Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device for carrying it out.
  • a separate device with a compressor is known for the disposal of refrigerant circuits, which in particular contain environmentally harmful refrigerants based on chlorofluorocarbons (DD-PS 902 511), in which filters and a condenser are switched into a pipeline on the pressure side of the compressor opens into a container for the condensed refrigerant.
  • the procedure is such that the compressor is connected with its suction side to the refrigerant circuit to be disposed of.
  • the refrigerant is sucked out of this refrigeration cycle, which contains at least one condenser, a throttle element, an evaporator and a compressor.
  • the disposal facility provided for this requires a high level of equipment, which can only be transported with difficulty and therefore z. B. is only of limited use for customer service.
  • the invention is based on the object of specifying a method according to the preamble of claim 1 and a device for carrying it out, by means of which simplified disposal of a refrigerant circuit can be carried out.
  • a normally closed, but then openable valve can be provided during the manufacture of the device, which valve is provided with connecting means for the collecting container.
  • a piercing valve can also be attached to the removal point, which is connected to the collecting container.
  • a shut-off device in the form of a shut-off valve or a pinch point can also be provided during the manufacture of the device.
  • a motor-operated compressor 1, a condenser 2, an expansion valve 3 and an evaporator 4 leading back to the compressor 1 are connected in series in a closed refrigerant circuit.
  • a removal point 6 for the refrigerant is provided immediately after the compressor 1 in the area of the downstream pressure pipe 5.
  • a closed container 8 for refrigerant can be connected via a valve 7 that is closed in normal operation.
  • the valve 7 can already be used in the production of the refrigerant circuit, but it is also possible to use a piercing valve that can be retrofitted to the pressure pipe 5.
  • the piercing valve 7 is connected to the collecting container 8, which does not have to be part of the device to be disposed of, but is designed to be reusable for customer service and disposal processes.
  • a shut-off device 9 is switched on, which is open in normal operation and is only closed when it is disposed of.
  • This shut-off device is preferably a manually operated shut-off valve, which is already installed during the manufacture of the refrigerant circuit.
  • the shut-off element 9 can, however, also be a tube section of the refrigerant circuit which can be squeezed together in cross section and which is only compressed to the extent that the refrigerant circuit is interrupted when it is disposed of.
  • the compressor 1 assigned to the refrigerant circuit can be started after opening the valve 7.
  • the refrigerant still present in the refrigerant circuit is drawn off and pumped into the collecting container 8.
  • the valve 7 or a valve assigned to the collecting container 8 can be closed.
  • the valve 7 is separated from the refrigerant circuit after the disposal process and is used for closing the collecting container.
  • the refrigerant collected in the receptacle 8 can be introduced into the refrigerant circuit, if necessary via a filter to be switched on, via the tapping point 6 and the valve 7 or via a filler neck 10 provided on the housing of the compressor 1. Otherwise, the collecting container 8 is fed to a reprocessing point.
