Definitions

  • the invention relates to a method for supplying oil to the compressor of an air conditioner.
  • the invention is based on the object, in particular for a reciprocating compressor with a constant stroke, for example according to the not vorverred parallel patent application EP 04405737.0 to find suitable method for its uniform supply of lubricating oil and which is adapted to keep the circulating current of the working medium of the air conditioner circulating constant amount of oil to an optimal, small size.
  • the illustrated device 1 has a two superimposed spaces enclosing, designed for pressures of CO 2 -Air conditioning, solid housing 2, of which the upper forms a cyclone chamber 3 and the lower an oil reservoir 4.
  • the housing 2 of the device 1 may also be enclosed in suction-side arrangement in the housing of a compressor, not shown, that the lower portion of the compressor housing acts as an oil reservoir and a closed oil reservoir 4 according to the illustrated embodiment of Invention is unnecessary.
  • the cyclone chamber 3 is formed by a preferably horizontally extending bore 5 and encloses coaxially one of the outflow serving central channel 6. This is provided as a bore in a massive lateral closure body 7 and is in a subsequent to this and projecting into the cyclone chamber 3 pipe socket. 8 continued.
  • the cylindrical outer surface 9 of the closure body 7 is fitted in a coaxial with the bore 5 receiving bore 10 of the housing 2 and a 0-ring 11 takes over the additional sealing of the cyclone chamber third
  • the oil drain 20 expediently opens in a leading to the bottom of the compressor housing channel, so that contact with moving parts of the compressor drive is prevented and a spin-back of Oil in the suction chamber of the compressor and thus a quantity uncontrolled oil supply is excluded.
  • an oil suction pipe 22 leads upwards and is connected via a radial bore 23 and a nozzle bore 24 adjoining this in the closure body 7 with the central channel 6 of the cyclone chamber 3.
  • the negative pressure formed by the outflow from the cyclone chamber 3 in the central channel 6 causes an ejector-like extraction of oil from the oil reservoir 4 via the oil suction tube 22.
  • a pressure equalization channel is provided between the oil reservoir 4 and an extended outflow region 27 of the central channel 6 through mutually equiaxed bores 28 and 29 formed in the wall of the oil storage space and in the closure body 7.
  • an oil separator 30 is provided in the oil reservoir 4 before the pressure equalization channel 28,29, in which labyrinthine deflections are imposed on a gas flow.
  • the suction opening 25 of the ⁇ lsaugrohres 22 is located at a distance above the bottom 26 of the oil storage chamber 4, so that suction of dirt particles is prevented, which is separated in the cyclone chamber 3 and passed through the oil drain 20 into the oil reservoir 4.
  • the amount of uniformly recycled in the circulation of the operating medium from the oil reservoir 4 oil be determined by a suitable choice of the diameter of the nozzle bore 24, so that by trial runs of the air conditioning, the oil supply to the compressor to an optimum Value can be set.
  • the smallest possible proportion of oil in the operating medium flow is to be set in order to prevent an excessively large proportion of oil from impairing the efficiency of the air conditioning system.
