Definitions

  • This invention relates to a compressor wherein a suction muffler minimizes the noise generated during the refrigeration cycle by the refrigerant.
  • cooling is achieved by circulating a refrigerant in a cycle that generally consists of a condenser, which transfers the heat out, a pressure reducer used to regulate the pressure, an evaporator absorbing the heat and a compressor.
  • a compressor used in the afore-mentioned cycle, suction mufflers are utilized whereby the refrigerant used to achieve the cooling reaches to the cylinder block without being heated and the noise that might be generated by the refrigerant is prevented.
  • the suction muffler is generally manufactured from plastic material and located either on the cylinder head or between the cylinder head and the valve plate.
  • the refrigerant- sucked reaches-a cylinder block- by- passing- through a muffler wherein its portion forming the suction manifold is placed inside the cylinder head. In the meantime it is necessary to minimize the noise at different frequencies generated.
  • the aim of the present invention is the realization of a compressor comprising a suction muffler whereby the noise that is generated by the refrigerant is minimized.
  • the circulation of the refrigerant used to realize the cooling is achieved by means of a compressor (1).
  • the compressor (1) comprises a cylinder (2) which provides the pumping of the refrigerant in it, a cylinder head (3) located on the cylinder (2), through which the refrigerant that is sucked and discharged is circulated, a valve plate (5) on which the cylinder head (3) is placed, a suction muffler (4) preferably made of plastic material, which ensures that the refrigerant with reduced acoustical energy circulated inside it reaches the cylinder block without being heated and that the noise which might be generated by the refrigerant is prevented.
  • the suction muffler (4) comprises a muffler head (8) whereby the muffler (4) is attached to the cylinder head (3), a muffler outlet opening (6) located above the muffler head (8) and providing the refrigerant to pass to the cylinder (2), at least two muffler chambers (12) having different volumetric resonance frequencies to achieve acoustic attenuation at different frequencies, wherein acoustical energy is reduced, a suction opening (9) permitting the refrigerant to enter through, a flow pipe (10) preferably with quadrangular cross-section, placed across the suction opening (9) and the muffler outlet opening (6) and, the ends of which open to different muffler chambers (12), an aperture (7) on the flow pipe (10), at least one attenuation conduit (13) preferably with circular cross-section, wherein its portions in the muffler chambers which its inlet and outlet openings communicate with, have different cross-sectional areas and whereby the connection between the muffler chamber
  • the flow pipe (10) comprises a flow pipe inlet opening (14) located across the suction opening (9) and a flow pipe outlet opening (15) located across the muffler outlet opening (6).
  • the attenuation conduit (13), which communicates the muffler chambers (12) by connecting them, comprises an attenuation conduit inlet opening (16), which, extending to one of the muffler chambers (12), which is closer to the suction outlet opening (6) and, attenuating the sound waves at undesired frequencies by the cross-sectional area (A5) thereof and; an attenuation conduit outlet opening (17) with a different cross-sectional area (A6) than that of the attenuation conduit inlet opening (16).
  • the cross-sectional area which the flow passes through continuously increases downstream, from the suction opening (9) on the suction muffler (4) to the suction outlet opening (6), in order to minimize the factors which would retard the flow of the refrigerant and would reduce thermodynamic efficiency of the suction muffler (4) by causing pressure losses. Thereby, it is minimized that the uniform flow is disturbed due to the-reductions in the cross-section, to the boundary layer conditions or, while passing by inclined or bent regions.
  • cross-sectional area (A1) of the suction opening (9) outside the muffler chamber (12), is smaller than that (A2) of the flow pipe inlet opening (14), and cross-sectional area (A3) of the flow pipe outlet opening (15) is smaller than that (A4) of the muffler outlet opening (6) inside the muffler chamber (12).
  • the suction muffler (4) comprises a muffler chamber (12) communicating with the suction opening (9), a second muffler chamber (12) with a different volumetric resonance frequency communicating with the muffler outlet opening (6), a third muffler chamber (12) with a different volumetric resonance frequency located between the two other muffler chambers (12) and an attenuation conduit (13) communicating with the third and second muffler chambers (12) (Fig. 3).
  • the suction muffler (4) comprises a muffler chamber (12) communicating with the suction opening (9), a second muffler chamber (12) with a different volumetric resonance frequency communicating with the muffler outlet opening (6) and, an attenuation conduit (13) communicating with the first and second muffler chambers (12) (Fig. 4).
  • the suction muffler (4) comprises a first muffler chamber (12) communicating with the suction opening (9), a second muffler chamber (12) with a different volumetric resonance frequency communicating with the muffler outlet opening (6), a third muffler chamber (12) with a different volumetric resonance frequency than that of the two other muffler chambers (12) and which is located between the first and the second muffler chambers (12) and, three attenuation conduits (13) which communicate with the third and second muffler chambers (12) and having different cross-sectional areas thereby minimizing the noise at different frequencies (Fig. 5).
  • the suction-muffler (4) comprises-one or more guiding members (11) extending from the suction opening (9) to the first muffler chamber (12) whereby the refrigerant sucked is routed to the flow pipe (10) and the refrigerant in the flow pipe (10) is routed to the muffler outlet opening (6) (Fig. 6).
  • the suction muffler (4) comprises a first muffler chamber (12) communicating with the suction opening (9), a second muffler chamber (12) with a different volumetric resonance frequency communicating with the muffler outlet opening (6), a third and fourth muffler chambers (12) with different volumetric resonance frequencies and which are located between the first and the second muffler chambers (12), an attenuation conduit (13) communicating with the third and second muffler chambers (12), and another attenuation conduit (13) communicating with the second and fourth muffler chambers (12) and having different cross-sectional areas than that of the other one thereby minimizing the noise at different frequencies (Fig. 7).
