NOISE REDUCTION CONSTRUCTION OF COMPRESSOR

摘要

PURPOSE: A noise reduction structure for compressor is provided to lower the temperature of the inner case, maintain optimum pressure, minimize operation noise of the compressor and prevent oil from flowing from the closed container into each gap of the compressor unit by causing convention current of the refrigerant gas within the compressor unit. CONSTITUTION: A noise reduction structure comprises a first silencer(30) mounted at a refrigerant inlet port(15a) of a hermetic compressor unit(10); a pressure compensating and convection generating ventilation hole(12a) formed at the side opposite from the refrigerant inlet port of the hermetic compressor unit; and a second silencer(100) having a refrigerant outlet port(110) and which is mounted at the pressure compensating and convection generating ventilation hole formed to face the inlet side of the second silencer so as to allow the pressure compensation and convection generation to be smoothly performed within the hermetic compressor unit.
