Definitions

  • This invention relates to a compressor preferably used in refrigerators, wherein a muffler minimizes the noise generated by the refrigerant during the refrigeration cycle and a cylinder head is used to attach the muffler to the cylinder.
  • 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 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.
  • thermodynamic efficiency While attempting to minimize the noise generated during this period, it is necessary to improve thermodynamic efficiency. However, heat transfer occurs at the section where the cylinder head and the muffler head are connected, such that the refrigerant, and as a consequence thermodynamic cycle is affected.
  • the cylinder head is manufactured in single piece and a portion of it is in full contact with the surfaces of the muffler that form the suction manifold.
  • the refrigerant reaches the cylinder by passing the muffler wherein its portion forming the suction manifold is located in the cylinder head.
  • the temperature of the refrigerant taken into the cylinder rises because of the temperature gradient formed at the cylinder head as a result of discharge of the gas priorly to the exhaust manifold of cylinder head after leaving the cylinder, wherein both the pressure and temperature of the gas are increased by the compression process in the cylinder.
  • the rise in the temperature of the refrigerant causes its volume to increase thereby resulting in compression of less amount of gas in a standard stroke volume and, decrease of volumetric efficiency of the compressor.
  • the aim of the present invention is the realization of a compressor with increased volumetric efficiency, wherein means are provided to transfer the refrigerant to the cylinder without being heated at the section where the cylinder head and the muffler head are connected.

  • the air between the suction muffler (4) and the muffler head (8) is used as an insulator (10) and functions like an insulating wall or insulating chamber.
  • the contact surface of the muffler head housing (7) and the muffler head (8) is decreased thereby ensuring the intake of the refrigerant to the cylinder at a low temperature and thus at higher density and, increasing the performance of the compressor (1).
