Description

    THERMALLY INSULATIVE INNER LINING FOR USE IN AN EXHAUST SILENCER OF A HERMETIC RECIPROCATING COMPRESSOR
  • The present invention relates to a hermetic reciprocating compressor for use in a refrigeration appliance, in particular a domestic refrigerator. The present invention more particularly relates to a technique for improving a thermodynamic efficiency of the hermetic reciprocating compressor.
  • In a conventional hermetic reciprocating compressor, the exhaust silencer is usually formed into the cylinder block. In such configuration, the compression chamber and the exhaust silencer are typically connected via an exhaust refrigerant passage formed into the cylinder block. Thereby, a compact configuration is attained.
  • CN1769694 (A) discloses a hermetic reciprocating compressor. In this compressor the exhaust silencer is formed into the cylinder block.
  • A drawback of this configuration is that in the compression phase the thermal energy of the hot and pressurized refrigerant exhausted from the compression chamber is partly dissipated to the cylinder block as it is conveyed via the refrigerant passage into a cavity of the exhaust silencer. Thus, the temperature of the refrigerant inside the cavity decreases and the thermodynamic efficiency of the overall refrigeration cycle degrades.
  • A further drawback of this configuration is that with the commencement of the subsequent suction phase the heat dissipated to the cylinder block is partly transferred to the refrigerant being conveyed into compression chamber. Thus, a density of the refrigerant taken into the compression chamber decreases and a thermodynamic efficiency of the overall refrigeration cycle degrades.
  • An objective of the present invention is to overcome the aforementioned problems of the prior art and provide a technique which improves the thermodynamic efficiency of the hermetic reciprocating compressor.
  • This objective have been achieved by the thermally insulative inner lining as defined in claim 1, the hermetic reciprocating compressor as defined in claim 11, and the refrigeration appliance as defined in claim 12. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
  • In the technique of the present invention, the thermodynamic efficiency is improved by utilizing a thermally insulative inner lining inside the exhaust silencer of the hermetic reciprocating compressor for reducing a heat transfer from the refrigerant inside the cavity of the exhaust silencer to the metal case enclosing the cavity. The thermally insulative inner lining also has a function to damp the acoustic vibrations of the refrigerant.
  • In an embodiment, the thermally insulative material of the inner lining has a coefficient of thermal conductivity which is lower than that of the cylinder block. In a version of this embodiment, thermally insulative material is plastic. In another version of this embodiment, the plastic is polyamide or one of its derivatives.
  • In another embodiment, thermally insulative inner lining has a capsule-like shape which from-fittingly matches an inner surface of the exhaust silencer.
  • By virtue of the thermally insulative inner lining, the thermodynamic efficiency of the hermetic reciprocating compressor has been improved.
  • Additional advantages of the thermally insulative inner lining of the present invention and the hermetic reciprocating compressor of the present invention will become apparent with the detailed description of the embodiments with reference to the accompanying drawings in which:
  • Figure 1 is a schematic partial perspective view of a hermetic reciprocating compressor according to an embodiment of the present invention;

  • Figure 3 is a schematic cross sectional partial view of the hermetic reciprocating compressor shown in Figure 2, taken along the line A-A;
  • Figure 4 is a schematic enlarged side view of the thermally insulative inner lining shown in Figures 1 to 3;
  • Figure 5 is a schematic cross sectional view of the thermally insulative inner lining shown in Figure 4, taken along the line B-B;
