Definitions

  • the invention relates to a refrigerant circuit or mixed refrigerant circuit, comprising at least one compressor, at least one condenser, at least an evaporator and at least one expansion device in the form of a Capillary.
  • the invention relates to a refrigerator and / or freezer with at least one Refrigerant circuit or mixed refrigerant circuit.
  • the invention relates to a method for operating a generic refrigerant circuit or mixed refrigerant circuit.
  • Plug-in refrigerators and / or freezers are refrigerators and / or freezers too provided, all the aggregates that are used to create a (deep) cooling atmosphere are required within the furniture.
  • plug-in cooling and / or Freezer units have the great advantage that they are quicker and easier to put in Can be put into operation and a high degree of flexibility when building and converting enable a retail store.
  • generic Refrigerant (mixed) circuits for use in household refrigeration cabinets.
  • the object of the present invention is a generic refrigerant circuit or refrigerant mixture circuit to specify in which the above Pressure equalization can be avoided.
  • a Refrigerant (mixed) circuit within a refrigerator and / or freezer the heat input into the refrigerator or freezer and, as a result, the required cooling capacity requirements can be reduced.
  • a generic refrigerant circuit or To specify the mixed refrigerant circuit is a refrigerant circuit or Refrigerant mixture circuit proposed, which is characterized in that in the line section of the refrigerant circuit or mixed refrigerant circuit, in which the expansion device is arranged, between the condenser and the evaporator is arranged at least one shut-off valve.
  • the generic refrigerator and / or freezer is characterized in that it at least one refrigerant circuit according to the invention or Has refrigerant mixture circuit.
  • shut-off valve prevents when the Compressor effectively and reliably balances the pressure via the capillary between the low and high pressure side of the refrigerant (mixed) circuit.
  • the invention further relates to a method for operating a generic refrigerant circuit or mixed refrigerant circuit.
  • shut-off valve between 5 and 600 Seconds, preferably between 30 and 90 seconds, before resuming Switch on the compressor.
  • the shut-off valve during a defrost phase open at least temporarily.
  • This embodiment of the method according to the invention enables one Reduction of electrical heating power.
  • the heated and evaporated in the evaporator 7 via line 8 evaporated refrigerant (mixture) withdrawn, compressed and via line 2 the Condenser 3 supplied.
  • the refrigerant (mixture) for example against ambient air - liquefied and then again via line 4 already mentioned evaporator 7 supplied.
  • the evaporator 7 is connected upstream in the Line 4 arranged a relaxation device in the form of a capillary 6.
  • a so-called inner heat exchanger 5 can also be provided in which a heat exchange between the supplied to the evaporator 7 and that of the evaporator 7 removed refrigerant (mixture).
  • shut-off valve 9 is arranged.
  • Refrigerant (mixed) circuit has the line section between the Shut-off valve 9 and the expansion device 6 have a length of at least 600 mm on.
  • the invention makes it possible to reduce the heat input in refrigeration and / or freezer furniture have a refrigerant (mixture) circuit according to the invention, reduce and thereby reducing the cooling capacity requirement. Also those that have occurred so far Temperature fluctuations when switching the refrigerant (mixed) circuit reduced, which makes the temperatures within the goods rooms more appropriate Refrigerators are evened out. This will especially expire temperature-sensitive food counteracted.
