Definitions

  • the invention relates to a refrigeration system with at least two compressors connected in parallel, which in each case suck in the medium to be compressed via in each case one suction line from at least one suction collecting tube arranged upstream of the compressors.
  • Object of the present invention is to provide a refrigeration system in which the mentioned disadvantages are avoided.
  • a refrigeration system which is characterized in that the compressor housing via at least one U-tube-shaped oil equalization line are connected to each other and at least one additional line to the suction manifold.
  • the lines connecting the compressor housing and the suction collecting pipe are arranged at the lowest point of the suction collecting pipe.
  • the inlet openings of the suction lines leading from the suction collecting tube to the compressors are arranged in the upper region of the suction collecting tube.
  • This structural design of the refrigeration system according to the invention ensures that an intake of oil via the suction lines in the compressor can be largely avoided.
  • a further advantageous embodiment of the refrigeration system according to the invention is characterized in that a respective filter device is arranged in the lines between the compressor housings and the suction manifold.
  • the figure shows three compressors V1 to V3 and a suction manifold S.
  • the medium to be compressed via line 1, which is divided into two lines 2 and 2 ', the suction manifold S supplied.
  • the medium to be compressed is supplied to the compressors V1 to V3 via the suction pipes 3, 3 'and 3.
  • "Oil entrained via the pipes 1, 2 and 2' accumulates at the bottom of the suction collecting pipe S.
  • the compressed medium becomes supplied from the compressors V1 to V3 via the pressure lines 4, 4 'and 4 "in a pressure manifold 5 and over this, for example, one or more, not shown in the figure, cooling points.
  • the pressure equalization between the compressor housings V1 to V3 takes place via these connecting lines 6, 6 'and 6 "and the suction manifold S. Furthermore, these connecting lines 6, 6' and 6" each have a filter device F1 to F3 which serve to remove dirt particles. on.
  • the refrigeration system according to the invention enables the realization of a reliable oil supply of all compressors, since the oil balance is always connected to a pressure equalization. Regardless of the current operating conditions of the compressors and the refrigeration system (full, partial load operation), a reliable oil supply of all compressors can thus be guaranteed at all times.

Claims (4)

  1. Installation frigorifique, avec au moins deux compresseurs montés en parallèle, qui aspirent chacun par une conduite d'aspiration le fluide à compresser à partir d'au moins un tube collecteur monté en amont des compresseurs, les boîtiers (V1, V2, V3) des compresseurs étant reliés entre eux par au moins une conduite d'équilibrage d'huile (7, 8, 8', 8") formant un tube en U, caractérisée en ce que les boîtiers des compresseurs sont reliés au tube collecteur (S) par au moins une conduite supplémentaire (6, 6', 6") qui sert à l'équilibrage de la pression entre les zones de la conduite d'équilibrage d'huile (7, 8, 8', 8") reliées chacune aux boîtiers des compresseurs (V1, V2, V3).
  2. Installation frigorifique selon la revendication 1, caractérisée en ce que les conduites (6, 6', 6") reliant les boîtiers (V1, V2, V3) des compresseurs et le tube collecteur (S) sont disposées au point le plus bas du tube collecteur (S).
  3. Installation frigorifique selon la revendication 1 ou 2, caractérisée en ce que les ouvertures d'entrée des conduites d'aspiration (3, 3', 3") menant du tube collecteur (S) aux compresseurs (V1, V2, V3) sont disposées dans la zone supérieure du tube collecteur (S)
  4. Installation frigorifique selon l'une des revendications précédentes, caractérisée en ce qu'un dispositif de filtrage (F1, F2, F3) est disposé dans chacune les conduites (6, 6', 6") entre les boîtiers (V1, V2, V3) des compresseurs et le tube collecteur (S)
