Definitions

  • the refrigerant evaporated in the refrigeration consumers F and F 'of the normal refrigeration cycle is then fed via the suction line G to the compressor unit H and compressed therein to the desired pressure between 10 and 25 bar.
  • the compressor unit H is designed to be single-stage and has several compressors connected in parallel.
  • the object is achieved in that in the intermediate between the condenser and the collecting intermediate relaxation device, a relaxation of the refrigerant to a (intermediate) pressure of 5 to 40 bar.
  • FIG. 2 a composite refrigeration system in which a possible embodiment of the refrigeration cycle according to the invention is realized.
  • a procedure is described in which as a refrigerant HFC (s), HFC (s) or CO 2 can be used.
  • the pressure line 7 is connected or connectable to the line or line sections 2 or 2 ', 2 "connecting the condenser 1 and the collection container 3.
  • refrigerant is withdrawn from the collector 3 and the refrigerant consumers or their heat exchangers E2 and E3 supplied. This is preceded by a respective expansion valve b and c, in which the refrigerant flowing into the refrigeration consumer is expanded.
  • the refrigerant evaporated in the refrigeration consumers E2 and E3 is then fed back to the compressor unit 6 via the suction line 5 or sucked out of the evaporators E2 and E3 by the latter.
  • FIG. 3 1 shows an embodiment of the refrigeration cycle according to the invention or of the method according to the invention for operating a refrigeration cycle, in which the refrigerant drawn off from the collecting container 3 via the line 4 is subjected to supercooling in the heat exchanger E5.
  • the temperature interval between the suction and liquid line or the circulating refrigerant therein may be too low to realize an internal heat transfer for the required supercooling of the refrigerant flowing in the liquid line.
  • FIG. 4 shows a further embodiment of the refrigeration cycle of the invention or the inventive method for operating a refrigeration cycle.
  • the FIG. 4 only a part of the in the FIG. 2 and 3 illustrated refrigeration circuit according to the invention shown.
  • the method according to the invention for operating a refrigeration cycle further develops that at least a partial flow of the flash gas withdrawn from the collecting container is at least temporarily overheated against at least a partial flow of the compressed refrigerant.
