EXHAUST DUCT STRUCTURE FOR REDUCING NOISE OF COOLING AIR OF COMPRESSOR

PROBLEM TO BE SOLVED: To provide a simple exhaust duct structure for reducing noise of cooling air of a compressor that reduces exhaust noise of cooling air of a package-type compressor.SOLUTION: An exhaust duct has a louver 1 which is fitted to an exhaust port of a package encapsulating the whole compressor. The exhaust duct is disposed at the location of the exhaust port of the package. The cross-section of the louver is formed into a V-shape. The tip of the V-shape is arranged so as to be directed toward the inner side of the package. Exhaust noise is reduced by being divided by the V-shape of each louver 1 and discharged to the atmosphere side.
