Definitions

  • the present invention relates to a suction muffler for a hermetic refrigerant compressor, the suction muffler comprising an inlet for flowing refrigerant into the suction muffler, and an outlet for allowing refrigerant to flow out of the muffler, the suction muffler further comprising two muffling chambers for muffling wherein the two damping chambers each have a bottom and wherein a wall member is provided to separate the two damping chambers in the region of their bottoms for the refrigerant from each other.
  • Hermetically sealed refrigerant compressors have long been known and are mainly used in refrigerators or shelves.
  • the refrigerant process as such has also been known for a long time.
  • Refrigerant is heated by energy intake from the room to be cooled in an evaporator and finally superheated and pumped by the refrigerant compressor with a piston-cylinder unit to a higher pressure level, where it emits heat through a condenser and a throttle, in the one Pressure reduction and the cooling of the refrigerant takes place, is transported back into the evaporator.
  • suction pipe coming directly from the evaporator during an intake stroke of the piston-cylinder unit.
  • the suction pipe opens in known hermetically sealed refrigerant compressors usually in the hermetically sealed compressor housing - usually in the vicinity of an inlet of a suction muffler (also known as Muffler), from where the refrigerant in the suction muffler and through this to a suction valve of the piston-cylinder Unit flows.
  • the suction muffler serves primarily to keep the noise level of the refrigerant compressor during the intake as low as possible.
  • Known suction muffler usually consist of several volumes or damping chambers, which communicate with each other.

  • the separators are formed only by suitably inclined bottoms of the damping chambers. So that liquid can collect in the separators due to gravity, connecting passages are provided between the damping chambers. The fluid is sucked through the labyrinthine structure of the suction muffler, in particular also through the connecting passages, which ultimately leads to the separation of the liquid portions of the fluid.
  • a disadvantage of this solution is that sound can escape from the individual damping chambers via the connecting passages, which has a negative effect on the sound and / or noise development.
  • the liquid level in the separators can not be so high in practice that it comes to a closure of the connecting passages. On the one hand, so much liquid is actually absent. On the other hand, such a closure of the connecting passages would have fatal effects on the noise or noise, since the sucked fluid is still through the connecting passages would be sucked and thereby cause a strong bubbling.
