy a condition of 100≤k2/k1.
(FR)
Selon l'invention, une extrémité d'une première tuyauterie (41) côté aspiration est raccordée à un tuyau d'aspiration (32) d'un compresseur (30). L'autre extrémité de la première tuyauterie (41) est raccordée à une seconde tuyauterie (42). La constante d'élasticité k1 de la première tuyauterie (41) et la constante d'élasticité k2 de la seconde tuyauterie (42) satisfont à la condition 100≤k2/k1.
(JA)
圧縮機(30)の吸入管(32)には、吸入側の第1配管(41)の一端部が接続されている。第1配管(41)の他端部には、第2配管(42)が接続されている。第1配管(41)のばね定数k1、第2配管(42)のばね定数k2が、100≦k2/k1という条件を満たしている。
