Definitions

  • the present invention relates to a compressor that comprises a muffler.
  • the movement of the refrigerant fluid is a significant source of noise.
  • the sound energy originating from the movement of the refrigerant fluid is transmitted to the compressor casing and is dispersed to the outside environment as compressor noise.
  • the use of a muffler produced from plastic material that enables the sound power level to be decreased is known.
  • the material of the muffler disposed inside the compressor must have high chemical resistance against the oil and fluid included in the compressor.
  • the heat formed at the motor and piston heats the compressor muffler and hence the gas inside by radiation and this situation decreases compressor efficiency. Therefore, the muffler has to be produced from a material that both has high chemical resistance and that decreases heat transfer by radiation by reflecting the infrared rays.
  • a muffler suitable to be used in the compressor comprises polybutylene terephthalate (PTB) and glass fiber.
  • PTB polybutylene terephthalate
  • the aim of the present invention is the realization of a compressor, whereof the energy efficiency is increased.
  • the compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a muffler that prevents noise.
  • the muffler is produced from the mixture of polybutylene terephthalate (PTB), glass fiber and a material that almost entirely reflects the infrared rays that fall on its surface.
  • the mechanical resistance of PBT is increased with glass fiber. Since heating of the muffler by radiation is not realized by means of the reflective material, the temperature of the fluid passing through the muffler does not increase and thus the compressor efficiency is prevented from decreasing.
  • the muffler comprises a material in a percentage between 0.1 and 15 by weight, having the feature of highly reflecting the infrared rays.
  • the material having the high infrared ray reflecting feature is a metal oxide like Al 2 O 3 , TiO 2 , ZrO 2 , SiO 2 , B 2 O 3 .

  • the material with high infrared ray reflective feature is a type of nitrite such as Si 3 N 4.
  • the material with high infrared ray reflective feature comprises glass spherules with average spherule diameter between 3 ⁇ m and 40 ⁇ m that are coated with metal oxide pigments like TiO 2 , SnO 2 or CeO 2 to improve their reflective properties.
  • the diameters of glass spherules are variable so as to reflect infrared rays in different wavelengths.
  • the material with high infrared ray reflective feature is Bismuth Vanadate (BiVO 4 ) based, having near infrared (NIR) reflective feature with particle sizes between 0.2 ⁇ m and 10 ⁇ m.
  • Bismuth Vanadate (BiVO 4 ) which is an inorganic pigment, is a material with high chemical resistance.
  • the material with high infrared ray reflective feature is silicon carbide having particle sizes between 0.5 ⁇ m and 10 ⁇ m.
  • the muffler of the present invention the mechanical and chemical resistance of which is increased by the PBT and glass fiber mixture comprises a material with high infrared ray reflective feature.
  • the rays in infrared wavelength are absorbed less on the muffler surface and reflected and the temperature of the gas inside the muffler is prevented from increasing.

  • PBT polybutylene terephthalate
  • Polybutylene terephthalate (PBT) that has chemical resistance to the oil and fluid inside the compressor (1) is merged with glass fiber and the mechanical resistance of the muffler (2) is improved.
  • the muffler (1) comprises a material, together the PBT and glass fiber mixture, with high reflective properties, that prevents heating of the muffler (2) by radiation and that reflects the infrared rays almost entirely without absorbing.

  • the average particle size of the material with high infrared ray reflecting feature is between 3 ⁇ m and 100 ⁇ m.
  • the particle size dispersion of the material with high infrared ray reflecting feature is heterogeneous and thus heat transfer between particles by way of conduction is low.
  • heat transfer by radiation and conduction is decreased and the increase in the temperature of the gas circulating inside the compressor (1) is prevented.
